This was the end of the road for my last motor

Yeah, yeah, yeah. . . . Of course you're right. Still got my mind on the 911 jugs. Or was that P. Anderson's jugs . . . I still get 'em confused!!. . . the left and the right I mean. . . . Oh. . forget it!!!

Close enough to the same damn thing though. . . DON'T HONE!!

Oh and BTW Granite. . . that righty tighty, lefty loosey stuff. . . . It don't work on Mopar lugs!!! I don't know about P. Anderson though

I'm just wondering what the hell Dean did!!! Good job bud!!!

I've hydrolocked one of these before. Cracked #3 from the top, clear to the bottom. Talk about being peeved. When I tore it down, other than the crack, the block was essentially new!!

It really does take alot (sans stupidity) to destroy these!!

Looks like there is some motor confusion in terms of treatments. DONT GET THE THING HONED? is that the final decision?

The reason i started this post is because I had my starter freeze up the other day (or solinoid). I went back to my office where it was parked and tried to bump start it. Unsuccessful. Then i tried the key again... it started right up. Kinda like that old trick with the hammer and a starter. None the less i was driving my borrowed 4 runner while my buddy was driving my car. On the freeway he must have over revved the crap out of it, cause when we got off in our home town i could hear it click click tick tick tickity. I then realized that we were in to some major knee deep shiza. Now i think this is the rod bearing, almost positive that that is the issue. oil pressure i s all over the place and the thing runs, just clangy. I wont start it again after that day cause i want to save my crank.

LET THE PROJECT BEGIN!


BTW: i am driving a Chevy Citation II 2.5L Fuel Injected !! Its a great piece of work. 4 door hatch sloppy in all aspects of the word... BUT it gets me around were the porsche is lacking in that department. It ran so good too!

Doing about 100mph into the bus stop at the glen. Accident in front of me. Battery from one of the cars squirts out and I run it over. (probably doing 80-90 as there was absolutely no time to react) Battery goes directly under the center of the car hits the end of the crank. The pulley gets bent and the bolt holding it in place is then loosened. The oil pump instantly freewheels and the #2 bearing lets go. Sent pieces of metal everywhere in the motor scored most of the cylinders. The really bad part is the motor had less than 10 hours of total run time. I salvage the head (ported and polished) but basicaly the entire rotating assembly was junk. My new pistons, crank and block..... .. All Junk. The only good part was my friend who raced these cars gave me his backup motor from his 944 and it is an even better/stronger motor. I did not even mention what the impact did to the transaxle. That was a very expensive day at the track.

A hole lot more photos of the carnage can be found here.

Is there a "how to rebuild your 944 engine" book or anything like that? The workshop manuals are swell, but something in more plain english would be fun.

Yes that would be good.

Does anyone have a list of parts and a total cost for the rebuild. I want to compare it to that $5-6000 rebuild quote by Akers Porsche, Seattle.

A 240 Flex hone would be what I would use on it. the cross hatch angle also depends on the ring type.
For most engines this would hold true. Not for the 944. It shocked me when I found out.

You don't hone a 944 bore and you can replace the rings without refinishing the bores.

Best for you to do some research before working on one of these engines.

Not from reputable builders of 944 engines.

I always just use some 80 grit sandpaper and a little WD 40. Works like a charm.

I vote for a hand drill and grinding wheel.

CCHYPER - I can't remember for sure but I think I spent about $500. This was the gaskets and seals, rings, bearings (crank and rod),.

Add another 500 for all rollers for the belts, new belts, etc.

The heads on mine were in good shape. I lapped them in (oh, and ported and polished for what that's worth in a road engine). But I'm figuring you can take them to a shop for about 500.

You also might need: Pilot shaft bearing, clutch, etc.

You'll only be able to get a better figure once you've torn it down and have been able to check the heads, crank, block, etc.

Thanks, i think that i found a rebuild kit for 650. My head was rebuilt about 20,000 ago... Its probably ok... you never know tho. Also i will be replacing all the belts, seals and gaskets while its out... Why not. So i assume an estimate of about 1100? is that about right for a do-it-yourself rebuilf of the bottom end + some?

But again, if you have it out and you can do it easily, spend the extra $ to replace the clutch.

Sounds pretty close.......maybe.

Hehe, in my experiences with this sort of thing, and just about ANY project I get into, I've found that if I plan out everythng the best I can, estimate all the "costs", the very best I can........and THEN.......if I add 30 to 40 percent to it........I'm much closer to the real, end of project costs. And still, I end up underestimating the costs of many a "project". Is this just me? I doubt it.

Have fun, and good luck!

I knew someone would get a kick out of that.

I actually bought a bare 944s block a couple years ago and was assurred it had been honed correctly by a pro porsche guy. When it showed up it had been sanded or something and was a total piece of crap. Problem was I had a grand into it and couldn't send it back.

I don't care what he said, I think he honed the cylinders himself on the last headgasket replacement, and re-ring job! LOL!
