EGR nut rounded off
92 EFI 300 6
so there i was, trying to take my upper intake manifold off. i realized that i needed to seperate the EGR valve from the intake manifold to get the manifold off. that little shiester is on there good. anyway, ended up rounding off the top nut on the EGR. anyone have any tips on how to get those bolts out? i suppose i could angle grind the EGR housing off and just buy a new EGR valve, but that's not cheap. i know you have drill out bolts and such but due to the location of these bolts it is not possible. so i look to FTE for advise. anyone have any idea as to how i can remove this EGR valve with the top nut rounded off? thanks.

Well I replaced my egr about 3 weeks ago and my egr valve flange was not threaded just the intake. On that top bolt maybe you could get some vicegrips to lock on it. Did you try some penatrating fluid like PB Blaster?
On mine it is easier to get to if I unscrew the brakets for my A/C line off of the cowl and move it down out of the way .
The tube on my egr has some play on it to slide it off of the rest of the bolt on my 1989 300.

Pipe wrench and maybe a tube to lengthen the lever arm - just an idea before breaking out the grinder.

i dunno how tight it is in there but how about using a dremel to cut a slit in the top of the bolt so its like a screw. except instead of trying to unscrew it the convetional way why not stick a big screwdriver into the slit horizontally that way you have alot more leverage. ive tried this and it does work just be carefull not to cut down to deep or u'll just break the head right off.

Whoa there........
Before you get all sideways there, take the upper plemum off WITH the EGR bolted on. That'll allow you to get it on a bench to work at getting the bolt out.
I say this from experience.......
Had to get Heli-Coils installed in the two same holes last weekend !!!!
Your biggest concern is (should be) getting the tube nut (from the exhaust) loose so you CAN get the upper plenum off with the EGR valve attached. Mine was a bugger the first time I removed it !!!
It's not as bad as it seems......
Take a step back and re-evaluate the situation.
If all else fails, take the upper plenum with the EGR on it to a machine shop. They'll get it all back to "nice and new condition" for a minimal charge.
Happy wrenching,
Bob

yea..i thought about just taking the whole plume off by removing the nut on the tube..but it feels like it's on there tighter that the EGR bolt. the problem is 2 fold. 1 the egr nut is rounded and 2 it's on there really really tight so your idea of the tube nut sounds better all the time. i suppose i could just get up in there with a pipe wrench and my 2 feet and yank that thing. wish my impact would fit in there somehow. thanks for all the replies!
