I'm new to these forums but I think I came to the right place. About a two months ago I noticed my truck was running a little warm. I parked it and left it for a couple of hours. I went back out side and noticed a big pool of oil right underneath the block. I started it up and although running low on oil (gauge tells me running at 10 psi idle up to 30 psi revved or working although when it starts to get up to 30 it starts bogging down. It usuall runs @ between 30 and 40 psi) it sounds like nothing is even wrong it. compressions sound great everything. Well when I put more oil in it It leaks it out after a while and you can see the drips while the truck is running. I can't find the leak. I had a mechanic tell me to check the oil line from the pan to the gauge still having a hard time trying to find the leak. Any suggestions?

Oh. It's a old 1987 short box s10 with a 5.7 327 sbc. 350 turbo tran, .373 gears. Picture attached.

just remember oil moves backwards and down. so find the highest, farthest forward wet spot, and start your search there.
