Mods, if this is the wrong forum please move the thread. This build has less than 10,000 miles on it, not built by me. The motor spun a rod bearing at about 10K of daily driver use. The block had about 117K when it was built. It's a '98 LS1 (yes aluminum block) honed 347 with 10.1 forged weiseco pistons, forged rods, polished gm crank, ported LS1 heads, hardened push rods, new springs and rockers, custom comp spec'd turbo cam (560ish lift), and new LS7 lifters. What would it be worth as is? Just trying to get a ball park figure to see if it is worth my while to repair and sell or sell as is. Thanks

About $10 shipped to my door. lol j/k. I would pull the pan and inspect the crank and rods. Maybe you can just get the crank turned and replace the main and rod bearings. It shouldn't cost that much to get it turned and you can sell it for alot more.

Sounds like you have a good amount of money into it already.Like stated above i think you are better off fixing it or at least tear it down to see how bad it is.I don't think you would get what its worth if you sold it as is.My .02

Yeah, I guess I'll try this approach first, my car is down for the moment with this motor and the labor that it would cost to fix it is insane. I'm better off putting a new built short block in there and try to sell this current one to offset some of the cost. Thanks for the advice.

If anyone else has an estimate for what this LS1 is worth, please post.

In its' current state it's worth what a damaged engine is worth to somebody. Buyers will wonder what else is wrong w/ it. Where are you located?

South FL I would rather get rid of it and start with a new iron short block or a low mileage 2001+LQ4, I'm already turbo and don't really care about the extra 100lbs it will add. If I can't get rid of it for a decent amount, I'll try to repair later down the line after I have a new motor in the car.

As is I wouldn't pay more than ~$300 to 400 max...because who knows what you'll find on tear down on an unknown engine...it might be just a bearing or it might be the whole motor is trashed. However, with all the stuff you've put into it, I'd tear it down and see about fixing it, if it was my engine instead of trying to sell it as is.

If your making the buyer fix it as is, also it is a 98 block vs. something newer, I wouldnt pay more then 250.00 just because even if the hard parts spec out, it still needs a rebuild top to bottom.

in its current state no more then a stock ls1 with a spun bearing. as said before you dont know what you are getting when u buy a damaged motor. so all the good parts you have in it would be a lose for you or a bonus for the buyer depending on if they are all reusable. i say 300-400.

Thanks for all of your input. Yea, you guys have me convinced to try and fix it before even trying to sell it. The motor just has a slight tick, perfect oil pressure and drives fine just does not put down the power. I only drove it 5 miles to get home after it happened and the car was driving fine under partial throttle. The car has not been driven since, only turned on for the engine builder to inspect. I'm going to save for a new built short block and when I have it in my car and running again, I will work on the LS1 at my own pace. Just sucks to see a turbo V8 sitting there knowing I can't open it up. Going into boost has become an addiction...

well i kept my crank and got about 20 bucks scrap out of the bare block pistons and rods...mine didnt spin the bearing...oil starvation got it and put the rod bearings in brass and a couple of them into the crank...in the process it effed up 3 of the cylinders so my block was junk....

i just realised its a 98...the oil gallies in the 98 blocks= crap...how high was you spinning the motor...mine also had a light rattle and tore it down to find the worst...

It was tuned to 6.5K limit on what I believe is a baby turbo cam 222/224 comp with about .56X-ish lift. The more I hear about this happening to people, the more I just want to buy a new forged short block. I'm just going to save for it, a new 370 built forged iron block seems like the least expensive route, for a decent platform. When I get a motor in the car, I'm going to tear down this LS1 on my own (first LS1 tear down) and see if I can salvage it and maybe turn it into a side project. Worst case scenario, it gets scrapped.

Are you sure it is a spun bearing? That usually makes the oil pressure drop.

omore001

iTrader: (1)

I know a spun bearing usually means low oil pressure or even none at all, but when it happened, I just caught it and did not ride for more than a minute after it began. It's possibly not yet reached a level of catastrophic failure, ie: great oil pressure, I cranked it 2 days ago and cold start pressure came up to almost 60psi instantly.The block has not been stripped bare yet, so I can't justify that it is just a bearing, but this is what I have been told by an LS1 engine builder/tuner who knows his stuff and has been doing this for some time, when we had the motor torn down to the lifters. The car really does drive fine, but wont rev as hard or as fast as or as high as it used to, wont hold any boost either, the boost reads 0 lbs WOT.

spun bearing shouldn't have anything to do with boost

omore001

iTrader: (1)

Spun bearing can prevent a motor from going into boost because it's not allowing my motor rev high enough to get it into boost.

It's worth what someone wants to pay for it.

With all that you have in it, it may be wiser to re-build it.
