914World.com _ 914World Garage _ Dip Stick seal

Posted by: malcolm2 Aug 7 2018, 07:57 AM

L-jet FI system so I am always monitoring vacuum leaks. I checked my oil the other day and notice a Ho-Made seal at the top of the dip stick. You know down (or UP) inside the little "hat" just below the finger loop. Looks like the PO added a few o-rings. And they are now stretched, twisted and sliding off.

I suppose the reading on the stick could have been off by a smidge all these years too...

Is there a better repair?

I found a post on Itinerant about leaking or blowing oil thru the dip stick tube. This shows a 6mm oring and then a 5mm oring. They say it sealed the tube great. kinda confirms my oil measurement theory.

I can look at making a correct one, I did notice that I had oil oil leaking out at high RPM (wind-age seal issue?). Just checked my seal used for the taco plate, it works ok.

I did plan to checkout your site. Maybe just need to add some marks on the stick

So no one has had to replace the dip stick seal?
