| OK...here's my story, as I did have the same problem....cracked block...coolant got in the oil..wiped out my main bearings...but the white smoke was from oil mixed with coolant running down the valve guides after I shut the engine off. Next time I started it, quite a bit of white smoke when it first started up and thereafter when I would accelerate, though a second acceleration run immediately after would be less noticeable for some unexplained reason. Anyway, a intake manifold or head gasket leak could do the same thing. Intake manifold leaks are pretty common, as a V-8 is sort of a poor design in having 4 main pieces bolt together in a diamond like shape relying on gaskets to keep coolant passages tight when the whole thing suffers from repetative expansion and contraction from thermal heating and cooling. I suspect changing the intake gaskets and using contact cement or gasket shellac around the collant passages might cure the problem. One of those pumps that fasten in place of the rad cap to check the system under pressure might reveal something...maybe. Recheck the torgue of the mainfold head bolts is a good idea, though overtorquing to cure a leak is not recommended. If the machine shop planed the heads, the intake might not fit quite right no matter how good the gasket inbetween is, and leaks will undoubtedly occur. |
