Do The Torx Bolts On Egr Valve Snap Easily?

[smartme]

Just wondering if the two torx bolts that hold the little metal pipe on the EGR valve break easily?I'm just about to loosen them so that I can pull the egr off and clean it all. The right hand bolt is a littlerusty and I just get that feeling it will snap. Happen to anyone before? Seems like such a big jobif it snaps to fix it again.

You mean the EGR cooler pipe that's going into the EGR housing?Won't do any harm if you spray a little penetrating oil a few times before you start the process.

The only way I managed to get the last one I did off was to use a oxy acetylene torch, had to remove all the hoses and other flammable stuff first.Canman

Yeah, just as I thought, what a bummer.

I get the feeling the oil won't be enough as it looks very rusted.

When I did the EGR delete on my cabrio, I actually had to cut the head of the bolt off with a small zip disc...On the other hand, the bolts were actually loose on my coupe...

A simple cleaning can be done in place.

If it's too far gone you don't need those bolts removed intact anyway, you're changing out the valve or blanking off and emulating.

BTW, I've removed many broken-off studs in my time. If it has not been hacked and mashed at, once the pull from the component has been removed you can almost always get the broken stud out. If in doubt get it to a professional (not the dealer!), before the bolt is broken off flush, when it's easy and virtually 100% chance of success.

At times when I fear the worst, I will deliberately grind the head off an unbroken stubborn bolt, just so I can work on the stub free from the component, reckoning that the expensive casting is worth the extra time to ensure it remains undamaged. Once the bolt is broken off flush it gets much more difficult to ensure clean removal.

Thanks for all the tips! Luckily, when I actually tried to loosen the bolts today, they turned with almost no effort. Seems even though they looked bad, they weren't even very tight, so I feel good about that. Now to the task of cleaning the egr valve and getting my wife's smartcar on the road for Summer. I'm hoping by cleaning the valve that the motor will never go into limp mode again which is such a PITA when driving.

If it's been sitting long you should service the waste gate too, they tend to stick and cause limp mode.

Sorry for the late reply as I was away a couple of weeks. Yes, thanks, as per your suggestion last year I didclean the waist gate, but that alone did not stop it from going often into limp mode.I managed to pull out the EGR valve today and it was almost caked shut from all the carbon. Even sothe valve itself was still moving fine, but I'm hoping that after cleaning it all out that the annoyinglimp mode won't happen again.

Delete the bugger, problem solved.

Can you provide a link how to delete it! I know I read something about that before, but can't remember where.

Hi. The easiest way is to buy a kit from http://www.ebay.com/itm/EGR-CHEATER-BLANKI...=item2a2f34b6acIt comes to your door in a week or so. Installation is simple and quick. I have used plate and gasket to block exhaust pipe going to EGR and plugged in simulator. EGR intact left in place (you don't need additional connector pipes). I am driving with this mod for over 30000 km with better power and fuel economy. Sweet, it works perfect.

Thanks, will take a look and learn something new!

Hey, thanks for that info! The simulator shows 4 wires. Do they need to be spliced and is it complicated?

[Francesco]

While digging for that tail lamp last night I found that I have one stainless EGR-delete pipe left, the original prototype that the machine shop test-fitted to my car to get the cuts right. Let me know if you're interested in it. It comes with two sections of silicone tubing, you just need to supply four clamps of suitable size. $145 shipped anywhere that FedEx delivers in Canada.

The simulator has 5 wires (There is a black wire in the middle). It comes with the instruction. Edited July 16, 2014 by Jerzy

Is it a simple install with the wires?

Thanks. If I decide to get one, will pm you.

Yes it is simple. You have to make a connector with an EGR plug. I have soldered pieces of a paper clip to wires and bent them into a U shape. To connect them just follow instruction which comes with an emulator.

Thanks. Not sure I should buy their product though if they leave out an important step of providing a finished connector.

[FlossyTheSmart]

The connector required would need to be custom made for this purpose. The "normal" install would be to cut the connector off of the wiring harness and splice the emulator in place of the connector.
