Chris, there isn’t any golden rule for when they might fail, the plastic degrades over time as well as miles. As the car gets older and with more miles the risk is higher. Might be a sensible precaution before such a long trip planned, especially if you are planning to keep the car long term. The consequences of them failing can mean a ruined engine and that’s why must people get it done. Hope that helps, Regards Damian

I am owning for one year an XK8 Cab manufactured in April 2000 with 84000 kms on the odometer (this mileage should be real according to the yearly technical inspection records). So I assume the secondary timing chain tensioners are Rev2 (plastic ones with spring). In order to avoid future troubles, I would like to upgrade those tensioners to Rev3 (metal cylinders ones). The car has now a mileage of 92000 Kms and as a matter of fact, I did not hear so far distribution chain rattling or suspicious noises. I plan to upgrade the distribution but, since it is a quite heavy and compex dismounting/remounting process to make an overall change, for the time being, I'd like to limit the operation to the secondary chain tensioners (the said most subject to problem). From the tutorial EP48 I have watch, l wonder if this can be done by just removing the upper parts of the engine; I mean without desmounting the front carter that gives access to the primary chains, guides and tensioners. Is anyone knowing if this is feasible or not?
Çavapaslatête, It is possible see the video link below. I haven't used this method but you remove the cam. It is possibly the cheapest method of doing the job. I would recommend doing the secondary tensioners as soon as possible. If you are keeping the car probably better to do the complete timing chains, tensioners and guides. Hope that helps, regards Damian. th-cam.com/video/ECC69nXv3N4/w-d-xo.html

Damian thank you for taking the time to answer and for your videos. We were already talking about bore wear and loss of power on my 2001 Jaguar VDP. I do not have the Aj26 I have the AJ27. So would bore wear still factor in to this? I will try to change the fuel filter and then run injector cleaner. It does sound the bore wear (the noise) when I compare it in a youtube video. I was told I would have to replace the block if thats the case.
@tainchains. Your car is a 2001 so hopefully should have the steel liners. you might be very unlucky and have one of the last nikasil engines What is your engine number? The first steel-lined AJ-V8 came off the production line In the year 2000 on August 18th at 10.43am hence the engine number will read: 00 08 18 1043 or more precisely:0008181043. Check your engine number is after this date. There is an interesting article about the subject in Jagrepair.com, see link below. Hope that helps, regards Damian jagrepair.com/NikasilEngineBlocks.htm
May I ask, you mentioned a bad cylinder bore could be responsible for my problems. In you experience is that likely the extent of it or is it possible that my piston will be damaged or???
@tainchains, no sure to be honest. Assume wear of the bore coating will reduce compression. If you have a damaged piston you will probably have no compression or other symptoms ie noising engine rattle or usual tapping. Compression tests might give you some more information. Sorry don't have personal experience of your issue, regards Damioan
@tainchains, doing the timing gear is a very good idea for this age of car but doubt it has anything directly to do with misfiring cylinders. Plugs, coil packs and ECU would be the first items to check in that order. Should be able to spot a faulty plug/coil pack by moving them to another cylinder and seeing if the fault moves with them. Good luck with your repairs, regards Damian
Apologoes for asking for online diagnosis. My X308 was misfiring on cylinders 1-4. Most notably at 50 mph with a sometimes rough idle. It was retimed with a kit. The guy said it had jumped a little. I can still feel a small shudder at 50 mph. Its not nearly as bad. Its very light. I plan to replace the plugs and coils. Any thoughts on the problem being way better but still lightly shuddering at 50 mph?
@tainchains, sorry difficult to diagnose but doesn't sound like anything timing related. More likely to be ignition related plugs, coils or ECU. Have you tried swopping the coil packs over and see it the issue moves to the other cylinders? regards Damian
Is it neccesary to replace the harmonic balancer bolt during this repair. I have heard that it is. The problem is we do not have a replacement and I'm not sure how long it will be to get one.
@tainchains, It is good practice to renew the bolt as due to the large amount of torque required the threads could be stretched or weakened. That said if it has stretched the threads it will be quite clear and you won't be able to use. It is a large bolt and if it hasn't stretched you should be able to feel for this when reusing it. Not recommended but you might get away with it in the short term. Hope that helps, regards Damian
That's an impressive process documentation. It was a great idea to organize all your videos in one. Really amazing. I have an 04 as you know and hope I'll never have to do that job. Sounds like a huge pain in the b.... Do the new upgraded tensioner guides on my model year tend to wear off at some point? Like at 20 years old maybe as you mentioned? Thanks for the videos, outstanding!
Alexander, this video was prompted by you’re feedback about the process and why we need to do certain things. Thanks for the push. There is no definitive answers to changing the timing gear, this is the first time the engines have existed and run for this length of time. I believe it’s reasonable to assume they will last 200,000 miles or 20 years which ever is soonest. But no data. What we can say the failure does cause issues and if you change it you should be ok for a further 20 years or 200, 000miles. Hope that helps. Thanks for the support, regards Damian
@@ODRModurol Thanks D. I appreciate. And I'm sure that will boost your subscription number too. After all TH-cam is for videos so..

