Hey guys, unfortunately I believe my engine is Toast.
Driving on the freeway, sport settings, downshifted into second gear to roughly 6500 RPM, car is DCT. Car limped and engine shut off within 2 seconds. I was on a ramp and somehow managed to pull it aside on an high incline. Car had no signs of ticking or knocking, engine oil was changed 1 month ago, and I filled up the oil recently to max. I check the engine oil every week or so and it was at max. Had the car towed(disaster) as we couldn't get into it Neutral so we had to literally drag it on a flatbed(twice). After hours of roadside and towing, got it to my BMW mechanic, and he said the engine is most likely seized, with oil probably running extremely low. We checked for leaks, and I have a garage where there is 0 oil leak in my driveway. There were NO knocks, as I know these rod bearing issues and always kept an ear out for it. Went to 3 reputable BMW shops, and they told me it is 99% seized. It cranks with one tick and then just dies. No engine noise, battery charged. Can't be the starter because it happened at highway speed I'm assuming. Everyone is telling me the scenario that I need a new engine, complete swap, which I can't afford and don't want to do(due to resale difficulty). They all suggest not to rebuild, since it will cost a little less but more complicated and riskier.
Anyone have a similar experience? Car is completely stock, 50k Miles. I maintained the car well, did all fluid changes, pan changes, plug, ignitions, filters, all of the regular Maintenance.
I am really worried on dropping $15K+ on a USED Motor swap, as the car cost me roughly $<50K. Car ran totally fine, of course it was driven the way an M6 is meant to be, but not often.
Any input/advice and opinions would be appreciated, I'm really hoping for something less severe. Thanks for your time!
Got a potential deal for a complete motor swap for roughly $8500 with labor, motor has approx 30k miles. Is it worth just to rebuild it? Not looking to do anything past a tune and catless dp. Anyone think I just rebuild for the long run? Still trying to figure out how this happened, but requires a full tear apart which will run me 1-2k for labor alone. No knocking noise whatsoever for rod bearings . Anyone do a rebuild lately? Cost?
