What could potentially be the problem? The valve cover shows no cases of timing chain damage, but the guides ARE removed. It sounds like a mild knock sound, but it has been doing this for over a year, since my buddy had the car before me. The car runs and performs excellent, and does not eat any oil. No smoke, and it passed emissions last year without a problem, even with the EGR blocked off. It has about 10-15 thousand miles on it, and compression test is excellent.

Whats the deal?

EDIT: Here is a video of my motor running at idle, and revving.



Thanks in advance dM drift junkies

i notice a few things wrong with your motor.
you have a gay radiator hose.
you have no mechanical fan.
you have alot of rtv where your valve cover gasket should be.
you've been krogering.
your motor moves too much.
your airfilter looks dirty.
it looks like a ka.

i have some wheels like your front wheels for sale if you want.

SR will fix that

if it is not running bad and not coming apart why fuck with it?
