just like the topic says. Mine slipped. We have to take the pan off to see what happened and/or tear apart the motor. and see how bad it is but after draining the oil and looking at the filter we were able to see the gold metal sparkly stuff in the oil which is bearing.

I don't think this is common so I want to know what to look for and examine. I want to find out what caused the problem rather than just replacing the bearings and slappin her back together again..

 

Spun bearings are kinda common for these motors. you don't see it alot, but it does happen. Try a search on this and you should pull up a fair amount of information on it.

 

i think i spun a bearing also. just done it last weekend so haven't had a chance to tear it down yet but i'll probably just bite the bullet and get a 402.

 

spun bearing = lack of oil or any foreign substance/object mixing with oil..ie aluminum or antifreeze, etc..

 

Exactly...the oil film was sheared or lost....

 

Main bearings aren't so common as the rod bearings are. The mains are actually pretty decent for a factory setup. Rod bearings spinning is alot more common and is usually due to eithor like somebody said oil shear or the rod bolts stretching or a combination of the two.

 

My $20 bet is that you've spun the rod bearing(s). That's most likely. Lack of oil film @ high rpm.... and the list goes on. Bummer.

 

wouldnt the oil pressure drop also as soon as it goes?

 

Yep. These engines have a tendency to lose oil pressure at high rpms should the oil level be like 1 quart low. Another issue is weak fasteners. You have to remember the general only builds things to withstand the limits of stock RPM abuse, you can get away with a bit more prolonged RPM on the LS6...

 

Not having spun a bearing before, what's it sound and feel like?

 

horrible knocking in some cases.
