little leak behind lower pulley after installing serpentine....

[800screws]

I just installed a serpentine belt kit....actually did it a week ago, but took it out for a test ride today....I have a little oil leak behind the pulley now, it was dry when it sat this past week...
it had a sand seal with the old pulley....did I unleash a can of worms by removing the sand seal? and was I supposed to installed another seal when I installed the lower serpentine pulley?
any thoughts or ideas?

Sand seal cut case needs a sand seal pulley.

Wow. That puts a damper on things

[cbeck]

But was the case cut larger for the sand seal, or was it a small adapter glued in to hold a seal? My last two engines had the latter. Then there is the spiral fluted vs smoothed od on the pulley snout going into the case. Pics?

[800screws]

I'll get some pics. But what I took out was this seal and piece of aluminum. It was pressed directly into the case. It didn't have that bolt on holder....does that mean it's machined, or no? And should I get the bolt on holder? It was a pain to get the aluminum piece out

[Bama Dave]

I believe your only option is to put another proper sand seal (not bolt on) back in. Then you would need the proper sand seal pulley.

ok.........that's the plan im gonna go with. thanks

This is an adaptor sand seal made to be installled in a Non-Machined case.. The pully was also machined to accept the sand seal. If you pulled this out then your case Has Not been machined for a direct installed sand seal which is why they used an adaptor. All you have to do is put in a stock style new pulley with the grooves cut into it and you will have solved the issue Because the case was not cut and an adaptor was used. If you look at the pully you pulled out the seal area would have been machined smooth with no spiral grooves cut into it like a stock pulley. Just get a new pulley and it will work because the case is still stock un-machined. Or....you can buy a new seal install it back in the aluminum adaptor use sealant on the adaptor part and install it back in the case, then use the pulley you took out. BUT you better look at that pulley as more than likely it has a groove cut into it from the old seal as a lot of the cheaper ones get damaged. In your case if you don't care about using a sand seal just put a new stock pully back in not using the adaptor it will be fine.

This is what I remember the machined-in seal to look like:

The image you posted above would be the bolt-in if I'm not mistaken.

Also might want to note that the bolt-in setup uses a longer-than-standard bolt (and if reused would not necessarily secure a stock or similar width pulley and seal into place).

[oldschool5er]

Third is correct the pulley bolt is longer. So if you go back stock you will need a stock lenght bolt.

if its not machined.......then why the heck did the serpentine pulley weep oil! are u supposed to put sealant when installing it?

do u use the spacer that u put in first with the sand seal kit, with the serpentine pulley? I took it out when I put the serpentine pulley on.......

oh man.....so confused! lol......

id just use the serpentine kit if I knew how to stop the weeping......




I planned on just reinstalling a new bolt in sand seal......but id rather use the kit I just got if I could stop the oil

[Third]

Well, you can often just look a VW like a Harley.

It'll stop leaking eventually (when the oil runs out).

[800screws]

Well. I'm giving it another shot. I heated up the pulley and greased the crank. Gonna see if that helps. If not. I'll just go back to the sand seals

[cbeck]

Is the new pulley smooth or spiral grooved on the outside of the snout?

[Vanapplebomb]

I never understood this, so maybe someone here can help me out. What is the point of the serpentine belt conversion? I have never seen a fault with the stock v-belt... It's not like you need the extra grip to run 30hp worth of accessories...and nothing requiring a belt that can be doubled back on a tight radious over itself and around idler pulleys, etc... so, why?



Just curios.
