Its been getting worse, I only drive it about once a week, and have been hesitant since I have been smelling this. I dont wanna rule out the pulsation dampener, but wouldn't that cause a fuel smell at all times. I can be cruisin or drivin without hittin boost and not smell and gas smell at all, but once i get even 1 psi it smells

 

There are MANY threads on problems like that. Here's one to get your started:

Have you replaced the large hose going to the brake booster? It has a one-way valve embedded in it that, if missing or failed, will produce this symptom.

 

thank you... also i PM'ed you

 

your primary or secondary ijector o ring can be damaged, if u can even smell it under boost below 2800 rpm then its most likely teh primary ones, if its at higher rpms its prolly teh secondaries, how old is teh motor??

 

~25K, are those replaced with a new engine?

 

u shouldnt have teh injector problem with a new engine, if they are replaced, if the guy knew what he was doing he shoudl ahve replaced them, did u pay for it?

 

hmmm, dont think I have messed with the hose to the brake booster, although when i converted to a 5 spd I had the whole thing pretty much torn apart... ill take a look in that area...

 

eh, the guy that replaced the engine was an idiot... and i didn't know anything about the car at the time, I have had to fix a lot of his mistakes. So there is a good chance he didn't do anything with the injectors....

I bought the car after immediately after the engine was replaced, from the mechanic that replaced it...

 

OK, once again. Fuel ONLY UNDER BOOST usually means the aluminum check valve that runs between the UIM and the Purge Control solenoid Valve is broke & is allowing boost to pressurize the charcoal canister.

If you search back you'll see prev. posts about this. It's right in front of the UIM & is visible once the pressure tank is pulled.

Luck.

So what does it mean when there is alot of gas in the Intercooler piping? My buddys car isnt running right now and there is alot of gas smell in the oil left in the IC piping.

 

your secondaries might be leaking. could be from the valve body, o-ring, fuel rail gasket. it could also be one of the many other things pointed out. you gotta get it looked at by a shop experienced w/ fd's.

 

but does that stuff cause gas in the IC piping? I just cant see why it would smeell like fuel in his IC piping. And his car wont run.
