soya_sauce Posted April 3, 2006 Report Posted April 3, 2006 hey guys i started my lumina for first time all winter today, its been in underground storage all winter long. im a little concerned though. im hearing a knock coming from the vavle train, only when you rev the engine up. Sounds similiar to the knock a rod bearing would make only its definetly coming from the front bank valvetrain. im curious about cam bearings in the dual ohc engines. Are they a common problem?? difficult to change??? any info or ideas on what may be the problem would be greatly appreciated. thanks Quote

How long did you let it run for? Shouldn't be a knock, moreso a tick. Quote
synistershadows Posted February 19, 2008 Report Posted February 19, 2008 I just started haveing this same problem with mine only i have been driving it pretty much everyday it is over due for an oil change though but could that cause this problem? Quote
synistershadows Posted February 19, 2008 Report Posted February 19, 2008 resoline?? i take it an additive? Quote
IRONDOG442 Posted February 19, 2008 Report Posted February 19, 2008 Yeah it quiets ALL valve train noise ask Dinunzio !! Quote
synistershadows Posted February 19, 2008 Report Posted February 19, 2008 where could i et this any auto parts store? Quote
nequamminor Posted February 19, 2008 Report Posted February 19, 2008 I dunno about additives... I'd check out this site and make an educated decision after that. http://www.bobistheoilguy.com/ Especially the part mentioning the Lucas oil additive, which is waht I thought was a good additive until I read that article. http://www.bobistheoilguy.com/images/lucas/lucas.htm Quote
IRONDOG442 Posted February 19, 2008 Report Posted February 19, 2008 Resolone isnt an additive its more of a detergent designed specifically to quiet valvetrain noise. Quote
GOT2B GM Posted February 19, 2008 Report Posted February 19, 2008 I'd let it warm up to operating temp and see if the noise goes away. One of the lifters has probably lost its prime. Whereabouts are you in Kitchener? Quote
synistershadows Posted February 19, 2008 Report Posted February 19, 2008 where might i get some of this detergent? Quote
synistershadows Posted February 19, 2008 Report Posted February 19, 2008 and i have let it run up to temp and it still makes the noise but only when i step on the gas Quote
IRONDOG442 Posted February 19, 2008 Report Posted February 19, 2008 Any Auto parts store its about $6.00 a a quart follow the instructions on the bottle. Quote
GOT2B GM Posted February 19, 2008 Report Posted February 19, 2008 and i have let it run up to temp and it still makes the noise but only when i step on the gas I was responding to the original thread question. Quote
gp90se Posted February 19, 2008 Report Posted February 19, 2008 drain the oil, put in 5 quarts 5w30 synthetic and a bottle of CD2 valvetrain noise stuff. Patgizz swears by royal purple, I'm a fan of syntec. Quote
gp90se Posted February 19, 2008 Report Posted February 19, 2008 they changed formula, i read it doesnt hold up as well as it used to, been a while since I read up on it. Quote
synistershadows Posted February 20, 2008 Report Posted February 20, 2008 CD2 valvetrain noise stuff. what is this? Quote
93CutlassSupreme Posted February 20, 2008 Report Posted February 20, 2008 CD2 valvetrain noise stuff. what is this? Synthetic urine. Quote
synistershadows Posted February 20, 2008 Report Posted February 20, 2008 ok so i just did the oil and added some resoline and nothing happend so i took a video of what im hearing please help me out guys i need this fixed asap http://s7.photobucket.com/albums/y294/aodei/?action=view¤t=19-02-08_1923.flv Quote
joeld Posted February 20, 2008 Report Posted February 20, 2008 Remove the serpentine belt, this will isolate w/pump,power strg pump, etc. and listen for any change. Could be a something other than engine noise. Good luck Joel Quote
synistershadows Posted February 20, 2008 Report Posted February 20, 2008 the sound is comming from the opposite side of the engine its on the drivers side front bank of the heads least that what it sounds like Quote
19Cutlass94 Posted February 20, 2008 Report Posted February 20, 2008 You can spend all day guessing what the noise is. You can try many many weight oils and that may not even cure the problem. I suggest you go into the engine and find out whats causing it. Quote
synistershadows Posted February 20, 2008 Report Posted February 20, 2008 so pretty much take it to my mechanic Quote
88red4cyl Posted February 20, 2008 Report Posted February 20, 2008 Unless you want to tear into it, then yes. Quote
