Siena:
For starters, the questions you're asking here can't really get answers with any degree of accuracy.

I see someone asked you to take a picture of the engine, and post it here. You haven't done that. You are asking how to check cylinder compression. Well, I've got news for you. Checking the cylinder compression in a diesel engine is very different from doing the same in a gasoline engine. Different tools, different approach, not a DIY job either.

You don't even know the engine code, or spec. So what would you compare your compression test results with, assuming you were able to do it?

You're talking about buying rings "first", then trying things out. That is the best way to chuck money away. You might as well put a bunch of Naira notes into a blast furnace, and watch them burn. If you're having new rings fitted, you can't just "buy a set". The engine will first need to be stripped, the bores checked, and bored out to the next oversize if they are damaged. This will mean either new oversize pistons and rings, or if a very slight increase in bore size, matched rings with your existing pistons. You can't simply guess what is needed.

Putting new rings in will also require a full gasket set, and new cylinder head bolts. You can NOT reuse the old ones, as they are stretch bolts. The cylinder head gasket also comes in 3 different thicknesses, depending on how much the head has been skimmed by, assuming it's been apart and worked on in the past.

Take your LT to a shop that know what they're dong. Otherwise you might as well scrap it / sell it for spare parts.

Good luck.

Pls, Siena or any other person that can help,
I need your help to have a full details about the Golf 3 with this engine number: ENGINE: ZE161363.

I have a VW LT 28 Diesel engine with turbo, have been searching for a thread /forum of people using the same range of bus,pls lets this issues on these buses here. Thanks

Currently am battling with low acceleration problem, have changed d filters, still same, i later learnt its d injectors.I wil fix dat today

GuiltySpark343:


Low acceleration is caused by low compresion ratio, now since your mechanic doesnot know that change him

emperoracro:
Found d problem, there was a piece of paper in the tank that was preventing gas flow

Siena:

Gas flow in a DIESEL engine?
