Re: Losing Coolant and dropping oil pressure gauge
If you have to use this stuff make sure that the engine is running when you
pour it in slowly, or you could lock up your water pump or jam your
thermostat open or closed.
If it is not dripping on the ground, then a gallon a month has to be 99.99%
surely a head gasket.

One thing that I like about overflow bottles, is that they are made out of
that kind of plastic that is going to dry out and crack after, say, fifteen
years. Then it will be a special order part or no longer available, and of
course shaped so that nothing but the exact replacement is going to fit.

A pressure tester won't find anything wrong with the overflow bottle, as
they are open to the air, so that should get a thorough inspection.

Yea.. not only do they crack but they make the darn things out of a plasic
that can't be thermally welded or epoxied. :( I've had some luck with
sheet aluminum and rtv/screws.

It will if you use the stopper head from the kit and test the bottle. :)
Guess you could have a new one made.

Re: Losing Coolant and dropping oil pressure gauge
Checked the overflow bottle and it is fine too. Again did the Autozone
pressure test and there is slow dropping pressure but no external leak.
Stop leak is in after running it for about an hour last night. I
pressure tested it againg this morning cold and the pressure drop is
still there. How long does it take stop leak to work?
Well if it's the head gasket then where is the coolant going then?
Trans and Engine oil are not contaminated with coolant
Spark plugs all look okay
It's got me perplexed and at my wit's end so I am taking it to the
dealer on Tuesday, Park Jeep here in Burnsville to have them continue
diagnosing this and the oil pressure gauge too...
Thanks,
Tom

pressure test and there is slow dropping pressure but no external leak.
Stop leak is in after running it for about an hour last night. I
pressure tested it againg this morning cold and the pressure drop is
still there. How long does it take stop leak to work?
Well if it's the head gasket then where is the coolant going then?
Trans and Engine oil are not contaminated with coolant
Spark plugs all look okay
It's got me perplexed and at my wit's end so I am taking it to the
dealer on Tuesday, Park Jeep here in Burnsville to have them continue
diagnosing this and the oil pressure gauge too...
Thanks,
Tom
