The car came with a timing chain and that was checked also. They discovered that the sprocket in the lower part of the engine was missing a tooth and that was immediately replaced even before we started checking out the sensors.
In setting the timing chain, they manually turned the engine a couple of times as they were adjusting the chain to ensure it was taut. I guess that is what the compression test is all about.
How can I tell that the timing marks line up?
From your explanation now I can confirm that they did not carry out a compression test. I am not so sure they even have such an equipment.
Is there any other way round it because I am almost certain they will not be able to carry out a compression test.
What is your advice on getting a fairly used engine of an earlier model that probably does not use a brain box but with adaptable engine seat?
