Smoking 304

Started pretty soon after I put Edelbrock intake on. She's smoking only out the left tailpipe, very light colored smoke, grayish white. Also wants to foul out the first plug on the drivers side. So how do I figure out if it's rings or intake leakage or head gasket?

PS--Has to run a few minutes, before it starts to smoke. Then if you gun it a bit, it'll kill every mosquito in the state!

sounds like you have a leak on the front driver side

did you try to tighten the intake bolts up?

Yep

I retorqued them yesterday, then started it up and it was smoking just as bad. I guess if it blew out some gasket sealant while they were loose, tightening up wouldn't help a whole lot.

Well, if I knew for sure that's what it was, I would.

1st plug on the driver side is next to the intake runner for # 1 cyl. most like it is seaping into the runner every thing worked befor the intake swap? - did you use anything to seal the water ports in the intake? or the runners for the heads?

Yea, it worked fine, just smoked a little bit. I did run a bead around each port on both sides of the pan gasket. I sure HOPE it's the intake!! I did NOT ever check the torque after the initial install, I guess that aluminum expanded and shrunk or something, cause they were torqued right, but when I checked them yesterday, they were around 15-20 ft-lbs and were supposed to be 40-45.

they will loose torque after the first few heat cycles..dew to the gaskets shrinking by the heatThats why its imperitive to retorque them at least 2 times..I often retighten after a few hours and about a week,just to be sure..I would pull it off replace the sealsseal the water passge ports and tighten them down with the proper tightning sequence..I downt know if any intake bolts go in a 304's water passage in the head but if they do its wise to put some sealer on the threads..

Can you reuse the valley pan gasket?

After talking to a bud, I'm pretty sure it's the gasket (intake). Does anyone know if you need a special gasket when replacing the stock intake with the aluminum Edelbrock?

Thanks in advance!
