Engine is a forged B16 stock bore, 3 layer headgasket and the block and head were both checked by the machine shop and are good. I have no visible water leaks, no oil in the coolant or vice versa, no hydrocarbons in the water either so the HG is good. It is dissappearing at a rather impressive rate though like 100 miles and I will look into the radiator and its down to where you can't see the water anymore.

I completely drained the system last night, changed the Tstat since I was in there already and then used some bars stop leak and water, ran the car until I had all the air out and then took it out for a good amount of fairly spirited driving.

Let the car cool back down and I only lost about and inch out of the cap so it's slowing down but still going somewhere. What do you guys think I should try next? Drain and flush one more time and use the copper bars sealant or what? I hate leaks that are un locatable. Thanks for any help.

Goto your local parts place and get a cooling system pressure tester. Use it to pressurize the system and you should be able to visibly see leaks or hear them. Give it a shot, couldn't hurt any.

Aftermarket sleeves sir? What brand?

Jay_Sensing

sleeves are stock, no HC in the rad so I dont think HG or cracked sleeve, Cap could be the prob but today after another 100miles or so, I was barely missing any coolant so maybe the chincy crap I put in the rad is doing its job.

Sorry for th crappy typing, just got out of ER, had a mishap with a compressor and a suspensin and have onne working hand and a lot of owie lol, I cant type like this for ****. I will try the pressure tester tomorrow if I can make myself get out of bed

It's interesting to see others are having the same type problem. Mine is doing the same....not as fast as yours and I have ERL sleeves. I'm not trying to jack your thread though, I just wanted to let you know that you aren't alone.

Is your radiator new or old?

ScorpioMk

do you still have the tube that goes to the bottom of the overflow tank? i dont know how mine was missing but the radiator would warm up and a little fluid would go to the tank, and when it cooled down it wouldnt suck water back into it. so after a few drives the radiator would start to get low and the engine would start to overheat. live and learn.

rad is original but no bent fins or anything, looks to be in good shape,


Scorpio, no I do not, that damn well may be the prob;em, something I didn't even think of looking at. Thanks man, will give that a try today.

Dunc

and what if we (I) still have the tube in the overflow can? haha
