1999 Merc 2.5L 200 EFI. Serial # 0G883040
Motor locked up in September. Started tearing it down to swap my electrical and fuel components onto another shortblock. When I pulled the heads this evening, #5 and #6 pistons look like they weren’t gettingg oil. This motor was all original and still had the oil injection hooked up. Do I need to send my injectors off to be cleaned/tested? I’m planning on pre-mixing when I get the replacement put back together.
