So I'm replacing an engine in

[M-technik-3]

a E36...yeah i know should have junked it but worth more as a flipper than parts were. Anyway has a bad engine and I was like wonder why. Pull engine....so on pull plug one out rotate to TDC and guess what?

Hole right through the damn thing. You can see the rod below. No FI or anything. Wonder how they did that as looks like it's dead smack in middle. Thinking Wrong plug/too long of an electrode an Over Reved the bitch as it has a S50b32 cluster to 8K. Oops.

Pictures after head is off.

Oh oops, I read that wrong. Sounds like an overrev victim!

Thats what I am thinking.

I once bought an s50 knowing full well it was blown. I figured it was just a head gasket but after I pulled it out, I noticed a rather large hole in the block right where cylinder 1 is (cylinder all the way in the back). Turns out, the engine was overrevved, and the driver kept driving this way for who knows how long. The piston disintigrated and was scattered throughout the oil pan. Notice the cylinder wall and the hole protruding the wall of the block.

This whole motor was trashed.

Bad mixture. Thats a shame..

Piston one is in the front. Just to let you know. Nasty hole in that engine.

It'll buff out and thanks for the clarification on the cylinder placement.
It's the little things that I sometimes forget or never seem to remember.

[M-technik-3]

no biggie

[jrdeamicis]

I am almost 100% positive the cylinder # is counted from the front of the engine.

[M-technik-3]

It is that why I mentioned it. He now knows.

[FredK]

wow preshkid... that is GNARLY.

[phreshkid]

wow preshkid... that is GNARLY.

Yeah I just threw everything away. I bought it for stupid cheap, mostly for the harness, ecu, and obd1 parts. I doubled my money very easily after selling little stuff off that motor but the block/head was indeed trashed.

Here is the head just for reference. Looks like a damn pasta salad

Thats what happens when you have a knocking rod and keep driving the car..

I Saw the exact same thing in a 323 I stripped but in cylinder #5, the rod was bent into a J

Car was bought with a known dead engine. Hence why the car was getting M52 vs just a plug and play m50.
