I am thinking of going to the swivel foot rocker arms on my 1.7! I already know ,from a post here a vew days ago ,most of the advantage of that swap. My Ques. is : " Do they really make the valve train noise that much less" ? If that is true i will do it just for that reason! Those who have swivel foot rockers please Ans.

All of Jake's motors (AFAIK) use ChoMoly steel pushrods.
I use those in all of my motors for customers, but I have used these aluminum pushrods on a personal motor and didn't have any problems. Steel effectively doesn't expand with engine heat so your valvetrain starts off quiet (zero lash means no clack-clack) and as the engine expands with heat, the lash increases and the clack-clack gets louder. Aluminum is the opposite. It starts off with a gap which gets smaller as the engine warms up. But that being said, I never noticed a significant difference in the noise. |
