Name ONE diesel engine that shares half as many parts as the 5.7 Olds diesel does with a gasoline engine and I will believe you!!

The GMC V6 back in the 60's had both a gas and diesel which used many of the same castings. Unlike the Oldsmobile I believe the block and crank were identical.

That very well could be true. I'm unfamiliar with GM diesels of the 60's.

Like I said above. It's semantics. It's the same block with just more metal here and there. Is it the exact same casting? No, because it's a diesel. I'm not saying that Olds pulled the same block off of the line and made it a diesel. But it is the very same architecture. Like I said, it still has a distributor hole in it!!!

It's much like the Chevy V6's of the 80's. The V6's are just a small block Chevy.................with two cylinders lopped off of the back. That way Chevy did not have to design a completely new engine and they had a proven design that worked out of the box.

Olds tried this with their gas engine and tried to make a diesel out of it. They tried to make it work by making the "gas engine" a diesel by making it a high nickel block and putting more metal in the bottom end and putting in a big block forged steel crank. As you know, it just didn't work because it was a "gas design engine" from the start and no matter how many band aids they put on it or how much extra metal they scabbed on it, it would not work..............or at least work well.

"My" 5.7 has given me less problems than my LBZ truck. My 5.7 has never given me one problem but my LBZ has had one glow plug go out. That being the case, in true RV.net style I will say "it's a great engine" because I own one and it's never given me a problem. :B
