Re: OUCH - big engine problems, will not turnover even by hand :*( (Maurice)
Update if it helps anybody.
Just drained the oil and it smelled very gasoline'ish. Didn't notice any metal parts or shavings in the oil. The oil was black.
My plan of action is to start at the top and work my way down. I am going to pull the intake a heads, then if I have to pull the engine, I will do that next. Anybody got a better plan?

IMO, I would start with the oil pan and timing cover. Oil pan is usually quite easy to drop, just undo idler arm to lower steering linkage. It is best to get the best overall view of the engine without disturbing it before you dive into it.

Did you filter the oil with a coffee filter? Did you disect the engine oil filter?
If nothing else good comes out of this.... I got so frustrated last night unratcheting the headers, that I went out and bought a 5hp 23gallon air compressor and a set of air tools!!!

OK, my turn to guess. I'd say it tried to sieze either a piston or stack a rod bearing on your trip. You didn't mention any smoke, so I'd tenatively rule out piston. For it to turn over and then make the "mechanical" noises you mentioned, I'd say it tossed a rod or broke a piston at the pin. When you drain your oil, you'll get your first clues. Either aluminum shavings, scraps or chunks for a piston, or metal shavings and/or parts for a rod. Either way, your super lucky it didn't detonate on your little trip and take a valuable block with it. I'd bet on major bottom end damage.

If nothing else comes out good from this at least WE have a nice set of air tools to work on OUR vettes with.....Good luck hope you find something simple and not a major overhaul.....I still think you should pull both heads first before ripping into the bowels of that thing.... Let me know if you need anything or a helping hand......:seeya Cappy

Maurice,
Remember that if you cut your filter open, don't use a saw. Tear it open, and do it over a coffee filter which was a good suggestion.

I was having a good time last night putting everything together. At 9:40 last night, my wife comes out yelling "CAN YOU STOP DOING THAT!!" Doesn't she know that the little boy in all of us have wanted an air wrench that sounds just like the tire store when they are taking off your tires.

Maurice, sorry to hear about that. :( It was a fun car to drive. Hopefully you get that beast back on the road soon. But after doing all this work, you may not want to sell it! ;)

Maurice, I like your attitude--sounds like you're almost having fun tracking this down. I'm enjoying the heck out of this thread--it's like a good mystery novel. Who says the forum has gotten boring?

Re: OUCH - big engine problems, will not turnover even by hand :*( (terryrudy)
Sorry to hear that. :(
same thing happended to me. 4 months and 3k later. :cuss
I'm casting my vote for broken timing chain/gear. The inability to idle and poor mileage is a good indication of having 'jumped time'. The fact that it went away again before the engine failed entirely sounds consistent. If the top sprocket was the stock aluminum & nylon type, the normal condition in old age is that all the nylon tooth 'caps' break off and only the smaller aluminum 'skeleton' is left. It's small enough to allow the chain to jump to a retarded state on a hard acceleration and on occasion, to jump back again during hard deceleration. If left uncorrected, this state is usually followed by either the complete break-up of the top sprocket and subsequent 'wadding up' of the chain around the crank sprocket -OR- the chain jumping several teeth at once, resulting in valve-to-piston contact followed by total anihilation of several reciprocating engine parts.
Good luck...I don't envy you, no matter what the problem turns out to be.

If you small gas in the oil, thats bad!
I would just Pull the engine.
It's not the water pump
If it's anything else, even the timing chain you need to do a complete clean up and rebuild due to metal all throughout the engine :U
So Just pull the engine now, everything will be much easier...

Re: OUCH - big engine problems, will not turnover even by hand :*( (427V8)
I had my crankcase fill totally with gas when I had it parked on my parents driveway for a few weeks. The driveway is on a steep grade & I have an electric pump that will free flow. I went to crank it and I thought the battery was dead. I went to jump it & it cranked the same way before it fired. I shut it down when I noticed it only had 10 psi oil pressure. That's when I found the gas in the motor. Luckly, I didn't break anything.
Ever since then if my car is parked for a while I will remove all of the spark plugs and crank it over enough to get oil pressure and to "clear" the cylinders.
Let us know what you find.

Re: OUCH - big engine problems, will not turnover even by hand :*( (terryrudy)
No updates as of now. I had to work a bit late last night and was busy with less important things so I didn't get anywhere. I have come up with a more in depth plan though. The last thing I am going to check before pulling the engine is the distributor, then the engine will be coming out and I will dismantle and see what I find. Next, I am going to take it to a machine shop just to make sure that everything is as it should be and then put it back together with not such high compression so I can run on pump gas. I am also going to put a new clutch in as one of those "while I'm at it" things.

Checked the distributor... Looked good. Worked on getting the engine ready to pull unhooking everything. Should be a very busy weekend coming up.

Aren't you going to try and figure out what went bang first, I completely rebuilt a motor once because of a misaligned intake gasket, once it's out there's no turning back

Have you checked the clutch disk and pressure plate? I have heard of the clutch letting go and jamming up in the bellhousing and not letting the the engine turn over. Hope you find the problem. :confused:

Re: OUCH - big engine problems, will not turnover even by hand :*( (MotorHead)
I think at this point whatever I find is going to require that I pull the engine anyway. I am going to go with lower compression pistons also so I can run on pump gas. Maybe slap on a new set of aluminum heads and new cam, while I'm at it new clutch.... the engine has to come out.

I haven't checked the clutch yet, but it seems to be functioning correctly. I can put the car in gear and it doesn't move, push the clutch in, it does move.
