I've had a small coolant leak nothing major more of a mess maker than anything.Well yesterday I changed out my thermostat and found the leak at the base of the thermostat housing.Well after bleeding all the air out of the system first problem is the coolant in the resivor is not sucking back in and the another coolant leak is showing up around the base of the distibutor well in that general area.I've wiped everything down real good and still no luck findind the leak.It seems to me that it looks like it is coming from where the thermostat is mated to the block itself.Any suggestions or help would be great.

I know I spelled the coolant wrong my dumbass foregot to proof read the title.

As you probably have figured out, the cooling system will not communicate with the coolant reservoir unless the system is both full and air tight.

So, your first order of business is to find and repair any remaining leaks. Then properly bleed and fill the system, and you should be good to go. I don't know why you are seeing coolant near the distributor, but that's kind of close to your thermostat housing, so I'd take a real close look at that first.

If you don't see more coolant leaking, you might just have to add more to the radiator to bring it up to the level where the radiator can send coolant to the reservoir as it expands with heat, and then you've got things set to work properly (assuming no leaks).

headgasket??? hopefully not but if the tstat isn't leaking anymore isn't the split for the head/block close to that??

Well today I determined it's the head gasket there is small amount of oil in my radiator little floaties when you pull off the radiator cap.Witch leads me to believe the head gasket is getting ready to go.So can any one help back me up on this?Also I searched but does putting the VVL head gasket do anything to your commpression ratio?

The weird thing is no over heating or loss in power.So I don't know I'm going to assume the worse.

Are you SURE it's coming off between the head and block? I had a next to unsolvable at the joint BEHIND the thermostat - where the housing hooks up to the pipes that go around back of the head on a lowport. That was REAL persistent; finally made a gasket instead of just using the goo. PITA.

That's where I thought it was coming from at first but there is oil in the radiator now little specks of it.But there is no coolant in my oil which I thought was weird.

Mmm- don't like oil in radiator. Time to pull the head and true it.

jerryeads you live near Stone Mountain?Yeah oil in the coolant is not a good thing at least I got a good shop I can go do a headgasket in so no high labor bill for me.:)

Did you happen to do a write up when you did this?I thought I read one some where but I can't seem to find it.Also nothing in the FSM unless i'm not looking in the right section.Hell I don't know............
