Hey all. I just finished building up a 1FZ-FE starting with a new short block, and a rebuilt head. I filled it with fluids last night and checked this morning. No signs of leaks or anything. This morning I pulled the coil wire, let it crank a few times to build oil pressure, and then plugged in the coil and fired it up.
It pretty much started right up, and sounds like a normal 1FZ, but almost immediately started smoking. It looked like it was coming from the exhaust side, but not really from any seams that I can tell. It looked like the headers themselves were smoking. They were off the truck for months, and I cleaned them with degreaser so maybe it's residue? There are new exhaust gaskets on the block and at the y-pipe as well. I mean, there's new gaskets everywhere, but again the smoke looks like it's coming from the exhaust side.
So I wanted to ask anybody who has experience with first-starts of a new or rebuilt engine: Can smoking like this be a normal thing (especially with reused headers/exhaust) when first running in an engine, or is this major cause for concern?
I didn't let it run for very long to see if it would sort itself out for fear of damage.
