So I went out and it was acting weird while trying to accelerate so I stopped and realized all the engine oil had drained and I went in on the kicker. located a hole in the oil pan and patched it and refilled with oil and went out today and now its making a very loud clanking noise that gets real loud around 1300 rpm. the clank speeds up with more rpm and I tried to push throttle hard before noticing how bad the noise was and it has significantly less power. where do I start?
 
Ayuh,..... So what caused the hole,..??

If ya ran it outa oil, I'm guessin' the bearings are junk, along with the crankshaft,......
 
the hole was from a corroded oil pan. im assuming I messed up the bearings when I gave it power without oil
Safe assumption. Likely the engine is shot and needs to come out at this point. I assume you are seeing way lower oil pressure not only during the event when it started making noise but after as well.
