Use a torque wrench to remove them. If you get past 70nM then take a break and start thinking about penetrating oil and heat.

How much in ft.lbs. is 70nM?

52 ft lbs.

Use penetrating oil a few days in advance, then warm engine immediately before attempting to remove. You can run it with the IM off; will smell a bit but be OK.

GO SLOW.

Well, rather than luck, just never put too much torque on it, that always is the fatal flaw of over enthusiastic owners.

Keep us posted.

Good point. I've read about a dozen spooky threads here, so I am sufficiently spooked and wary. My arsenal also includes penetrating oil, a torque wrench, and anadjustable cordless impact driver.

I have teh heebie jeebies though. Back in a couple hours!

That little 5 mm allen bolt that holds the intercooler pipe to the EGR valve was a BA$TARD. Spent an hour on that.

Have the IM off though. The moment of truth....

Well, if you have the patience to spend an hour on the 5mm allen on the EGR valve, then maybe I need not worry about ham-fisted wrenching on the GP's.

Good Luck!

Ha, you spoke too soon. I managed to bust #4 off.

Numbers 1, 2 & 3 came out slick & easy. #4 was a bit stiff, but not nearly as much as #5 & #6. They all moved though, and I worked them slowly back & forth using penetrating oil. Leaning on the side of caution, I never went over 35 ft/lbs. I figured if I could keep them wiggling at that torque, I'd be all set. I took turns on those 3, giving each one a couple back & forths, then to the next one. I was working on other things, so I'd just do it every 5-10 minutes so the metal wouldn't get hot.

Of those 3, #4 was the one that was moving best. Then, it just busted off at 30 ftlbs. And it busted off at the head, leaving the shouldres still threaded in. Ba$tard.

Anyway, I've drilled out the threaded portion of the GP, and unwound the steel threads from the aluminum head. Threads still look OK. Now I need to drill & tap the GP body, and pull it out.

I can now see that they had previous trouble with that GP. The "nub" around the hole is a little beat up, and the threads are not quite "right" at the top. Looks like someone had crossthreaded one and then gone back to fix the threads. I don't know how you could crossthread one though.

Anyway, I have to find that thread where the guys shows how to make a puller. Fun stuff.

I vaguely recall a thread stating a particular brand of GP was beefier, I was thinking it was Beru, or was it the Bosch.

notfarnow - if you can give us the brand we may be further along diagnosing how others should proceed.

And sorry.

Thanks for the replies and support guys.

I was pretty much in shock when that one broke off, I wasn't even at 35 ft lbs. The only theory I have is that the threads were messed up (see previous post) and they may have ham-fisted it in there last time, weakening the "neck" of the GP.

The one that broke was a Beru with the mercedes benz logo on it. According to the records that came with the car, they were changed at the dealership by the PO 2 years ago.

I guess the good news is that it's a pretty easy one to get at for drilling and tapping. I think I'll make it OK.

As a cranky old buddy of mine used to say:
Gotta be an optimist, especially when the whole damn world is against you!
