94 pickup with 3.0 v6 blowing white smoke

bowhunter34 · 11-01-2009, 06:20 PM

A few months ago i was driving my truck and i relized that it started blowing tons of white smoke. Enough to cover the road. I started to see my temp. go up and immediatly turned of my truck. Tore it all apart and replaced all the gaskets from the heads up. Also got heads cleaned, shaved, and pressure tested. Put in all back together. Started it up and after a min of running it, it started blowing white smoke. Let it run and it got worst. kept looking at radiator resourvour and it didnt look like it was loosing water. After 5min i looked down by the intake mani and saw water bubbling out. Turned it off and tightened the bolts. Ran it for atleast min then it started blowing white smoke. We only had it running for about 5 min then turned it off. Right now i have the intake mani off thinking thats the problem. Gaskets look good and there brand new. Any tips or ideas of what could be causing this problem? Thanks

I can't answer the question, but you'd probably have better luck if you post the same question over on the 86-95 trucks section: http://www.yotatech.com/f116/

I did think of something to check. Make sure you reconnected the little hoses that run coolant through the throttle body back up to the throttle body. I think I remember one guy that connected that coolant line up as a vac line which pours coolant straight into the intake.

that'd do it!!!! also possible intake gasket leak or possible bad hg install? not trying to insult, but it's always possible

Thanks.
Im not worried about the hg because we scraped and cleaned the heads and the top of the block like no tomarrow. We also got new head bolts and followed the hynes book toruqe specs. We also have the vacuum hose diagram so were gonna follow that. I was reading some other posts and im thinking i didnt burn all of the collant off. We probable only let it run maybe 10 min. So were gonna put everything back together and let it run 20 min or more. Also when it was blowing white smoke the coolant level never went down. But this is my first hg job so im still learning. Thanks for all your help.
