Well done dipstick tube O ring replacement by MVS Volvo Forums superstar Jreed!

During a routine oil change last week I noticed a little oil seeping out around the base of the dipstick tube where it enters the oil pan. I ordered a new seal ring from IPD (using the ad link above — great prices these days at IPD!) and installed it this morning. There were several write-ups already on the site about part numbers but none that I could find that showed the procedure…

Step 1: Identifying the source of the leak at the base of the dipstick tube.

Step 2: This swivel head stubby 1/4″ drive ratchet proved to be very useful to get at the bolt holding the dipstick tube in place. Use a 12mm socket for the bolt.

Step 3: Loosen the 12mm bolt — fairly awkward access. To break torque on the bolt I had to use a longer handled swivel head 1/4″ ratchet.

Step 4: Clip off the tie wrap (if you have one installed between the power steering line and the top of the dipstick tube) and remove the dipstick tube from the oil pan by pulling upward.

Step 5: View of sealing surface. I wiped this a little bit with a wet rag to clean it up.

Step 6: Cleaning up tube and inspecting old seal ring. The old ring was still pliable — no cracks, swelling or shrinking visible.

After removing the old ring and cleaning the end of the tube thoroughly, I put on a new ring and then reinstalled the tube in the oil pan, put the bolt back in (medium tight), and installed a new tie wrap to hold the power steering line to the oil dipstick.

Not a bad job, just difficult to reach the bolt and sealing surface.
