Smokeless Engine Oil? REALLY?

[ArkRescue]

Just spoke to shop owner who said he's trying to figure out what could cause lots of smoke w/o high oil usage - I wasn't putting in a lot of oil during the months it started smoking like that. I said could a bad EGR cause that much smoke? He said he needed to think about it, but that a compression test would yield us some helpful information. Said he'd call me back after he gave it some thought.

Oh he also mentioned he was in the process of cannibalizing a 1996 Suburban and maybe that engine could work in my SUV? Now knowing there is a distinct difference between the 1994 and the 1996, would it work if it came to that?

bcp hit the nail on the head and GWGuy is alluding to it as well, you might not need a new engine. You need good troubleshooting to take place first. It starts with the CEL code that is thrown by the truck, from there the troubeshooting begins. Thinking about it and putting testers on parts while watching it operate are two totally different things.

As for the 1996 Burb parts, ask for the bumper (I think they are the same as yours). To make a simple answer to your question without seeing the Burb no. My comprehension is that OBD II took full effect on trucks in 1996, which brought the last incarnation of the traditional Chevrolet small block in the "Vortec" design. The engines are similar but the computer, fuel delivery system, and cylinder heads are different than yours. If he is willing to swap engines make sure that he is willing to swap the computer and the associated harness to properly control the engine. If not, your CEL will be on and you will get booted out of the VEIP station
