Compression Test Results!

That isn't a typo.  I'll buy a gallon jug of oil, put in about oil everyday, and pretty much I need to buy another gallon jug by the end of the week.  At about $12-13 for a one gallon of oil, the price of driving this diesel is not cost effective.

Very true.  The gulf isn't that great on MPG anymore, especially with the cost of diesel, and fuel additives, and.. oil.. heh..
You have to love these things, you can get about as good economy out of any number of cheap gas cars when all is said and done.
But as I was saying the other day to my little lady as we were driving behind a geo metro, would you rather drive that, or this?(my caddy).
So, yeah..

I'm still betting worn vavle guides/seals/valves.

Well, I redid my compression test again from right to left at normal operating temperature, with a battery charger hooked, here are the corrected results:
1)500psi
2)480psi
3)440psi
4)460psi

What do you all think where the oil burning is coming from?

its either blow by or valve related. the oil is getting completely burned, whitch makes me think the engine is getting it from the intake side somewhere. put a different head on it if you have one laying around.

the oil control rings could be worn out and yet the compression rings could be still working good...

another thing to look at is the common problem with the 1.6 blocks, being that blowby shoots into the sump making the dipstick shoot out. i can almost bet that if you vent the sump somehow, you will see a moderate to large decrease in oil consumption.
