marriedman Posted January 14, 2013 Share Posted January 14, 2013 I am hoping to be able to remove my entire exhaust in the next few weeks so that I can get the ceramic coated. Just some quick questions from some of you more experienced guys: I have been looking at the service manual that is hosted here (PDF pg 79 or chapter-page 2-23) and I noticed that there aren't bolts that go into the block, rather nuts that go on bolts coming out of the block. Is that correct? Are those gaskets where the pipe meets the blocks? Are they reusable or should I go ahead and buy new ones? My clamps look ugly, but sound. Should I go ahead and get new ones? Is this going to be a weekend job or a couple hour job? Any tips you guys have for a idiot like me would be appreciated! Link to comment Share on other sites More sharing options...

There are copper rings that seal the pipe. Get new ones because they crush when you put the exhaust on and tighten it up. 3. Have them coated along with the pipe? 4. Should be able to get it off in a couple of hours. 5. Spray all fasteners down with PB Blaster or something and let it sit over night. Link to comment Share on other sites More sharing options...
Veefer800Canuck Posted January 14, 2013 Share Posted January 14, 2013 I would add that upon reassembly, use stainless steel bolts with some anti-seize for the clamps, the original bolts will look like crap compared to the coated stuff. And the sandblasting has to be PERFECT! Right down to virgin metal everywhere. Sandblasting followed by a caustic wash would be even better. And some of my cylinder head studs threaded out with the nuts. I just went with it. Better than them snapping off. Anti sieze on all the head bolts/nuts on reassembly too! A little heavy grease holds the copper crush rings in place while bolting up the headpipes. Link to comment Share on other sites More sharing options...
marriedman Posted January 14, 2013 Author Share Posted January 14, 2013 wera803 - excellent info, just what I was looking for! Veefer - I remember you saying that the blasting had to be thorough, so I found this place about an hour away from me: http://www.afipowder.com/capabilities/ They were referred to me by a guy who does better than new restoration work on old Ferrari's, Pantera's, and other cars I never heard of before. They are supposedly known nationwide and yet reasonable priced. I talked to the owner (he actually answers the phone) and he said he never did a VFR before, so it would be $225. I said "Deal!"

Auspanglish Posted January 14, 2013 Share Posted January 14, 2013 Man... between Wera and Canuk they've said all I was going to say... some of my studs came out with the nuts as well... I too just went with it... also used a little grease to hold coper crush gaskets in place and kept a good eye on them to make sure they stayed symetrically centred while tightening up... careful tightening up bit by bit alternating from one side to the other... get the torque right. Getting the clamp bolts out can be tough... they can snap... and squeel like beeatches... plenty of anti-seize... get new stainless ones if possible and stainless bolts... in short...

Veefer800Canuck Posted January 14, 2013 Share Posted January 14, 2013 Oh yeah, X2 on retightening the head bolts. They use very little torque. I used my torque wrench. I wanna say like 9 ft/lbs, but that's from memory, you should confirm that. I tightened them slowly in stages, alternating back and forth, and each time you tighten one to spec, then do the other, switch back and do them again, because as the copper washers crush, you'll get more turns out of them, even though the torque wrench setting is the same. I alternated back and forth between each bolt at the recommended value until the wrench would click and there was no more movement of the fasteners at that value.

marriedman Posted January 15, 2013 Author Share Posted January 15, 2013 Auspanol & Veefer - you just reminded me of something important - I need to get a torque wrench! Do you have any recommendation for a specific one? From what I have heard at the Nighthawk forum, buy the most expensive one you can afford. But that doesn't tell me much.

Veefer800Canuck Posted January 15, 2013 Share Posted January 15, 2013 I have a couple of Westward brand torque wrenches. 1/2" and 3/8" drives. Clicker types, not the beam type, nor digital. They work fine and weren't too expensive. Link to comment Share on other sites More sharing options...
marriedman Posted January 15, 2013 Author Share Posted January 15, 2013 Haven't heard of that brand, where do you find them? Link to comment Share on other sites More sharing options...
Auspanglish Posted January 15, 2013 Share Posted January 15, 2013 I'm in Spain so I don't think my references will be of much use... got one at a local professionals tool/hardware store, can't recall the brand... Primus I think... it's a clicker. Link to comment Share on other sites More sharing options...
Member Contributer vfrcapn Posted January 16, 2013 Member Contributer Share Posted January 16, 2013 Haven't heard of that brand, where do you find them? How about a Sears Craftsman, reasonably priced and available locally. Mines lasted many years and is close enough for my work. Link to comment Share on other sites More sharing options...

Mines lasted many years and is close enough for my work. While they are still guaranteed, I have been sorely disappointed with the quality of the craftsman hand tools the last few years.

InTheRed Posted January 17, 2013 Share Posted January 17, 2013 If cost is no object, Snap-on makes some very nice torque wrenches. All the techs where I used to work swore by them. Link to comment Share on other sites More sharing options...
