How do you know that your gauge is accurate? As someone said previously, the test you're doing is just looking for consistency between cylinders.

Mechanical pressure gauges are notorious for their inaccuracies, so I really wouldn't trust it.

As I said, the best way to measure the clearance is to make sure that the heel of the cam is towards the valve (i.e. the lobe pointing away from it). Then, that will give you a true maximum clearance and also repeatability.

I replaced the last few shims that were under today and then had a thought. I seem to have over torqued the cam shaft holder bolts. After consulting Haynes I found that they should only be 10Nm. It seems that it makes all the difference. all my clearances are now comfortably in the stated range.

I'll finish rebuilding the engine tomorrow and will then continue the search for a garage that will measurethe emissions and let me adjust them.

just measure that all the cil are the same..

Tks

Thanks Tks. A bit of reassurance is nice. It does start very quickly which is a good thing. I took it out for a few laps of my local dual carriageway today to burn off all the oil and generally bed the engine in a bit more. It does seem to pull a bit better now than it did.

I also revved it quite a bit to clear out any deposits that may be worsening the emissions. Even though the road in question is 1/2 mile from the houses, my wife said she could still hear it.

I found a bit of frost on an island where the sun hadn't got to it Boy was the wind cold today.
