Your thoughts on pushrods, Stock or Moly?
Well in my infinite brilliance as some of you may know I missed a 2-3 upshift and hit 1st instead. It doesnt APPEAR that I have any damaged pushrods but I figured since I was in there I should replace them anyhow. Now the fun question: I did a search on this topic and it appears there may be two schools of thought: one saying I should keep stock in case I do it again so I bend the pushrods rather than something else. The other saying Moly rods are ok, did anyone ever get to the bottom of this? Any insight is appreciated..

I agree.....
With a stock cam there is no real reason to upgrade - saves you from bending valves instead.
Now, if you ever decide(or have) upgraded to a larger cam, then you'll need to make that decision - reason being, with a bigger cam you'll pretty much need to bump your rev limiter up. In bumping your limiter up you stand a chance of bending stock rods in the higher RPM's....thus the reason for stronger rods.

I'm thinkin about doing cam for sure and maybe heads, i was never aware of this bending of the pushrods and if i upgrade those then i have a chance of messin up the valve's instead. If i bought a set of complete heads, with the rocker arms and springs and everything, i shouldn't have any of those problems then will I? Won't have to worry about bending anything in that area, i'm aware i might mess up the rear end but i'm gonna go with a 9inch or 12bolt either before or after then, not sure yet.

Change the valve springs and push rods. The valve springs in your stock engine suck....they are weak and were not intended for high rpm operation. Go comp 918 with ti retainers andthe moly push rods and call it a day. Then if you decide to go to a cam you have future room for growth!!!1

best pushrods are IRP or Manton...the IRP's are my favorite...big in the middle & one piece..dunno what its made of but they are light & stiff, probly some variance of unobtanium

Again, just to give you a different point of view:
If you stay stock, I would not upgrade the pushrods. If you upgrade the rods you then are changing the "weak point" of the engine. Now, instead of the rods being the weak spot (which are pretty easy to change) you are now moving it to the valves.
I won't dissagree that in changing the rods you would strengthen the valvetrain some but if you do mis-shift hard the valves are the next thing to give......and I wasn't willing to take that risk/chance
I too, once upon a time, was learning proper shifting technique and made a few mis-shifts (3rd to 2nd). Bent some rods, which I replaced.....but never bent a single valve.
Good luck in your decision

well this is an A4, so I shouldn't have to worry about missed shifts. I think I will go be safe, and forge when something breaks. Gives me an excuse to upgrade Thank you all for your replies
