I purchased my 1984 b2000 for $700. It' s a five speed with a late Courier grill conversion. My father drove it home. I'll upload pics of it in a bit. It needs some work.
So far, I've replaced the carpet and seats with some I found at pullapart in Bham, repainted the grill and knocked out a few dents in the passenger front fender. New air filter, cap, rotor, plug wires and sparkplugs.
It runs, albeit rough. The carb is great, vacuum lines notwithstanding. All emission have been deleted, so I'm a little lost in finding out where the vacuum lines go. I don't believe I'm too far off though.
Diagnosed a pretty bad misfire on cylinder #3 by removing the wires while the engine was running. In fact, cyl 3 does not fire at all. The person I bought the truck from said that it had a rebuild about 30,000 miles ago?
Neewayz, I checked my valve clearances. The rockers for #3 (esp the exhaust) where tight (as in no clearance). Went through and set the lash to .012" and heard a lot of clatter. Engine seemed to run smoother though. Re-adjusted lash to 0.009" and that got rid of the clatter.
Compression #'s aren't that great. I think it was 110, 100, 0, 100. Cylinder number 3 with a teaspoon of oil is at around 30 psi.
Good stuffs.
So, I did a leakdown test (modified compression tester hose without the schrader valve thing) on the problem cylinder. I'm 100% positive I have a burnt exhaust valve, because that's all I heard (a crap ton of air rushing through the exhaust manifold/pipe).
Now I am debating as to whether I should go ahead and get a valve job done on the head or if I should lap the valves. I think I'll be able to decide on that once I've removed the head.
Bought me a Ford Courier Hayne's book though (was cheaper than the b2000's counterpart).
