Engine Saga...you'll like this


Recommended Posts

Ok guys, some of you have seen my posts about how I paid to have an engine built...what a mistake. I took it back out when my trans went south and tore the engine down. What I found is shocking to say the least. I found a loose O-ring under one of the valve covers...dosen't even belong to the engine. The cam gear was held on with oil pan bolts. The bolts holding the cam retainer plate were ground down oil pan bolts. The lifters were not morels and looked more worn than my 55K mile ones...even the wheels have deep scratches in them. The rod bearings have heavy dirt scratches in them and several are showing copper, now my crank needs turned. Wait it gets better here is a list of the piston clearance for the $650 Mahle pistons which we determined by measuring the piston diameters and subtracting them from the bore diameters which we measured with a dial bore gauge...btw MAHLE SPECIFIES .0025-.003.

#1 .0075

#2 .01

#3 .0069

#4 .0076

#5 .0083

#6 .0072

#7 .0071

Gee I wonder why I had a lot of piston slap????? You'll love this, when I took the shortblock back to the builder he said he did nothing wrong, everything was correct. Hell, even the hone on the cylinders was all dicked up...looked like a piece of metal was stuck in the hone and made some crazy scratches on the bores. I have to get some good pics tomorrow. I am at my wits end, I'm so angry about all of this...and this clown refuses to give me any money back because he thinks he's the god of LS1's. He even told me my pistons were blck because I didn't know how to tune, not because of the oil burning. Well I had a good comeback, I said :I'm not a lazy IFR tweaker like you, I tune the VE tables like you're supposed to" Anyhow I had to rant a little.

Yeah, answer me this...Are digital pictures admissable as evidence in court? I guess I'll have to get a regular camera and take pics. The sad thing about all of this is that if I didn't know anything about cars or engines then I would be really screwed. I am pretty pissed at me for letting myself get F'd like this. Did I forget to mention that I have a recipt that says...Removed CATS and installed test pipe? I found out that removing the cats is illegal, something like a $10k fine. All I can say is it isn't over yet.

CALM DOWN. Yes that is bad bad bad, and I'd hit that f'cker right in the pocket book. Digital photos are admissible, just have them printed on high-quality stock for presentation. When the photos are combined with new rebuild estimates they will hold as credible.

 

Looks like you're going 40-over. :nonod:

 

I know you are mad and you have every right to be, but you are still looking at this kinda wrong. Don't let the comment on the cats buffalo you, this is all a CONTRACTUAL MATTER, don't take the guy to court because he screwed-up your engine (a personal reason), you take him to court because he did not hold up his end of the contract (a business/legal reason). This is a critical point here, you made a deal with him - you promised to pay him $$$, and he promised to deliver a engine built to an agreed set of specs (reflected on the invoice). As far as anyone else is concerned you might have just wanted to display the new motor on an engine stand the rest of your life, or race it, or drive it, or throw it off a cliff but no matter what the intended use was going to be does not change the fact that the builder agreed to fulfill his end of the contract whether you have cats on the truck or not. First it's nobody else's business, and second it's just not material to the contractual matter at hand.

 

I would suggest a different kind of intimidation:

 

Go back down there monday, with a copy of the invoice in hand. I would draw him out by offering an apology for loosing your temper and calling him an IFR tweaker, and that all you wish to do is resolve the issue between you. Tell him that you always make good on your promises, and that you expect nothing less than everyone else do the same. When he begins static again (he sounds like the kid of person that will push a bad position) you tell him very calmly again that you made good on your end (you paid him up-front) and that you expect the same from him. If he balks a second time, calmly tell him "you do not understand your position here, I'm not asking you to finish your end of this deal; I'm telling you that I can make you - your job is not done yet" and leave.

 

Because you can. When you appear in front of a judge, the matter is very simple - a contract dispute where you obviously held up your end, and the plaintiff (for whatever reason) did not. He promised you an engine - he still owes you an engine built to the condition reflected on that invoice, he's not done yet.

 

Now that's the tactic I would take. Just my two cents. Get that f'cker, he owes you a motor.

I wasn't lying when I called him a IFR tweaker...that's how he tunes. I watched him do it to my truck before I got my software. He told me "I can't help it if you don't know how to tune your truck". I was rather calm, and never raised my voice the whole time. I need to make another trip down there, after I see whether the credit card company will do anything for me...already filed a dispute. I did take a witness last time, and I'll take him the next time also.

Damn Mr P you give some good advice, I hope I can pull all of this together. I wish some of you guys on here lived closer...it's always nice to have really knowledgable people go back you up when you have troubles like this.

Thats strange bearing wear, top side only.  :confused:  Looks like you might have had a little detonation when you were playing with the tune. Look at the rings and see if they are pitted from detonation.
No, I disagree - detonation manifests itself as bearing wear at the parting lines. Imagine placing a half-bearing on an anvil and striking the face of it with a ball peen hammer, the shell will 'curl' inward, and the ends of the bearing will scrape against the crank, and that is not what happened to this motor. This engine was reassembled dirty, I'd say from the cylinder wall scratches it was contaminated with metal dust; the scratches are *below* the rings, so the break-in oil was carrying whatever ate the motor. So my question is, you did change the oil after the first 30-minutes of cam break-in, right? If so, then all this damage happened in the first 30-minues, unless the original bearings were re-used. What do the mains look like? And were the valve stem seals completely shot or what, those cast pistons are coated with a bunch of gunk. :sick:

I was on my 3rd oil change in 1500 miles. 1st after 30 minutes, 2nd after 500 miles. The last oil had 1000 miles and was black...on the stocker at 3000 miles the oil was still clear. I have to make some calls today, and get it to a machine shop that is "unbiased" and pay them for a couple of hours labor to mic the bores and pistons. The guy I had measure my bores and pistons is a QC specialist at a Tool and Die company...he has 30 years experience. He brought gaige blocks over and checked the bore gauge and outside mic before we measured everything. I would agree that beyond improper skirt clearances, the engine was assembled with a lot of dirt in it...that and used parts(look at the crank gear).
