Hi
Could anyone let me know what the normal idle speed is for the 4.0 sohc. Mines a 2000 year and once really warmed up, it idles about 500 to 600 rpm.
Seems a bit low. I'm planning on doing the OOM12 timing chain tensioner mod and am hoping the new gaskets on the intake manifold might help.
I'm hoping also that the low rpm is contributing to the timing chain noise at warm idle.. If I hold my foot on the gas and keep 800 rpm, theres no timing chain noise at all.
Any help or guidance would be much appreciated.
Great website guys - loads of good stuff.
Regards
Barry
