Rembrant Posted December 27, 2021 Share Posted December 27, 2021 I have another weird question... So I bought this 1996 5.0 engine as a donor for my project, and unfortunately the original dipstick tube was rusted out. I snagged another one today from a junked truck...not sure what year, but a 90's F150 5.0. I know the tubes sit in the block the same on all of them...my 1984 302 was the same also, but I was curious...is there supposed to be a seal or an o-ring or something like that on the dipstick tube where it enters the engine block? I'm just wondering if there was a seal there at one time and it rotted away, or are they simply metal on metal from Ford? Link to comment Share on other sites More sharing options...
mat in tn Posted December 28, 2021 Share Posted December 28, 2021 so far i have not found one with a seal and most of the time i dont use one either but i have a time or two added a tight-fitting "O"ring no more than a 1/16' thick as long as the anchor point lines up well at the exhaust manifold.
