2000 SW2
Default SW2 number 1 cylinder wet - Head gasket or Intake Manifold gasket?

Hi all,

As a newcomer to this forum, I'm very impressed with the quality and amount of good information you provide - many thanks for that!

I just purchased a 2000 SW2 with 82K miles, drove it home (28 miles) and discovered, when changing the plugs, that the number 1 cylinder is wet with coolant. The car does not smoke, the coolant temperature and appearance is normal, no service lights, and the only thing I can detect is a little hesitation when accelerating from idle and a slight coolant smell under the hood. Also, don't see any oil on coolant reservoir and the oil on the dipstick looks normal.

My questions are:
If a compression test on number 1 cylinder comes clean, is it safe to conclude the problem is the intake manifold or intake manifold gasket? Is there any other route for the coolant to get in?

If the culprit is the intake manifold, is there any possibility of replacing it, or its gasket, by just taking the bolts out, dislodging the old one out and positioning the new one in without taking the whole thing apart? What about trying to tightening the bolts?

Also, about the compression test, Is there any extender I can get to reach the deep well threads?

Thanks, John

REWARD EXCELLENCE!

My compression tester actually has a quick disconnect on it. However to test on a Saturn, the only way to do it is to use the end that you have to hold in yourself. I've been thinking about building my own leakdown tester. There are instructions here. Except I'd use a piece of straight pip instead of the hose. That way I could use for both compression and leakdown tests.

...
There is nothing more frightening than ignorance in action.

REWARD EXCELLENCE!

BarnOwl,

Thanks for the link. I decided I'll make my compression tester hose rigid by inserting it in a metal tube and fill the tube with epoxy. In that way I'm not messing with the total volume seen by the meter.
I still would love to get some answers to my other questions - guess I should rephrase the thread with a HELP! kind of title...

Thanks, John

Just an update on my problem.

I flushed the coolant and replaced it adding 2 Saturn sealer (ginger) tablets (1 crushed and one whole). No more leaks.

If compression was ok, my bet would be the IM gasket.
That sealant might last forever or it might be a short term fix.
I hope the leak doesn't come back. I hate coolant leaks.
