And the oil dip stick probed for crude!
Well, a swap could be the thing but unfortunately there are no omegas around as far as i know.
They were very expensive at the time. I've occasionally saw 2 or 3 V6 2.6 never a 3.0.

I need a compression gauge from ebay/amazon, any recommended brand?

it doesn't really matter, unless you're going to be using it every day. One with a rigid extension to fit down the spark plug tube will be easier to use.


If you have an air compressor, then a leak-down tester is much more useful

I don't see how I can do a proper leak down test with cold engine

It is a all relative hot or cold, so if you compare the cylinders, if one is way down on the others then you know there's a problem with that one.  With 6 to measure you should get a good average reading and it will be pretty obvious.

That's theoretically true for all of the tests. If taking readings then you're looking for differences between cylinders, and changes between tests.  That's how you use leakdown testers to track engine deterioration against time. This is SOP for race and aircraft engines.


If using pressure to create/diagnose leaks on a stationary engine, it helps if the engine is up to temperature. But it isn't essential.
