Hey Mr. DJ.....
Post your question to the w-t_audifans group on Yahoo - that's the West
Toronto Audifans group, there's quite a few folks there with their own fave
mechanics they can direct you to.
Compression tests are not hard to do, but make sure you start with a fully
charged battery and a warm car and ground the removed plug to avoid ignition
damage. The test will tell you if there's a pressure leak in the cylinder -
whether through the valves, around the rings or a blown head gasket. A
leakdown test is a good thing to do in conjunction with the comp. test - it
helps to narrow down the problem (if there is one). HOWEVER - the
compression test will not tell you how much the turbo is compressing the air
into the engine - the turbo does very little, if anything (maybe even
somewhat of a hinderance), as the engine is being turned over.
Have you had the codes pulled from the ECU? what do they say is wrong?
Do you have a K&N filter in there? If so, chances are your MAF sensor is
burned.
Was the car equipped with the oft-malfunctioning coil packs? - That might be
covered by a recall.
Why do you think the turbo is blown? Is it noisy? Does it have lots of
play in the bearings? Is there metal filings in the cat from the turbine
vanes grinding against the housing? Is the turbo siezed, or the shaft
busted?
Cheers!
