lol? are you serious? your using a tourqe wrench on valve cover bolts? i guess thats what you would use if you dont mechanic every day. after awhile you start to learn what the diffrent poundages are. i could tourque headbolts without a tourque wrench i do it all the time and not once have i ever had one come back. (allthough i will say its not the most professional way to do it.)

Torque wrench? Is that the thing with all the dust on it in the bottom drawer of my toolbox?
I use a 3/8 ratchet and get them Guten-Tight.

I'll make a wager that your nuts are nowhere near the specified torque and you run the risk of leaks below the gasket or twisting of the cover itself. That torque on that valve cover is critical due to the design. It's a classic case of a mechanic who thinks he's got more knowledge than the engineer who designed the fastener. All too common, unfortunately.

I totally agree with Brian, it's kind of important when it comes to gaskets that torque be not only even but to spec. I used to think less of this until I bought set of torque wrenches and went back to work I had done and then seen how poorly I had been estimating it. This past weekend I went to put a new VC gasket on a 617 I recenlty bought and the nuts were so tight I almost had to use a breaker bar on them to free them. The bolts that held the linkage down needed a breaker to get them free - I was afraid the VC itself would break before they loosened. Whoever had previsously done work on that car surely didn't use a torqure wrench which is probably why it needed a new VC gasket anyway. I had heard the spec was 10NM not higher than that though, so someone ought to double check. It sounds like they are using 10ft-lbs which would be around 13NM, probably wouldn't make that big a difference but I think the spec is only 10NM.
