UPDATE: calling JAM in the morning



well im getting fed up with my car

i recently replaced the head-gasket and installed HKS 264 I/E cams and now i have a problem

When i have the car in neutral and i rev the engine by pushing the throttle i get a very loud mechanical knocking sound. I thought i had collapsed a lifter but i just installed the JAM lifters and the noise is still there.

it does not make the sound when idling or when the throttle is slowly pushed. It only makes the noise on quick engine revs.

any ideas?

i just did an compression test and it came out to

155/170/170/165

 

check your oil maybe a spun bearing

 

Damn that sucks. Does it feel normal when you drive it?

 

knocking is common on aftermarket camshafts, but this doesn't seem like the case

 

my bet is spun bearing.. GL with the build. Send it to buschur and get it done right!


make a vid and put it on youtube so i can confirm.

 

will do

 

I wouldnt even turn it over. Could mean the difference from having to replace the whole oil system or even block as well as everything else or not

 

I would have to agree. Most likely a spun bearing. The less you run it at this point the better you are. How long have you been running it with this noise? PM me maybe we can work out a deal.

the noise started when i was on my way back to my house, maybe 200 yards away, and then ive idled it in the garage for maybe a total of 3 minutes

 

if it was a spun bearing it would've started life as a small clicking sound prolly atleast thats how mine did, i never let it get to knocking.

It might have just progressed from small click to rod knock and thats when you noticed it.

 

Mine just started making a noice like that and i thought it was lifter tick... guess it may not be...

 

did u ever change the clutch?...could be a loose flywheel.....which would sound like that

 

This is how mine started, but I did let it get to the point of knocking unfortunately

 

Im trying to figure out what the noice is as well but i have a act 6 puck no springs with an extreme plate, i also put a light weight fly wheel...
