95 4.3l W having serious issues, need help
Hey guys,
I got some great advice last time I posted regarding my EGR valve so I'm hoping to have the same results. This morning when I cranked my truck the idle was incredibly rough. I immediately suspected the EGR. I went to get some gas and had almost NO power and a lot of "puttering" out of the tail pipe. So I come home, take off the EGR valve and clean it. It wasn't dirty. Get everything back together and I'm having the same result. Symptoms are: LOTS of white smoke coming out the back with a VERY heavy smell of fuel. A short test ride resulted in me using about a 1/4 tank of gas. I checked my Throttle body and found it moist inside. I'm not mechanically savy so any help will be appreciated. I have a feeling this is a bad one.

check the PVC valve. It's a little 1 way valve that goes on the valve cover, with a hose going up to the air filter assembly.
If you can hear a ball shacing around in there it's probably good. But still blow on it from both sides, it should seal one way but not the other

Well, I checked the PVC valve and it appears to be fine.
On a hunch of a blown head gasket, I also checked my radiator fluid levels. That also appeared to be fine. I'm going to try to run the truck for a couple of mintues tonight to see if any other symptoms jump out. I did notice a damp spot under the exhaust on the ground that appeared to smell like fuel. But that could have been the fact that I had just generated 40,000 cubic ft of smoke that also smelled like fuel. Any other ideas?

Yeah, with the gas smell, you could be dumping fuel... Drop about a cup of oil and see if it smells like gas..

I'll be sure to check those things guys. Appreciate the lead.
What would I be looking at as far as repair costs...hypothetically?
