Head/Rocker Cover Oil Return Seals.
Posted: Tue Apr 02, 2024 1:00 pm
The service is continuing on the Haflinger. Today was adjust tappets, replace spark plugs, refill with oil and start.
As usual I had trouble getting the rocker (tappet) cover on the passenger side of the engine back on and split the white oil seal that goes on the crankcase end of the pipe that takes the oil back from the tappet cover.
I went and searched my supplies and found two air filters (that I didn't need to order online but are coming tomorrow) but no white oil seals. I did find one of the brown similar oil seals that seal the cylinder head inlet and exhaust push rod tubes to the crankshaft. So I used it instead of the white seals.
Now I have something in the back of my mind that the white and brown seals are slightly different and the brown ones can leak if used on the rocker return pipe. So I put plenty of sealant around it to ensure it seals (I hope).
So is there a difference between to two - hence the different colours and part numbers or am I worrying unnecessarily about a pending oil leak in the near future - there was no leak on start but ..............
