If it's on the '95 you should be able to unscrew the dipstick tube from the block and remove it completely. It can be a bear, I had to bend/strongarm mine a bit to get it in and out.

Re: New metal cam gear set issue.....help please

I had a Ford dealer install a Cloyes set on a 4.9l. They failed to press it on all the way. The cam was walking forward/backward enough that the fuel pump eccentric was hitting the edge of a lifter. It made a knocking sound at idle that got better over time as the lifter ate away at the edge of the ...

Yeah, it's a pretty mild Crower cam and spring combo so that shouldn't have been the problem. Pushrods were new Comp brand and they were the same end to end. Totally weird. On the bright side, it was an easy enough fix and the truck is purring like a kitten again.

Check your trans mount. On an 86 with a 4spd there's probably close to a 0.75:1 motion ratio between the fan and trans mount. If your trans mount is sagging considerably that would raise up the fan, maybe enough to touch the shroud. Good idea, I swapped in a ZF and the mount is relatively new but j...
