I removed the intake manifold to change the gaskets (I have another thread about coolant in my oil after manifold swap on my 318 Poly). I was scraping some of the sealant off the head with my cheap hobo freight scraper (see picture) when I dropped the plastic cap/cover down the lifter valley. Initially I could see it. I tried retrieving it gingerly with some forceps and of course I dislodged to some place I can't see or access. Any advice? Where will it end up if I do nothing? Oil pan? Mangled by the crankshaft?
