My son and I fixed up a 1979 Brat EA71, four speed dual range. Looks great inside and out...however it is a leaking fool. We know this BRAT sat for at least 7 years before we bought it. Who knows how long it say before that. We fixed her up, changed all the fluids and hit the road. Now the trans is leaking and the rear main is leaking. I noticed last week the oil was milky and foamy (head gasket maybe). I told my wife this was a father son project for him to learn some stuff, which he has. I'm fairy handy and would also have some resources if needed.
Someone tell me we can pull the motor, replace the seals and head gaskets. Thought we should replace seals in the transmission while we at it. Might as well put a new clutch in also since we're there.
The leaking oil is coming out right in the back of the oil pan, but I'm pretty sure it is not the oil pan. It also leaks much faster when the truck in running, like the crankcase is building up pressure and forcing the oil out the rear seal. Could this be a sign of a blown head gasket? I have replaced the PVC valve. We put a weber on it with the valve cover hoses coming together in a T and then going to the intake and air cleaner. Those hoses all appear milky and foamy also.
Here is another clue. I can see no antifreeze leaking or on the garage floor, however it is going somewhere and even after the truck sits for several days, when I open the radiator it sucks air in, like the radiator has negative pressure.
I'm looking for someone to say "GO FOR IT, buy these parts and get after it." Any advise on gasket kits, seals or clutch?
I've got a Chilton book and a How to keep your Subaru alive book.
