This is a lot of work but could contribute to the seal failure. The oil drain going to the oil pan is in a poor location. On mine we tapped the actual block of the motor where the oil drains through back into the pan. This was a reccomendation from Terry because he said this would facilitate good oil flow from the SC unit, because otherwise tapping into the pan 'could' in some instances reduce or stop oil flow from the SC since it was a gravity drain. One would think that the oil pump would keep things flowing but the small vortech line restricts it enough that it is possible for oil to slow significantly. This combined with the Vortech failure to include the oil loop in the intructions is a good explaination of why seals went out in the beginning.
Also on another note Terry said that he could investegate the seals in the SC and maybe source some higher grade ones to replace with. Might be another option for you.
How do you find out about the seals? Are you regularily pulling off the intake tubes to look for oil?
