Cheap V-Band Clamps? Leaking.....
Cheap V-Band Clamps? Leaking..... What do you guys think?
Should there not be any black exhaust marks on the vband clamp?
The V-Bands are made by
Clampco
Paid like 18bucks each for them lol, so I hope their not crappy quality =).
Is there a torque spec when tightening down the v-bands? Maybe I am not cranking them down enough.

They have part numbers on them. 4 inch is like xxx 400 or something. 3.5 inch should be 350. You can figure it out by looking. Anyway if you have the right size, just crank down on it. If its tight, they really cant leak. Thats why people like vbands. do the flanges sit flush maybe they got warpped when welded??
As far as clampco there pretty good. Its a ss vband, ive never had issues, and i know a couple shops that use them without issues.

The lock nut will get noticably harden to tighten when you have tightened it enough. Be cafefull because if you tighten it to tight it will strip the threads and or pull the t-bolt out of the clamp...
I've tightened down tight as hell and then tried to loosen it to reposition and the bitch broke. The threaded part snapped with the nut still attached. I'd think that torque specs would differ between each clamp company if there is even a spec. I paid 10 bucks a piece for the clamps, cant really complain I guess.

Try hitting it lightly with a hammer all around the clamp as you torque it down, this will help get it positioned correctly and hopefully seal up. Usually they are warped though, need to be ground or next time have the two halfs clamped together and then weld.

The flanges are probably warped slightly from welding, it happens all the time. I would try bringing them to a local engine shop and see if they can surface the mating surfaces. To be honest that leak doesn't look all that bad either.
According to Clampco's website there are a bunch of different size v-bands for the inner diameter.

Leads me to believe I bought the wrong v-band clamps.
