Author Topic: Nut fell into motor. (PICS!!!) (Read 5606 times)

I finally had time to check and decided to remove the head on my motor that previously seized up on me.

I only found one nut laying on my piston head.. what gives? :eek:
So can anyone help me find out why Im missing three other nuts from my motor?

LOL...

How bad does this look?
I cranked the motor by hand after removing the nut, and it goes around smoothly.

Wonder how this happened?
I had some work done, the crackpot who put the head back on dropped the nut into the chamber somehow, or maybe through the spark-plug hole. Thats my only guess???
Looks like one of the nuts used to hold down the camshaft.

Since then I picked up another m42 and its in my car now running fine... but I'd like to put this one back in my car because it was not leaking, and was in overall good shape, timing components, water pump t-stat....

What shall I do?

actually, altho it looks ugly, none of that damage looks like an engine killer. I would tend to think that, after being reassembled, it would be a good back-up motor. With a new head gasket, and assuming it passes a compression test, it will be fine. Altho, you may need to stay far away from the guy who dropped em in there..

I agree, run it regardless. I might give that dinged valve an overnight leakage test first...but your nut-stamper is quite the testament to BMW's metallurgy, isn't it?

Recon you were very lucky it didn't catch the corner of the valves and mash up them up.

con rods possibly are bent, so better check them...

He did say the motor seized up, so it would (will?) be interesting to find out the extent of damage.

I'm guessing how many revs it was turning when it seized,

Seriously... I like me my M42 more year after year.

Yes, my thoughts exactly.

Sure hope not, but I have high hopes for the better.

LOL, Well I should have mentioned the car was driven back n forth for about 3 days, and felt fine before the incident. But, THE GOOD NEWS about it seizing up is that it happened upon starting the car/the car not starting one day. On this day I drove a couple miles to my parents, parked the car for a few minutes than when I was about to take off, I started the car but it barely turned over and then would not start. after pushing it into the driveway I later noticed the motor was seized. Fast forward, motor was replaced and sat in garage til this month.

the fact that it was barely turning at all when it locked up bodes well, for the bottom end, I think. I'd give it a chance to live again.

Definitely!!!

It took me this long to take a look at it, imagine how long it'll take me to get it back in a car!

Come back for thread updates in say.... 1 year. :rolleyes:
