Low Oil Pressure

[toffy]

well for starters, if the oil pressure problem is caused by a lean out then its too late for the motor so go and get a compression test. It sounds to me like your guage is playing up (i.e not reading right), your rough idle would be from the 040 and the fuel smell would be because skylines have what is basically a cold start choke (adds more fuel until its upto operating temperature). hope that helps

^^yeh i hope ur right with the cold start thing, i have heard that there is something like that but im pretty sure i didnt smell it until recently.

with the running lean thing, i have nfi whether thats the problem. i still have my money on it being a oil pump. but there are many characteristics that dont seem to lead to being oil pump, if anything they lead to not having enough oil, but like i said i have checked the dip stick and it seems all fine.

ok so more info:

when i secure the dipstick tightly the issue doesnt seem to be bad, when i sit it on there loose it comes back. i assume this is what its like all the time as after driving it slowly comes out a bit and sits loosely. also revs drop and rise simultaneously with pulling the dipstick in and out.

so its looking like a bit of crankcase pressure, but i dont seem to be burning any oil, so i dont know about rings. i also made 141kw's recently with just 3inch catback, pod (un-heat shielded) and chinese copy FMIC (unboosted, so no real gains yet) with the above A:F's, so it doesnt really seem like my engine is in all too bad condition, still seems to pull pretty hard throughout the rev range, possible a bit more vibrations (or it could be in my head) but that would make sense with low oil pressure.

bump, cos i need to know badly
