Valve Spring pressure
Tuesday, April 08, 2008 4:43 PM
I am wondering on a stock 2.4L what is the spec for pressure on the valve springs. I had my motor rebuilt and they are just finishing up and the build was a little worried about the only having 40 pounds of pressure at the seating. Can anyone help? Thanks in advance

here's the link for ya... Valve spring specs

Looks like 50-55 lbs closed pressure and 122-133 lbs open pressure.

Seems as those springs are too weak

Here's the link for the ln2 motor. The 95-97 motors have a different rating than the 98-00 motors, kind of interesting. Not much of a difference however.
