Ok on my cosmo 13b, I got a factory oil sending unit for it. I got this damn thing in there about as tight as it will go and its leaking oil, anyone got any ideas? I clean it up really good and start the motor up about 10 seconds later, here comes a little oil dripping down I have tried teflon tape, all kinds of things.

Im positive its coming from around the oil sending unit, I can watch it come out of there or close to... I have got this thing in there so tight Im afraid its gonna snap off if I turn on it anymore Anyone had this problem?

 

Are you referring to the "Golden Mushroom" under the Oil Filter? On the rear end plate?

 

usually a little silicon or teflon tape will work...

Yes that the one..

@j9fd3s I tried teflon tape... God I hope the back plate isnt cracked on this thing, I will so severly PISSED.

 

i used an o ring on mine and that worked the best someties the threads are just a little to big and an o ring will work. Try that it might help.

I just dont see how an O ring is gonna do it on this one

I might try some liquid teflon... See what that does...

 

are you using the tefolon tape in a blue/white container? i would try some gas pipe tape, usally in a yellow/black container. its thicker and imo better for automotive applications..

 

you need a small one that fits between the threads and where fitting ends it has to be a tight fit around the threads.

I got a crapload of O rings in about anysize you can imagine... I just dont see that making a seal againstthe housings flat surface and the oil sender's bevel surface after the threads.

 

that is simply what i did and it stopped mine. my dad had the idea we tried it and it worked. i was just offering advice on what worked with us.

I think Im gonna use a whole tube of loctite 545, thread it in there with an o ring as tight as I can and then TIG it to the block LOL

No seriously I think setzep has me set straight...

 

you have a tig welder. i envy you.

jr

 

yeah, just had to smack him around a little

 

Well then. How about posting the answer for everyone to benefit?

 

Gonna use loctite 545 and cross fingers...

 

Now that's scientific.... I'm glad surgeon's don't use this method..... errr ...... on second thought, maybe they do.

 

Just use some jb weld on it, and hope you never have to take it off.... or not.

 

Yeah man I hate having to reclean a surface that has oil all over it , just to have to take it back out, I think I had this thing in and out about 10 times. Im just hoping the damn rear housing thing isnt cracked...

 

so? Is it holding or what? Don't just leave us hang'n like this.

 

I like the JB weld idea if it's still not working. That stuff is great. And if you ever did need to take it out, it can be broken with a little finesse (read: force).

 

I posted a thread the other day that said Yeah no more damn leaks or somehting like that...
