My engine was running fine before I brought it in for the OFHG and for the few minutes I was driving before it seized. I took good care of it. Was under moderate normal acceleration and engine shut off. I didn't feel the car shutter or hear anything prior to it happening.

What color was the metal in your oil? Was it silver-y or more copper/bronze like?

My mechanic tried to manually turn it and it wouldn't budge. But yeah I'm looking for people in the NH area that have a lot of experience with BMWs. Unfortunately they're few and far between around here.

Man, post up on the facebook groups, see if there is a reputable BMW mechanic in your area with engine building experience. You can als contact Ghassan automotive, the only do BMW engines and maybe they can work something out under your warranty. You would have to pull the engine though which depending on your skill level might be a huge issue.

I had it changed 10 min before using the car but trust me what if felt like did not feel like it was related to the down shift I was cruising at about 25mph when it happened

Question for those more knowledgeable about the direction of oil flow: from the area of the OFHG repair, does the oil flow to the filter or the engine first?
If it flows to the engine first, that would increase the plausibility of the foreign material clogging passages theory. That theory also seems to line up with the seemingly instant failures without warning, no overheating, no prior knocking, etc. Granted, I have not performed the OFHG job yet on my car, but does the old gasket usually come off cleanly or require scraping off the gasket in chunks?

My thought of when this might be happening is if you have alot of dirt and debris on top of the housing when yo seperate it from the block it might fall in at that moment. Clean the surrounding area before you seperate the housing from the block. I have done this procedure two times. The oil passages are like 5mm in diameter if that. It doesn't take much i think.

It's rubber, so it should come out in one piece, however, if it's really old it could have been cracked/rotted and crumbled. Also, no way of telling what happened while things were opened up. Debris form outside the engine could have fallen in, like leaves/dirt/gravel...if the shop doing the work didn't blow the area out with compressed air, something could've fallen in.

Oh wow didn't know it was filtered/clean oil passage there.
Next time I'll do it I'll cover everything with shop towels after removing the housing from the car. If my engine didn't blow/seize after 1200 miles I'm good right haha? This thread is giving me paranoia, even tho I have a N54. |
