So i hope everyone enjoys this one. If you do give it a share! Use this pinned post if you can think of anymore differences. Another one i just remembered is the zleh has a shorter dipstick for more oil capacity.
I would like to add that the LET and LEH conrods are actually different, the LET one has a little oil squirter hole drilled all the way into the bearing which the LEH doenst have because it has proper oil squirters. Also the camshaft sensor plugs are different
Ben Lee well you expect the nuts and bolts on a used car to be dirty and rusty or you’ve never worked on a car before so you will have trouble anyways.

Bloody beautiful mate , thank you so much for going to the time to make such a informative video , I am rebuilding my z20let is Australia now with a garret g30 setup and we will be taking your advice in regards to billet main caps and balancer shaft delete kit , love the small important details of lifter manufacturing by INA , your a legend mate . Thank you
What a mega video! I’m a Vag guy and watching your videos makes me want a Astra GSI Big time! Thanks for your videos Aaron always look forward to watching them.
Cracking video once again,really really love these long in-depth videos of yours, so packed with info will have to watch this one twice 😄 if you ever open your own garage offering rebuilds for these engines all the other garages that do the same would go out of business 😂 can't wait to see next upload 🙏🙌👍
Great video Aaron, amazing work that you do, very interesting and informative, don't think their is any other channel that comes close to your knowledge of an engine 👌😀👍
I don’t own a vauxhall,but I’ve watched you videos for years now, your knowledge is unreal! If my Alfa JTD engine ever goes boom, you might be the guy I’d be ringing, as GM shared a lot of parts with Alfa Romeo at the time.
Another bang on vid bud, why are you not working for a race team or building engines for Courtney, your knowledge on these motors is priceless, fair play to ya. Love watching
Aaron.. again ... your knowledge is amazing. You could read us the telephone directory and I'd listen! Please do a question and answer vid so you can explain where you learnt all this!
Been watching your videos for a while now, the quality and knowledge is always on point! Great information to no, not into Vauxhall’s or evos but still watch haha keep em up 👍🏻
your amazing Arron. i’m a porsche man but love this channel and had my fair share of vauxhall’s myself. your knowledge is excellent second to none mate 👌🏼👌🏼👌🏼👍🏻👍🏻👍🏻
Where do the z20lel and z20ler fit into this? Are they more the same as the let or the leh? Just got myself a twintop astra 2.0 turbo 200bhp from a salvage yard, was smoking badly, fitted new turbo core, service, new breather hoses etc and it's running beautifly now. Then I stumbled across your video for the cam cover gasket as mine had a small leak and changed that too. You really know your stuff 👍
The lel and ler are the same base engine as the let just runs off a CAN ecu management. Lel is the 170bhp and ler is 200bhp. Same engine different map.
Can you please do a ler Vs leh please. I know ler has the let turbo let maf and let injectors. With a leh throttle body. I've noticed the ECU is at the back instead of the side. And I'm not 💯 but I think the ler also has the oil squatters. And same M32 gearbox but alot smaller of a clutch
Great video mate unreal knowledge on these cars and engines always watch your videos for advice and what to do, think you should do more off the show on the parts you replace and what you do to them for a more in-depth look on what you do to your cars
my astra gsi has a massive oil leak and its covering all the pipes in a oil type film, any ideas how to solve that? im going to be changing all gaskets and valve stem seals on the 11th June. i just need to know what would be best way to prevent any more oil leaks.
Hi, i'm going to buy an astra mk4 let this weekend, it's still at 200 hp but it has a leh turbo. What can i do to it to be stronger and allow more abuse? I dont want more hp but i want it to be safe to be abused. Many thanks in advance and nice video
mate you need to get that subframe sorted and make a video , i have a full front subframe & rear axel , polly bushed and powdercoated ready to fit on my GSI and need some guidance lol , i have a haynes manual but might as well be in Egyptian . great stuff great videos for us guys that want to learn - also the vxr brake upgrade is that a straight swap and does it make it heavy on the front end steering wise
Hi mate,I'm new to the z20let engine,I've watched a few of your videos,would you recommend victor reinz valve stem seals? I remember you said elring seals were to tight on the stem,help would be great please 😊😊
Just a quick one - if you or anyone reading this needs any Opel bits, whether it's badges or whole engines, I can help you out by sourcing in Poland and sending safely to the UK. Would love to see you do a Astra H TwinTop opc sometime 😁
Arron how hard is it to change wheel bearings mate my back ones have gone on my Corsa Vxr burg? And was wondering if you have a standard or any pre cat lying around thanks bud. Can I ask are you near Manchester way
@Aaron unknown I was just wondering I have an sri with the lel engine in it. Is it an easy job replacing this engine with the z20leh as in loom needed or would it fire up and drive with thw same loom and switching ecus?? Anyones help would be appreciated
Such great info. I have a 07 sri turbo. My mate who is a mechanic says its a ler engine, im so confused. Im rebuilding and forging it, safe for 20-25psi of boost?
