valve adjustment positioning clamp at #4 exhaust

Post by MikeysFiat »

Half done with the valve adjustment. ..waiting for the shims. The valve clamp tool works great, but the number 4 exhaust is hell if you don't know what you're doing the first time out. I searched the net and didn't find a good answer. Bottom line: remove the inboard cam tower bolt across from the distributor port. The clamp slips in from the inboard side. Pull the shim, read the numbers or mic it, slide it back in, then put the bolt back in and torque to 14 ft lbs. I didn't figure it out until an International Auto rep and I discussed the issue; he concurred. Unfortunately, I found no one on the Internet that posted an easy no-brainer solution. Most post only say it's a pain and you'll figure it out.
Suggestion: replace and retorque the bolt as soon as possible after removing and replacing the #4 exhaust shim. Put everything back together while waiting on your new shims to arrive. You never want to place sustained uneven pressure on the aluminum towers, they'll warp, unseal the gasket, and cause leaks.

Thanks for the tip, this is my September project...how did you turn the cams with a socket on the flywheel?

I was thinking of buying a whole tappet shim kit just so I didn't have to rotate the cams and pull the shims more than once, but it's a bit pricey that way.

Hi,

This didn't and never would occur to me.

Thanks!

I can't remember if my tool came from Vicks or IAP, but it works fine without removing anything, a little tight, but fits.
