any suggestions/
 

hey guys, my built motor on cold start up get like valve ticking/chatter then when its warm goes away but now it is constantly there anything above 2500rpm it follows with rpm, ... And my bov sounds a lot more high pitched then usual which is really weird. took vc off and looked at the lifters springs etcc etc and cranked it everything seemed to be fine.... but still hear a noise clankin on the passenger side of the vc around the timing chain area my 58/57 boosted perfectly still anyone got a idead of what could be? streched chain?

Is the chain guide loose?

might be im ripping the timing cover off and checking everthing out tomorrow

chain guides were broken in 2 pieces

ive had mine replaced. i think it is a common problem,but not every cobalt has this problem.

how the eff does that happen?

they are plastic but still dont know how they would just break

i dunno how lol? 510whp have anything to do with it? or just shitty plastic crap lol

mine were broke in 2 spots also...all wooping 240 WHP when i was bone stock lol

chalk it up to good'ol gm parts lol

that part was probably made in canada :spam:

ezzzzzzzzzzz
