Oil Test Results
I have received the oil test results back and I have a problem, how bad not sure. Apparently there was coolant [potassium and sodium] in the oil sample that was sent to Blackstone. Looking through alot of threads it appears any number of things could be causing it. I am going to contact them tomorrow to try to find out the meaning of the numbers [minor to major] as I have not done this before. I am encouraged somewhat as their narrative indicated that once the leak is found my [PSD] "should recover nicely". Don't think it makes any difference for the test results but I did note on the form it was an IDI.
I've always been a fan of preventing a problem before it becomes a problem but failing that then at least minimizing the extent.
So if my thread reading has been accurate then the possibilities are:
1. Head gasket
2. Oil cooler
3. Cavitation
Any input to help determine where the problem lies is greatly appreciated.

IIRC the oil cooler will usually also get oil in the coolant and a little bit is pretty easy to detect as the oil will be on top.
Dave has posted the best way to test that isolates the cylinder that the leak is in. It involves removing the glow plug and used compressed air any bubbles in the radiator you have the offending cylinder. It will them be either a headgasket or cavitation in that cylinder.

I'll be watching the coolant as I flushed it before the oil test and it looks good right now. I'll also try to find the thread for the compressed air test. There is no detection of coolant in the exhaust and I don't think it's cavitation as I've been good w/ the DCA's over the years. Will doing a compression test reveal anything in the radiator regarding the bubbles you mention. Thanks.

The test goes like this remove a glow plug and pressurize the cylinder with air any leak should blow bubbles in your radiator. This only tells you which cylinder it is, not whether it is the head gasket or cavitation. Dave explains it better but maybe this will help.
