A few weeks ago, I did CompCamsProMagnum 1.6 RR's & CM 614 springs, pushrods, & seals in Wagon. Put in new GM plugs (thru-wheelwells after removing splash aprons) & M1 5-40 oil. Did it all at friend's shop with him on a Sunday after opening things up Sat eve. Set lash at 1/2 turn. Sounds quiet, feels good, but I haven't driven car since done & want to give it some break-in before stomping on it. Did it 'cause I had some valve float before WOT shifts w/72K.
