I just did the LIM gasket in my 2000 SSEi 115k+ miles. My hot oil pressure at idle in drive (500-600 rpm) is roughly 20-25 psi. At idle in park (800 rpm) roughly 30-35, maybe in the high 20'* sometimes. It has yet to dip below 20 psi. I feel this is low, before I noticed I was losing coolant and I replaced the LIM, I felt My hot idle was 30-35 drive idle and 40 park idle. This is concerning because I know of the possibility I could have ailing bearings If i had coolant i my oil ( It didn't seem like there was, seemed it was mostly resting on the block, but was hard to tell) Is this something I should be concerned about ? Thanks.

20-25 is low even for a 115K engine. Did you do an oil change after the intake job? If not, I highly suggest you do get it done.

Yes I changed it, twice.

Hmm, then it does seem you may have some bearing clearance issues. Maybe because of coolant oil mix. You can try and upgrade your oil to 10W30 to boost the pressure some.

But, be forewarned, your engine is on her way out.
