Default Yet another Upper intake topic

So i'm losing tons of coolent, a gallon in 2 weeks. I thought it may have been the water pump, becuase i saw some leaking around there and a puddle forming underneath it on the ground. But suddenly its not leaking on the ground anymore, yet I'm still losing coolent. I'm nervous abotu that intake.There'* no noticable coolent leak around the intake... I know there'* info about changing these on this site, but i couldnt really find it. Also do parts stores carry these in stock usually?

I went through that before. If I get your phone number I can tell you all about it. Also, what the hell are you doing with green coolant?

I'm gonna take a stab at something, and I am probably completely wrong, but I have been thinking about this.

What is Dexcool? (Yes I know its coolant) but what is it engineered to do?

Lemme take a stab at my own question.

Modern engines are very heavily engineered and produce wacky amounts of heat in order to operate and pull a vehicle. The Series II 3800 in my estimation is a modern mill and thusly produces more heat then say an L27. Therefore a new method of cooling these super hot engines was engineered.

The resultant product = Dexcool. NOW, is it possible that if a Series II engine is running old skool green antifreeze, this product is not doing the job that it was engineered to do. Now common knowledge states that heat will cause a liquid to evaporate or burn off. So, is it possible that the heat generated by your Series II 3800 is burning off the green coolant.

If all the gaskets and intakes and other mechanical riff-raff has been fixed and accounted for, then maybe I'm onto something...

Or maybe I'm rambling.

I look forward to being proven wrong, I really want to learn here.

Dexcool is just a different blend, and it'* just for "long life" If you did a proper switch over that'* not the problem.

The L27 doesn't fail like the l36 because it was designed right Modern HA, they just wanted over 200 hp. but only needed a 5 lb/ft peak... but that'* a differentt discussion.

Drive the car to a shop now!! You don't want a hydrolocked engine, due to coolant in the oil.

My car came with Green coolant, the previous owner flushed it the first time the Upper Intake Manifold was fixed. Frankly I'm just as happy that the green stuff is in there now....

Definitely get that looked at, and I'd do a oil analysis on your engine too once you get it fixed to be sure there are no more problems. There are a number of labs on the 'net that you send a small sample of your oil to and they can perform tests to see if you still have coolant (or other!) wear issues.
