Hey all,
I'm sure this has been covered but I can't find it. My 88 Renix 4.0 has 230k on it and I've been slowly restoring/upgrading it.
I went to do the Valve cover modification and noticed a ton of gunked up oil on the rocker arms, valves, and pushrods. After removing and trying to clean the rocker arms and pushrods I resigned myself to buying new ones.
The new arms and pushrods (both Melling) seem to seat properly and torque down to the correct ft-lbs but when they're NOT under tension there is a lot of play. This play is mostly left to right rather than up and down.
I've double-checked the rod lengths and they seem the same as the originals.
Is this common on the 4.0 or is there maybe a lifter or valve issue?
Many Thanks,
Mickey85
