What's This?
I know where is came from, but I have no idea what it's purpose is or even if it needs to be there. In tearing apart the engine I noticed this 'support' on the cylinder heads that covered the rocker arms. I noticed the left side had a crack in it. So I guess that means I need to replace it? But I don't even know if it is required for the rocker arms or what it is called lol.
Please help!

Oil dripper, no need to be to worried on the crack.

Glad I don't have to replace. Is this part critical and will it clear roller rockers?

Mine didn't clear my rollers so I was told to leave it off. It helps to deflect oil onto the oem rocker arm pivot balls. That's what I understand but I could be wrong.

Pretty well everything is covered correctly above. To the best of my knowledge anyway.

I have only seen this on a small percentage of Pontiac engines. It is an oil deflector, and it isnt really necessary. I would just leave it off. Most 1967-76 valve covers have drip deflectors over each rocker arm anyway. If you are concerned about oil staying on the rocker and not overshooting it, you can use crane "cool nuts". They are polylocks with grooves made in them for oil to run down.Summit and Jegs carry these.

My 1969 428 4 bolt main has those deflectors.

File it in the round file. Useless extra weight. Before I knew anything about my car I had mine brazed where it had cracked, told some Pontiac people about that and they laughed. It really just gets in the way.

Years ago I had a terrible rattle underneath my valve covers on my '69 GTO,took one side off and that baffle was all cracked and broken up?I ended up taking both sides off the heads!

I was hearing a clatter from time to time coming from the left side of the motor. Maybe this could have been the cause? Either way I don't think its going back on!
Thanks guy! |
