Calculating torque to provide desired gasket compression was something I occasionally needed to do in a past life. However these were large flanges with special gaskets. Interesting finding was the torque required to provide the optimum gasket compression would not provide the bolting force needed to prevent vibrating loose (or the pieces not being able to provide structural support). If the gasket was critical, a compression stop was added so that the bolt could be torque to their limit without crushing the gasket And our "mechanics feel" saying was to torque to the GE procedure (Good Enough) Sorry for the ramblings, just reminiscing Joe -----Original Message----- From: DeTomaso [mailto:detomaso-bounces@server.detomasolist.com] On Behalf Of Larry - Ohio Time Sent: Wednesday, September 14, 2016 16:03 PM To: 'Charles McCall'; 'Himes, Terry (397C)' Cc: detomaso@server.detomasolist.com Subject: Re: [DeTomaso] Oil Leak Fixed.

What Torque? Terry - I can't answer your specific question as to proper torque, but I can offer some practical experience. I remove the valve covers every year as I have solid lifters and I check/adjust the lash once a year. I just tighten so it feels tight without overtightening - which I realize is neither a Metric nor Standard unit of measure - and I don't have leaks. I have blue Fel-pro valve covers, which allow a certain amount of compression. I just tighten it down fairly snug, by hand, without overtightening and I have never had problems.

Hey Pantera Guru's, I finally got to my Pantera last night. (work is getting in the way of my fun!!) Simple fix. ALL my valve cover bolts were loose. Every one of them. I tightened them all but didn't want to over tighten them. Anyone know what the correct torque should be? I have roller rockers and the taller Ford Racing valve covers for clearance. Your thoughts?
