Yep! I cannot believe it... Does anyone know if the timing chain cavity leads directly to the oil pan? If a bolt one of the two front ones that tie the head to the timing cover were to fall into this cavity, will it drop to the pan or sit in with the lower gear? I am just about to grab the 10 gage and put this P.O.S out of my misery. If anyone could let me know I would appreciate it. Thanks

it does not go in the oil pan

Any ideas about how to go about retrieving the bolt? I am really stuck here. Any advise you may have would be appreciated. Thanks

telescoping magnet... but with a big magnet...

My guess too!!!! Good luck!!!!!

I though it does go to the oil pan. But I caould be wrong.

Thanks for the ideas! I'll try a telescoping magnet see if I can get to it. I have not worked on a LUV before but, the idea that the timing chain case does not go all the way through to the oil pan seems odd. Any way, I post later once I take another look at it! Thanks

I thought it went to the oil pan too.

it definitely does go through to the oil pan. i'm rebuilding mine right now and as soon as i pulled the oil pan, that bottom sprocket was staring me right in the face.

got another one!!! 1980 4x4 mikado sport. rusty beater for now...

that was my thought too! i just finished rebuilding my engine and that cavity definately does go through! but 800xl will know better than me.

Maybe I should have clarified my answer, I meant the bolt would not or should not. when I rebuilt mine I dropped the bolt 3 time trying to get it in there and it always hung up on the chain or tensioner never went to the oil pan, hade to use pliers and a magnet to get it out each time, I was under the impression with my experience that it would not make its way down there, sorry for the confusion

I've been looking at the insides of Isuzu 4ZD1 motors too much lately to remember for sure. I do believe it gets really tight in there right around the gear so chances are good the bolt would not make it all the way down into the pan. I have about a half dozen different magnetic grabbers just for this sort of stuff. I've never had it happen but I'd rather have the tools handy if they are needed. Most parts stores carry a couple at around $5, just get one with a telescoping handle and go fishing. It will either come out, or it did make it all the way down and its gone until you pull the pan. I'd be the type to just leave it there and hope for the best, like it will just drop out at the next oil change.

I want to thank everyone for their input and help. I am going with the bolt went all the way through to the oil pan. I cannot see the bolt and have tried several different magnets to retrieve the bolt. Hopefully the LUV will be finished tonight! I will let everyone know if the timing chain does it's best impression of a hand grenade or if the bolt will remain at the bottom of the oil pan fulfilling it's new destiny (Keeping the bottom of the pan clean!) Thank God bolts don't float!

Since your going that route, how about putting a magnet on the bottom of the oil pan (on the outside), so the bolt will hopefully go to the magnet and stay there. That way it can't bounce or move around and get into the crank or rods.

That is a good idea, I've got a few magnets laying around. I think it will work until I get suckered into rebuilding the engine. The way I look at it is that if the bolt causes problems and blows the engine I will not ever have to rebuild it. Until that day comes the old truck might just luck out and survive long enough to warrant a rebuild. I didn't get it finished last night so this morning I'll be wrenching away till it's done. I will post the results later.

If the oil pan is empty and you can move the bolt with a magnet, why not pull it over to the drain hole and see if it will come out. If not and you leave it there you could magnetize the oil pan drain plug and it might stay. Personally I would not do that. If you are driving along at a high or low rate of speed and it locks up the back wheels, you are asking for a accident.

I want to be different like everybody else.

That one bolt alone would not lock up the motor, at least not directly. It would have to jump up and get caught somewhere along the crankshaft between the crank and the block, both of which are much more solid that that little bolt.

Absolute worst case, it gets ate and wedges hard enough to damage the crank or a rod and causes the motor to throw a rod. Now that could lock up the motor, but usually not immediately. Not before beating up the block with the broken stub of a rod, knocking a hole in the side, and spewing metal fragments and oil all over under the hood. If it goes it would be exciting, but not in the same way that say, wedging a chunk of spider gear between the ring and pinion in the rearend would be.

The magnet idea is your best bet, though on a steel pan it might not let it move around very well. I honestly don't think it would bounce around enough to cause much carnage, and would eventually just plop out in an oil change. Not that I'd drop a bolt in my motor to prove it, but I just don't think it would be that prone to jumping around.

O.K I've been driving the luv for about two weeks now and have had no problems yet with the bolt in the oil pan. However, I cannot seem to get the truck to idle smoothly. When giving it gas the "Miss" seems to disappear just to return while at idle. Cap, rotor, plugs, wires, points and condenser have all been replaced. The carburetor was rebuilt by my brother-in-law (wasn't going to touch it myself!) so i don't think that it's a problem!??? So any other ideas besides the carburetor would be helpful! Thanks everyone!

Something wrong with your timing.

The chain tensioner is letting your timing adjust/float/vary at revs. Possibly something to do with the timing chain chewing up a bolt. lol.

Just having a dig, but it could be worth cheking out.
