Fixed my boost issue.....but spun a bearing this morning

[green-lantern]

Cut the oil filter apart

Most definitely

[J. Fast]

Not true. I had ZERO flakes in my oil or filter, but had a rod bearing completely spun. Pickup was catching it all and clogged. I shut it down quick so that probably helped. Oil had a bit of a sheen though.

Old engine or new build?

[familyMAN]

Newish build. Why? There were flakes "all up in" the pickup, just didn't make it anywhere else

[Chris@Rvengeperformance]

The filter catches all the smallish stuff and the pickup screen catches the huge stuff. There was barely anything in my drained oil.

"Drive it and be happy" I think were the words preached to you. Sucks you didn't listen.

Newish build. Why?

Because bearings don't just spin and let go. As you know, they're quite durable. You can smack them with a peen hammer and they don't dent (actually watched my buddy Dave Landry do it to prove a point once). The conversation that shortly followed the demonstration went something like this... Bearings are retained by bolts and require lubrication. Bearings spin when clearances aren't appreciated, retaining bolts are improperly torqued, when they reach a maximum material fatigue/wear point (only on old builds or seriously track only racecars), or the rotating assembly overheats from a lack of lubrication or oil cooling. As you can see they are quite durable.

You got lucky, however, you're spun bearing issue was installation error not fatigue. It was a newish build, never tested or proven. Mike's build has been leaned on for a long time and he changes his oil like every 1000 miles and it's clear on the stick. It doesn't burn oil, make noise, knock, nor has it ever had oiling problems. The first time he cranked the boost up on that thing with improper oil cooling, lubrication, poor clearances, or improperly installed retainer bolts it would have come apart. Engines don't last long when you're making 500 horsepower and 600lbs of torque and F-up a build. They come apart really quick (few hundred miles). Mike's engine lasting many years and never being line serviced with numerous track passes without failure leads me to believe the engine build is fine and the problem is something else all together. Now, blowing a hole in a piston and sending metal into the oil is not spinning a bearing. IMHO you really have to make a big whoops to spin a bearing. Drive with oil pickup/galley blocked, use shitty broken down traditional oil, reach a bolt or retainer fatigue point (push an engine beyond it's design limit), miss a step in rebuild/re-assembly, or make a mistake in the build. An engine won't last one race or 1000 miles once you cross one of those lines. Mike's rotating assembly was built to handle 1000hp which makes me skeptical in hearing spun bearing. Engine failure, yes, possible from detonation. Spun bearing... Poor assembly or lack of lubrication? Meh, NOPE!

^all of that has nothing to do with my original post. YOU CAN HAVE A SPUN BEARING WITHOUT NOTICEABLE FLAKES IN YOUR OIL.

You are so predictable though. Obviously I knew your question was loaded and wanted to see what rant you would go on.

Now continue on about my engine or maybe forests, neither of which have anything to do with Sins issue in which he should be cutting open a filter and dropping the pan before you or anyone jumps to conclusions or pointing fingers at stuff that has nothing to do with his issue.

[TwIzTeD_3kGt]

Aww that sucks man. Knocking is no fun. You sure it's not maybe a TOB or something else? I'd drop the pan before running it again.

[green-lantern]

BTW Mike, if you’ve never cut a filter open cut around the side that screws in but about ½ inch from the end. I’ve found it much easier than trying to cut at the very end.

[Chris@Rvengeperformance]

Uh, the tune can certainly pound out bearings in a hurry. If you don't know that you shouldn't be tuning or giving advice.
