i wanted to make sure that i have a head gasket failure this is what i,ve done. i searched the entire block and head gskt nothing there. i pressure tested the system to 18 lbs slight leak in a heater hose fixed that. there is no coolant in the oil. my nose doesnt work that good these days so i cant smell any coolant from the exhaust. no white smoke from exhaust i pulled the plugs today 1 was kinda black and the rest were white? i add a cup or so of coolant a day, so where is it going??? and lastly a head gskt kit who do you buy from. i did this job 4 years ago on a different van using a felpro kit that the machine shop sold me it worked fine. but i keep reading use only toyota. my goal is to try n nurse it through the winter cuz i dont have a garage and i need the van for my heating service. any thoughts? thanx in advance joe g
