    Default Ten Famously Bad Automotive Engines -Jalopnik

    http://jalopnik.com/5614834/ten-famo...otive-engines/

    (Posted here in General due to A-body content.)

    #5 pictures a Century (strangely, with a Euro plate) naming the 4.3L V8 diesel. Also the comments section is filled with rants about the Iron Duke.

    They're wrong about the number of cylinders in the A-body diesel. It's six of course, not eight. And their reference image of the Century shows a "3.0 Liter" badge on the fender, which means it isn't even a diesel anyway. Someone in the comments noted that their Suzuki three cylinder pic is wrong too. These guys didn't do their homework on some of this shit.

    The only one I agree with is the Chrysler 2.7, but not for the reasons they listed. Also, I wonder if they meant "5.7 diesel V8" rather than 4.3?

    All in all, that's a pretty sorry list. There are far better candidates than what they picked out.

    They're saying late 70s V8 Diesel, so they must really mean the 5.7, which I understand. I have to agree w/the one comment that the Caddy 4100 is worse than the 8-6-4, especially since I'm pretty sure all of those were rewired as a regular 6.0 V8. -Adam

    I don't know about bad design of motors, but I will agree that half the problem is the lack of upkeep the owners didn't do to them. You could have the best engineered motor of all time under your hood, but if you do not do simple preventative maintenance on it, it is not going to last. I have not owned any of the engines on that list, so I can't comment on how difficult they were to work on, however, it didn't stop millions of people from buying them.

    edit. Hmm I take that back, I owned a 4100 Cadillac but I don't think it was the 8-6-4 configuration. I had a chance to chat with a retired GM engineer when I owned it, and he told me that GM never should have made that engine, or put it in the too heavy Cadillac. It was seriously underpowered. (Mine was an '84 four door Fleetwood)

    Well, the later versions of the 4100, the 4.5 and 4.9, were the same physically but more displacement, and the 4.9 made power consistent with its contemporaries of similar size.
    -Cadillac 4.9 (300 ci): 200 hp, 270 ft-lbs
    -Ford 5.0 (302 ci): 190-225 hp, 275 ft-lbs
    -Chrysler 5.2 Magnum (318 ci): 230 hp, 300 ft-lbs (truck only, unfortunately)

    I figured you guys might have a thing or two to say. I don't agree with the list either, like where are the Mitsubishi engines that burn oil like its gas, or the 3.8L Ford engine that nearly everyone I know had some type of problems with? Instead the list seems to be mostly composed of engines I've never even seen, and in a couple cases never even heard of. Of course I'm only in my 30s, but still.

    According to Wikipedia, there was a 4.3L V8 diesel, available only in the 1979 Cutlass, RPO LF7. Roughly the same output as the 4.3 V6 Diesel though.

    I had 3 Mitsubishi 2.6 liter engines, and even one 3.8 liter Ford V6. Never had a problem with the Ford motor (did you know it was based on the Buick 231?) but 2 of the 3 Mitsu's either burned copious amounts of oil, or leaked it. I had an 87 Starion with the turbocharged/intercooled 2.6, and that leaked rivers of oil until I could afford to have the turbo replaced. And one of the Dodge D-50's I had, burned it like there was no tomorrow. However, to be fair, it did have over 200k on the odometer when I got it. The Ford motor gave me no problems until I put the wrong size battery in it, and the alternator literally chewed a hole in the side of it, spraying battery acid all over the engine which ate away the wiring, and the Mustang just stopped dead. (Go figure )
