Hello, I'd like to ask some input from you,
I've recently had my N55 engine replaced after only 85K miles. The engine developed a rod-knock and was promptly towed to the dealership and back after the diagnosis. I purchased a re-manufactured engine from a company (I'm going to leave out their name for the time being but may update later * update 5/3/2019 - Ghassan Automtive in Stillwater, Oklahoma) that charged me $4k for a rebuilt engine, and $1500 for a core charge (plus shipping both ways). I received the engine and had a local dealer install it. The core was picked up and they have had it back for over a month now. I am having issues with them regarding the core refund. Initially, was told that the core "really wasn't savable" and I have asked for further explanation, but haven't received any responses, calls, or texts back regarding the issue other than "they will contact me later". They keep delaying.
I am curious, can an engine that was running absolutely fine with 85K miles (no stumbles, no codes, etc) which developed a rod knock and was towed to the dealership have so much damage that cannot be "savable" or "rebuildable" by core-return standards? I can totally understand if a rod punched through an engine block, that makes sense, but this engine was running fine at removal and I was told it was just the #6 cylinder bearing that developed the knock. Engine rebuilding would typically encompass new bearings, rods, etc at the least if needed so I am left curious why my $1500 core charge is not being returned, or is this just another way to get a little more $ out of people?
The rebuilt engine has been fine so far (1.5 months) and I don't have any other issues with this company up until this but figured I would ask those of you with engine rebuilding (or core) experiences.
Thanks in advance.
*edit - I have added the company name on 5/3/19 because to date, I have not received my core refund and now he has gone dark. My original purchase date was 2/5/19.

BMW refunds core charges even when a rod does punch a hole in it. But seems like this company wants a rebuildable engine.
The main issue is that when an engine spins a rod bearing, the crank is usually destroyed. Hard to say whether or not the crank can be saved.

Seems like the company is not being straight about the core money, even if the crank was bad you can weld it and Remachine it
Agreed. I've never experienced a core having that bad of an issue, especially given the circumstances surrounding this particular situation. If the crank is that bad (which he is saying it is), I am hopeful at least we can come to some decent terms.
Indeed. He did mention it contained micro-cracks, which the machined, then welded, and machined again but ultimately, it failed and was not salvageable. With the exception of the crank and #6 rod, everything else (block, head, etc) was fine. I just think it's unreasonable to not return any bit of the core.
It's been over a month and a half now. He asked that I reach out to him at the end of this month to discuss further (which is frustrating by itself). I was happy with his initial communication prior to the purchase and have been happy the engine so far but this kinda of lack of follow-up at the end leaves a bad taste in my mouth. I'll keep my fingers crossed. Thanks for the input you two.
It depends on the specific core-return policy of the place that sold you the motor. But in my book, if you send back your old engine and all of the parts are present and accounted for, you should be getting a full refund of the core deposit. His business is rebuilding the engines and selling them for a profit. The core return process is supposed to guarantee a steady stream of product, not finance the operation.
If it is damaged, it is worth less or maybe even worthless. A rod knock engine may well be one if the two.
If you have a relationship with rebuilt engine suppliers because you give them regular business they probably won’t hassle you as much as a one time buyer if there is an issue with the core.
Well, it is has been almost three months to date that I have made a transaction with this shop in Oklahoma, and the owner has put off returning my core (or any part of it) for months now. I'm officially out of patience and will proceed to do what I can legally to have this rectified.
Ghassan Automotive (www.ghassanautomotive.com) in Stillwater, Oklahoma is the shop. My reman'd engine has been great (so far, knock on wood), the whole core thing has left a bad taste in my mouth.
*edit - 1 hour later after filing a complaint, I finally received a "partial" core refund.
