96 3.4 4Runner white smoke on start up
Having a problem with my 96 4Runner 3.4 w/215,000 miles. For the past 9 months the engine will skip for a few seconds on start up then smooth out and run fine. For the past 3 months it has been also puffing white smoke after an overnight or a warm start. I also noticed when coolant becomes low there is no skip or smoke and when I top it off it comes back. The head gasket is probably the culprit but is it possible that the coolant is leaking into the intake and then sucked into the combustion chamber. I have no overheating issues and engine runs fine otherwise. Any input is appreciated. Thanks

Sounds like a HG that is slowly giving up. What you describe are the symptoms I saw as mine was starting to go. Do some searching here.....there are some good HG threads.

Thanks for the input guys. I'll do a compression check, that sounds logical. I recently looked in the book and labor hours on replacing both head gaskets was 25.1 hours plus .5 hours w/AC. Does this sound right? That's alot of labor. Replacing just intake manifold gasket is only 3.5 hours which I may try. Why would it stop smoking when gallon low.
