failed HFC install

Trips

can get in there and torch it off or a dremel with metal cut off disk remove the thread part of the stud and then use a nut extractor socket. I agree that one is PITA.

I could get that baby right off, happened to mine as well! I used a torch for almost a full minute over and over untill it came loose.

It's certainly the same bolt that gives everyone trouble.

Clark had the same problem with mine, but after removing the intake boxes and rearranging some things, he was able to get enough room to do his magic. Mine may not have been as stuck as yours, however.

I wish you were back in Augusta so you'd have the Performance Center to check out. I'd keep putting something like PB Blaster on it, and try it again next weekend. My buddy had a similar issue, so he just sprayed it every day for a week, and had no issues when he went to remove it.

Yeah Matt, I had the same issue with mine. It took both guys at Performance to get mine off. Ultimately, it took getting a torch in there and literally melting the bolt to free it up. I got some pics in this thread of it. HELP!! Rounded PITA top CAT bolt

Good luck, because I would have never been able to get it out. If the guys at Performance couldnt get it that way, they were going to take the header off.

Yikes! They torched that thing!

And I agree, the HFCs are worth it man! Don't give up!

Yea I always use a propane torch to loosen bolts. I first heat the bolt then spray some Liquid Wrench on the exposed surfaces and walk away for a half-hour. As the bolt cools it sucks in the Liquid Wrench into the thread area. When I come back in a half hour the bolt will loosen right out with just minor resistence. Has always worked for me for over 30 years.

Zsteve

I will ask them to try that.

Since your bolt is stripped my suggestion might not work as I was speaking to those having stuck bolts that haven't been stripped out.

However a suggestion for stripped bolts...I have at times used a punch and hand-sledge and tapped the stripped bolt inward a bit. Then I tighten up the bolt a bit. This can cause the stripped threads to recut. Then I would perform the "torch and Liquid Wrench" action. Then after the 1/2 hour I could then back out the bolt. This "hammering" trick doesn't always work however. I would say for me the "hammering" trick only worked 50% of the time.

Zsteve

Well Im not usre if the threads are stripped or the bolt head is just rounded out. I will have to check that when I get a shop to put it up on a lift to look at it. Im thinking the bolt never even turned for them.
