Exhaust smell in cabin

[yanky84]

Hey there,

I am pretty new to cars, but I recently bought an 1989 Toyota HJ75 Troop Carrier.
And I really would like to invest some "love" into it
The preowner were total idiots just chewing down kms without doing anything to it.

My worst problem is the exhaust smell, while driving. I guess it comes through the window, only smell it when it is open.

I checked the exhaust pipes, but couldnt find anything.

Could it be caused by anything else? Oil burning of some hot parts, etc?

Any hints what to check?

Another thing: the electrics, is there anywhere a cable layout to get? There appears to be some custom wiring I cant quite figure out.

Thanks in advance, Dennis.

Welcome to the forum! and congrats on your new ride. My Cruiser has the same problem, exhuast smell in cab. I narrowed mine down to my exhaust manifold/gasket. Pop the hood and play with the throttle cable and see if it puffs smoke out the exhaust side of the engine.

Thanks for the hint, I will check it out.

What did you do to fix it? Just replace the gasket? Is it hard/expensive to do?

There is also a cabin fresh air intake line off the air filter (at least on my HJ61) and it can get unseated easily. Happened to me and I got sick from the fumes coming in! slept for two days before I could go and open the hood to look!

Whoa, I didn't even see this reply until now. The gasket cost $35 dollars. I had to disconnect the exhuast, air cleaner assembly and exhuast manifold. Turned out I had two broken studs and my gasket was burnt to nothing. Along with the cost of a very hard to find tap to re-thread the holes, and new studs, and paying 4 wheel to drill out my busted studs, it was about $250. If all it is is a gasket, and you have the tools and don't have to do any drilling, it should only cost about $40.
