My truck is blowin oil like crazy. It is coming out where one of the bolts is on my oil pump. There are five bolts, one top one, two long ones in the middle and two shorter ones at the bottom. It is leaking from the left middle one. I took it off and it looks like there is supposed to be a guide dowel (or whatever you call it) in that hole like the one on the bottom, but there isn't one. Am I right in thinking that or not? I am trying to figure this out right now so any info would be cool a.s.a.p. 1992 4x4 22-RE with 5-speed. Thanks in advance!
