Engine/Transmission (1994 - 1998) oil in vacuume line/sctuator

[rstorrey]

i recently replaced the vacuume line to the cruise control actuator & noticed the old line had some oil dribble out of it. while trouble shooting the panel actuator for the bi level air outflow, a drop of oil (or so) also dripped out of the actuator. suspect there is a seal bad in the vacuume pump. is the seal in the pump replaceable or is it time to replace the pump? thanks for any advice.

Could be one of your check valves went bad.

Probably the absence of a check valve at the vacuum pump. Mine was repaired under recall.

oil in vacuume lines/actuator

Thanks for the replies to my post concerning oil in the vacuume lines. After reading the TSB, i think i know the problem. my truck idles ALOT, in the winter months. i cleaned almost all the vacuume lines and cruise control actuator/defroster actuator & the 4WD actuator, found a little oil (maybe a drop or so) in each. the check valve in the vacuume pump i removed & cleaned up. there was bit of oil in the pump housing (where the check valve screwed in) but no more than 2 pipe cleaners were able to clean up. the check valve ops ck'd good. in the future i will be more vigilent as to how long the truck idles. thanks again to all who replied. rs
