Not 100% sure but yeah I think this motor has been sitting at a dealership for a while. It will eventually be rebuilt and put in a race car(probably).

I've driven my Comanche around with 2 quarts in it also... run it out of oil on the highway dozens of times, it leaked like a sieve and I didn't have the time to fix it. Oil pressure remained fine with no bad noises.
Yeah, re: the post kastein quoted, the Ford 302 acts more like a big six than a V8. A Ford 302 V8, Ford 4.9/300 I6, or, in kastein's case and anecdotes from my Jeep-owning friends, either Jeep I6 will keep running in any two of the following conditions: upside-down, underwater, no coolant, no oil. There were stories during cash for clunkers of Ford I6s running for an hour or more with liquid glass (i.e. aqueous solution of sand) in place of oil. I passed my I6 F150 down to my brother, who got in a fender-bender that tore a 2" gash in the radiator, and it was still purring like the proverbial kitten when he replaced it a year later -- he only drove short trips around town to school and such, and topped it up to the hole in the radiator before leaving every morning.

I've personally intentionally killed* one 302 with a lot of effort (similar symptoms to the one below, and once we got bored of it running fine with no oil or water we started pouring degreaser into the oil-fill hole).

*we gave up when it seized and the "check engine" light came on (protip: most CELs tell you there is a major problem but you can limp home, a CEL in a V8 Ford** means you should immediately hit the brakes and find a place to pull over, because you're about to lose your power assist); judging from the later experiences below, it would've been fine if we'd topped off the fluids but it was a beat-up company truck and a boss who wouldn't replace it unless it was hosed, and apparently we killed it hard enough for him.

I've driven another 302 ten minutes across town with a massive coolant leak (freeze plug or cracked block, it overheated to seizing a few times out in the boonies and I filled it up and drove home as soon as it cooled down enough to start), a blown head gasket, and the burnt-to-poo poo-oil/coolant emulsion barely showing on the dipstick (with two half-flat tires to boot) when I moved house, couldn't afford a tow, and had pretty much written off the engine already because of the milkshake coolant pouring out as fast as I could put it in. No problems in the last drive aside from a hellacious rod knock. Hell, it seemed to run better than the last time I'd driven it (and dumped a couple bottles of liquid glass in the radiator).

One of these days I'm either going to rebuild that fucker or take it apart for paperweights, and then I'll post pics.


**I've overheated a 4.6L, and the ECU drops every other cylinder's spark as an emergency cooling measure at the point normal cars would throw a CEL. The warning light comes on about half a minute later, 1.4 seconds before the radiator cap succumbs to the pressure and gives your engine a hot bath. Ironically, the best solution to rough running and/or high temp in a 4.6L is to floor the bitch, because 40mph is the speed at which the forced air from moving will keep the engine nice and cool with no fan. The radiator fan on my '03 Interceptor has been dead for over a year now, and I haven't had a problem after that first time, when I learned to park and go in for my "fast" food with a long line, and plan my commute to avoid traffic jams when it's over 100F outside.

It actually doesn't take all that long for engines to rust like that. When I took an engine rebuilding class, this point was stressed after a student didn't oil their block after putting in the washer. The next day every machined surface on the block had rusted over.

I've been in, and driven, cars that were temporarily held together with things like that. When you're poor, and in the land of rednecks, it happens quite frequently. As long as you do it right, I don't see a HUGE issue. (right = the least-un-safest way out of the collection of unsafe ways you're going to have to go about the problem).

Key word is temporarily, though.

I've posted about this before but It's worth noting again that the Ford 300 I6 was used in this loving thing.



I mean look at it. It has a god drat solid steel Jason mask for a grille. They used these at FedEx when I worked there to push, pull, tow, drag, and do violence upon anything that needed it. I saw them run into poo poo so hard they stalled the engine, and they started her back up and kept going. I saw another guy ram into a concrete pillar, and stand on the accelerator while the knobby tires dug a hole in the asphalt.

I don't think it takes much rpm to cause damage when you are talking hydrolock, but I'm not really an expert on engine carnage. I'm just a software developer that works in a car shop, heh. We aren't doing the engine rebuild here either. The engine is being loaned to us so we can do a little research regarding valve clearances with the VVEL valvetrain. I would assume they would bore and sleeve it though as the cylinder walls are a bit nicked up.

Even at idle, there is an enormous amount of force being transferred through an engine. Doesn't take a lot for hydrolocking to wreck an engine.

Yeah I develop reflash software for factory ECUs. I'd consider it more reverse engineering than embedded development. I also develop the desktop applications that allow end users to tweak their tune.

Once the pad shoe breaks apart and falls out the piston will hit the rotor and not come back, making the car immobile. Well, that's what happened to me at least :o:

I thought you were joking earlier. Here is what a brake rotor is supposed to look like:



See those radial vanes that are sandwiched between the two solid chunks of steel? Those are what you see in Gnarly's picture, because the person kept driving until the utterly destroyed brake pad wore completely through one side of the rotor.
