I changed the oil in my 98 Camry 4Cyl 70k mi yesterday and found foam in the drain pan. I realize that this may be an indication of cracked block. Is there a test to determine if the foam is caused by coolant. The oil has been changed consistantly every 3000 mi with the recommended 10w30
I would also like to get opinions on the following...a possible cause to the above.
I brought the vehicle into a quick lube place to get the coolant replaced (the only thing I let these guys do) I was watching them as they hooked up the drain and fill machine. The draining part was happening nicely. Suddenly one of the Bozos realized that the "Fill" part was not happening. As you know the vehicle is running during this process. I suspect the vehicle ran a few minutes without any coolant. Meanwhile one of the "automotive experts" noticed the temp gauge and proclaimed "this thing is gettin' reel hot" at that point they figured out that you have to turn the valve on to let coolant back into the engine. Coolant then was introduced into hot engine. great. What do you think? This happend about 4 months ago.
Unrelated to the coolant issue one of the Bozos decided to check my oil filter while he was wating for the coolant to pass into my engine (with the valve closed). He didnt feel it was tight enough (there was NO oil leaking out of it) before I could stop him he reached down an cranked it down as hard as he could. That was a joy to take off!
