Okay, got it opened up. Had to go through 3 cameras to get this picture. My Nikon Coolpix croaked, I took yesterday's on my old-old trusty Kodak easy share 9but it's batteries died) so I stole the wife's Nikon (gotta get used to it :evil:). First pic shows opened up.
There has been some talk here about failed thrust bearings. Hadn't seen it first hand before so I'll try to document it for everybody. Pic 2 shows where the crank counter weight has contacted the block and cap. There were pieces of the thrust washer in the pan (block after I rolled it over). From what I understand, this engine will be junk now :cry:. If that's the case, I will go back to the "in frame overhaul" plan, but I will install the '93 pistons and rods, and use the #6 casting head if it checks out okay.

Hard to see any damage in the pictures Dennis , if it's not torn up though I would imagine that you could rebuild it ...
need to get the crank out and look at the bearing ride surface and see what the block looks like ... Is there an oversized thrust bearing available ??

Installing valve stem seals, valves and springs. This head was in real good shape. Valves good and tight in the guides, good seats and faces. I disassembled it and cleaned everything up, then I lapped all the valves and seats. Cleaned it again. My gasket set did not come with valve stem seals (? :roll:), but it turns out it is a set (Felpro) designed to go with a remanufactured engine (yet it has a head gasket). I was able to order a set of Fepro stem seals from Autozone (about 21.00)
This is the way I did it. I don't have a spring compressor for overhead valves (have 2 different ones for flat heads), so I made an adapter to use with a C clamp (see picture)
Note rack / block to hold valves and use of egg carton to keep springs, keepers together. It is important to keep everything together and reassemble where it came from.
I like the felpro seals because they have a nice retainer spring that snaps into the groove on the valve guides.

This is fascinating!! So yet another rookie question...... the lapping process in essence fills in any imperfections in surfaces of the valves and seats, right?

Actually, the opposite. The lapping compound is an abrasive which cuts the surfaces to a better match for each other. It is typically done with a suction cup attached to a stick and rolled back and forth between your hands (like starting a fire?) Dennis

You are sure you got FelPro seals, right? Twice now I have gotten seals that are too tall and only realized after they got chewed up.

As for lapping, I assume there is a reason that I shouldn't do this, but I tape up the top of the valve stem to protect it and then chuck it up a hand drill. Fwd, rev, fwd, rev, a few times seemed easier than the fire-starter stick technique. In theory I suppose you could over do it this way or nick or bend the valves...

Seals are same size as ones that came off it. I have lapped the valves with a drill as well (but didn't use tape). My "small engine" cup was barely big enough to clear the depressions in the valves (did use the drill a bit). Overall, I'm happy with the results.
Forgot to mention that this head had come off the engine with the blown head gasket, so it had been exposed to some moisture. This was one reason I wanted to tear it down and clean it and lapped to remove any stains / beginning of rust between valves and seats. Also to thoroughly insect valves and seats.
Overall goal: 1 stop excessive oil consumption. 2 hopefully, better gas mileage, 3 maybe a little more pep, but with the lightness of the pickup, even the Spacecab, it does better than a 2.6 in a Trooper.

Finally! Took a few extra days with Memorial Day to make a 5 day weekend and finally do the re-ring job to my Spacecab. Originally, I was going to do this "in frame" (without pulling the engine), but I decided to go ahead and pull the engine and do it on the stand. Forgot about all the fun stuff to be removed :roll:. Actually got oil and coolant drained Friday evening, but "other stuff" ( :x) took up Saturday and Sunday. Hot and extremely humid today. First surprise was the cracked exhaust manifold :shock:
OH, BTW: Previously my camera had died. Got a replacement, then my Laptop pooped. Got a solid state hard drive put in it, but had to reload everything. First picture post since then. Dennis

1:30 - Engine is out, clutch / flywheel removed. Definitely not doing this like the "5 guy", but I'm older than he is. Also ost about 1/2 hour to an important phone call, and another hour because the engine wouldn't clear the radiator core support (had lift chain too long)

