what is this... lol please help

[Joseph_98]

Just started out of the blue..

That one is hard to tell. Have you over reved the engine lately or has the oil gauge dropped at anytime ?

[SteveC]

That is a "rod knock" if I ever heard one, you MIGHT have a clogged oil port, you may consider draining out about a quart of oil, and replacing it with a quart of transmission fluid, run the engine @ 2k rpm for about 5 minuets, drain the oil, change oil and filter, then start it up. With any luck the transmission fluid MAY have unclogged the port, if not it is rod or lifter replacement time.

JMHO

Doesn't sound like piston slap or a bent push rod to me.

Have you been able to use a long screwdriver or similar to try to pin point the origin of the sound? Like, where it is coming from? Hopefully not from the bottom end.

Well we narrowed it down to the drivers side head ... now just have to play the impossible game of can I remove this without pulling the dam motor

[cammed goat]

For added peace-of-mind, check the manifold and gasket for leaks before you pull the head. A leaky manifold/gasket could mimic a rod knock.

Bad rod bearing.

Bad rod bearing.

How would it be a bad rod bearing if he said it's at the top of the motor?

The sound is coming from the bottom end and transmitting up through the engine compartment. Trust me, it's a bad rod bearing.

I'd climb underneath and put a stethoscope on the pan or block. That pitch sounds like bottom end or a cracked flex plate if you have an automatic

A cracked flex plate will sound exactly like a worn rod bearing. I don't know if he has an A4 or M6.

Do you have aftermarket rocker arms ?

[cammed goat]

Agree with Keith. Might have a rocker arm that is out of adjustment if it's aftermarket.

OK. I trust you.

[2002ssslp]

OK. I trust you.

Well, it sounded like a bad rod bearing to me at the time. lol
