What blew up this motor?

**Slappyn** · 01-02-2013

112,000 miles. I think it was lack of care and extra stress from the sc. BTW the boost pushed passed the piston and pushed all the oil out of the motor.

thats clyinder 3 right

**vandezand** · 01-02-2013

too much kr causing chipped piston?

**ItHurtz** · 01-02-2013

kr.

It always tickles me that those chunks mangle themselves out of the engine

**Slappyn** · 01-02-2013

That is #2, bone stock always running 91 octane (from what I am told) But the plug was destroyed as well.

motor number 2 or clyinder 2

Not uncommon for the middle piston on either bank to chip from detonation, since it will frequently be the hottest/leanest running cylinder out of the bunch.

#2 cylinder

No it is not. It is either cylinder 3 or 4.

Seems like you need to learn these engines more before tearing them apart..

Is this the front of the engine or rear?

**BillBoost37** · 01-02-2013

Firewall
2 4 6
Center of engine
1 3 5
Radiator

That's how GM numbered them.

PS, cause of the blow up.

Look down at your right foot.

**blueguy** · 01-02-2013

That is 3 or 4, because apparently now the firing order is...

456
123

Thats a mean thing to say since it is more of a cutlow than relevant (I had no trouble "tearing the engine apart").

**Slappyn** · 01-02-2013

Its the front #3. My bad.

lol. I picked it up off of a guy who had just bought it a month earler. He parked it after it blew up and it sat for 7 months. So his right foot is the culprit. haha

**BillBoost37** · 01-02-2013

Yeah..it's common enough to happen. Likely he tossed in lower octane than he should have and beat it a bit too much.

**Slappyn** · 01-02-2013

Yea come to think of it he may have told me that he was running it off of lower octane. Guy knows nothing about cars. He paid 3.3k for it and it broke down a month later.
