My 180k e39 decided this weekend was a nice time to destroy its rod bearings. Confirmed by the metal flakes in the oil and removed the bottom of the motor. Crank was not damaged. Can anyone give advice on if I should try to have the motor rebuilt or just go with a new one? My mechanic is quoting around $10k all-in for a new motor, including replacing the bearings on it. To replace the current bearings and VANOS, I'm looking at more like $5k, but he's warning me about potential issues down the line. Just a little unsure of going straight to a new motor.

It's extremely time consuming and costly to completely go through an S62.
It's best to sell me the core, and get another. (Washington state)
Now, if you opt to go through it, is your mechanic well versed in bmw motors?

10k sounds good I always hear around 20k

Yeah, I'm working with a BMW specialist who's both rebuilt and replaced a few S62s. I had actually already been planning on doing a complete rebuild of my motor before this happened. Just wondering if I should go ahead and rebuild it or put something new in.

I'm suprised at the 5g's number.
Guides, bearings, rings, gaskets, bolts, head refresh, vanos parts, are almost that, plus labor for a bare block build.
I do it because I like it. Not cost effective.
Benefits, no tick and no leaks.
Always looking for cores, especially blown up ones to scavenge.

Well, we're looking at $10k for a transplant motor or $5k to replace only the bearings and vanos. However, I would be into considering a ground-up rebuild of the current motor if it's in the same neighborhood of the transplant. That would give me some opportunity to do some improvements I had previously been considering, including possibly putting in some Schrick cams.
