I am sh*tt*ng bricks right now. I am nearly done assembling my freshly rebuild 283. I had a shop towel chunk plugging the oil pressure sensor port, and when blowing the engine down with air, poof, it’s gone. Into the hole and out of sight completely. I am so scared that this block is done and I’ve completely clogged and oil channel. If anyone can ease my mind or help me get it out that would be great.

 

I blew through the oil filter housing hole and it reappeared at the bottom of the pressure port… still not sure how to remove.

 

With some help from a pick, a shop vacuum, and an oil galley map, I got it out. Crisp averted
