Spark plug tube seals fail, causing the tubes to fill with engine oil and the engine to misfire. As a result, the engine may run poorly and fuel economy can suffer.

Steam cleaned engine with power washer while engine running. Observed car started sputtering an hour later then almost died coming home from work. Lacking power and acceleration. Next day checked spark plugs and distributor pack. Tried starting vehicle and could not get it to turn over. Did observe minor oil at base of 3 out of the 4 spark plugs.
