So today I pick up my car after the bottom end spun a bearing and I had it rebuilt. DogBox did the rebuilt. Another shop assembled to bottom end back to the head. I have new bearings, crank , pistons, ring , gaskets. So I had to drive the car to the body shop. I babbied the car the whole way , going through the gears , no boost , and not going higher than 3k rpms. The car smells like its burning oil , when i was sitting at a light i saw smoke coming from the hood and the temp gauge went up , but then went down. So im totally lost , broke and confused as to why my engine is smoking.I'm going to be bringing the car back on saturday to the mechanics after i pick it up from the body shop. Any ideas guys, on why this is happening. (do rebuilt blocks smoke?) i'd greatly appreciate it.
