Frank Zappa · Dec 13, 2003

The girl I want (but that's another story) just got a 92 Cherokee from
her mother-in-law, and the dipstick tube is loose and leaking where it
enters the engine block. Can this be fixed with some JB Weld, or does
it have to be replaced? And can I do this myself, or is it better to
let a nechanic do it? It sounds routine to me and probably is but I
wonder if there's any quirks particular to Jeep. The engine is an
inline 6 w/ 5-speed trans.

TIA

Pull the tube & if it's not DRASTICALLY loose, clean it, RTV it (red,
black or grey), reinstall it, let sit overnite, problem solved. It
should have a mounting bracket somewhere upstream to support it. If
not, find where it broke off & weld it back on. If the tube is
unsupported , gluing it in will be a short lived fix. Good luck.

The full name is RTV Silicone. Sold in tubes, like caulk, as
an adhesive/sealer.
RTV stands for Room Temperature Vulcanizing.

I would use the JB weld myself.

Be very careful about using RTV on a newer vehicle. There are two
types, the 'regular' RTV silicone who's fumes will destroy the O2 sensor
in a blink.

You need the more expensive 'sensor safe' RTV.

I can't recall seeing non-sensor safe RTV in a long time Mike, is it even
still sold?

Room Temperature Vulcanizing. Silicone adhesive.

I could swear that the things are mounted with some sort
of glue, but in two different engine rebuild manuals, neither
mentions how to secure the dip tube in place. Would guess
the secret will be picking an adhesive immune to hot oil
as well as one that can create a bond in spite of any
residual oil in the bond area. I'd probably spend a
cuppa coffee or such on a local dealer service manager
or engine rebuild tech.

That sounds like a good idea. What's coffee?

I've never seen a tube labeled "non-sensor safe" but I have seen them
both with "oxygen sensor safe" or no mention of a sensor.

I sent a friend up to Canadian Tire for some RTV and he sure managed to
find the 'regular' RTV easily enough, seeing as that is what he brought
home.

The permatex 'ultra' line of RTV is the sensor safe one.

Nah, don't ask those guys, they don't know ****, and they are as dishonest
as they come.

Gotcha, that makes sense Mike. My local store only carries the Ultra stuff
so that must be why I only see the sensor-safe stuff. Thanks for clearing
that up.
