Anybody seen coolant sucked into an intake port, and steam comming out the exhaust?

I think it needs a new intake gasket. It doesn't bubble exhaust gasses into the raidiator like I think it would if the head gasket were blown.

Nearest I can figure is a leak from the coolant passage in the head on the passenger side. The intake gasket or a crack in the head.

Its a 390 with edelbrock 6006 heads and rpm intake.

Anyone got any advice?

Thanks

 

Did you pull a corner plug and see if it looks like it's getting chalky looking from anitfreeze? That might narrow it down. I would guess if you pull the intake you might be able to tell if gasket was blown.

Have you tried pressurizing the coolant system and see if you can get it to leak into a cylinder?

 

Thanks Freightrain

I was trying to remember where the heck the cooling passages were on the head and I looked at the new gasket set I have and see that they are indeed outboard of #'s 1&4 cyl on that side. I will pull those plugs.

I drive for about half an hour or more and I have to add coolant. I put an overflow on it, installed a new 7lb pressure cap and an new thermostat. The coolant is not overflowing, nor are there any leaks anywhere.

Hope it's not in the head.

Thanks

 

Yep!

#4 plug had this mysterious green liquid all up in it.

 

I would pull the intake and put a straight edge on it to see if the flanges are not flat. This may cause the leak. Check the head surface also.

I would install intake and see how well it fits(leave gaskets out). Try rocking it around and use feeler gage to find any gaps.

I usually put a thin smear of silicone around gasket(even the ones WITH blue ring) and glue gasket to head with high tack. I've never run into this problem with any of mine.

 

Thanks again Freightrain, will do.

Probably something I did cause I was in a hurry to finish the engine and had to drive it all the way from W. Texas to Orlando without even a decient tune up.

Took it to the track in Orlando and ran a 15.05, still without a tune. They almost threw me out of the track for doing burnouts in the parking lot. Thier just not as casual out here as in W. Texas. My son said, "Dad, I don't think your supposed to do this".
