I have a 92 SSEI and somethings really wrong. Whenever the car is cool and runs fine but blows a little white smoke out the exhaust. Whenever the car heats up it runs real rough and blows alot of white smole out the exhaust. The car got up to 240* F today when I shut it off.

What are some things that I should look for. If I run a compression check will that tell me which one is blown?

Any tips or hints would be great..

If your head gaskets are actually bad, I'll buy them for you.

It'* your lower intake manifold gaskets, and if you don't take care of it very soon, it'll cost you your motor when the coolant/water mixes with the oil.

Drain your oil right now, and begin teardown.

The oil looks good, its not white and doesnt smell burnt.

Because FOR NOW, you're ingesting it into the cylinders where it'* burning. Exhaust smell sweet?

FYI, we have yet to see a member here in over 4 years with a certified head gasket failure. EVER.

I might have had one but I never tore it down so we will never know. It was a sudden failure, meaning the engine died in one day completly to the point of running good and then dead..blowing steam like crazy....remember the video?

I've learned a lot since then..my car looked like this:

Look like yours?

(videos are down right now...I need to reupload)


As you can see, in the video the exhaust is exiting out of the front of the engine bay, near the heads, this lead me to believe cracked head or gasket. actually it appears the exhaust manifolds were cracked.

It has good oil pressure. How else would I tell if its the lower intake manifold gasket. Is there any kind of test I can do to be sure.


HANS: the links are broken, no, exhaust is exiting in the rear. Engine looks normal . My temp gauge did look like that.

that means your manifolds are not cracked...thats a good sign.

You need to replace the gaskets though.

On my current 93 SSEi They have been replaced twice due to the exact same failure you are looking at, same symtoms.

Twice in 100,000.


I forget if the SC gasket is required to change as well, but at least the LIM gaskets, and the TB gasket

Can I pulll the SC and LIM off as one and replace the gasket that way. Wheres the cheap place to get the gasket. The car has 140,xxx on it. When I get to the LIM gasket will I be able to see where it failed at.

If I do a compression check on the cylinders, what should it read?

The SC and LIM do not come off as one piece. You will need all the gaskets.

Compression test depends. Ensure you are performing the test properly by removing all plugs. (don't mix up the firing order).

Wet or dry?
