Uh oh... this is bad

You mean on the lower intake mating surface. I just did the lower intake and I only used a sharp putty knife followed by green scrub pad and an exacto knife.

I didn't want any grit in my engine.

Yes, it requires lifting it up at least 6 inches...
But if you aren't getting any fluid in the oil you should be ok... But after you get everything done again, do an oil change to be on the safe side.

Either way, you will have to pull the heads and lower intake to replace the head gaskets since coolant is getting into the chambers.

YOU MUST MAKE SURE THE MATING SURFACE IS 100% CLEAN for the new gaskets or you will have to do it over again. To prevent debri from getting in the valley, simply use newspaper. (If any falls in the cylinders when you have the heads off, it's no big deal as you can just blow it out)...

So SAND down ALL the mating surfaces, they should be pristine when redoing the heads. Make sure they're torqued right and that you relash them properly...Everything should be ok then.

Seeing you are stating there is no coolant in the oil, you are safe.

I would replace both head gaskets but don't disregard that it might be that intake gasket you installed.

Did you install it to the proper torque spec?

Yes. Torqued to spec.

Relash them properly? What does that mean?

Did you use gaskets when you put it back together?

This is not me, administrators are tracking this guy right now and his IP address is logged and currently being traced.

Relashing the rocker arms. This engine (W) does not require lash adjustment, you just bolt them down to spec, I think its 20 foot/lbs.

Yes, the spec is 20 ft-lbs for my engine.

'93 and prior required adjustment. Mine is a '94 and does not require rocker arm adjustment.

I'll pull all the pushrods and check to make sure they are in spec and are not worn. I'll make sure to put the rods back in the exact same place they came out of.

This might be a good time to change the valve stem guides anyway. I don't know anything about this vehicle. Everything seems to be pretty bad off. Might as well take the extra time to check everything right the first time. I hate having to do things a second time.

I just had another suggestion that the oil in the coolant may be coming from the oil cooler in the radiator. The radiator was the only part of the coolant system that I didn't replace. I figure it is worth a shot and since it is about 10 times easier to replace the radiator than the head gaskets, I figure I will give it a shot. I'll probably have to replace the head gaskets too, but what the heck.

Could be since engine oil pressure on average is higher than antifreeze system pressure, allowing oil to get into the antifreeze and not as much the other way. Explains why you are not seeing antifreeze in your oil, but doesn't explain why you are seeing white smoke at normal operating tempature out the tail pipe. A good idea would be to get the rad pressure tested at a rad shop or get a engine leak down test. The leak down test will let you know what going on with your engine.

I had a mech do compression tests on the engine. He seemed to think that there was an internal head gasket leak. I don't know how he figured that out.
