FLGS400
I'm Awesome
So, I decided to put a mechanical temperature gauge in my 1991 C1500 with the TBI 5.7. I wanted to keep the stock temperature gauge functional, so I am using the 3/8 NPT port in the passenger side head, that was plugged. I bought the square socket to get it out and it rounded out the square. Needless to say, I tried a bunch of things over the past couple weeks, to get that thing out. I ended up having to drill it out and re-tap the hole. Now when I install the 3/8 NPT adapter for the probe, it screws all the way in to the back side of the 5/8 tread side by hand. I'm pretty sure that is is going to leak as that is way too far for an NPT fitting.
Before I damage this thing any worse, I was looking for opinions for you all of what the best sealant I could used on the threads would be. I would really like something that will seal the threads, and lock the fitting in place without applying too much force to the adapter fitting (like finger tight). I considered JB Weld and a Permatex thread lock/sealant (supposed to be of the "blue" thread lock quality), but thought I would ask first...
Anyone have this problem before?
