Sound on top end of motor

NorCalCoug · 05-09-2008, 02:21 AM

Sounds like a ball peen hammer hitting a block of woot, seems to match revs, very loud. I popped open the oil cap to watch the cams, and it's very well timed to the rotation of the lobes of the cams. Can't tell if it's front or rear bank. No metal shavings in the oil, so it may not bearing related or any shearing going on. No smoke in the exhaust, either.

Collapsed HLA? Vehicle power was otherwise normal, but the car isn't being driven since the sound was heard.

ov3n sent me a video of his car that had a spun bearing.

That's what my noise sounds like, pretty much. Damnit.

i was going to say most people note that a spun bearing sounds like a top end noise ...

Make sure all the spark plugs are snug? Easy to check...

Yeah, at first a spun bearing kind of sounds like its coming from the top end, but as you listen to it more you begin to realize the worst. Time for 3L.

The spun bearing sounds possible... but I am more curious about this 'block of woot' you speak of, and where I can get one!

Well, there is a woot-off today again...

ND4SPD · 05-09-2008, 02:09 PM

So a block of woot... thats like, a block of awesomeness?

Yes.

Motor replacement means no Cougarfest for me. Sigh.
