Pushrod seals...and adjustments.
- Thread starter Deathstar88
- Start date
big inch motors are going to tick, that is a given. roller rockers are going to tick, that is a given (but better for performance and wear). adjusting the pushrods will quiet them down , to an extent. it will not get rid of all the noise. remember, in a car there is insulation between the motor and you so you do not hear the ticking as much. so there has to be an "acceptable level" that you will put up with.
or you can go buy a Honda.
as far as replacing the seals goes, somebody that has done it needs to speak up. i haven't had to do it yet.
*just to clarify something, almost all of the 117's, and pretty sure most of the 107's, came with non-roller rockers. i was referring to the possible thought of replacing with rollers to help quiet down the tick.

I changed my seals because they were pinched and oil was getting on my exhaust. I guess my question is, where are you seing the oil? If the answer is on the push rod tube keepers, it would mean that you have a worn or pinched seal. If you mean on the push rod themselves, thats normal...

what is a push rod keeper? i see oil on the pushrods themselves.. How often should pushrod seals be replaced? and how often should they be adjusted?

the pushrod is a solid steel rod that runs from the cam to the rocker arms. the rods are inside the pushrod tube, the bottom half being chrome,all of which collapses to the top so the pushrods can be adjusted at the bottom. the pushrod keeper is the chrome piece of tube that snaps back into the top half of the pushrod tube to keep it all in place and allow the oil to run down the pushrod to keep it and the cam lobes lubricated.
simplified, but i think that covers it.

Give me a call if you need to be walked threw it. Your only an hr and a half away from me or so...
In order to replace the O-Ring seals inside the pushrod tubes, your gonna have to take the rocker boxes apart. You have to do so because the Pushrods themselves have to come out in order to get the tubes out and replace the $10 worth of O-rings
Normally you will not have to do any adjustment to the Pushrods unless you have replaced lifters (tappets), cams, collapsed the pushrod itself, ect...so if non of this has been done, you can just mark the pushrod itself as to location (ex: Front Intake, Front Exhaust, Rear intake, rear exhaust)
If you get them mixed up for some reason, you can go off the length and I'll have to go over that with ya.
There is an adjustment procedure to them as well and you will need to make sure you don't have hydro solid lifters.
FYI, some of the early motors with the TP style rocker boxes did use Roller style rocker arms. Ones BDM started buying the motors complete from S&S, they did away with them.

Pushrod tube keeper = the upper portion that clips in, and keeps the tubes from collapsing.
Never, unless they're leaking.
Never, unless they're noisy. You have hydraulic lifters. Set them once PROPERLY and forget them.
Tinkeritis will ruin sh*t all the time. :bang:
