[Healeys] high oil consumption

[warthodson at aol.com]

Bob, The owner is aware of the issues with oil & I think he is using 20w/50 Castrol synthetic oil. I will confirm at the meeting. On the trip to Conclave no one noticed any thing unusual about his exhaust. Some did say they say a "little black smoke, occasionally". I will be interested in seeing the plugs. If not rings, how else could oil be getting into the combustion chamber? Perhaps the valve stems could be leaking. How could we test for this? How about valve stem seals leaking?Gary H

 What brand/viscosity oil is he using?
 
 If it really isn't leaking it can only be burning it; I'd expect quite a bit of blue smoke out the tailpipe.  My BJ8's engine was rebuilt a couple years ago and uses some, less than this one, but isn't leaking it--I was under it yesterday--and I only get a little blue smoke after a long downhill run in gear.

 Our local AH club will be checking a BJ8 for high oil consumption this weekend. He says it is not leaking out. We will verify that when we inspect it.  He added 8 quarts of oil on the round trip to Conclave recently (2100 miles total). The engine was professionally rebuilt in 2011. The engine builder has recently retired & moved to a Caribbean island so we cannot contact him, true story. In 2012 he used 6 quarts of oil on a 5000 mile trip. About 2-3 years ago I checked the compression, performed a leak down test & inspected the spark plugs. Every thing was in the normal range. My question is: If the engine passes all the usual tests this weekend, what are some of the unusual ways you have come across that could cause high oil consumption & how would we test for them?
