Leak around base of dipstick


Recommended Posts

Hey guys,

 

Chasing a leak. Looks like the source is from the base of the dipstick tube (arrow in the first pic). I searched the FAQ and the only recommendation I saw was to put some sealant around the base of the dipstick tube and jam it in there.
1. Is that a viable solution?
2. If so, what type of sealant would you guys recommend?

3. See second pic, it looks like there might be a groove down in the hole in the block. Not sure if that's where the tube bottoms out or if there's supposed to be an o-ring there. Just rebuilt the motor last year so would rather not drop the pan, but willing to do so to fix the leak..

 

Thanks for the help.

There were several different dipstick assemblies used on 2002s; yours is definitely not the early style with the cast aluminum base that screws into the block.  However, the parts book shows several variants of the steel tube that's a press fit into the block, similar to your picture. 

 

Go on realoem.com (or check your factory parts book) and look at page 11-44.  At least one of the three dipstick tube variants use some species of tubular clip (parts book calls it a "double taper ring") to help wedge the tube into the block.  However, this ring goes with an externally threaded "cap screw" through which the tube passes through--and your picture shows no threads inside the dipstick tube hole.   Thus I suspect your dipstick tube is one-piece tube that's pressed in to the block, or the two-piece tube that's joined together with a section of rubber hose.  Neither of them use any kind of fitting or seal where they enter the block, just a press fit.  

 

If the fit on yours is loose, you might try taking a tapered punch and gently expand the end that's inserted into the block to give it a tighter fit.
