EGT Gauge question
Howdy,
I just got my first diesel truck in April and I will be doing a lot of towing come fall. I want to install an EGT, Boost, Tranny Temp gauge on my truck, but I heard you have to drill into the header to install the EGT probe. If this is true, how do you drill into the header without getting metal shavings inside that will end up going through the turbo. Like I said this is my first diesel truck, but I would think even tiny metal shavings + turbo would be bad.
Thanx,
Roach

You will hear all kinds of suggestions from putting a magnet on your driil bit to putting grease on the drill bit to hold the shavings, But when I installed my EGT gauge I removed the exhaust manifold to drill and tap the hole. It's really not that difficult to do, only 10 bolts plus you have the piece of mind knowing that no metal shavings are headed for that turbo.

I drilled mine without the grease on bit and just vacummed out after I got the hole drilled. I keep hearing about the danger of metal getting into the turbine, but I have never heard from anyone that it happened to. If you are concerned with it, just before drill goes thru, start the truck and finish drill the hole. Just too much bother to remove the manifold. What happens if you break off a stud?

I was nervous installing mine then I read a response from Ryan (the self proclaimed a-hole) and he said not to worry about it. He felt that little shave will be blown/pass through the turbo with no problems.

A drill shaving will not mess up the turbo, quite often pieces of valve make it past the turbo without damage. If you drill it running and tap it running, you will mathamaticly have a better chance of winning the lotto than damaging your turbo.

One thing else that many forget to mention. When I drilled mine, I noticed that it was not a cast iron manifold. When drilled it made shavings like cast steel or mild steel does,( long curled shavings) not little chips, like typical cast iron. In any case, both still follow the laws of gravity and physics, which when the motor is running and the manifold has positive pressure on it, the chips cannot go in the manifold, they blow out and fall to the ground. Even in your eyes if you are not wearing saftey glasses. I just don't know how much more complicated one can make this 5 minute proceedure.

When Banks installs the probe at their headquarters, they leave the manifold installed and drill and tap with the truck idling. Their DIY instructions tell you specifically to Remove the manifold then do the work. Itsa Liability thing.

on my 2006 i drilled and tapped the manifold without the engine running, i used a small magnet to get some of the shavings out and i udes a 1/4" piece of copper tubing taped to the shop vac hose to suck the other shavings out, check my gallery for pics of my pyro probe and gauge install..........
