Hey guys, just need some kind of guidance here, So long story short bought a 32 gtr roller. Friend of mine had a motor 26dett that had been sitting around for abit but said ran ok. Gave him a carton of beer and took the motor home and dropped it in. Started up great, no smoke all fine etc just made sure everything worked. Idles smooth revs up smooth gets up to temp etc etcTurned off. Cooled down and did compression check, dry test. 150psi on clyinder 1,2 and 3 cylinder 4 145psi Cylinder 5 plug was abit wet and smelt of fuel was 90psiCylinder 6 plug was wet and smelt of fuel and was 70psiSo obviously problem at back two cylinders. Need to get a leak down test done but anyone got any ideas?? Headgasket? It really idles and drives fine loke there is no problem?
