The saga continues
Update time for the BII port-a-truck
Finally was able to get an afternoon to work with the ol' beast. Found a large number of severe screwups by the PO in the process.
For example? Who forgets to tighten down the lower alternator bolt? The stinker is at least 5" long, kinda hard to miss.
Most of the bracket bolts? Finger tight?!? And the ones that are a PITA to get to? Must have been tightened by the Hulk!
Anywho... Got the alternator sitting in the back of the truck, A/C compressor is resting on the ledge above the radiator a few inches from the battery.
Managed to get the upper intake off, and I'd love to shove that rear bolt that holds the A/C line and the transmission line someplace the designer would not enjoy.
I did notice the PVC line was caked and cracked badly where it attaches under the intake--Same for the breather tube--Must be vacuum leak city. It's on the list to replace with new--along with all the belts and hoses. (Upper hose feels like foam rubber) And the intake air holes? Black with carbon deposits. Gonna have a party with the hose and the B-12 to clean all that junk out. I figure I'll have to pull all the injectors as well, and see if I can carefully spray clean the nozzles. I've not pulled the injectors yet--but considering how much buildup of carbon is in the intake? Fair bet the spray jets are caked as well. (old trick, B-12 and a very soft brush should at least get the ends cleaned up--can't afford to replace all the injectors)
I think it's also a safe bet, considering this ol' girl must have been running crazy rich to create that much carbon? The cat's are probably almost plugged up. And it's also a safe bet the air bypass is not functioning either, as I started it up pretty well---but I had my foot holding the throttle open slightly. (something the air bypass is supposed to do on its own)
Going to drop the coolent on Sunday morning and pull the intake and heads to see what's going on. I'm already mentally ready for a severe cleaning job for what ever waits for me under the intake.....One thing is 100% sure-- The last owner didn't give a turkey about maintenance.
Side bar question however--What's the deal on the disty? Looks like there is only a few inches to remove it?! Just how long is that shaft?

From: Rhode Island
On my 2.9 ranger, which sat for about 4 years. Started it up and ran like crap, after messing with it for a while, I got it fire on at least 5 cylinders. Took plenum off (I don't have AC, so it was fairly easy), took the fuel rail off, and pulled the injectors. Every last one of them had thick oily carbon gunk all over them. My guess from the breather and EGR. Ran much better after I cleaned them.

Well...made a huge dent in the ol' beast today.
Entire intake manifold is out, disty is out (I'd love to kick the idiot that put that retaining bolt where they did..)
Exhaust manifold...Good lord 'n butter. Only two bolts came out on their own. The rest? Snap City.
Managed to get the left head off before calling it quits for the day. Real pain in the rear end considering we had to pry the exhaust manifold away from the cylinder head to pull it off the engine. The Right side should come out easier due to the manifold being able to swing further out of the way with the left head off.
Examined what we had so far. I can not see any clear signs of cracking on the left head. However the carbon build up on two of the pistons, and matching exhaust ports is slightly discolored? Darker then #1 (or #4...front left cy.) The head gasket does not show any clear signs of being leaky. I'd expect more clear signs of coolant leakage.
Oh well.... We will pull the right head off in a couple of days and see what turns up then. In the mean while I dumped some clean oil into the exposed cylinders and whipped it around to prevent it from getting rust damage. (Ok, made a mess when I did LOL... Then again I do have to clean the mating surfaces, so oil on 'em I'm not worried about)
We left the fuel rail on the intake for the time being. What I'll probably do while waiting for the funds to finish this wing-ding? Is bring the intake back here, pull the rail off along with the injectors and give them a good bath. Given how much carbon crap is built up in the intake? They are probably gunked up. (don't even ask about the disty cap and rotor...Factory from the looks of it. First time I've ever found the internal contacts burnt 1/8" deep.)
S-
(yeah, before anyone mentions it? We tried to remove the "Y" pipe from the manifolds to make life easier--After a 2' breaker bar and an impact wrench? They are fused to the manifolds)
