hi guys i've been having problems with my 305 tpi . Recently my engine has been acting up for instance (i'm sure i spelled that wrong) when i turn my engine on my car starts puffing white smoke from the exhaust and it reeks of gasoline and i found that some semi dry gasoline at the end of my driver side manifold where the exhaust pipe connects to the manifold. I dont know where exactly its leaking gas. Prior to this added lucas injector cleaner about 2 weeks ago and it worked fine and i've done a recent tune up to the car about 1 month ago and changed the manifold gaskets, head gaskets, and injector O-rings. Also ive changed the charcoal canister and it still reeks like gasoline so i'm dumbfounded by this new problem my car is giving me so any answers would be appreciated thank you for your time.

 

white smoke, hows your coolant level? going down?, and check the color of your oil, if you changed o rings on injectors check for injector leaks, mine were leaking after i put new orings because i wasnt careful putting them back in.

 

Sounds like a coolant leak/ poped headgasket to me.

 

actually it was a blown head gasket thanks for the replies guys. But now engine got rebuilt and it wont even start. I've checked the plugs and wires but they are all connected right so right now i'm just lost i'll post a video of my car as soon as i can to see if you guys can help. Thanks

 

Have you tried spraying starting fluid in while trying to start it?

 

nope i havent i'll give it a try and see if it works

 

ok so when i was gonna us the starting fluid i noticed that there was fuel in the throttle body im suspecting a bad sensor or my egr valve isnt working anymore so what do you guys think it is?

 

Fuel PSI regulator could b bad.

 

Ok so I used starting fluid still no luck but, although all it does is pop

 

Well another guy it could be the fuel pressure diaphragm could be bad

 

Yeah thats what I was meaning. pull the vac line off and look 4 raw fuel.

 

Why are all these engines getting flooded with fuel lately?

If it did flood, then you spark plugs could've gotten wet, so you may need to either change them or pull them out and cook the tips with a propane torch to get the fuel out of the insulator.

 

New fuels, old rubber not designed for the crappy new fuel in the regulators?

 

You think they're going over 10% Ethanol now?

 

Who knows, could just be old parts reaching the end of the line?

 

Hey my 91 z28 with a 305 idles high and has no ***** off the line, what the hell could be causing this car to be such a dog? I've done a complete tune up, ported plenum, K&N air filter, 1.6 RR's, High flow cat and flowmaster exhaust. timing set at 6*, tried bumping but didn't do nothing, trans was rebuilt 2k miles ago, I'm changing the rear from the crap 2:73 to 3:42 or 3:73 as I type this.

I've owned a few of these cars and so far this one just sucks no matter what I do to it, I thought speed density was a good setup?
