thats why i want to take to another rod out, to should keep it ballanced, i think.???? so if i have the number 9 out i should take the number 8 off?

and this truck has 270,000 miles. i have no idea if the tranny is any good so i dont want to go out and buy a new motor and just have the tranny be crap.

so i want to get it to run and see if its ok and then i might rebuild what would i be looking at for the cost of a motor? new or used?

also would it be posible to just replace the #9 cylinder and piston?

but on selling the truck i guess mabe, it will have a bad transfercase that the 4x4 dont work, the bed is really good: has a few small dents, and has some scratches, has a small place where the paint is bubbling on the wheel well but its not bad: the rest of the truck the one fender is starting to rust no rust holes yet, and the rockers are rusted, and the bottom of the doors on the inside are getting bad.

I guess i might be interested in selling if you come and get it, it after i get what i need off of it. Im in the South Bend, IN area.

 

Erm. Taking rods out exposes the oiling ports to air. I.E. no oil pressure beyond those journals. It would run for a few minutes, maybe.. and then start munching up parts.

You can replace the pistons, and rods, but, what do the cylinders look like? Have they been beaten to crap by metal objects flailing about? Any holes? What does the journal look like?

 

Do you want to sell some parts off it before you junk it? If so, let me know. I just need some small stuff that could be shipped cheap.

 

i think all the cylinders and pistons are fine except for the one that broke which is the number 9. the cylinder wall is not in the greatest shape. no holes, but scratched up pretty good.

i dont understand what you mean about taking the rods out it would have no oil pressure?

and what is the journals?

also is it possible to replace just the one piston and rod? and proble the cylinder needs to be bored out. i really dont want to mess around pulling the engine. so is it doable with leaving the engine in the truck?

 

the clearnce between the rod and crank is what gives the motor oil pressure. No piston I one hole will let oil out exhaust. To be honest there is no good idea in this. My best advice, part out what's good so the decent or rebuildable parts will be salvaged, junk the rest. Or sell whole truck for junk price and be out of it. Because the idea of running a v10 on 8 cylinders tells me that haven't worked on very many cars. Please don't tear up another v10. The journal is the part wherethe rod rides on the crank, the journals get in to bad of shape new crank. Bore an engine in the vehicle, nope. Bare block is the only way, could sleeve it if overbore doesn't get the scratches out. Then you probably could benefit from decking it and line honing. The motor needs to be torn apart, inspected and proper machine to fix and then rebuild from there.

 

ok i understand what you mean about the oil pressure thing. but any ways i have not torn the motor apart, all i have done is take the oil pan off and took off the cylinder number 9 conecting rod out, the broken piston is jamed in the cylinder and wont come out.

but my question is with one rod off will it be ballanced? or if i take one off the number 8 as said, will that ballance it? or will not be ballanced right no matter what i do????


and for the oil journals i could always weld them shut.

 

with one rod off, it will not be balanced. With two off.... anyones guess. Not really relevant though, as you can NOT run the engine that way. You will burn it up in a few short minutes, if that long.

The way the oiling system works is, there are passages drilled thru the crankshaft, for oil to get to the various parts. Rod and Main bearings being what we are concerned with here. What keeps the system pressurized is the tight clearances between the rod bearings/crank, and main bearings/crank. If you pull off a rod, there is no longer any restriction there, therefore, the oil travels the path of least resistance, and runs right out thru the open hole. You will have ZERO oil pressure. It will trash the rest of the motor in VERY short order.

The only fix for that motor is a rebuild. Not gonna happen in the truck. As it sits, it is a very heavy paperweight. Some parts are still good, run it without oil pressure, and none of the parts will be any good.
