Default Re-use old push rods?

I'm installing a new set of roller rockers (1.6/1) in my 91' L98. The car only has 35K miles on it, is it neccesary to use new push rods with so few miles? On the other hand a new set is only $50 it might be cheap insurance?

As long as there not bent, use em! Roll them on a clean flat/ true surface to check if you wish. I reused mine on my 91 when I went to 1.6/5 RR.

Hardened push rods only prevent them from wearing against the guide plates. If the new rocker arms are self aligning, like the factory rocker arms, hardened push rods are like throwing money away.

I was more concerned about bent rods, the motor shop said it isn't common but it does happen. Thats why I went hardened.

"Hardened" is surface hardening, which retards wear. Hardening has little to do with strength.

For me, the answer is simple. If my old pushrods were flat and passed a close visual inspection, I would send them back. No if's and's or but's about it. But I squeek when I walk.

If you're not changing the cam, why change the pushrods? You have nothing to gain with new pushrods. With only 35k mi, your factory set should not have exessive wear and shouldn't be fatigued (metal fatigue from too many miles--don't know if it happens with pushrods)

Roll 'um on a piece of plate glass...If they're the least bit bent, it will show up.