It is also a way to let the world know that you can own a jag and not always depends on garages and their insane prices. Thanks, have a great weekend.
I have seen your videos before deciding if I should undergo this project on my xjr or let my mechanic do it. After reviewing I want to do it and these videos have helped me determine the necessary steps to do so. I thank you so much cor this work and all your videos. One question, where could I find the timing kit you used? (Tensioners, guides, chains, fron main seal, and valve cover seals) Thanks in advance and greetings from PR🇵🇷
Walt Gutz, Thank you for taking the time to comment and compliment. Your support is much appreciated. Most kits have the main items but not the front crank oil seal, sump gasket, etc. All parts I used where not in a single kit as can be specific to the year of manufacture and how much else you want to do. I used SNG Barratt and British Car Parts for the main kit and additional items. Just make sure you get the OEM designed chain guides in the main kit you choose. Thanks again for the comment and good luck with doing this work yourself. If you have any more questions as you go along please do not hesitate to contact us, regards Damian
Is there a playlist of all of this? Or could you link to the next video in the description please? I went through your whole channel but it's confusingly set up, no offence (I'm probably being stupid).
@TheTarrMan, Thank you for your interest and feedback. Much appreciated. Edited the layout of the home page this morning added the playlist to it. The whole series of videos on tensioners are labelled EP0 to EP48. There are links at the end of the video but there is also a full playlist, see link attached at the bottom. Hope that helps, regards Damian. th-cam.com/play/PLCgwrY7zZri9guxpk4nUPBYm2itVj4yrv.html
Mario, 2002 is a cross over year, so best to check the engine number or do a visual inspection. All 4.2 litres cars are OK so 2005 is no problem. Good luck with your search, regards Damian
@skelejp9982, sorry not happened to me but check out this thread on Jaguar Forums. Could be any number of things but it has some ideas which might help diagnose the issue. Have you had any work done recently? regards Damian www.jaguarforums.com/forum/xk8-xkr-x100-17/serpentine-belt-pops-off-214046/
@skelejp9982, does it need a new aux belt? There are markings on the tensioner to assess this. Take a look at this video for details at circa 1 minute in, regards Damian th-cam.com/video/nnlGqV9ysJ4/w-d-xo.htmlsi=qNTiktyRNxARTW7c
Jermaine, yes it would be a lot of work to change head gaskets. But hopefully we can find a simply solution it your coolant level issue, regards Damian
Mark, this might help “How long for Jaguar mechanic to change the timing chains, tensioners and guides on an XK8? XKR X100” th-cam.com/users/shortsKc3pJUSTHPE?feature=share , regards Damian
Had another question. My 2001 Vanden Plas X308 was retimed with a kit by a work at home mechanic. I have no idea how these are to be timed. It was misfiring on one entire side cylinders 1-4 before it was redone with a new timing kit. I'm wondering it the chains were put on incorrectly because it seems to have lost some compression and power although the misfires have mostly gone and not no misfire codes. I can still feel a slight misfire around 50-60 MPH. I replaced the plugs and the coils. But still same thing. How can you know for sure if the timing is off?
@tainchains, the cams and crank are both locked in position when you fit the new chains. Its unlikely to have been fitted incorrectly. Might be something else. Compression loss could be due to bore wear of the nikasil coating (if yours is the early engine AJ26). sorry you don't seem to be having any joy with your engine, regards Damian
Thanks so much for taking the time to reply Damian. I think that you might be right about the bore wear. I hope that you are not. The guy who did the timing said it could be the fuel filter is clogged, and needs to be replaced. But the noise sounds similar to bore wear noise whe I check yourube videos on it. Wild a compression test help me determine if its bore wear or not?
I’m looking at a 2000 KXR coupe with 71k miles on it. The gentleman is asking $15k for it and I’m considering buying but want to know if I should opt for a newer year to avoid the plastic guides? Any thoughts?
