Hey all heres my probs, im kinda thinking the engines gonna need to come apart anyway, but its driving nuts what all this could be.
When i take off, i get a puff of blue out the back. Then if i slightly boost it (bout 5psi or more), more blue shit. But it will only do this sometimes, say i drive to work, it'll do it. Then when i drive home, no blue at any time at all.
Then sometimes when i crank the car over to start, i can hear it doesnt sound right, low comp on one cylinder, anyone can clearly hear it. But only sometimes when i crank it.
When i exit the car with the timer going, i can hear it missing out the exhaust. but only sometimes.
Did comp tests, came up with an even 155 give or take a couple. Engine HOT but this is when the cranking sounds fine and no miss. The engine has done 8,500 ks, forged acl pistons n rings. Valves were reground and new nissan stem seals used. Hi-flowed turbos done with the engine.
No oil in the cooler piping or breather pipes, running 18 with tuned PFC. How can these problems possibly be intermittent? and ive been watching out the back while im driving lately like a hawk to see. I havent changed anything at all, this has all started suddenly.
Soz for the novel, any insight would be good.
Cheers,
Mat.
