So you guys remember my headgasket problem well i bought this stuff to seal the headgasket and it worked great, only problem is this stuff is thick and gunky so it wants to block up the radiator. Well i flushed the engine twice and i have driven it for two weeks now and it was like new. Well last night im driving and i notice my heater is putting out some really hot air but i dont even have the fan blowing. So i look down and see the temp. gauge shooting up all the way till it cant go anymore so im like SH!T and turn the heater on full blast to get the hot air out of the engine. Well doing this brought it down to 3/4 on the gauge. I got home and opened the hood and the gunk stuff pushed all of the antifreeze into the resevoir. Well im like k thats why then and then check the oil and there is not a drop in it. ah fawk. Now it drove home fine. Today I go out and put oil and oil treatment in. Flushed the gunk from the engine and radiator again and put new fluid in. I also changed the fuel filter. Started it and ran fine. I took it out and wow it was basically a smoke maker rather than a car. It was putting out a HUGE amount of smoke and if i would stop it would want to stall. Now after driving it for 10 minutes or so it stopped smoking totally and ran perfect, even a tad bit more power it seemed. So im like k??? I came home and went to drive it like 20 minutes later and it was making HUGE things of smoke again. What the hell is this guys? Im pretty down about it right now dont no what to do. Why would the smoke go and run like that then be fine after like 15 minutes?
thanks a lot

almost the same **** happen to my gf car.. i put in that "stop leak" stuff and later on the radiator blew up..the upper plastic part cracked. so had to get a new radiator(got a dual core all metal one at radiatorbarn.com) it run good now but i think the themo and fan is f ck up in the car. but since its pretty cold here so i didnt replace it yet...

oh yeah the smoke...i think its the water/coolant boiling up and spilling out from the radiator (that what happen to the car) white smoke/steam or it got f ckin hot and the oil burnt (gray or black smoke??)

 

I put that stop leak stuff too inot the radiator. And my car over heated. I'm still in the process of draining the car...it's been 3 months...lol

 

On my old 92 Teg GSR, when my radiator cracked at 115K, I dumped heaps of that stop leak stuff in... and my car steamed/smoked at every single stoplight as the leaking mixture leaked, heated up as it hit the block or whatever else was hot...
I had like 10 different drivers roll down their windows and tell me my engine was dying. I also got a dual-core all-metal replacement... much, much better.
