Adapt the fitting to fit a compressor hose and fit it to glow plug hole. With engine on top dead centre for each cylinder being tested, pump some air into it. If it loses pressure, you should be able to tell where it's going. Into the sump would come out the crankcase breather hole.

mechanic's point of view

Any bent or stuck valve will give you bigger gaps like Nev said. Its hugely unlikely you've got crap under the shim or valve head and I can't see how changing the turbo would have caused it.
It must have always been like it, if its tight it will be why you have no compression, take the shim out and compression check the cylinder again (properly! ) but make sure there is plenty on lube on the cam lobe if you're going to spin it over just on the top of the bucket, and only do it once or twice.
I still think this is all 'by the by', and there is something wrong with what's been done to it doing the turbo or EGR, don't get too sidetracked by other stuff, double and triple check the turbo and EGR vacumm hoses and wires, even take it off again and put old one back on, as it worked with that one.

set the gap
Originally posted by NiftyNev View PostIf the valve was not closing you would have more clearance not less. Just set the gap and see what happens. Maybe you can just remove a shim? If it ran before then why has the valve adjustment changed so suddenly? Something may be broken somewhere?
