pyro guage

[livnlrn]

My guages were in my truck when I bought it. I'm getting ready to install new exhaust, and noticed that my pyro. guage line was in my pipe behind turbo. How much diff. in temp. readings does this make versus having it in the manifold.

[strokin_early_99]

Anywhere from 250*-450* depending on the load and the right foot.

When you replace the exhaust put the probe in the manifold.

whats the easiest way to put the probe in the manifold?

Drill and tap it...

I also
Agree with strokin...

[Dirk]

drivers side, bottom. Drill and tap. You should have plenty of room with that lift.

Is there any special way I should drill the manifold, besides taking it slow? I dont want to get any shavings in there.

[Dirk]

SLow and steady. Keep the drill straight. If you do this, very few shavings will get inside the manifold. When you start the tap, make sure you are inline with the hole and make a smooth even turns. Do not press hard on the tap, let it pull itself in. Use anti seize or keep spaying wd40 on it. The cast iron is soft so it will be easy to turn.


Also, wear safety glasses.

Also when you are drilling and tapping if you put grease on the end of the bit the shavings will stick to the grease.
