I think I'm fawked

If you read my other posts you know that I put a DUI HEI Dizzy inand just when I finished tuning it, I got a clunk from the starter with a little movement of the flywheel. I then took it back apart and cleaned the grounds and everything was working then again I get a clunk with no movement of the flywheel this time.

I take the starter out and it runs fine. Put it back in and Clunk. Take out the dizzy and Clunk.

I think I fawked my engine and I don't even know how. prior to this running smooth, good oil pressure plenty of oil.

Only thing I can think of was the backgiring it was doing while I was getting it going damaged something.

I need some help. If I have a blown engine and I know it would be very expensive, I may be out of the Landcruiser club.

Thanks,

Ken

when you pulled the dizzy, did it have the gear still on it? maybe it came off and jamed up the works(but not siezed the motor)

if you havn't run the motor sense you put the dizzy in, then I can see no way you could seize it.

The Dizzy all came out in one piece. Looked down the hole and everything looks fine.

First off-don't panic. If it hasn't run, it probably isn't seized. Remove all the spark plugs and turn it over by hand (put it in neutral obviously). If that fails, put it in 4th and push it with your hip (the bump) and see if it turns over. If it's seized, that's really weird. Usually you have to get it full of water, or run it with no oil. Myybe your starter solenoid isn't retracting or some other weirdness. Keep us informed.

Pulled the plugs out and tried to move it by hand. Tried to get a breaker bar in there, but can't without removing the radiator and fan belt.

How long did you run it backfiring and popping, Ken? IF it was a long time, and it was because you didn't have your dizzy in far enough to engage the oil pump, well, I guess it is possible to seize the engine that way. But if it wasn't long, that's unlikely. Like Andrew said, do something aggressive to turn over the engine by hand or by pushing the truck in gear. You should be able to turn it that way.

I ran it for 10 minutes max putting together two times I put in the dizzy. It seemed like it was fully seated. I felt down at the base and made sure the flanges were together with no gap. I made sure the shaft was the same length from the flange as the one I removed.

If I took it out and towed it, I'd never get it back in the garage. I have a 35 deg slop to my driveway. I would probably try that on the way to take it somewhere. Not sure where.

Guy on Pirate said swapping a 2F is easy. After this, I would question my abilities.

Maybe it would run if I flipped my Bezel over.

Anyone have recommendations of a good place in the Denver area. A retired guy who does this as a hobby and is not expensive would be great (Yeah like I am going to find someone like that)

I don't know if you saw my question on the other thread, Romer, but did you check for oil pressure after installing dizzy? Other then that I don't see how it could be seized.

You may have just caught a bad tooth on the flywheel that you have never happened to line up to before. Unlikely, but theoretically feasible.
This could be proved/disproved easily, just get the flywheel to turn, doesn't even have to be a complete turn over.

I think at this point doing what you need to, to get to the crank may be necessary. You can fold down the apron, and just pull the radiator out of the support, and leave the support in place. Should not take long.

Yeah, don't worry too much, yet. I speak from experience when I say it takes a LOT of abuse in order for the engine for to seize. When my engine siezed up after a broken head gasket it made a loud, low "DOOOON" sound when the starter tried to turn it. I just kept turning the key and eventually the thing fired up and ran! I drove it about 15 miles (I really had to choice at the time), repeating that same starting proceedure a number of times because it overheated every five minutes. My whole coolant supply ended up in the crankcase and all I had to do was change the oil and headgasket and everything ran just fine afterwards. Point being: the things are very tough and can take a lot of abuse before they break beyond repair.
I don't think you have to worry about valve/piston interference. You aren't running those fancy, high-compression pistons, are you? Either way, I think you would have heard something if that were the case.
I haven't been following you're previous posts, so I'm guessing you've already gone through the simple stuff (ie. charged battery). Is the "clunk" you describe the sound made by the starter engaging? Is the starter drive wheel spinning? Do you have access to a starter cart? If yes, hook it up on the "Fast Start" setting. I'm kinda thinking the starter isn't getting enough juice.
I see Cruiserdrew mentioned turning the engine over by hand, that definately sounds like a good idea. It will give you a good indication as to whether or not things are moving smoothly.
If you're sure the problem isn't the starter then you might want to pull of the inspection cover on the bottom of the bell-housing. I can't really say what to look for, maybe something broke off and is jamming things up(??).
You might also want to take the valve train and the side cover (on the block) off. You can then poke around the lifter holes and make sure the cam is all in one piece.
Like some of the other guys have said, I don't see how you could have seized anything if you didn't run it very long. IMHO it takes a fair amount of work in order to get a 2F to seize.

