Valve job on 3.0

Anyone know what the valve lash specs are for 3.0? Any information on doing it would be greatly appreciated as well.

Thanks

Thanks, for the reply and specs.

Is there any special procedure or can I just line up the cylinder and do the valve job?

I've been troubleshooting a rough idle and missfire for the past month and it's been driving me crazy. You name it I changed it.
I did a leakdown and each cylinder was leaking 4% to 8% not bad for 96k.
I cracked open the valve cover and checked what the lash is now, they are roughly .014 for intake and exhaust, but one exhaust valve in #5 cylinder was very tight, tight enough to keep the valve lower than the other exhaust valve. I loosened it up and temporarly adjusted it to .014, the car idles alot better.
I hope this was the problem, I'll know when I try driving it all day tomorrow.
So if anyone is has been trying to troubleshoot a rough idle and it's not EGR, IAC, distributer, wires, plugs, air filter, fuel filter, and the motor is good, try a valve adjustment.
I was told 3.0 didn't need a valve adjustment so I never checked it, now I know.

Thanks

Thanks for the reply.

Where can I get the repair CD?

I have the Helms for my other cars, but didn't want to spend for the one for the CL, you have to get two $$$..

Thanks
