crossover tube = replaceable?

I know what your sayin Tommy.
Myco said he had the coolent system pressure tested too.

If he had a leak somewere it should have been found during the pressure test.
That includes a head gasket.

how much pressure do you think the "test" the cooling system with?
15-20PSI?

that's ALONG way from 160-180PSI that you find inside the combustion chamber.

like I said, 15ish lbs might not be enough to open the leak, where 160-180LBS PSI inside the combustion chamber could very well expose a cracked head, cylinder or headgasket.

Update: Found the problem. Already called Tommy and told him the good news.

Got home today and decided to take a look under the hood and check out the coolant level. During inspection I noticed (out of the corner of my eye) before closing the hood the very bottom of the engine in the front there was something wet looking on the lip. Thought, "that's odd" and grabbed the light to stick down there. Then I saw a single drip of something had made it to the ground. It appeared something was leaking. Took a look under the water pump and bam. Big giant green streak coming out the bottom. Just to let you guys know. This was not there before. If it was it was nothing of this magnitude.

So there ya have it. Bad water pump. I'm one of the (relatively) lucky few. :yay:

BTW: just for the next guy who reads this thread. This week I have been sitting in 95+ heat traffic for upwards of 30 minutes and also went on the highway for over 10 miles and thought the problem fixed as it didn't overheat. I hadn't completely written it off but things were definitely getting better and attributed the results to the car finally burping itself. Like I said above. The water pump didn't show a leak before or all during this process (of over a month).

Note: There is a litmus test like talked about in this thread. Go to a mechanic shop and they will probably give you it free. I'd gotten one but hadn't used it as my coolant has been swapped twice in the last 2 weeks.

Update. Still overheating on the freeway. The only thing left is the headgasket and I got a compression tester just for kicks to check it out.

When I changed the thermostat I put in one from orielly's. It's a 190 degree thermostat and I have my heater core jumped ( so I'm missing a bit of coolant). With that said. Yesterday I got on the freeway for the first time since the pump has been put in. The engine was hot as I'd been driving all day and once I got on the freeway after 5 miles the temp jumped up to almost touching the first line past normal. I saw it... cussed a bit and since it was rush hour started slowing down because of traffic. The temp went back to normal. Since there was no way to get off the freeway at that point I got over a couple lanes and drove another 3 miles at 60mph and the temp stayed normal.

I'm going to go jump on the freeway in a bit and drive and see what happens. Also, I will do the litmus test (I got one of those) and a compression test. The headgasket is the only thing it could be unless my car is running a bit hotter b/c of the thermostat and missing coolant. This is wishfull thinking though. Soo.. prob. in the market for another engine.

Impossible, the system simply doesnt work or respond that way.

"all signs point to" : suckage, sorry to say

How many miles on the motor?

 

[XLRVIII]

The car has had this problem since he got it.
He's chased it all thru the cooling system...
the motor has gotten hot many many times, and very likely hotter than the gauge ever displayed, due to the sensors location.

This morning I burped it. Warmed the car up... took off overflow cap... opened crossover. Closed overflow cap... filled via crossover... quite a bit.

Drove 45miles on the freeway without a problem. Today was 99degrees outside (google temp not the cars). Worked like a charm. Yay.
