I need a vacation...
I've got a slanty in my 1965 crew cab truck that smokes. Yeah I know, it's not an A-body, but my '65 Valiant slanty is doing just fine.
Here's the basics; 1980 engine, supposed ran good when pulled from previous vehicle. Installed in the crew cab, pissed water out of #1 exhaust port when I finally fired it up, had cracked head and bad timing chain components. Unsure of how long it had been since the engine was last run. Had extra head that was sent to machine shop for valve job and to be resurfaced, milled .050 in. Installed "new" head on engine, also installed Offenhauser manifold and Holley carb. Runs great, except for the smoke. Have run the engine about an hour or so. About 30 minutes with cracked head and about 30 minutes with new head.
Begins to lightly produce oil smoke 4 minutes into a cold start, then seems to progressively get a little worse. If I stab the throttle it'll smoke more and settle back down at idle.
I've noticed that the oil, which was fresh, is now black and thin, and shows very high on the dipstick. Cant' tell if it smell like fuel though, but I suspect it may. I'm thinking that the fuel pump diaphram is allowing fuel to get into the crankcase.
My question is this; would thinned out oil that has fuel in it cause this same type of smoking? There does seem to be some blow by thru the valve cover, but I'm not feeling any internal pressure out of the dipstick tube.
I'm going to get a new fuel pump tomorrow, and change the oil of course. Hopefully that's going to be the smoking issue, but I dunno. Any ideas guys? AND gals too....
