Where to put a pyrometer probe in 1.6td

[Familydiesel]

Where and how do you place a pyrometer probe in the 1.6 td exhaust?  I am thinking of placing it before the turbo, but where does it go, or where is the best pace, and how do you do it?  
Thanks,
Greg

You're going to want to put it into the exhaust manifold pre turbo.  It's probably best to pull the manifold to drill and tap.

Where exacly is the best place to drill and tap the manifold?  Any place to avoid which is susceptible to cracking?
Thanks

Wow, thanks for the picture and the input.  Perfect.  Thanks

Added to the FAQ. :wink:

Damn, too slow on the draw! Oh well...

[Vincent Waldon]

Good stuff y'all.

Just don't even attempt it without taking the manifold off but that's where everybody puts them and it works great there.

wheres a good spot to put the probe on a VNT 17? i thought about putting it in my egr cover, but im not quite sure it will stick far enough into the manifold to get an accurate reading..

I got a VDO, EGT setup and am putting it in one of the bracket mount bolt holes:

 I saw this done over on the old board, can't remember who posted it and the picture isn't there anymore.


...and 1 more:
 

Does it look like it sticks far enough into the exhaust stream?
 I could probably grind off some of the extra threads and get it to go in farther.

Wait wait wait... So with this configuration you don't have to drill in to your exhaust manifold at all?  What motor was this on??

I would like to know about this as well.

Does one simply have to run a drill bit appropriate for 1/8 inch pipe thread tap thru the bracket bolt hole and tap it?
What year is that manifold off of?

thanks!

I would use a drill press. I tried to hand drill mine at first and when the bit dug-in at the end of making the hole, it cracked the manifold and I had to weld it...

Well if you used progressively larger drill bits it might reduce the risk of this. That's what I'd do anyway.

I used a number of bits to drill mine. I REALLY didn't want to crack the manifold.
LOTS of oil too while drilling.