Just noticed you mentioned some backfiring. Did you have some of the ignition wires crossed or remove either of the timing gears?

Is the truck in gear?

I must have been lucky and put the dizzy in perfect the first time. Started right up no backfire easy to tune and do timing. Then Clunk. Took the dizzy out cleaned up a few grounds and the starter would turn again. This time, I put the dizzy in wrong (phase) and it took me a while to figure it out. Backfired a lot and ended up really flooding it. Figured it out and got it to start. Was running a little rough and was adjusting the dizzy when it died. No loud metal sounds like damage, but next try and clunk.

I think the clunk is the strater engaging but not moving anything. Seemed to work OK on a bench (my garage)with no load.

It is in Nuetral

Did you check the oil pressure guage after you installed the distributor? It is unfortunately fairly common that the distributer doesn't go all the way down and engage the oil pump drive. That will ruin your engine pretty quick. For your sake, I hope that isn't it. The first time I re-installed my distributor, I watched the oil pressure guage like a hawk, just to be sure my engine would be OK.

You still need to turn that motor over, or prove that you can't. Try putting a wrench on the alt pulley nut, tighening the belts fully, and turning the motor over with a breaker bar? I've done it that way before. The alternative is to remove the clutch inspection cover and turn the flywheel by hand. That works very well, just wear leather gloves.

You don't have to push it all the way down your driveway to get the engine to turn a little bit, Ken. Just a few inches in the garage with it in gear should turn the fan and then you'll know it isn't seized.

If the distributor wasn't all the way down and it had low pressure, Is that a complete rebuild? New engine? Just trying to undertsand the worst case.

If the distributor wasn't seated then you would have no oil pressure. That's bad. Probably would take out your bearings, rings and cylinder walls. The head might be OK. Did it knock at all? Since your motor didn't throw a rod through the block, you may still be ok, or you may need a rebuild, but at least you have a complete motor to start with. Why don't you remove the inspection cover, grab the flywheel with both hands, then you'll know. I'm feeling your pain.

Just seemed like knocking from timing being bad. based on what you guys and the folks on Pirate said this is what I will do:

Tomorrow I think i'll take both the starter and battery and have them checked. If they both check out OK, I will pour marvel mystery oil down the cyl's. then Sunday pull it with a tow strap out of the garage in Reverse about 4 or 5 feet. Just enough so I can push it back in.

If that doesn't work then I guess I'll be researching engine swaps.

I'll post what I find out.

Thanks for being there. It's easier having you guys to bounce things off of.

Ken

If you take out your plugs and use 4th gear you won't need much force to turn it over. Mine turned over just leaning on it during a tune-up once when I forgot to set the E-brake. 8)

Well, starter checked out Battery checked out. Tried mobving it in 4th gear by hand and no go. Tried putting it in reverse and pulling it backwards with my GMC and no movement. The FJ moved 2 feet, but the tires and fly wheel did not move, it was dragged.

I no longer think I'm fawked. I Know it!!!!!!!!

I guess I need to decide one of the following:
1) Rebuild
2) Replace
3) Put V8 or other engine
4) Sell it and cut the bleeding. Thats what the wife wants to do.

Based on my skills of replacing the dizzy making it dead, I don't have any confidance that I can replace or rebuild myself.

Too bad, the DUI Dizzy was my birthday present.
