Lower intake gaskets

[kenconerly]

Would bad lower intake gaskets cause smoking out the exhaust. Also cause my sparks plug to become wet??

White smoke? If so that indicates coolant is being mixed in with the oil and it's probably a lim issue.

Yeah.. when i took the intake off one the port were clogged. Could that be the problem. Or should i take the head off. I have a pic but i cant uploadd it

what engine do you have? n/a and it could have a cracked intake still that you missed.

Create a pbotobucket account, upload there and then post the IMG tag in here.

Ports clogged is probably from air getting into the system causing the Dexcool to gum up but you can take care of that with a lim job and fluid change.

Edit: I would not worry about the heads at this point.

Its a 98 3.8 s/c... the gaskets do look bad

Yup lim gasket first and when your there flush out the Dexcool and use another coolant (I like green) from autozone or something but I wouldn't drive the car any further until you get the coolant out of the oil.

[Scottydoggs]

do you have the lim off the car? or you changed the lim gaskets already or your thinking about doing them? not sure what the plan is.

but spark plugs with coolant on them is not good. that would be the head gaskets. did the engine over heat bad? and i assume its eating coolant?

time for a compression test. go from there if im reading any of this right.

I replaced the head gaskets last year. And since then the car havent overheated it just started smoking about a week ago. I was going to have the head checked. But i saw that. My phone let me download photobucket. Could i email you the picture

Heads and head gaskets aren't typically a problem area on these motors. Check your oil for milkshake. Don't want your bearing bathing in the nasty stuff.

most of the time on SC motors i find the paper tb gasket has hardened/shrunk/cracked and lets coolant get ingested from the tb coolant passage.

most of the time you can pul the TB and see raw coolant in the divot in front of the EGR passage of the blower inlet
