As long as the valves are closed on each cylinder that should be ok,hardly much extra work to time it up after all that.but I cant for the life of me believe you cant spot something obvious that's making it run that low compression! Generally that low is no valve/hole in piston!
Absolutly nothing mate that's why it's thrown me, there is no play In the pistons, the bore have no marks on them, the valves are all in tact and hold petrol in the chamber.Originally Posted by Andy
its baffling that's why I was blaming the gasket and bolts as they had tech been used more than once
You could bolt the head down with no cam fitted to keep the valves shut but you will write off a head gasket and maybe a set of bolts if you feel anally retentive
Tbh Stuart I was thinking of building it back with the gasket and bolts that I took out to try to replicate the engine before a stripped it
Were the head bolt holes in the block cleaned out properly before you fitted the head?
No Tom they weren't would that cause a problem
Its unlikely as it would have ran crap to start with
170psi loss is massive.It has to be going somewhere big.
Valves open and close ok?
what's the point? clearly something is wrong, and whatever it is the head will likely need to be off to fix it.
This is just to carry out a leak down test not to actually run the engine
