You didn't do the test correctly. You have to have the rubber cone in the radiator hole 100% tight. It has to be hermetically sealed in the hole to draw in the exhaust gases and detect them.. The way you had it - it was loose and sloppy - this allowed the exhaust gas to escape out the sides.

That doesn’t matter. I’ve tested head gaskets all sorts of ways. I’ve tried the “wrong way” on purpose and I’ve tried the “right way” on purpose. Both ways gave the same results. I’ve been doing this 15 + years. To each his own. 👨🏽🔧

I have a question: My 1999 f150 4.6 V8 is leaking coolant externally on the pass. Side between head and block at the front cylinder and now i noticed that on the back cylinder is getting coolant into the piston . Is that for sure a blown head gasket? Thank you.

Alex, I have this same engine in my 05 Malibu, at 322k miles now. It has a big oil leak from under the t stat where the lower intake meets the head. I took the car apart and checked the lower intake gaskets and they seemed fine, had them done about 50k miles ago with Fel Pro ones. I put some Permatex black in the corners to seal it up and put it all back together and it still leaks and now i have a noise like in this video, the noise only happens if i floor the accelerator. If i dont floor it but still rev it high doesnt happen. Car runs great, power is great doesnt overheat and heater works well. Any ideas? Is it possi le to leak oil from the head gasket?

Your spot on I'm not having those issues there's no milky oil or coolant but bubbling in the radiator. No Smoke coming out the exhaust replaced the radiator 6 months ago and now overheating and head gasket warpage it looks like there's no where for the coolant to go, it sprays out the reservoir

My rav 4 is currently in mechanics for last 2 weeks getting its head gasket issue resolved it had a external coolant leak turns out 2 of the cylinder head bolts have lost all their torque threading and were just sitting in the holes my mechanic is waiting on a tapping kit to re-tap the holes and put new bolts in there thankfully only a very micro tiny amount of warping happened on cylinder head as result of putting in temp seal and no damage on the gasket head

Yeah my 07 charger RT head gasket failed. I didn’t know it was the head gasket because no coolant and oil mixed but there was a lot of white smoke coming out the exhaust.

@@DJR5280 piece of cake, really. Biggest problem was finding head bolts. Fel-Pro sells a “set” that’s enough to do one head only, and they were out of stock everywhere at the time.
I learned something about blown head gaskets today. Thanks Car Dr.! So nine hours for a professional, that comes to three weeks for me if my math is correct.
