ive just fitted a heads to my tt as it had bent valves

i replace it with a head for a mates car using my cams and lifters

so away i did a compresson test and only had 30psi did it again and got it up tp 60psi what going on all of the ofter side have 150psi

dose all the oil pipes from that side have anythung to do with

Did you make sure both mating surfaces were clean and smooth? Also what head gasket did you use? Was the doner head pressure tested before fitting?

i guess it wasn't that important.

also, were the heads skimmed before fitting ?

just tryed it today and it 130 psi

just tryed it today and it 130 psi

 

Thats still not great bud.

Were all 3 banks of cylinders the same and was that at normal operating temp?

Is thecam timing correct?

Could be that the lifters are slightly jacked out and need time to settle...

well we'll see monday as they had all weekend to settle and as i cant run the engine they are cold just turn it over.
