i think i have a broken LMA because it sound like a bad rod bearing but when i put my head to the motor it sounds like its come from the head. I was told if it sound like a bad rod bearing but what are the sounds and signs of a broken Lost assembly. Please someone tell me the signs.

Lost Motion Assembly..

 

you can rev the engine to over 3k and engage the vtec solenoid, if noise stops there you have it.

 

yeah it no tmy LMA is a spun bearing all well back to the drawing board.

 

If you suspect rod bearings pull the fuel injector connector off 1 at a time while idling. It'll stop knocking when you pull the connector of the offending cylinder.

To check LMA's, remove the cams then push on the center rocker and check for smooth movement.

Never thought of that. That's freaking awesome lol. You learn something every day.

 

youd think itd still make some knocking sounds since its still rotating just doesnt have the cylinder pressure acting upon it
