Lets play: where are those fumes from!

Post by pilihp2 »

So, I've been dealing with a stank issue for a long while in the 5k.
I get exhaust or crankcase fumes in the cabin constantly.
If I'm cruising, windows up, A/C on, no fumes. If i come to a stop, it will then start to creep in from somewhere. It can be set to recirculate or fresh air and it will still creep in at a stop.
If I'm cruising with windows down fumes come in. If I'm cruising with windows up and sunroof popped up, fumes come in.

What the hell. I'm not sure if it's crankcase or exhaust. As far as I have seen/heard I don't have any exhaust leaks.
The mann provent can has a pressure relief at the top of it, if that pops open I'm guessing that crankcase fumes can then escape the engine out to atmosphere and can then be sucked into interior. But I'm just guessing at this point

Anybody else ever deal with annoying ass fumes? I get home from a drive in the car and my girlfriend will comment that I smell like exhaust. My friends have even mentioned it before.

I put a CarbonMonoxide sensor in the car just in case a while back, never goes above 0 so I'm good there :rofl:

Do you have cats on the car? If not, there you go. Shit stinks without them. I had one rigged up until I melted it on the virgin turn. The CCV could still be to blame, run a vent under the car, if it is venting in the engine bay it will usually come in the cab.

No cats, but it never ever smelled this bad on the 20vt which had a gutted cat.

I'll probably have to mess with venting some more I guess.

How's the firewall/heater air inlet seal to the hood?
