Hi, I'm posting this for a friend who has a '87 mustang 5.0.
He got his engine rebuild this winter. Everything is new except the block which has been bored 0,002 inch. The cam, crank, rings, pistons, rods, bearings etc...all that is brand new. He also has edelbrock aluminium heads and intake. He's running the engine on 5w30 mineral Quaker State. The cam is a Ford racing one, the crank is stock but has been balanced.
So the problem is that when he starts the car, sometimes bluish smoke (oil???) comes out from the exhaust. But it doesn't happen everytime. It also occurs when he accelerates kind of aggressively without being WOT.
The engine has approx. 160 miles on it since the rebuild, and the problem doesn't seem to decrease.
What could be the problem? He's being told that the engine could stop doing it, but as I said, it doesn't seem to go that way for now...
Any input will be appreciated! thanks.
