0 oil pressure = what long term problems

[kimper007]

I have a 90 talon awd with 573WHP. Last weekend the nut/bolt that my oil filter screws onto decided to back out of the oil filter housing and piss all my oil out. I noticed this when my car started to run a little funny so I started looking at my gauges and noticed zero PSI oil pressure. Like everyone in this sistuation my heart stopped so I pulled over and shut it off, luckily I was only going 5MPH at the time. My question is after fixing the problem and draining what ever oil was left over and putting new oil in, what are the chances my tentioner fails. I started it after putting in new oil and it ran a little ruff but it had 80psi of oil pressure. I let it run for about 5 minutes and everything seemed to smooth out but I am curious about long term. Should I change my tentioner and belt while I am a head or just ride them out??

i would be more concerned with rod and main bearings being possibly trashed due to oil starvation

The timing tensioner on these engines is a separate unit. It doesn't rely on oil pressure from the engine (like older Nissan inline 4 cylinders do) so I wouldn't worry about that. My main concern be the bearings in the engine and the cam journals. If you don't hear any obvious knocking from the engine you might have dodged a bullet in the bottom end. The overall longevity might have been reduced, but guessing how much would just be a shot in the dark. It still wouldn't be a bad idea to pull the pan and check the rods for vertical play. I would also pull the valve cover and pull a couple cam caps to check for gouges or heat marks on the cam journals and cams themselves. If you still have the old oil, run a magnet through it and see how much (if any) metal collects on the magnet. This should give you a decent idea of how much damage was done.

Even though you have a 90 you might find this interesting about the stock oil filter mounting: Randy Nuckels

Never could figure out why Mitsu abandoned the air oil cooler (like mine has) to the heat exchanger type....

Mits did that because of the two way street with oil temperature..shouldnt be too cold or too hot...the water to oil cooler helps raise oil temp for longevity of the engine etc...
