Hey there, I just picked up an '86 Bronco 5.0 late last week... The body was in good shape and was essentially told the battery was bad. When I went to look at it, it started once but not a second time, was running 'OK'. I checked the fluids it was leaking some oil and the radiator looked like it was low and had some rusty water in it -basically telling me this thing has been sitting-. Everything in the right taillight wasn't working, back window wouldnt go down either. I took all of this as an opportunity to make a low ball offer which was accepted. It promptly overheated (twice) on the way home which was an adventure without functional hazards. and was spilling water out of the block where there was no longer a freeze plug. Fixed the taillight (bulbs werent screwed in correctly [LOL]), Cleaned up a lot of smaller issues such as the doors not locking, replaced ignition wires. I popped a new freezeplug in at which point another one popped a leak. So I've basically deduced that all the freeze plugs have some rust on them and once pressurized the next weakest one will blow, so I'm going to replace all of them. In the midst of this I've also found a couple of large exhaust leaks and broken valve cover gaskets on both sides.
So now with that all said, Ive done a fair amount of research on the valve cover gasket replacement, and feel like I have a pretty good handle on how to go about that. I'm mostly looking at it as an opportunity to dissemble a lot of the motor and clean things up with some tlc as theres an alarming amount of random missing nuts and bolts. I figure once I have most of this dissembled im going to attack my freeze plug and exhaust leak issue as I should have a lot more room to work. So I guess that my real question is: Am I going to need to yank the motor all the way out or can I just move it a few inches up (and maybe out) and access these freezeplug locations? I havent pulled an engine on a 4x4 before (I really only have experience with small block 350 chevys rwd) so I'm not sure exactly what and where to disconnect if necessary. It looks like the tranny is sealed -no slip yoke- so do I just pop the U joints off to drop the driveshaft? Any help is greatly appreciated, looking forward to being back here a lot since this thing clearly needs a lot of work. Thanks!
