Re: engine knock
Could be a collapsed lifter, change your oil lately?

Re: engine knock
yeah about a month ago. i took off the timing cover and nothing is rubbing. a friend of mine is saying it might be a rod knock.

Re: engine knock
Rod knock would be loud (like HOly Shi!t loud), you would not have much oil pressure and it will destroy itself relatively quickly. My guess would be piston slap. If you could get a video or audio, it would help

Re: engine knock
Piston slap is when the piston literally "slaps" into the side of the cylinder walls normally caused by a bad ring but there can be other causes.
My silver currently has this so if you get a vid up, i could tell you if thats what it is easily. Even without mine for comparison, its relatively easy to tell. |
