I noticed coolant between the pass. side valve cover and the intake manifold yesterday and soaked it up with paper towels. I drove her 70 miles this morning and its back.

I was thinking intake manifold gasket but doesn't the coolant usually mix with the oil? I drive at least 150 miles a week, check the oil every week, and it looks great.

What do you guys think. This is my daily so I'd really appreciate the help. Thanks.

First thing to do is clean the area off...but...it looks like its leaking from the radiator hose or thermostat housing.

Now that I took a closer look it does look like theirs a mark going down the manifold from the housing like it was wet before. Will putting gasket sealer around the housing then bolting it down do the trick?

What kind of gasket did yu use? I've never had to use sealer. You might check the housing and the manifold to make sure they are straight. If you must use sealer, get The Right Stuff by Perma-Tex.

The thermostats in my 87 and 92 use a rubber ring seal around the outside of the thermostat. Those do not come with the stat and have to be bought separetly. O'reilies has them separate.

Hmmm. When I got the thermostat, from oriellys, it came with that rubber ring. Think I'm gonna try the permatex. It's a tiny leak so it should get the job done.

Cant believe I was thinking it was an intake manifold gasket. I need to take it slower next time and thoroughly examine.

I just ended up tightening the clamp on the hose real good with a 5/16 and rachet. Took it for 60 miles, checked, not a single drop. I think I'm going to start using the 5/16 instead of the flathead for these clamps
