My question is for those of you that installed one of these valves. What is the best method for installation; just screw it in, use a pipe thread sealant, or use teflon tape on the threads??? Thanks! http://www.dieselplace.com/forum/smileys/Approve.gif

I didn't use pipe sealant but did swap out the fiber gasket with the OEM copper one. I have found the fiber type gaskets will leak over time. I've had mine on for approx. 20K now and no leaks.

I used some teflon tape on mine...

I used RTV on both sides of the gasket to seal up an cure. I've never had a problem with leaks using RTV.

I installed my Fumotos with the supplied gasket on my 85 6.2L and my 03 Dmax with no leaks. I suspect any leaks from either type gasket over time is the result of removing & re-intsalling. The Fumoto goes in only once & stays put, which should minimize opportunities for leaks.

I also installed mine using the supplied fiber gasket only. No leaks yet, but just installed it on Friday....

do you put thread tape/rtv/sealer on your drain plug? Not needed. As mentioned above, if it leaks, likely is was overtightened or under tighened. It only goes in once.

Eric,


I only put the RTV on both sides of the fiber gasket. Cleaned off the sealing surfaces with alcohol to get good and clean. I know it's not really needed however, I also know that I don't plan on taking it off and have had drain plugs leak in the past. Just a good practice I've picked up over the years.


Definitely not on the threaded areas. http://www.dieselplace.com/forum/smileys/Shocked.gif

Yup,used the supplied fiber gasket,No leakies !!!

Used supplied gasket, no leaks, no runs, no errors!http://www.dieselplace.com/forum/smileys/Evil Smile.gif

I thought the on/off lever would be at the 12 oclock position, mine's at the 6 oclock ??

POstion of the lever does not matter for the operation of the valve, its all just a matter of looks for it to be at the 12 o'clock position. Do not force it to the 12 o'clock position either, I have had a few customers do this and break the valve.


I trick for leak free is to install the valve and snug it up good. After a few days of driving it re-snug and you will be good. The gasket is kinda of hard and does not have a lot of initial crush. But once it gets heated up it will soften some and you will get a better seal after tightening the valve.

I just used the gasket washer it came with. No leaks so far but then again it's only been on for 200 miles.
