Somehow, I was so busy and didn't get chance to redo the diagnios on my truck. I had posted the issue on my truck. Armed with new oil pressure gauge, I pulled ICP out and put the oil pressure gauge in the ICP's hole. I changed the oil. The oil was ruined with brake fiuld that I accidently poured in the engine. I drained and left it draining all the day. The oil stopped dripping, leaving strange gummy oil - bad oil or that was result of adding brake fuild to the engine oil? I just hope that 1/2 cup of brake fuild doesn't have much effect on the engine. Anyway, I recharged the batteries since the truck wasn't started over 2 months. The engine started on first try, which is good news. I watched the high oil pressure gauge as I rev'd the engine. I recorded the results.

The results:

600 rpm - 600~650 PSI <--- idling speed
1000 rpm - 650~700 PSI
1500 rpm - 700 PSI steady
2000 rpm - 800 PSI steady
2500 rpm - 1100~1250 PSI (tried to keep engine reving steady)
3000 rpm - 1400 PSI (able to hold the engine reving steady)

Are the results good? The ICP is out of the engine and sitting on the work bench in my garage. Pretty much that it tells you that ICP isn't plugged in the system. Do I need to retest this with ICP out but plugged in the system? Let me know which part is the guilty party.
