Do I need to add ZDDP to the motor oil for first startup with a new (reground) cam? I already applied moly assembly lubricant to the cam lobes. H23A1 motor, 260 cam grind, stock valvetrain. Thanks.

Can I re-use my lifters with the reground cam or do I need new lifters? They don't seem to be readily available for sale.1992 EX, 306,000 miles - Track toy - M2S4, H23A1, ST rear swaybar, Wagon brakes, GC coil sleeves, KYB AGX dampers, Stoptech pads, Toyo Proxes R1R, 2.25" exhaust

There are no lifters in an Over Head Camshaft setup.
Camshaft lobes ride directly on one end of the rocker arms and then at the other end there are the adjusting tappets that contact the valve stems directly (with appropriate clearances set). No lifters!Last edited by GhostAccord; 03-14-2017, 06:27 PM.

Sorry yes, I meant rocker arms.
They are about $40 each new so I seriously hope I can reuse the old ones.1992 EX, 306,000 miles - Track toy - M2S4, H23A1, ST rear swaybar, Wagon brakes, GC coil sleeves, KYB AGX dampers, Stoptech pads, Toyo Proxes R1R, 2.25" exhaust

You can reuse your old ones. If they have have flat spots on the faces though it wouldn't be a bad idea to send them off to Delta to have them reground. It's not too expensive, I think my H22A1 rocker arms were something like $6-9 a piece. But if you don't have the time or cash you can run them as is. Just for some reference though, jdm92_accorn grabbed an entire new set and it showed in the dyno over his old worn rocker arms, everything was smoother on the curves. You can see this in his MRT. A Delta regrind should yield the same thing as new rocker arms being it removes any flat/low spots.Last edited by Rilas; 03-16-2017, 07:53 PM.
