Dipstick tube oil leak 96 7.3

obsonbogs · Sep 7, 2016

So after re sealing my motor and putting it back in , I got it running and driving again , but have an oil leak from what looks like around the threads of the bolt that goes into the side of the pan for the dip stick tube , is there a trick to fixing it ? It's not too bad but is almost a steady drip when running so I wanna get that fixed. Any tips would be helpful, thanks !

There is a nut on the inside of the oil pan holding the tube on that comes loose and allows it to leak. Aside from pulling the motor, the Strictly kit seems to be the favorite for those fixing it in-truck, though there are a couple other options that others have done.

Whs above, or you can put a new oring. It's a butt puckering job trying to not drop the inside nut. You have to run a pipe cleaner, coat hanger through the dipstick hole into the pan to keep the inner nut from falling, it's not fun but can be done.

Just did one of these jobs last week. Remove the starter. Drain the oil. Remove the dipstick tube. Get something like this that you have to forcefully push into the hole for the dipstick tube

Then remove the nut on the outside of the pan being careful not to let go of the pipe cleaner when you get the nut off. Take note of the way the hole in the adapter is facing because there are two positions it can rotate to. Fish out the old o ring and insert the new one. Make absolutely certain that the new o ring is in the groove on the interior adapter otherwise you'll have a leak. Put the exterior nut back on and get it tight. Nothing stupid but tight. I like to then smear some silicone around the threads to keep the nut from someday backing off. Reinstall dipstick tube and starter. Fill oil.

No, and it's super simple to install. I love it, I've used it twice.

But it can still leak, and now you have a mess you have to clean up to re fix it.

But does the nut on the inside of the pan fall in when you take off the outside to put on the new strictly one ?

Yup, that's not an issue. Only time it's an issue is if your truck is upside down. At that point, you have bigger issues.

From now on remember a big lesson. If you have an oil pan out, just go ahead and do a dipstick repair while there. Saves headaches.

Sorta like touching a SBC oil pump. If I can touch it, I replace it.
