Welcome. This is by far the friendliest forum I have been on. The 617 engine works very well for vacuum oil change. Even the filter change can be done without spilling a drop.

If you do not know the service history on yours, adjust valves soon. It is a DIY project and well worth it.

Go to FastLane for most parts.
