WTB Rocker arm 639614
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.

Re: WTB/WTT Rocker arm 639614
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.

Re: WTB Rocker arm 639614
I think the problem is he's getting too much oil...

Re: WTB Rocker arm 639614
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.
