My friend owns a 91 Camry with a 4 cyl. DOHC 3F-SE engine. He was driving down the road and his lower radiator hose came off. He did not hear it at first and says the temp gauge stayed normal. It starts steaming so he pulls off the road and we tow it to my house. We replace the thermostat and put the hose back on securely and it starts and runs but runs hot. I notice something dripping underneath and find oil is blowing out the dipstick tube. I hold my hand over where the oil cap goes and get a lot of air coming out of the valve cover. So I figure the head gasket or head must be busted or worst case the block.
I installed a new head gasket and had the head serviced. I had problems with getting it to start after this but, thanks to this great forum, got it running again (special thanks to Brian R.).
It now starts and runs great! but it still is spitting oil out the dipstick tube. It drips when at idle but blows out on to the exhaust when driving/accelerating. The rubber at the top of the dipstick tube is broken so does not seal good. There should not be oil coming up that far in the dipstick tube... Right?
P.S. - It does not seem to overheat any more.
