Coolant issues & name this piece?

So, finally got a chance to look at my new-to-me syclone.

Idles pretty rough and has alot of white smoke coming out the back. Changed the oil for the first time and had about 6 Quarts in it! What came out wasn't just oil, looked like it had a little coolant in it :tdown:

So, started taking a deeper look at it. Pressure tested the coolant system and just dosen't seem to hold pressure. Starting to think Head Gasket, but PO said he just changed them (truck has 57K on it). Ok, maybe he did and didn't change the oil afterwards... So, what else would cause the truck to loose pressure on the coolat system?

Looks like the lower intake to head valley has coolant in it. Cleaned it up, and came right back w/pressure on the system. Ok, problem. Started taking everything apart and got to the intake.

This piece (red arrow, kind hard to see) didn't have a hose attached to it. Is it supposed to? Where does the hose go?

Other arrow (blue) is where coolant seems to be puddling. Any thoughts on what's causing this? Bad gasket?

If the lower intake gasket is bad, can it cause white smoke, or do I just need to pull the heads and check the gaskets? Any other way to check the head gaskets out? Like I said, PO stated he just replaced them...

Re: Coolant issues & name this piece?

had the same problems on mine (smoke from the exhaust, pressure leak, coolant in oil pan).
the problem was just one of the lower intake gaskets was leaking.

there is quite a nice description with pics how to change the gaskets in here or in the s10forum (sorry, can't remember...).

Good info, thanks.

Are the lower intake gaskets same as on regular 4.3's?

It looks better with a cap on it.
It is used on Corvettes to keep the intake from freezing up by running engine coolant through it.
A turbo will do the same thing.
There should be another port on the bottom aft side of the throttle body for its mate.

Are the lower intake gaskets same as on regular 4.3's? NO. Same shape yes but material very different, unless using Vortecs. Victor Reinz makes our intake gaskets.
