Knocking Noise from Engine

I have a Knocking noise coming from the Engine when I first start the engine and when your hard or the gas or at the top of the revolution of a gear. I have checked the Flex plate and have check the to see if it was a lifter or a rocker cause I have removed the Valve Covers. Also I have alot of Oil presure since it is splattering oil away about 1 foot away so I know it is not that. Anyone got a Clue what else it can be? I am going to check the timing next after I put it back together. please writing back or email me direct with replys to [email protected] thanks.

Re: Knocking Noise from Engine

Hi,

Have you tried different brands and/or octane gas? Any change by doing that?

There is a knock sensor that's supposed to help cut things down, and might need replacing, but I would check the different gas first. Do a full tank of premium to see if that helps...

Your profile doesn't mention what type of vehicle you have, what engine and what year.

Re: Knocking Noise from Engine

You sure it's not a spun bearing?
I had that same problem with the 2.8 I had in my '83.
It only knocked at startup and at the top of the rev, just before upshifting. When it happened to me, it was the #3 piston bearing. too $ive for someone who was broke as I was to fix, so I junked the engine, dropped in a second-hand 2.8 I got from someone for $175 bucks, and drove it for a few months until it blew up too [img]images/icons/tongue.gif[/img]
