1995 inline six intermittent white smoke
1995 f150 inline six
almost 200,000 miles
just replaced the head gasket
did valve job
replaced oil pump
cleaned thottle body
replaced pvc valve
i'm sure i'm forgeting some stuff.
a little background on the problem:
after we bought the truck we started to change the oil only to find that there was none showing on the dipstick. i know.
we changed the filter and added oil. upon starting the first time after the oil change, tons of white smoke poured from the tail pipe and it began to run rough, also lit "check engine" light.
After we took the engine apart we found that the old oil was gelled up very badly. packed into the valve covers and various other places.
evidently the previous owner was not big on changing oil. we figured that the gel in the engine was not showing on the dipstick and therefore when we added the new oil it was considerably over-filled.
at that point we cleaned everything, did the maintenance listed above, and put it back together. when we fired it up, it ran a little choppy but no smoke.
after a few minutes the smoke was pouring out of the tailpipe again and "check engine" light.
I checked the codes and found the MAP sensor was failing as well as a few other problems, including engine idle control. After figuring out we left the MAP sensor unplugged, and plugging it back in, it ran a little choopy but no smoke. we started it a few times after that, let it warm up, and it ran fine.
I just took it out for a test drive and it ran good. i gave it some gas from a dead stop. it spun the tires, but the smoke from the tailpipe came back.
I parked it for about an hour, cranked it over, and no smoke, no check engine light, and it was idleing better.
Any ideas or similar issues?
Thanks!
