WTB Rocker arm 639614

[6597]

Looking for 1 to 4 rocker arms for small Continental, PN 639614 intake valve is common to C75, C85, C90, 0-200A & B. I can send to local aircraft engine shop for inspection/overhaul. This rocker does not have the additional oil squirt hole on the top by the valve stem. PM me with what you might have or know.

Problem solved, they are on the way, thx

On again, I need the rockers without the oiler holes by the valve stem. Prefer to trade for my existing extra exhaust rockers recently overhauled with 50 hrs.

Rick,

Have texted you a few times, you must be at Sturgis?

They turned out to be exhaust rockers with the oiler holes. I needed the intake rockers without the oiler holes.

Here's the difference

I have heard from an engine guy that the oil hole type rockers can be used for either side but must be on the exh. side. I would think extra oil would be a good thing, my 2cents. Call engine rebuild shop such as Western Skyways.

I think the problem is he's getting too much oil...

John is correct. Interestingly I was getting a fair amount of oil in the combustion chamber, either from the rings not seating in a timely manner or blow by or from the extra oil from the intake valve stem, who knows. For whatever the theory I did manage to get regular (correct) intake rockers and my issues are resolved. John and I aren't exactly sure what was going on and probably never will but the proof is in the pudding. I don't understand it but it worked. Sparkplugs are very much cleaner, no oiliness on any of them for a change.