Willyman, if tensioners haven’t been changed you should be able to negotiate around that being urgently required. Also if it hasn’t had a gearbox oil and filter change. Metal tensioners were built into engines assembled after 13th August 2001. Need to balance these items against the cost of this car and a similar post metal tensioners car. If you get to Post MY2003 XKR’s all have 4.2 litres, 6 speed auto and brembo brakes, generally better specs. Hope that helps and good look with your purchase. Thanks for the comment regards Damian
Tony, yes it is possible to change just the top (secondary tensioners). See this video from @RobertDIY for details th-cam.com/video/ucorMZv6Wgo/w-d-xo.htmlsi=WCB830q0coInJxaL Hope that helps and good luck with the repairs, regards Damian
@@ODRModurol Thank you for your response regarding the timing chain I absolutely appreciate your help and the video helps.I will attempt to carry out the work.
@@ODRModurol Hi I just wanted to give you an update on the top tensioner . I removed the rocker cover from bank 1 and noticed that the chain was tight and secure from the top however I noticed that the bottom was slacking also found a bit of plastic .I removed the tensioner and followed your instructions and changed the tensioner both sides.I was astonished with the result and how quite the engine runs now. I thank you and salute you sir .Thanks
Tony, thanks for the feedback and update on your engine. Really glad to hear you got a good result. Hopefully, will not need to be done again for quite some time, regards Damian
I have a 2001xk8 convertible 170000 miles I changed oil mobile 5w 30w synthetic I could here slight rattle on start up checked secondary tensioner new style very clean. Now I here a loud metal knock not consistent. Can this be the vvt silonod also timing cover inside on outer edges is like washed clean like oils hitting it and making it shine. Any suggestions low budget ordered silonod. Next 10w40w oil clean slump pump.
Robert, slightly thicker 10W40 oil is going to help a bit. Might be the seals within the VVT units themselves not holding pressure. Take a look at this video, is it a similar noise, regards Damian Video link th-cam.com/video/0BAtzYHMLdE/w-d-xo.html
@@ODRModurol iv ordered new silonod I'll install it. I'm still dropping pan to check for anything. And I've got a tethiscope I'm almost positive it's the VVT. And the shiny side of the timing cover is really strange oil could be shooting out of the seals of the VVT. I'll photo the inside and post it. May help someone out. Could be mistaken for rod.
I have read so many different dates about when the timing chains need to be replaced as in most people say if you have a 2002 you have the new not plastic ones others say 2001 others say at the end of 2002 is when they started putting the improved ones in what is the truth?
Eric, the correct answer is the manufacturing date of the engine and not the car. Jaguars AJV8 engine was upgraded to the metal tensioners on 13th August 2001 at 00:00 hrs. The engine number 0108130000 onwards. This was used in several Jaguar models. This is approx model year 2002 for the XK8/R but practically to engine upgrade wasn't coordinated accurately with the XK8 MY upgrade. The only way to be sure is to inspect the Engine number on the engine block. Anything after 0108130000 has metal tensioners. Although the engine uses chains rather than rubber timing belts they do stretch over time. They last a lot longer than belts but the stretch must have some effect on the timing and efficiency. Hope that helps and thanks for the comment regards Damian. Might suggest watching this videoth-cam.com/video/f3wAGev6tPQ/w-d-xo.html
@@ODRModurol I did some research on my engine I can't remember what I looked at but I know I didn't look at the serial number in the engine itself but I came to the conclusion my engine was built to May 2002, My car is a 2002.
@@ODRModurol it's pretty safe to say that if I do not see my inches serial number up top by the thermostat housing area that it is safe for plastic tensioners.
When you talk about problems with primaries now, would this also include later built (like '04 built) engines when they start racking up miles a few years from now? Or maybe I should ask, how many miles are the primaries good for on later engines?
Andork, yes I was talking generally about all the timing gear including the metal tensions. No one really knows as it’s relatively new ground. I think a replacement period of 200,000 miles or 20 years which ever is earlier is reasonable. It is worth noting that the consequence of failure is quite high and therefore best to be cautious. If you do change them all you probably won’t need to worry about them for another 20 years. No definitive answer but hope that helps. Thanks for the comment regards Damian

