Default They bend so easy?

With all this talk about bending pushrods so easily i have to ask. With the hardened pushrods I installed along with my cam and springs, could I have bent any from a WOT 3rd to 2nd missed shift where I went to hit 4th and obviously hit 2nd instead, BUT I didn't fully let the clutch out as the clutch pedal was about half way off the floor and the tires lock up a bit and the tach shot up to 6800 rpms, I immediatly pushed in the clutch. I know that if I fully hit 2nd and with the gas pedal floored, it would do damage, but how about when I am almost off the gas pedal and only let the clutch out halfway before noticing it? THis was when I was making an A tap run <img src="gr_images/icons/mad.gif" border="0">

If it were MY car, I'd pull the valve covers and check. It doesn't take that long. You should definitely notice "issues" if you bent anything, however.

Default Re: They bend so easy?

I recently had my motor replaced...and upon hard acceleration, mainly from 3rd gear up...i head a rapid tapping noise coming from what sounds like top of the engine. Sort of sounds like what my other engine sounded like when it was starving for oil...but my new motor is full of oil. Do you think the lazy bastards at the dealership would have put in my old bent rods into the new motor? Thanks (sorry for jacking your thread, related question)

I did the exact same thing. Although, I went from 5th to 2nd on accident with stock pushrods. No bending here!!! <img src="gr_grin.gif" border="0">

at the dealership, they only install Complete motors, w/valve covers and most of the time intakes. At least where I worked. <img src="gr_images/icons/cool.gif" border="0">

It is a lot harder to bend the hardened pushrods than the stockers? I would pull the covers and check it out but it is kind of a PITA to pull off the rockers and them torque them all back down, I am not usually lazy but I just got down doing headers <img src="graemlins/gr_barf.gif" border="0" alt="[barf]" /> I haven't heard any weird noises. I am just wondering if anyone has had a simila experience with hardened pushrods and if they bent.

UNLESS you really have a wild cam and wild springs
I would not go with hardened push rods. They
are like fuses for you engine. If there is a problem they will bend. If they are hardend then
"Mr valve meet Mr Piston" in a big way. The weakest part normaly the valves will bend then.
This costs much more to fix than a $11 dollar
push rod..
I changed mine like this.

Oh missing shifts with M6 ..get a ripper or pro-5.0 and that wont happen unless you really
try

i am from the camp of run stock pushrods too. Rather replace a pushrod than pull the head and see some valve to piston action, bent valve, etc.

stock pushrods are cheap and easy to change...could change them at the track if need be.

I got a set off ebay for like 15 bucks I think

If you really only revved up to 6800 you should be fine.
