We don't need no stinkin' rebuild!

So I was helping a buddy work on his car today... nothing serious, just a rad flush and oil change. We jacked up the car and popped the lower rad hose off, draining (most of) the coolant into the sort of plastic oil tray you use when doing backyard oil changes.

It quickly fills about half full of green coolant. My buddy notices black drops in it, coalescing into a fine swirl of engine oil.

'Oh crap' says he. 'I think my engine is fucked'.

So I tell him not to panic, it may just have been old oil in the junkyard rad he recently installed. He's understandably concerned, and mention is made of buying my 13B out of my old car.

We run the detergents through the engine and dump the old fluid into a bucket so we'll spot any new oil in the water as we rinse the rad & engine out. He's still concerned, cursing about oil leaking through O rings, etc...

I spend about 5 minutes cleaning the oil droplets out of the oil tray so as not to contaminate the 'evidence'. Just as I finish, he turns to me...

"Man, we're dumb", he says. "I didn't clean the tray out last time. That was oil from my last oil change."

whata dumbass.... I've done similar, though...draining the engine oil into my similar plastic oil-catcher and noticing tons and tons of metal filings floating around...I go into a panic thinking about the costs and bullshit involved in taking care of it and then I remember that my catcher was lying right behind my metal cut-off saw that I'd been using extensively the last couple days. There were enough filings in the oil to make a whole piston from that engine...

I've had backyard mechanics expirences just like that.

I was replacing the head gaskets on a buddy's car with him along with an oil change. After draining the oil, we get the heads on the engine, he fires it up and revs it to redline imediately followed by "tick tick tick tick tick" i say "hey, oil helps". Needless to say, that was the end of his bearings.

ouch...damn...last time I changed a head gasket (except on the supra) we did it slightly inebriated and left on of those lil craftsman stubby short screwdrivers on top of a piston. Beat the hell out of that poor lil screw driver...

A guy I know dropped a washer or two down the carb of a running RX-2 12A. The front rotor looked beautiful after that. Luckily, the front and intermediate plates were still usable.

Hey, it was funny though! At least I figured it out before I cut you a cheque for the 13B prematurely.

Meh. We've all made stupid mistakes in our time, this one is just a little stupider than most.

Not exactly the same type of thing, but do you all remember the picture of the inside of the Miata engine where the rebuilder kid "helped out his daddy" by dumping BBs in the cylinder head?
Anybody know where that is? It was up in this section as well as the lounge.
