EGT Probe Installation

[MKeeney]

I know this is a subject that's probably been done to death here, but this forum software isn't very good at searches so I'm stuck with having to ask.

I have an early 99 F350 with a 7.3 PSD. Is there a pre-drilled spot on the exhaust manifold before the turbo, or even on the turbo, that I can stick in the EGT probe, or am I going to have to drill and tap it? I'd rather not have to do that so I'm keeping my fingers crossed.

Sorry man, gotta drill and tap it. Getting ready to do this myself. Think I'm gonna do this under the truck on the driver side manifold. Gonna try to get the hole as close to the bottom of the manifold as possible so sucking out the shavings with a vaccum will get most of it out. Don't want that stuff going through the turbo!

yea thats excatley how I did mine not too hard of a job.

Drilled & tapped mine. If I can do it you can do it...

Between the vacuum and a small magnet that will fit in the hole, that will get pretty much all of the shavings. Drill slow and wear saftey glasses!

It's the "get MOST of it out" that always worried me, that's why I pulled my Y-pipe and tigged on a stainless boss for my EGT probe. I think next time I have things apart I will tig on a second boss so I have an EGT probe for each bank of cylinders hoping it will give me an indication when an injector is going bad

Doesn't the way you did it only take a measurement from the one bank then? It's basically 'no big deal' to do it like that? It's my first PSD so I'm trying to be gentle.

yup, only reads one bank of cyl. Need to do this to my red truck... and the work van for that matter...

I too was scared to drill and tap my manifold, but after doing it, all I have to say is that I should have bucked up and done it sooner. It really is much easier than you think it will go. Drill up, go slow, wear safety glasses. Tap the hole, then start the truck to blow out any shavings. Then screw the fitting in. Done. Should take 10 mins, and most of that is getting the tools out.

Yes, I guess you could do it in the up pipe, but the farther from the cylinders you get the less accurate your reading is going to be.
