Yes, the 5.7 was the gasser converted to diesel, although the 5.7 diesel isn't exactly like it's near clone gasser. As far as I know none of the parts from the diesel are the same as the gasser, they won't interchange. This engine was used from 78 on up to 85 (82+ were only in cars).

The 6.2 was designed and built by Detroit Diesel from the ground up and is the foundation for the 6.5.:exactly:

Hi,

The 5.7L diesel was a 350 Olds converted to Diesel. Joe Mondello ( Dr. Olds ) actually offered a kit to convert one back to gas.

Take care,

Will

I read a article about some guy took a diesel and converted it to gas. It was a GM motor I think an olds and he said being a diesel it was built strong so now he has a really tough gasser but i think he just put it back to gas. I dont think you could find parts that easy to convert a diesel to gas. So it must have been one of those, I herd they are Junk.

The 5.7 diesel was an Oldsmobile design. It was not a gas conversion! It was a diesel design. The block, heads, cam, I.P drive, etc., were all designed for the diesel application.

The reason people feel it was a conversion was because the valve covers, oil pan, timing cover and externals make it look (sort-of) like an Olds 350 gas engine. None of the parts will interchange. Yes, you can put gas engine pieces in and on the block and make it run on gasoline. It is a little tougher than a std 350 gas block. Deeper main bearing bolt boss threads, larger oil pan, bigger head bolt threads, etc.

When properly built, they were quite serviceable and many reached high mileage. I have two still running at over 200,000. They are not without head gasket problems, but other than that, the '81 and later DX blocks are buildable and will survive nicely if used as intended. That being, a light-duty fuel economy engine. Definetly better fuel mileage than their gas engine counter-parts of the early '80s.

It's kinda fun to fill it with diesel and watch the look on the service station guy's face!
