Can you hone out a stock EGR spacer?

[LarsD]

I have an Explorer TB that is supposed to be 65MM, I can adapt that, but it won't do me much good if I still have the stock sized EGR on it. Can I hone this sucker out to 65MM safetly? The coolant lines are gone. Also, what could I use to hone it out?

Thanks,
L.D.

Check my sig. I used a mill and boring head to do it. Most people dont have access to those. And yes it is safe.

You could try it with a Dremel, but it will look like crap unless you spend alot of time on it. You might as well buy one if thats the case.

I was thinking about trying to use a ridge reamer, LOL!!

do you have a cylinder hone? I've used one before to do this, but you have to use plenty of oil to keep it from loading up on you. the hone always worked for me

No I don't have one. I can borrow one from Autozone right?

You need a lathe with a boring attachment or a milling machine as stated before. I was selling bored TB's and EGR spacers on ebay a couple of years ago. A hone will not cut as will the bit from a boring head or a boring bar.
I have a ton of TB's and EGR spacers in a box in my shop that are already bored out. I just lost interest in selling them.

I cut mine to 67mm on the lathe with no problems. Anything more than that I would worry about air leakage.
