I rebuilt my motor about a year ago, but i didn't rebuild the head at all. The head has 138k on it. My problem is if i drive for a while, like an hour on the highway, then step on it, it will smoke pretty bad. If i step on it again it will be cleared up, almost like it builds up when i drive and cleans itself out under full throttle. It used to do it a little bit but i notice it alot more without a cat now. Anyways any advice will help, i really hope its valve seals, cuz i'm goin to put cams in it soon. A compression test turned out alright, no big problems, so i am really hopin its the valve seals.

 

bump, please someone help me

 

How about some more details, what color smoke? Is your car running rich or lean? Are you low on coolant? You know, things that will help us help you.

"I mean, help me help you."

 

its bluish with a little black, i'm runnin a little rich. I know its oil, because i loose some about two quarts every oil change

 

What kind of motor do you have? also what mods do you have installed?

 

i have a gsr block with p30 pistons, with a b16 head, the b16 head has 138k on it, thats why i think its the valve seals, the block was rebuilt by me

black/bluish smoke = burning oil

 

i'm very aware that i'm burnin oil, i want to know what is causing it, i explained my symptoms up above, does someone know if its the rings or the valve seals by my explanation???

 

I wish i can be more helpful...

sorry man, i'll keep this thread going till tommorow for you

 

k thanks, i didn't mean to sound angry, i was a mechanic for five years and i built this motor myself, and i'm just frustrated that this is happening after a year, i really noticed the smoke after puttin on a high flow cat, i really hope its valve seals cuz that easy, i can't afford another motor build being in college and all, any advice will help, thanks

 

can somebody please help

 

can anyone please help

 

most likely valve stem seals, check the rings w/out any tools like this: someone has to ride behind you and know whats going on so they can watch. ok, take it easy through first gear, shift to second, romp on it to redline, and just close the throttle, dont hit the clutch, just let it engine brake, if it smokes its most likely rings, if not, its the valve stem seals. of coarse there are other things it could be, but these are common.

 

it doesn't smoke at all on deceleration just acceleration, the werid part is, it will only smoke once after drivin normally for a while, but it does it bad, almost like it builds up then i clean it out at wot, valve seals is what i like to hear

 

Sounds like its your valve seals.

 

Thank you guys very much, I rebuilt this motor a year ago and i'm so scared its shot already, but hearing about valve seals, i'm goin to put skunk 2 stage 2's in and replace springs retainers and now seals, phew i feel a lot better now thanks, I have been readin a ton of people that are havin the same problem too.
