EGT gauge question.. Dumb question, don't hate

I couldn't do mine on the car. I took it all off. Mine is MK2 and I am big guy with no lift...You can put grease in the flutes of the drill bit and it will tend to hold whatever is normally coming from them. I rag and some brake clean and your drill returns to normal.

seems like the manifold would be hard to drill without using a drill press.

cast iron is super soft tho..

I did one for a friend and one for myself. I used a drill on one and a drill press on the other. Same bit both times. I would much rather do it on a drill press.

Someone, maybe saurkraut, on here said it was some variation of cast stainless. Cr 202 sticks to memory, but once again, I have no way of varifying that. It seems harder to drill than normal cast iron.

I drilled thru the existing mounting hole.  I drilled the threads out for 1/8 npt tap first so the bottom of the hole would guide the 1/8" clearance hole for the probe.

As suggested in this forum i angled the hole up toward the front so I wouldn't drill thru the flange corner.

I used a crap press, the kind that you clamp the drill on?  Without it I don't think I could do it as well.

Also, I tried first with HSS bits and they wouldn't cut, so I tried crappy tire titanium coated ones and they wouldn't cut so I bought cobalt ones and they worked awesome.  could be I just buy crap bits.

I heard that you can crack the manifold if the bit binds as it breaks thru so go slow and light at the end of the hole.

I put mine through the EGR block-off plate on my AAZ manifold. Angled the probe a bit, it sticks right into the #1 exhaust stream.

I'm still worried about it. But on the weekend, I will see if I have the proper drill bit, and tap, and see if I can make this work If not.. than I guess early next week, I'm going to buy a tap and drill bit.

I'm also worried about braking my exahust manifold. My freind has an mk1, and when he tried installing 2 on his car. It, was old and when he tried to work with them, they just cracked.. And I hope my old audi one will not brake.. My manifold was made in 84 after all!

I had no issues drillin mine.  some random bit i found in my tool chest, put my manifold in the vise and drilled by hand nice and easy.  Of course I had an extra mani on stand-by and the car was in pieces so I didnt take too many precaustions.

GL, its definately nice having an egt gauge

hate to thread jack, but I would like a CHEAP pyro, but would like it to work Im guessing thats a good luck kinda thing right?

I got one for $4 at the local used tool shop, and called it a win.

[billybobf]

dang for reals?

[theman53]

search micro 1000 and be done. Guage, probe, and shipping is under 100.00

I was pretty surprised when I threw the probe in the fireplace and it worked.

Well  . . . . . that's ONE way to test an EGT/pyrometer.
