When to visit my car for the first time in 2 months. Battery was dead, anyways managed to get into it and attached another battery to it. First turn and it started , whey i thought. The carb is dechoked and has also had the choke spindle removed, so had to rev it to 2000 revs just for a minute, then it idled perfectly on its own round the 900 mark. At startup the oil pressure is 45 psi. This is constant untill the engine has warmed up untill the fan kicks in and goes down to 40 while the fan is on. Left idleing for another 20 mins the pressure stays at a constant 25 psi down to 20 when the fan kicks in. It then doesn't drop any more. This engine has had new oil pump internals, new shells, new pistons, liners and rings. Everything has been chemicaly cleaned and had all new seals and a head skim and pressure test. Head is 72.5mm. This engine has done 60 miles before headgasket popped , due to fueling or badly fitted headgasket, not sure which. New headgasket was put on and its just been sat for 4 months, every now and then i start it up and it just idles for 40 mins. Also a bit of oil seems to come out of the exhaust mixed with condensation, but this could well be from the headgasket popping last time. What do you reckon guys?
