My 03’ Ranger with about 87k miles started knocking horribly on my way home. No oil in the engine even after oil change about 100-300 miles before, so that’s another issue. Right when I heard the knocking, I stopped driving and towed it home. Engine temp stayed normal and I have yet to inspect the oil.


I have come to ask how difficult/cheap/expensive it is to work on these engines such as replacing connecting rods and bearings (I assume that’s where the knock is coming from)? I have rebuilt inline 300’s and 2.3 Limas, but never a DOHC. I haven’t really seen much of an aftermarket/market in general for these so I’m not really confident In finding replacement parts.

thanks for your time- Joshua