I was worried about how it would look inside. Overall, pretty good. Big concern was for cylinder scoring or ridges. All okay. Now here's the problem: when I went to clean the pistons and use them to position and measure ring gap - THEY ARE .020 oversize!!!!! this surprises me as this engine only had about 130K when I bought it. That seems like low mileage to have already had an overbore.
Now the real rub. I was planning on using the 1993 updated pistons - but they are standard. I want to update to the new head (and pistons), but pulling my hair out so far on where to find pistons (Rockauto seems to list, but not oversize). Some on ebay, but not sure I trust them. Any Ideas????

ordered a set of .020 oversize late style pistons and rings from Jerry last night. While waiting, I'm keeping busy doing a few clean up things. Today, I decided to see if I could pull the wrist pins myself (wrist pins "float" in the pistons and are press fit in the rods). There are a number of "how to" videos on the internet. Some are scary, some are almost funny, a few have decent information. Many involve using a propane torch to heat the small end of the rod ( a standard practice, but be careful!)
I figured out my own way. I started with one of the pistons and rods from the Amigo engine (spares). First two methods resulted in nicking the rod (junk now) even though I had it wrapped in a rag in the vise (no more rod in the vice stuff :oops:). Second method damaged the piston (huge thick flat washer against side of piston to attempt to pull the pin - left 2 small flat spots on side of piston). Finally made a special spacer to fit in the "flat" spot on the side of the piston where the pin goes. Next piston worked like a charm (one of my keeper rods - don't care about my old style pistons). 3rd try saw the failure of one of my spacers (short section of pipe nipple) which damaged another piston. Got a stronger spacer and the rest went smooth.

pistons and rods 003.JPG


Note: each piston has a small "pip" on one side. The pips go to the front of the engine. Also note that 2 of the rods are smooth in the center and 2 say "Isuzu" (actually ALL do). The "Isuzu" faces the rear of the engine. There is an oil jet on one side of each rod and if you put them in backwards, it won't oil properly. Dennis

I think I tried to press out a wrist pin on Dustin's engine build but man are they in the rods right (I tried using oak as a cradle) so I just let the shop do it all ... You don't even have a bike now do you ?

Nice work Dennis! I've been getting lured out into the wild for one trip or another, the only progress I've made on my engine project is whacking the original freeze plugs out. :roll: I hope things continue to progress well for you!!

Brad: as I mentioned, I had 2 "failures" before I dialed in the pin pulling process. First was trying to heat the end of the rod with rod clamped in a vise (cushioned with a rag wrapped around it several x). No good. Second was using the big washer which A) left flat spots on the piston, and then B) pulled the threads off the bolt. I ended up using a 1/2 x (maybe) 6" grade 8 bolt and my various spacers with the special made spacer. Still debating trying to install pins. Problem with taking them to a shop will be first getting them there (no shops in my neck of the woods - all across town), and second how many days of extra down time waiting on the shop (would be at least one day to get off work, get wife's car, go to shop, drop pistons, then 1-2 days to repeat process when done).
I do still have my Honda 125, which is fine for getting me to work (5 miles) and basic scooting around, but it won't go on the interstate. It's redline is 60mph, and 1 time I did take a short 1 mile hop from an entrance ramp to the next exit and it was super squirrely. Won't try that again. Still waiting on pistons.
John, making slow progress. I did look like my block has brass freeze plugs in it. Mu undersize rod bearings did arrive last night (Clevite bearings). Dennis

Today's score:
Mounted 2 pistons to rods. Went much easier than taking the old ones off, maybe because I put the wrist pins in the freezer first. Hardest part was getting the wrist pins centered in the piston bores.
Measured old ring gaps of all cylinders. Specs are: Top: .0118-.01177 ; second:.0236-.0283 ; Oil rails: .0079-.0276
Findings: #1 T: .030, 2: .020, oil: .030
#2 T: .033, 2:.017, oil: .035 / .050
#3 T: .028, 2: .020, oil: .040 / .038
#4 T: .036, 2: .020, oil: .042 / .032
Makes me wonder if the top and second rings had been put in the wrong places?
Go #1 and #2 cylinders fitted for rings, pistons, rings, bearings installed in those two. #3 Main cap pulled, thrust washers replaced, end play measured and within specs.
Hopefully, bact to it tomorrow afternoon. Dennis

Yes, measured about 3/4" from the top, using an old piston to evenly push them down into the bore. No new progress yesterday, hopefully after work today.
