So, I just squeezed in some Lucas Oil treatment for my engine oil, and in the process, noticed some lags in my engine that sounded like some internals were grabbing in some way. I'm thinking it's the conrod, crankshaft, or the needle bearings... The issue is that I've never opened up any engine, so idk what's going on with it. I know it has something to do with wear though. I need to get some replacement gaskets before I open it up. Any ideas as to what it could be?
