Vacuum leaks suck Reply #15 – September 05, 2012, 02:30:52 PM Quote from: TOM Renzo;397010Clearly it was cracked with a uneven clamping force to crack the EAR!! Like i said those gaskets are a bit to be desired. Aftermarket GIMMICKS are loaded with faults and can and do mess up engines. This is from many years of experience. And why the insulator. Really what does it actually do?? I would think NOTHING!! As far as torque specks i can look it up but is has to be around 20-25 FT/LBS. This is enough to break the ear with uneven gasket compression. I would love to mike that gasket for uniformity. Grab a one inch mike and see if that gasket is uniform. I am willing to bet it is not. Many many years ago i learned about things like this and i learned the hard way. Stay away from GIMMICKS. What is wrong with a stock gasket any way??? Just me and my $.02 I need the spacer to clear my valve covers otherwise I wouldn't use it as they don't do anything to increase performance. If I don't use the spacer then I can't hook up the throttle cable to the throttle body as there is no room. I do have a good spacer, made by Ford Racing out of phenolic material, not a cheap Ebay one. The reason that the intake cracked is not the spacer's fault (it's perfectly flat) but my own. I used the torque spec for the stock HO upper intake when tightening the bolts, which is 20 ft/lbs. The GT40/Explorer intakes require 10 ft/lbs, so I basically doubled the torque the mounts were designed to take. That's what caused the problem. I do agree that there is no point to using this spacer if you don't have to. It doesn't increase performance at all and can lead to a cracked upper intake mount. In my situation I have to use one so I bought a quality piece, not some cheap ABS plastic off Ebay. Quote Selected

And then check with starting fluid or brake clean "1001 uses". To see if it's sealed. That is a weak spot on that intake.I tighten mine with a 1/4 drive ratchet. Very difficult to over torque that way. Quote Selected
