Another motor problem

[cekim]

I did not pull both off, just the driver side as it seemed that is where most of the noise was comeing from. I am running the MMR Stage II heads with the 1mm oversize valves. What would I be looking for when I pull the covers off if this happend? would it be obvious damage?

It's tough to diagnose sounds over the internet, but a rocker tap is usually higher pitched/toned than a bottom end bearing...

A rocker tap is usually slower than a bottom end bearing as well - main/rod bearing will tap once per revolution most of the time where the cams are going slower than the RPM...

If you want to rule out either, you would need to:

1. pull off the valve covers and check for cam wear, loose rockers or dry rockers (they should all be well soaked from the "lifter" which is where they get their oil). You'll need to rotate the engine/cam around (with the plugs out) for every intake/exhaust valve to checking each rocker for slack on "round" side of the cam lobe.
2. pull off the oil pan and remove/reinstall one rod and then one main bearing at a time to check for wear...

Without being able to hear it, I can't really say if such drastic action is justified...

Man that sucks! was there any damage to the cam on yours Freak? Did MMR reimburse you any? Mine is pretty loud and it will not be started again, i have already pulled the blower off and its not going back on till I find the problem.

the cam just needs to be polished im real real lucky i caught it when i did and shut it down early as far as mmr well we shall see i have to send them in the old valves so they can send it to the manufacturer and have them tested and MAY refund depending on the results but that still really doesn't do shit as even if they do the main cost will be the new ones , labor , and gaskets fluid ect. so i still get the rod either way ......now it would be nice if they did but we shall see im still waiting on the fucking manley valves which are backordered for like 2-3 weeks , yep i know that sucks

Man, I wish you luck Freak.

Thanks for the input Cekim, I understand how hard it is to diagnose over the net. I have a hard time explaining it! But I do appreciate all of these suggestions. I beleive that if it sounds bad (which it does) Then dont get your hopes up.
