Blown Head Gasket.....

Pics. Let me known if anybody sees anything I don't. It's possible the rings are bad, cylinder wall is damaged, valve seats are shot. It could also just be that I wasn't exactly at TDC; I'm used to t hings with more than one piston. There is a lot of oil around the mating surfaces which does lend itself to a blown head gasket but now that I've busted two of the bolts off in the block who knows if it's worth pursuing.

The scratch marks on the top of the piston are superficial, they are from me trying to find TDC with a screwdriver stuck through the spark plug hole.

any time there is a cleaning action at the edge of the piston area, thats a clear and positive indication there was blow -by around the rings. the valves dont appear bad from that view. the closed valve and intake or exhaust chamber filled with mineral spirits will show leak around the seat and valve oh to well. minor weepage is not so bad as a stream of fluid. what was the compression?

that engine should have run as it appears in the pics....

Mid season last year it did run like the pics look. It was spewing oil like there was no tomorrow and smoked like crazy.

So, do you think it's worth pursing this as a repair or just junk it? If I pursue a repair how in the hell do I extract those two broken bolts? I'm going to guess it's junk as I've been told.

I didn't do a compression check as I seem to have misplaced my compression tester. The I also didn't pay attention to the numbers on the leak down as I was just checking to see where the air was coming from.

Well...soak the broken bolts with deep creep or a good magic penetrant, and use a left hand drill if you have. Or a drill press and regular drill. 250 rpm and with patience. You may get it. If not then helicoil the holes. The heli coil kit is 40 bucks or so.......mic the bore. And re ring it after honing.... Bore stone hone. 60 bucks. And a ball hone....80 bucks.....pull the valves and inspect....have seats cut and valves faced....lap the valves.....




Ok. So scrap it and buy another motor.......errrrrr. A good used mower!!,! A nice wheel horse! Or Airens. Or Simplicity

Or ( for w&c). Even a green and yellow. John dearrrrrrr ear..... 8-)

There are so many used mowers on CL in which you can get a good deal....
Those broken head bolts....I'd go find same model if there are any other salvageable parts left.

I'm still using my $123 Snapper I picked up 7-8 yrs ago on CL. It's tough!

A good machine shop could get those bolts out easily . Might be worth it. How is the rest of the mower?

Are you sure it's not just a little too much oil in the sump? Maybe the float stuck and it's diluted oil/gas? Nothing I see smacks of terribly bad rings or anything that would let oil flow like you're seeing.

Rest of the mower is in good shape. It needs belts buy that's regular PM.

Cabinover, it's possible there is too much oil.

I think I'll call around to a few places and see how much it'd cost.

Swung by a repair shop on my way to the next job. They said what it'd cost in parts to repair it and labor it's not worth it. Even if I did the work myself it's not worth it. If I bought a new engine, it's not worth it. The guy I talked to said that it'd be cheaper to get a used one off of Ebay because it'd cost about the same. OR I could take the money that I'd spend on the new engine and go buy a new tractor.

Bottom line is, I'm going to salvage the Carb off of it; it's the same one that is used on my generator I'll rebuild that but the rest of it is going to the junk yard this weekend.

I'd just drill those broken bolts, Helicoil them, buy a new set of rings, ball-hone the cylinder, and get some lapping compound and go at that intake valve for a bit. I'd bet you'd get another 5 years out of it at least.

Was working on it, found the problem, got the part (key switch), then borrowed the rear wheels and tires off of it for my other one, then it got buried under a pile of other stuff in the barn. :D :D

Yeah, knowing my luck though it won't solve the issue or something else'll break. Nah...I'm going to cut my loses on this one and just get rid of it.
