Installing Egt prob tommarow PLEASE HELP !

[clndesl]

I have been reading all the other post and i am not sure what the best way to drill for the probe pre turbo. On my last truck my friend just left my truck idiling and drilled away it seemed easy and i had no problems at all. After reading all the other post i dont know if this is a good idea. Please let me know what you guys think.

I've had three trucks and all on them I drilled the exhaust will the manifold on the truck and the turbo on the manifold. Most of the shavings are going to come out of the top. Only a little goes through to the inside of the manifold. Those small pieces won't damage the turbine wheel. They may get blown through the turbine wheel before it even starts spinning. Besides, after drilling you could stick a magnet through the hole and get them as well. Now, drilling the intake for a boost gauge, hands down, take the intake elbow OFF.

I put grease on both the drill and the tap, and as RShipp sugests, I stuck a small magnet in and ran it around. Didn't get much with the magnet though. Drill and tap and don't worry about it!

Here is what I did.

If you don't have an angle drill, I remove the right front wheel well plastic. I drill to about the break through point and grease the drill bit and slowly drill the hole through cleaning the bit a few times. I have done 5 trucks this way and have NEVER had any problems down the road.

yep. . I just moved mine and did it that way. .

I don't suggest using grease, it doesn't allow the chips to fall away, they stick to the grease. . then what happens when you get a glob of grease that has chips and it falls in the manifold. . when it gets hot and releases the chips the turbo is spinning and you run the risk of damage. .



Any dry chips that are left in the manifold will be long gone before the turbo is spinning fast enough to cause damage.

I used a buddy. He held the shop-vac while I drilled the hole, then used a magnet to get out the rest. Worked great. No grease mess needed.

I happened to wait until my turbo was off for work and drilled till my heart was content. Not too much falls into the manifold anyway and what was there was easy to get out with the turbo off. My point is if you're considering a turbo upgrade in the near future wait until then, otherwise it shouldn't be too much of a problem. Less than you probably think ends up in there.

I did it, so anyone can do it...



- Center punch the location. Near cylinder #3.

- Take your time and don't rush.

- Drill in 3 stages up to a size "R" drill bit. Clean w/shop vac as you go. When you get to the largest bit, take a telescoping magnet and move it around in the hole as much as you can to get the shavings in the bottom of the manifold tube.

- Use a 1/8NPT tap and tap oil. Go 1/2 turn in, 1/4 turn out until you make approx 5-6 threads.

- Use the magnet again. I got alot of shavings with the magnet. (each pic is a different swipe in the manifold)

- Use high temp anti-seize on the probe threads and ensure your probe is midway into the exhaust tube. Diprocol probes are not adjustable, you need the shortest probe they make for the exhaust manifold. (p/n D 192 116) If you use p/n D 192 100 (med length), it will bottom out in the exhaust manifold.

Looks Good.
