You are probably just burning out 10 yrs of accumulated whatever in the exhaust system... I bet after 100 miles the smoke is gone...

Sitting 10 years? I'd change the timing belts right away BEFORE doing the 100 miles...

Ditto on the timing belts... run some fuel injector cleaner through it for a few tanks - will help as well..everything needs to loosen up and bed itself back in again.

I have changed belts and tensioners plugs etc and have done about 300 miles and it has used around 4 litres of oil as well and no visual leaked the exhaust tail pipes have oil in them

Wow, 4 liters of oil in 300 miles and no visible drips, there shouldn't be a single mosquito left in the UK! :o :lol:

.... Just "thinking out loud" here...

Check spark plugs, after 300 miles of burning that much oil I would expect the plugs for the cylinders burning oil to be completely fouled. This may give a clue which cylinders are having a problem. This would be the case if oil was burned in the cylinders.

However, you say it starts smoking AFTER being warmed up 10 mins. If oil was being burned in the cylinders it would smoke immediately when started. The only way I can think of for oil to get into the exhaust pipes without being burned in the cylinders would be thru the exhaust valve seals.

As to the oil restrictor in the head, it has two o-rings on it, and is sandwiched between the head and engine block. even if the o-rings were bad, oil would have to work its way thru the head gasket and would more likely end up in coolant passages. In order for oil to reach the combustion chamber it would have to get thru the steel crush rings on the head gasket at the cylinder bores, and you'd likely be leaking between the water passages and combustion chamber too and burning antifreeze in addition to oil. And since you have good compression, I tend to rule out problem with head gasket.

Check spark plugs and report back. 4 litres of oil in 300 mi? That's an awful lot... Never heard of that much oil getting past valve seals.... Hmmmm.... :roll: If the sparkplugs are reasonably clean it would almost have to be valve seals.... Hmmm.....

190 psi compression is too high. On a new engine the compression should be 172 psi. On a good engine with some miles on it you can expect around 165 psi. Most likely you have excessive carbon build up in the combustion chambers. (If your test was done properly).

All 4 plugs are black I have replaced stem seals maybe it is stuck oil control rings maybe could pour something in bores to soak them n try and unstick ?
