Very sorry to read about your engine issue. Does sound like the AOS could be the culprit. Esp if it wasn't replaced wien you put in the replacement engine, no idea how old it might be?

Pelican Parts has a nice write-up on removing the AOS without dropping the engine.

Said to be under 55K miles out of an 05 as a reman from Porsche. Not sure when it was replaced though.

Just to confirm, you tried all these rotations without the belt connected, right?

pull your filter quick. you'll only lose less than 1/2 litre in the process. no need to drain all oil or remove sump yet. presence of metal or not would dictate next steps.

Best advice so far.

Bill, you mentioned in an earlier post that you heard this sound at 3000 rpm. That's above the typical engine speed where high vacuum would be active. So that might not be the same as air being sucked by the RMS.

Drop the oil filter, as RK suggests. Get a really good look. Then decide next steps.

We're pulling for you. Keep your stick on the ice.

Good luck, we are hoping it will be minimal damage

You may have to explain that one to him! He's a born and raised 808 dude!!

I thought I should have pulled the belt but didn't.
Can't touch the car until Monday afternoon when I have free time.
Will start with the filter first.

You're right. There probably isn't much in way of hockey played there.

But anytime I say "we're pulling for you", or "we're with you"; I have to add the last part. Look up Red Green if you're not familiar with it.

Filter is out and I will have a good look when the sun comes out...Stay tuned!

Did you smell a rubber smell when this happened? Burning rubber?

More than likely it sounds like you should have listened to me! (They never do)

Nice post Jake.

Why add the negative smart remark?

Never mind. Dont answer that.

Not helpful.

808Bill

Can't say if it smelt like rubber as I have little sense of smell. Strange thing that happened after a back surgery that almost killed me in 07.
Are you referring to a rebuild of my old motor?

Well, I know everyone is saying to pull the filter, but when was the last time a major engine failure sounded like a screeching belt? Maybe that smoke you thought you saw didn’t come out the tailpipe, but from the belt? Perhaps you have a stuck pulley or accessory that lit up the belt. Maybe a water pump failed. And no, if the water pump failed, your temps might appears fine, as the temp sensor would have been able to detect the increase in temp if that happened.
