Land Rover Defender TD5 turbo wastegate fix

- When you own a Land Rover Defender TD5 or any other LR for that matter, you do need to keep up on the maintenance. So when I was checking over the engine I found the waste gate mechanism seemed to be jammed. I've not worked on this part of the engine so it was a bit of a learning curve. I removed the actuator from the wastegate arm to see which had failed, the actuator or the arm. In my case the arm mechanise had gone bad. The shaft running into the manifold had seized. Very expensive! Luckily though with a 17mm spanner and a tin of WD40, slowly I managed to work the shift loose, just a little at a time.
A few minutes of careful persuasion totally freed off the arm. I was unable to find any information exactly how this arm should be refitted. Was there any calibration required? I'm still not sure but what I did was the following. I re-attatched the actuator to the arm after bolting in the actuator using the 2 10mm nuts. I took up all the slack in the arm using the thumb screw then gave it another turn and half. As stated in the video, comparatively speaking, the performance is now out of this world. I can only assume the wastegate had been stuck open a tad preventing me from getting full boost. This fix worked for me, and is still good, but don't go tweaking the turbo unless you know what you are doing or are prepared for things to go bad!
* Update April 2022. The fix is still going strong with no need to revisit the problem, very happy*
Although I didn't need to replace it here is a link to an actuator currently for sale for around £35 on eBay:

Same problem with my 90 td5 , main symptom is it feels like it’s missing because the ecu shuts fuel off as you power on , freed of the waste gate and hay ho it’s better than it’s ever been , happy days 👍
Hi Roger, it was a night/day difference when I did mine. Felt like a new truck! I’m glad you got yours running better. Thanks for watching 👍🏽
Thanks, mate. will check that out.
No problem 👍
Thank you. Might have solved my problem.
Great to hear. I do go back to mine now and again to check it’s still ok and so far so good! Thanks for the feedback and for watching 👍🏽
Great video, thanks for sharing this!
Glad you enjoyed it! Thanks for watching 👍🏽
Thanks for the video mate! Great content! 👍🏼
Glad you liked it! 👍🏽
I’ve trouble with mine now - mine moves freely but very the first bit is very stiff - so I think (similar to yours) mine is sticking open a little bit. Not 100% consistent - but sometimes it really struggles to boost - almost like having ridiculous turbo lag.
Sounds at if you are loosing some boost straight to the exhaust. When I freed mine off it was a night and day difference. Without stripping it though I'll never know if it's totally shut. Thanks for watching and good luck.
Hi, great vid. Do you know how I can test if the arm is stuck or not without compressed air?
Hi, on mine there is an adjustable linkage. If you note how far the nut is threaded onto the threaded bar (so you can refit in exactly the same position) then undo it. You should be able to swing the arm. On mine it was stuck and from memory I freed it off with a spanner and WD40. There is no need to remove anything (after you have released the nut/bar linkage) , you can get at the arm with the spanner, but it's a bit fiddly! If the arm moves freely all is good but you would still need an air line to check the actuator works. Keep the pressure low or else you will damage the actuator. Thanks for watching 👍🏽
Roughly how many threads on the arm do you leave before locking up with the nut?
Hi Breakit46, on mine I have 17 threads exposed that you can see and a distance between the lock nut (on the actuator side of the nut) and the actuator body is approx 46mm. I hope that helps a little,. Thanks for watching 👍🏽
@@MikeMakesIt thanks for the reply, I have made a note of that. I freed up the waste gate today and uncoupled by taking out circlip, refitting I had to wind out the rod to ease re fitting.
Thats fine. Good luck. When I put mine back together I tightened it up enough so the actuator was tugging a little on there gate thus making sure it was closed. Seem to work for me and has been running for a long time now!
@@MikeMakesIt will do the same, I measured mine it was 45mm best I could tell. We have a weak compressor so will try blow air thru and see if all is free. Will then do as you did, it makes sense. Thanks for your help.
