Smoking engine
A while back I did an oil change on my 1968 f100 with a 360. I got some oil on the headers and it started to burn off causing smoke, after a little engine degreaser and letting it burn it went away. But recently I patched all the holes in my exhaust system and let everything harden up and I put on new mufflers. (I haven't started the truck since June 7) and when I started up the truck, there was smoke. I let it sit for a minute just to burn anything off and its still smoking. I went into the cab to shut it off and I noticed that my oil gauge was all the way to H. Any ideas of what's wrong?
By the way even with the mufflers the engine still sounds loud by the headers.

What did you use to patch the exhaust? JB Weld? Where were/are the holes in the exhaust?

I was going to use jb but the guy at the store recommended muffler cement because it was a lot more for the same price.

There wasn't a lot of smoke, just like a small brush fire. It was white and I don't remember what it smelled like but it was coming from the headers. Nothing is on fire.

If the headers are smoking, you just gotta let them burn off whatever is on them.
Headers temps can reach over 500 degrees. So they're gonna burn stuff.

Sounds like two problems here. 1. something (sealant, oil,or epoxy) on the headers. and 2. Something has happened to the oil pressure sending system. IF the smoke is definity coming from "something" that is on the headers, is the "something" dissipating? Or is more of the "something" coming from somewhere? As far a problem #2- Do what HIO said! Look around with the engine off first! Check all fluid levels, belts and wires. Keep wires away from the headers-including the starter power wire! Everything look OK? Then start it and have a helper look with you. Use flashlights if need be. Check underneath too.

1ST I'd spray the headers down with Brake-Kleen to clean them off. This will clean, dissipate, and leave no residue. Now the gauge being pegged has to be investigated. Either the wire is grounded as mentioned above or the pressure regulator in the oil pump has stuck full open.
