4 OF THE 12 valve stem seals slipped and were riding up the stems, thus causing oil burning and blue smoke.
Does anyone know where I can get the tophat style seals that will fit the old style 1992 cummins head?
I know I can buy the top hat seals that fit the new style head and 94-98 cummins, but they say it requires machining to get the seals to fit.
Does anyone know exactly what machining is required to make the seals fit?
Thanks
Dean