Perfect timing Aaron, i am going VXR turbo on my LET at the end of the month, i spoke to Courtenay Sport regarding an oil restrictor and apparently the VXR turbos now have oil restriction built in and don't need extra restriction, they said if i fit one then it will damage the turbo mate?
By the way mate it is next to impossible to buy a z20leh oil pick up and girdle here , can you please see if this is something you can price up to send to Melbourne Australia . Thank you Aaron
Hi Aaron im rob and I'm in need of some help and looks like ur the man to talk to about the z20 engine me and a friend recently got a zafira gsi as non runner no compression on no3 the engine in the car was a z20let would it be possible to fit a z20leh engine in it ???? Hopefully u or someone can give me some advice tha ks rob
Is it possible to fit those on an 1.8 CSE? I have been struggling with my engine, I now have been looking for its Crankshaft all over South Africa. The engine is X18XE120Z45598. Please advise, and if you do have let's work on how I can get it for my car.
I love your videos and recantly had to rebuild the engine cause od 3rd piston. It just broke. I've got a k06 hibrid turbo with a 3" exhaust. What could have cause it in this case?
I know this is old comment but the answer is in your question. If you were running a K06 hybrid then I’m assuming you were running 300+ on standard Rods/Pistons. Z20let limit is rated to 280-300 max which means 260/270 is a nice safe spot, when engine is at its maximum limit its only a matter of time before something gives, yes forging is expensive but it may save you money in the long run
Pretty sure the black piston skirt coating is molybdenum disulfide, meant to reduce friction massively, its not Nikasil .. Nikasil is on aluminium cylinders to give the aluminium surface a hard plating to stop rings ripping them apart. Coming from the 2stroke mx bike world, when Nikasil plating chips off the cylinder walls and the piston ring grabs the bare aluminium they seize as they grip/dig the aluminium.
Great video. Great info also. Did you know that the generic toca engine used in the BTCC is loosely based on the the Vauxhall LEH. I think lol. Could be the LET. Started life as a Vauxhall engine!
Hi Aaron, Great videos, your knowledge is really refreshing to have someone who actually knows about what they are talking about! I have a question on the oil cooler. How does the thermostat work. With the water-oil cooler, would the thermostat not be open straight from cold to allow the oil to heat up faster? But if you had an oil-air cooler, you would want the thermostat to stay shut untill high oil temps, so you would need a different stat in the cooler? Regards Dave
Aaron or anyone else would I need my remap checked if I replace injectors ? still have the let ones and add a sport cat and a new fmic ? Thanks in advance
I would think so considering ecu is set to mix certain amount of air and fuel and i dont think a stock ecu could make adjustments that big but Im no expert 👍🏻 Edit: if there same size then definitely not.
the truth90 thanks for reply only big difference Is a 200 cell sport cat and a new intercooler car is tuned to stage 2 260bhp with pop and bang map by rabbid Iv also put a set of cleaned let injectors in Think it will be ok or will it need checked ?
Thoroughly enjoy your vids bud. Wealth of knowledge 🙌🏾 I'm in a situation where I can buy a complete Z20LET engine for less than I can rebuild my broken Z20LEH. Would I be at a disadvantage? Obviously I'll slap on my VXR turbo and the injectors. Would appreciate the advise
@@AaronUnknownPerformance i have seen cracked ones but i dont believe it is because of the material of pistons, but bad tune and very low piston to bore clearance, also bad gapped piston rings. Can you explain more of that?
Hello sir, I watch a lot of your videos and I am very delighted. I'm learning a lot but today I bought an Opel Astra VXR 2 liter turbo, I need help from you to fix a turbo pressure problem and have a diagram to connect the small hoses between my dump valve and intake especially since normally I should have a pressure of 1.2 bar and I only go up to 0.800 I must also check the tightness of my turbo boost circuit. if however seeing how passionate you may be could be of help. I would like to send you photos by exposing my problem on my Astra but on which site could we discuss? thank you for your precious time and your help cordially.
