Last time i Had a full rebuild dont and upgraded my cam to a 224/228 .581 .588 110lsa with a 3800 circle D stall. Only about 1700 miles on it since all that was done and it started making a loud knocking noise about 3000+ rpms under normal driving, and on the highway with cruise on about 60 the oil pressure would fluctuate from about 25-45 psi. And ideas? And Yes there was metal shavings in the oil. Hopefully the shop that built it will warranty it, they have it now, they said they would but Im sure they are looking for anything that may not be their fault. They are suppose to call me tomorrow and let me know.

Did you install it or them?

Also, was the filter dented any?

sounds like it spun or is spinning a few bearings..more than likely rods..

They did everything but put the motor in. I put the motor in and intake, and all that stuff. It ran great for 1700 miles. Filter as in oil filter? No.

oil pump not centerd on crank...... would cause all of above..... it is very important on these motors to center the pump.... hope it is something simple like this.... but the bad part is if there was metal in oil.... all bearings need be replaced.... cam included... and hope it didnt scar up crank.... Good luck.

The shop said it had a warranty if it was anything they did. And they put a new oil pump on it. I had a sealed long block and just dropped it in the truck. So it cant be anything I did.

yep, hope they stand behind it.....

yep very costly...some of these shops just dont know much about these ls motors...not like a sbc.

Should hear from them today about what happened and if its going to cost me. Wish me luck!

Good Luck. If they don't make it right get a long block from proheads.com you wont have any problems with a motor from them.

Well I still have not heard from them. They said they were going to tear it down wednesday morning and see what the problem was. So hopefully it was something with the original build they did and I'll get a call saying to come pick the motor up. He said he was going to call if it was going to cost me some money... keeping my fingers crossed

Well talked to the machine shop. They said its the number 8 rod bearing and all the others show signs of wear. They said it looks like it could be from detonation. Any thoughts?

1700 miles should not show any wear. I am leaning toward builder error.

Even if I was having detonation?

What did all the other bearings look like? I'd go up there and inspect and take all the parts to get a second opinion.

A while back, we had this 6L GTO engine built, took three times and two different shops. In the end, it still wasn't right, I told the customer "if you buy a new block and crank and it doesn't fix it, I'll pay for it"
Ended up being some freak issue with the block I guess, cause the new block and crank fixed the oiling issues. This engine kept eating up crank and rod bearings around 1000miles. Indicator was low oil pressure.
Probably the shops fault cause both of them should have caught whatever was wrong, but sometimes it's just better to...

I'm not saying your truck isn't strong, but at that power level, I really doubt you tore your engine up with detonation. Wheatley knows where the timing needs to be, there is no way that tune would kill your engine with detonation issues.

I would check the other bearings and make sure it's not an oiling issue, crank walking, etc.

Good luck,

I am going to go up there probably tomorrow and get some pics for yall and post them here. Thanks for the advice. I just can't keep spending to rebuild it over and over again. Somehow gotta get it right this time.

Sounds like they are looking for a out. Even before I read nelsons post, I was thinking after you talked about detonation, that Charlie knows what can and can't be done..

John

Damnit ,Good Luck.

One guy in town that I talked to asked me who degreed the cam in my truck. Well all the other cam swaps I have done all we did was stick in the cam and line up the dots on the sprockets. He told me you had to degree a cam when installed. I am a little lost here so can someone help me out?

degree'n the cam is not necessary; i'm not saying don't do it, or it's not better, but hundreds of us install cams straight up and never check'em and they all work out just fine.

Here is a pic of cylinder 1 upper rod bearing

Here is a pic of cylinder 2 lower rod bearing

And just another one I took a pic of

Over all 4 or 5 bearing looked like the second picture. All the others looked good

WOW! Thats terrible.

They are of course gonna say not their fault, yada yada cause that would cost them money.

Looks like no oil.

Or trash from the original build they did. When they didn't clean the oil gallys good or something?

Definately not detonation. Looks like a oiling issue..

Any other thoughts? Has anyone seen anything like this? On a motor with only 1700 miles

Lack of oil for sure

So that should go against the original build then. And they should stand behind their word and warranty it I would think.

yeah, that looks like oil starvation. I bet the oil pump is trashed, too. If they don't know the proper procedure for centering the oil pump you can gaurantee it's their issue.

hope you are not totally screwed on this. If they don't redo the engine I would buy one from LKQ or get a rebuild from proheads.com. My stock lq9 from lkq is doing great. Just a cam swap and that is it. oh and 8psi.

Did i get lucky cuz I don"t remember having to center my oil pump when i did my cam swap?

Looked on proheads.com, didnt see any info on rebuids, what are they going for? Im getting up in miles on mine and need to start planning ahead.

I think you have to call them. Proheads that is. LKQ can be found on the net. I am not sure what lq9s are going for now.

Call them and speak to Rex. He is an employee there who does motor builds on his own.

They/he built Caseys motor that he did a ton of blasts down the 1320 and spent hours on a dyno. Tons and tons of hours. Motor was nearly flawless when he pulled it apart after deciding to go to a larger motor. If I were going to have a motor built he would be the one to do it.

Rex does great work. He built ecld_07's motor as well.
