hi, i have a 96 dodge with a 12 valve and im looking for anyone that has any tips for installing a pyrometer.
if anyone has done it and can post pictures or just help out id appreciate it.
thanks

 

use some grease so the metal shavings dont all fall in the hole and have a vacume on it. a magnet that will fit in the hole will help to get some out too. same thing when tapping.

 

Take your time when using Tap

 

 

Welcome to DB!!

 

And run the tap in 3/4 of the way - no more.


I might be able to snap a pic for you tonight.

 

are they all threaded the same?
what size tap do they use?
anyoneknow exactly where to drill the hole?
i know theres a serperator in the middle and theres parts that are thicker than other?
any help would be appreceiated

 

Depends on your thermocouple. Some are 1/8" npt (the preferred one), some are 1/4" npt, and some are post turbo.

The site I usually refer people to is down right now.

 

its a 1/8" npt fitting.
so it will be a 1/8 tap?
where can i buy anti seize

 

The bit should be letter "R" for 1/8" npt and a 7/16" bit for a 1/4" npt.

Anti sieze is available from just about any parts store - I like the Nickle stuff myself.

When I drilled and tapped mine I had a buddy hold a shop vac close to the bit and I cleaned out unside the manifold with a Q- tip with grease on it. Its best to keep out and many chips as possible.
