Oil light comes on for a second randomly

[Terrorizer]

Is there a specific noise that bad rod bearings will make? I realize the only way to really know is to drop the oil pan and physically check them, and I will eventually do that when I have the time. But in the mean time I'd like to know if there is something I should be listening for.

If you have a very slight knock when driving and when you let up and coast the knock goes away. On my '93 this was a bearing broken in half.

When I spun a rod bearing, I heard a slight tapping on engine deceleration (using the engine to slow the car down). This tapping happened non stop for about 500 miles. I thought it was a valve out of spec until one day when I hit it in 3rd. Blew the engine.

I replaced my rod bearings at 94K. My engine started to knock. I think my problem was that rods at 3 and 4 starved for oil. When I removed those bearing they were down to the copper and smelled like burnt oil. Replaced all the bearing and 55k miles later all ok.

I don't understnd how people have bearing issues with these cars under 150k or so.. My motor has 162 and we just replaced them less than a month ago and they were just fine.. I probably could have gotten another 50k+ miles on them.. Do you people not change the oil? Use cheap crap? Old filters? What? I understand in a high reving motor with a manual it does cause early bearing wear compared to a lower reving auto car.. But really? My car has had oil changes ever 3-4k since its birth and like i said the bearings looks just fine.. I don't understand.. I must be missing something..

I'm with you there. I've seen some pretty high mileage SHOs still utilizing their original bearings. I've always wondered if routine oil changes and quality oil is the #1 life saver for these. Who knows.

How many pepole are the original owners of the car? Mine came with who knows how many miles on the block and who knows if it was the original motor.

My father is the 2nd owner of his and has complete maintenance history from beforehand. Currently just a hair under 300k miles on the original bearings and timing belt.

nice, it'd always be cool to see just how far an original t-belt will go. if it breaks it wouldn't hurt anything on a sho........ The things are pretty durable IMHO..........

Wellllll....I am the original owner of my '95 MTX that had a 3.2 conversion done about 50k miles ago with a fairly low-mileage block (which supposedly had the rod bearings replaced before reassembly), and I disintegrated at least one bearing the other day. Faithful oil changes with GTX, but I always drove it hard. It blew with zero warning on one last fateful trip into the red... Currently considering my options for repair, replacement, or as a last resort, parting out.
