my opinion is cam pulley or a engine pulley i had a weird noise close to that took off the cam gear cover tightened the bolts and took off the valve cover and tightened all the cam shaft bolts and it was gone but huh try what you think first

@cubcadet1983 Well..two years later, this motor is in my back yard with a rod out the back. I discovered two spun rod bearings and while trying to make it to my buddies garage to pull the motor, a rod shot out the back. No big deal as I was trying to pull it anyway. Got a 600+ build going in this now. I really wish I would of known then, what I have gained in the last 2 years. Anyway...I am hoping for 600whp on pump on the HTA3586.

yo thats definetly your valves are bent, it might have to do with your timing belt, it should need reservice every 100,000 miles or so

Im ready to dig in to this thing now that the holidays are over. I am hoping its the head but why do you say its bent valves? These are new valves and guides. Do you think when he put the motor in and he ran it out of time , it bent the valves? How can you tell. Why does it queit down .? Im about to crack this open in a few days. Thanks

@manuelbou you dont have any idea what you are talking about.

DSM timing belts are supposed to be replaced at least every 60k and if it had bent valves it wouldnt be running, the car has rod knock.

[NOCLASS2G]

mine did the same exact thing..i brought it in to a shop to get the idle adjusted and the knock was only there for a night after running it hard. it went away and now runs smooth as ever. idk what to tell you man..adjust the idle.

[cubcadet1983]

wow good luck i hope to see a vid soon

[mikedsm12]

it sound like a lifter or the oil jet lifters that exspand when oil pressure hits through the head. a couple of them could be stuck or a rod knock. sounds more like the lifters though. ive owned many dsm man :) hope you fixed it by now? ya

@manuelbou fucking tard. Its not bent valves. dont comment if you dont know jack shit about cars. It could be one of many things. If it goes away when the car heats up it could be piston slap. If its constant and seems to go with the rev of the engine which it does, it could be a worn connecting rod bearing Its nothingfrom the valves or lifters I can say that for sure. The noise from the wheel well def sounds like either your p/s pump,or coolant pump bearing.

Ohhh! This is piston problem!! No rod and bearing, no crankwalk, etc ......

Piston cower is broken (or sleazy), piston swing to cylinder.
