Permatex Black is good stuff for that.

This is a related question, so I'll put it here. I've always used the Red permatex, since it's high heat, I figure it's good for (nearly) everything. Is there any situation where you would want to NOT use the high-heat stuff?

I use Permatex as well, it's easy to get your hands on around here.

I think it's 3/8 but not positive. I know my local Autozone rents the fuel line disconnect tools and it comes with all of them.

I don't THINK there's a situation where the high heat stuff would not be applicable, and I definetly can't think of one where it would hurt.

Sounds like the same spot where I used Red permatex when I had to replace a head on my '99. Upper intake@cylinder head and valleys in-between. I think the black would work just as well. (I had a whole carton of the Red, so I just used that)

The fuel line disconnect kit I had several different sizes. I think it was 3/8ths tho...
If you plan on doing your own other future repairs, purchasing a kit wouldn't be a bad investment idea. As cheap as my kit was...($16.) its well worth owning. http://www.mytoolstore.com/kd/kdengi04.html

thanks, that sound like a good idea to buy the set, what set did you buy? There are so many disconnect tools, you say you replaced the head on you ranger 3.0, I do not have a dist. on mine. Is the camshaft position sensor hard to deal with any help.

Apparantly my web link notation never made it in my first post.

N-e how...
I just used the link for pictures and pricing. Mine is a K-D tool, but it doesn't seem to be listed on the site. I purchased mine from a local tool shop. I'm sure any real tool shop or automotive supply store should carry individual pieces or different kits for various applications.

I had a leak within the head (pssngr side) @ the back two cylinders. The truck was pumping/misting water instead of the full "explosion" that normally occurs.

Sorry, I never had to deal with my Cam Shaft Pos. Sensor... so I can't really help ya there...Sorry!

I'm sure someone else can chime in on the sensor...

DowCorning, GE, Permatex/Loctite all make good RTV products.

Not all rtv formulations are good for all situations. Some don't like to be in contact with oil products, others don't like gasoline & others have cure systems (acetic acid) (vinegar smell) & silicone, that are harmeful to sensors, like O2 sensors.

In general the oxim cure (sorta spoiled seafood smell) rtv's, are sensor safe, but don't bond as well as the acetic acid (vinegar smell) rtv's.

Just read on the products lable for it's cure system & use formulation claim to fame & choose the one best suited for your material, location, temperature range & system your trying to seal.