John, Would suggest taking a look at SNG Barratt website. They are Jaguar classic parts specialists and offer a selection of timing parts and kits for the X100. They sell either OEM or aftermarket OEM quality just choose what you want or can afford. However, I generally get Jag part numbers from SNG B and put it into Ebay to see if you can by the same cheaper. Sometimes you can find the same cheaper but often they are surprisingly competitive. I will put some links below as examples (PS please input your own cars details to ensure compatibility). Thanks for the comment regard Damian

The first steel-lined AJ-V8 came off the production line In the year 2000 on August 18th at 10.43am hence the engine number will read: 00 08 18 1043 or more precisely:0008181043. Check your engine number is after this date. There is an interesting article about the subject in Jagrepair.com, see link below. Hope that helps, regards Damian

May I ask, you mentioned a bad cylinder bore could be responsible for my problems. In you experience is that likely the extent of it or is it possible that my piston will be damaged or???
@tainchains, no sure to be honest. Assume wear of the bore coating will reduce compression. If you have a damaged piston you will probably have no compression or other symptoms ie noising engine rattle or usual tapping. Compression tests might give you some more information. Sorry don't have personal experience of your issue, regards Damioan
Ok. thank you. i am havig the timing done. I had a misfire cylinder 1-4. I'm hoping the timong will correct this. Any thoughts?
@tainchains, doing the timing gear is a very good idea for this age of car but doubt it has anything directly to do with misfiring cylinders. Plugs, coil packs and ECU would be the first items to check in that order. Should be able to spot a faulty plug/coil pack by moving them to another cylinder and seeing if the fault moves with them. Good luck with your repairs, regards Damian
Apologoes for asking for online diagnosis. My X308 was misfiring on cylinders 1-4. Most notably at 50 mph with a sometimes rough idle. It was retimed with a kit. The guy said it had jumped a little. I can still feel a small shudder at 50 mph. Its not nearly as bad. Its very light. I plan to replace the plugs and coils. Any thoughts on the problem being way better but still lightly shuddering at 50 mph?
@tainchains, sorry difficult to diagnose but doesn't sound like anything timing related. More likely to be ignition related plugs, coils or ECU. Have you tried swopping the coil packs over and see it the issue moves to the other cylinders? regards Damian
Is it neccesary to replace the harmonic balancer bolt during this repair. I have heard that it is. The problem is we do not have a replacement and I'm not sure how long it will be to get one.
@tainchains, It is good practice to renew the bolt as due to the large amount of torque required the threads could be stretched or weakened. That said if it has stretched the threads it will be quite clear and you won't be able to use. It is a large bolt and if it hasn't stretched you should be able to feel for this when reusing it. Not recommended but you might get away with it in the short term. Hope that helps, regards Damian
That's an impressive process documentation. It was a great idea to organize all your videos in one. Really amazing. I have an 04 as you know and hope I'll never have to do that job. Sounds like a huge pain in the b.... Do the new upgraded tensioner guides on my model year tend to wear off at some point? Like at 20 years old maybe as you mentioned? Thanks for the videos, outstanding!
Alexander, this video was prompted by you’re feedback about the process and why we need to do certain things. Thanks for the push. There is no definitive answers to changing the timing gear, this is the first time the engines have existed and run for this length of time. I believe it’s reasonable to assume they will last 200,000 miles or 20 years which ever is soonest. But no data. What we can say the failure does cause issues and if you change it you should be ok for a further 20 years or 200, 000miles. Hope that helps. Thanks for the support, regards Damian

