Sound Deadening Rocker Covers ?

[KiwiGT]

In a previous post I learned that my noisy tappets on my Roush 342R engine are a feature of an hydraulic roller cam + roller rockers. The 5.0 mustang Cobra of 94/95 used factory dual layer rocker covers with a sound deadening epoxy material to quieten down the rattling of the roller rockers. I would like to diminsh the noise of my roller rockers.

I live outside the U.S and don't have easy access to a Ford dealership to attempt to purchase the factory cobra covers (if they are stil available - I can't see them listed in the FRPP catalogue)

Can anybody suggest a source for factory or aftermarket sound deadening rocker covers to suit 5.0 AFR heads and roller rockers please ?

You could use the latemodel covers with spacers. Cast aluminum is going to be better than aftermarket steel.

I don't know why your valvetrain is noisy enough to be a nuisance. Hydraulic cams are typically are not. I have a hydraulic roller with '93 Cobra rockers(Crane rollers) and I can only slightly hear them on occasion, but usually I cannot.

Thanks. My rockers are really noisy - the engine clatters away like a diesel in the rocker area !

i presume the late model valve covers have the sound deadening material in them ?

I have never heard anyone say that they do and I know for sure that nothing prior to '94 did. Actually, I haven't heard that any of them have sound deadener.

My 302 has cast Mickey Thompson valve covers with no baffles and the valvetrain noise is faint at worst. It was the same way when I had stock '89 covers on it too.

your lifters should not make a noticeable noise, especially for hyd. cam. did you go finger tight +3/4 turn on the lash?

The 93 Cobra's 5.0 was the only application for these covers I'm aware of. Try Ebay. As for the noise, are you sure it's the valve train and not detonation?

I Wonder if you could paint them with something? Like a truck bed liner, although i dont know about the temps... but like previously mentioned are you sure you're not masking some other problem?
