| Modern gasoline is not doing the aircooled VW engine any good! |
The aircooled VW engine is a classic engineering marvel - simple, robust, understressed - but it does run
hot, especially in hot climates. In type I and II engines, the #3 cylinder tends to suffer most. If there
is a failure, it is usually a burned exhaust valve in #3.
Lead in gasoline acted as a lubricant between valves and valve seats. Modern unleaded gas/ethanol
blends are very dry, with virtually no lubricating properties. Exhaust valve seat recession can result, a
condition where valve and seat materials adhere to and erode each other, with the valve migrating up
into the head. As this occurs, valve stem to rocker tip clearance is reduced. If this clearance reduces
to zero, the valve no longer closes, resulting in a burned valve. This means compression and power
loss, and ultimately a valve job and head replacement.
The Ampco VW top cylinder oiler, with proper lubricant, can reduce or eliminate valve seat recession,
adding thousands of extra miles to the life of your engine. The Ampco oiler delivers a mist of oil vapor
into the air/fuel mixture, thereby lubricating valve guides, stems, seats, cylinder bores, and compression
rings from the hot side - the heat/friction/wear zone. Auxiliary lubrication means reduced friction,
leading to a cooler, smoother, and quieter engine.
The Ampco VW kit is supplied with a carb sandwich plate which accepts the oiler nozzle, along with
new gaskets, longer carb studs, and nuts. Installation takes about one hour. Recommended lubricant
is Marvel Mystery Oil.