I have seen your videos before deciding if I should undergo this project on my xjr or let my mechanic do it. After reviewing I want to do it and these videos have helped me determine the necessary steps to do so. I thank you so much cor this work and all your videos.
One question, where could I find the timing kit you used? (Tensioners, guides, chains, fron main seal, and valve cover seals)
Thanks in advance and greetings from PR🇵🇷
Walt Gutz, Thank you for taking the time to comment and compliment. Your support is much appreciated. Most kits have the main items but not the front crank oil seal, sump gasket, etc. All parts I used where not in a single kit as can be specific to the year of manufacture and how much else you want to do. I used SNG Barratt and British Car Parts for the main kit and additional items. Just make sure you get the OEM designed chain guides in the main kit you choose. Thanks again for the comment and good luck with doing this work yourself. If you have any more questions as you go along please do not hesitate to contact us, regards Damian
Is there a playlist of all of this? Or could you link to the next video in the description please? I went through your whole channel but it's confusingly set up, no offence (I'm probably being stupid).
@TheTarrMan, Thank you for your interest and feedback. Much appreciated. Edited the layout of the home page this morning added the playlist to it. The whole series of videos on tensioners are labelled EP0 to EP48. There are links at the end of the video but there is also a full playlist, see link attached at the bottom. Hope that helps, regards Damian.

So any XK after 2002 definitely has metal parts? Im looking at a sexy Blue convertible 2005
Mario, 2002 is a cross over year, so best to check the engine number or do a visual inspection. All 4.2 litres cars are OK so 2005 is no problem. Good luck with your search, regards Damian
Hello, I have a question.
My auxiliary belt keeps slipping of, on my 00 Super V8.
And my mechanic cannot find the problem, U have any idea?
@skelejp9982, sorry not happened to me but check out this thread on Jaguar Forums. Could be any number of things but it has some ideas which might help diagnose the issue. Have you had any work done recently? regards Damian
www.jaguarforums.com/forum/xk8-xkr-x100-17/serpentine-belt-pops-off-214046/
@skelejp9982, does it need a new aux belt? There are markings on the tensioner to assess this. Take a look at this video for details at circa 1 minute in, regards Damian

this would be a significant chunk of head gasket labor on these cars as well, right?

