Normal driving, I see no smoke. However, when I lay into it I see white/greyish smoke. The engine has 182k, and I was going to upgrade the heads to AFR 165. Is this an indication for me to rebuild the shortblock or is it normal for high milage engine.
i dont know about the smoke, but if you are going through the work for heads, I would rebuild at that mileage and if you have the extra cash might as well get it bored out to a 306.
What condition is the pcv system in? This can throw some oil into the intake manifold, which burns and blows smoke.
Peak down the oil filler neck and verify that the oil baffle has not been removed. If you see the rockers then the baffle has been ditched, and it is time to put it back in.
Remove the pcv to intake hose (wherever is easiest), and check for oil in the line. If the inside of the hose is wet with oil then you will know oil is getting into the intake that way.
my vert was doing that recently and found an odd problem.my dipstick was in upside down and it was pushing oilspray out of dipstick under hard acceleration.flipped it over to where the dipstick clicked and no more problem
yeah i know, i had never heard of such a thing and a fellow stanger that i hold in high regaurds pulled my dipstick out turned it over put it back in and looked at me like i was stupid........guess what. no more oil spray
I guess I'm a bit thick. Are we talking smoke from the engine, itself, or smoke coming out of the exhaust? If it's from the engine bay area, could be that valve cover gaskets might be blown, or getting too much crankcase pressure in there for whatever reason (bad PCV valve, too much blowby, or something plugged up?), and thereby spewing oil onto the exhaust manifolds/headers. Otherwise (if it's out the exhaust), I'd wager on bad piston rings and/or valve seals.
