Like all the other parts that rub together when the engine runs, the valve rocker arms get a liberal coating of lubricant before installation. That's 3 places; the bushing that rides on the rocker shaft, the valve (flat) end and the pushrod end.
As an added precaution, we lubricate the valve stems (including the exhaust valve cap) and the pushrod ends.
This small cap (that I was referring to above) goes over the end of the exhaust valve. I don't fully understand its function, but I know it provides a little better heat transfer.
The rockers slip into place, almost. Note that these rockers don't have adjustment screws and lock nuts since the lifters are hydraulic.
It does take some push to get the rockers in place so the rods can be pushed into place.
Once the rockers are installed, a quick check confirms that the there is between .028" and .080" clearance.
When all the rockers arms are installed and checked for clearance, the valve cover gaskets can get a little sealant.
The gaskets are set in the valve covers.
The valve cover go on and the screws are installed and tightened and the cylinders are pretty much closed up.
Part of the baffling the comes with the engine requires that a long clip (pictured) span the cylinders. It is hold the baffle in place via a spring that must be stretched between the cylinders where you can't begin to get your fingers or any reasonably effective tool. A piece of wire is hooked over the end of the spring so that it can be stretched by hand. That's a hand that definitely requires a glove.
The opposite side of the clip (and held in place by the spring that is not visible) is the baffle. It's fairly neat a clean looking compared to the baffling I am accustomed to. It purpose is, of course, to force the airflow out through the fins of the cylinders on either side.
The accessory cover goes on next.
The accessory cover has a clean flat fit and lots of bolts.
We first run the bolts down with a lightweight electric screwdriver with a socket adapter. It really speeds things up in the whole assembly process. I have since bought 2 of them.
Inside the accessory cover are all those timing gears we installed earlier. The camera sees them better than the naked eye.
Careful inspection of the fit between the gears and the accessory cover is necessary only as a precaution. There was plenty of clearance on my engine and, I am told, this is never a problem. Nonetheless, it only takes a moment to check it out and, don't we do a lot of that when we fly airplanes? We only have one chance to check on these little internal parts and we do want them to be right.
The pre-bent oil return lines are easy to install.
It's really a pleasure to have something already bent to fit and they did fit perfectly. I'm tired of bending (and re-bending) my own tubing.
These oil return lines take the cylinder head oil back to the sump. And, NO! I am not standing on the ceiling!
This is just a final shot of the bottom of the engine where the oil sump attaches.
