On the Rally Bug, we burnt up a set of rockers (at the valve stem end) due to lack of oiling. This was on the first 2110cc, which is setup for drysump. We never determined *why* there was a lack of oiling for the rocker...could have simply been a bad set. But small oiling holes were added to the exhaust pushrods to spray oil inside the heads. No further problems.

I added the oiling holes on this motor out 'just in case'. I actually put them a little too far down the pushrod (was being conservative) but have ordered a second set to correct the hole position. As the push rod spins, it sprays a small amount of oil into the rocker area. At best, it's helping to lubricate the area. At worst, it's only removing a very tiny amount of oil out of the regular system.
