Exhaust Fumes In Cabin

[silverbullet94]

Hi guys,

This is my first post as I have just purchased a 94' series 1 GTsT, it currently has 400rwhp and is good for more (daily driver..).

There is a swirl tank in the boot (have dealt with fuel fumes), however the car is sucking exhaust fumes into the cabin from somewhere. I have pulled all the lining out of the boot to track down holes etc.. to plug up. I was wondering if anyone else has had this problem and could guide me to any known problem areas that let exhaust fumes into the boot?

Thanks.

I no with mine I have a catch can venting to the atmosphere an the fumes come through the firewall into the cabin.. Have you got a catch can?

I do have a oil catch can up behind the passanger side head light, I had a good look at the fire wall last night, but will check again. Thanks for the info.

My catch can is vented to atmo too up by the drivers headlight. I occasionally get oily smells in the cabin too.

You could possibly have an exhaust leak at the turbo/manifold.

I would assume with 400whp you have some sort of aftermarket tubro, or turbo/manifold setup. And as many people know the turbo bolts dont stay that tight for that long Unless of course you use those oval shaped lock bolt things.

Check that first. Make sure they are all nipped up tight. Try find a stock bolt locking thingy to throw on if you can too. It helped with mine, but after about 5 months the nuts managed to push past them too

I have a GT3582 R on a high high mount manifold, full custom exhaust etc... I will check over bolts tonight after work. Regarding the filter on the catch can, do you know if you can clean them by just using soapy water? I dont really want to spend $50 to get the K&N cleaner for such a small filter, better off just buying a new one...

Regards.

I soaked mine in petrol lol.

So yeah you can clean them with whatever you want.

Mate of mine with 240z had the same problem. Exhaust fumes getting sucked in through a faulty boot seal. Resealed it and all OK. Check ur seals with some chalk. Just a thought for an easy fix.

Hi guys,

Found the problem, the car has had a minor shunt from the passenger side so the boot does not seal correctly. Problem solved using some insulation I had laying around.

Thanks.