Does anybody have an idea on how much for a garage to do this job?
Thanks mark

Had another question. My 2001 Vanden Plas X308 was retimed with a kit by a work at home mechanic. I have no idea how these are to be timed. It was misfiring on one entire side cylinders 1-4 before it was redone with a new timing kit. I'm wondering it the chains were put on incorrectly because it seems to have lost some compression and power although the misfires have mostly gone and not no misfire codes. I can still feel a slight misfire around 50-60 MPH. I replaced the plugs and the coils. But still same thing. How can you know for sure if the timing is off?
@tainchains, the cams and crank are both locked in position when you fit the new chains. Its unlikely to have been fitted incorrectly. Might be something else. Compression loss could be due to bore wear of the nikasil coating (if yours is the early engine AJ26). sorry you don't seem to be having any joy with your engine, regards Damian
Thanks so much for taking the time to reply Damian. I think that you might be right about the bore wear. I hope that you are not. The guy who did the timing said it could be the fuel filter is clogged, and needs to be replaced. But the noise sounds similar to bore wear noise whe I check yourube videos on it. Wild a compression test help me determine if its bore wear or not?
I’m looking at a 2000 KXR coupe with 71k miles on it. The gentleman is asking $15k for it and I’m considering buying but want to know if I should opt for a newer year to avoid the plastic guides? Any thoughts?
Willyman, if tensioners haven’t been changed you should be able to negotiate around that being urgently required. Also if it hasn’t had a gearbox oil and filter change. Metal tensioners were built into engines assembled after 13th August 2001. Need to balance these items against the cost of this car and a similar post metal tensioners car. If you get to Post MY2003 XKR’s all have 4.2 litres, 6 speed auto and brembo brakes, generally better specs. Hope that helps and good look with your purchase. Thanks for the comment regards Damian
@@ODRModurol thanks! I still see the vehicle for sale and test drove it, wonderful car! But I think I’ll hold out for a later year.
@@Willyman1942 there is plenty of options out there so drive a few and hold out for exactly what you want. Thanks for the update regards Damian
Thank you I will try and do the job myself is it possible just to change the top tensioner
Tony, yes it is possible to change just the top (secondary tensioners). See this video from @RobertDIY for details th-cam.com/video/ucorMZv6Wgo/w-d-xo.htmlsi=WCB830q0coInJxaL Hope that helps and good luck with the repairs, regards Damian
@@ODRModurol Thank you for your response regarding the timing chain I absolutely appreciate your help and the video helps.I will attempt to carry out the work.
@@ODRModurol Hi I just wanted to give you an update on the top tensioner . I removed the rocker cover from bank 1 and noticed that the chain was tight and secure from the top however I noticed that the bottom was slacking also found a bit of plastic .I removed the tensioner and followed your instructions and changed the tensioner both sides.I was astonished with the result and how quite the engine runs now. I thank you and salute you sir .Thanks
Tony, thanks for the feedback and update on your engine. Really glad to hear you got a good result. Hopefully, will not need to be done again for quite some time, regards Damian
I have a 2001xk8 convertible 170000 miles I changed oil mobile 5w 30w synthetic I could here slight rattle on start up checked secondary tensioner new style very clean. Now I here a loud metal knock not consistent. Can this be the vvt silonod also timing cover inside on outer edges is like washed clean like oils hitting it and making it shine. Any suggestions low budget ordered silonod. Next 10w40w oil clean slump pump.
Robert, slightly thicker 10W40 oil is going to help a bit. Might be the seals within the VVT units themselves not holding pressure. Take a look at this video, is it a similar noise, regards Damian Video link th-cam.com/video/0BAtzYHMLdE/w-d-xo.html
@@ODRModurol iv ordered new silonod I'll install it. I'm still dropping pan to check for anything. And I've got a tethiscope I'm almost positive it's the VVT. And the shiny side of the timing cover is really strange oil could be shooting out of the seals of the VVT. I'll photo the inside and post it. May help someone out. Could be mistaken for rod.
Robert, good stuff, please share your results, we are really interested in your findings, regards Damian
I have read so many different dates about when the timing chains need to be replaced as in most people say if you have a 2002 you have the new not plastic ones others say 2001 others say at the end of 2002 is when they started putting the improved ones in what is the truth?
Eric, the correct answer is the manufacturing date of the engine and not the car. Jaguars AJV8 engine was upgraded to the metal tensioners on 13th August 2001 at 00:00 hrs. The engine number 0108130000 onwards. This was used in several Jaguar models. This is approx model year 2002 for the XK8/R but practically to engine upgrade wasn't coordinated accurately with the XK8 MY upgrade. The only way to be sure is to inspect the Engine number on the engine block. Anything after 0108130000 has metal tensioners. Although the engine uses chains rather than rubber timing belts they do stretch over time. They last a lot longer than belts but the stretch must have some effect on the timing and efficiency. Hope that helps and thanks for the comment regards Damian. Might suggest watching this videoth-cam.com/video/f3wAGev6tPQ/w-d-xo.html
@@ODRModurol I did some research on my engine I can't remember what I looked at but I know I didn't look at the serial number in the engine itself but I came to the conclusion my engine was built to May 2002, My car is a 2002.
@@ODRModurol your knowledge about these cars is very impressive thank you
Eric, thank you for the comments and compliment, regards Damian
@@ODRModurol it's pretty safe to say that if I do not see my inches serial number up top by the thermostat housing area that it is safe for plastic tensioners.
When you talk about problems with primaries now, would this also include later built (like '04 built) engines when they start racking up miles a few years from now? Or maybe I should ask, how many miles are the primaries good for on later engines?
Andork, yes I was talking generally about all the timing gear including the metal tensions. No one really knows as it’s relatively new ground. I think a replacement period of 200,000 miles or 20 years which ever is earlier is reasonable. It is worth noting that the consequence of failure is quite high and therefore best to be cautious. If you do change them all you probably won’t need to worry about them for another 20 years. No definitive answer but hope that helps. Thanks for the comment regards Damian

@@ODRModurol Hi again, Thank you; I have the tools ordered. I'm not sure I'll renew all the bolts (other than the crankshaft) unless any look suspicious, however, I am having difficulty finding the gasket kits and crankshaft bolt on line. Do you have links for all the parts you purchased please? As yours worked I would be much happier using the same parts as you. Kind regards John
John, Would suggest taking a look at SNG Barratt website. They are Jaguar classic parts specialists and offer a selection of timing parts and kits for the X100. They sell either OEM or aftermarket OEM quality just choose what you want or can afford. However, I generally get Jag part numbers from SNG B and put it into Ebay to see if you can by the same cheaper. Sometimes you can find the same cheaper but often they are surprisingly competitive. I will put some links below as examples (PS please input your own cars details to ensure compatibility). Thanks for the comment regard Damian
