Some recent spirited driving (demonstrating the Vortech to a fellow poster) oil sprayed onto the hood underbody on driver side aft of the blower..Seems to have come out under pressure and the only oil line under pressure is the oil feed line to the blower..I called Vortech and they say they have not experienced this before. The car is at the shop and so far the feed line looks fine. Troubleshooting continues but anyone have any suggestions.The only blower seal to the outside world is the jackshaft seal and it's supposedly not under high pressure..Thanks

 

The jackshaft has nothing to do with oil. Could be your seal on the blower, could be the return line, could be a loose connection.

 

Say more about the seal on the blower. Vortech says only external leak can come from the jackshaft pulley seal..And if it leaked it is not under pressur.

 

Make sure your oil line isn't kinked anywhere and the connection to the supercharger is tight. I've had an issue with oil coming out from the oil line only at full boost though. Fortunately it was from the oil line and not the supercharger itself.

 

Was it coming out the line or at the connection to the blower?

 

No idea since I really don't trust anything Vortech has to say. My customer experience with them has been anything but good.

Just check the fittings and lines. I'd bet that your issue is there.

 

Check your dipstick too. If it is not in all of the way, oil will squirt out of the tube (yeah I know that doesn't sound right ). During tuning on my G, some oil squirted out because the dipstick wasn't all the way in and sealed.

 

check your dip stick........... I hade an oil leak vary similar to yours then I was like WTF my seal must be leaking. then I found out it was my dip stick I was lol then happy again.

 

Well no such luck with my leak. Mechanic says its coming out the blower..How do you run without the blower?? Coming out the input shaft...

 

I can't say for sure on mine but I would assume it to be kind of the same thing. The oil coming out of the supercharger couldn't flow into the line to the oil pan fast enough so it was probably coming out of the hose. I had a slight kink in mine so it only did this when I starting boosting to 9psi. I guess the line couldn't handle the volume at boost.

 

Were you boosting when it happened ? I had the same thing happen once . I could never figure it out . Oil was all over every thing on the drivers side . The only thing I could figure out as to were the oil came from , was the dip stick hole .
The oil feed line to the blower was ok , along with ever other thing I checked . The dip stick is the only place I could think of . It never happened again.

I would check the oil feed line out , but it sounds like you had the same thing happen

 

This happened to me to. The return line that Vortech sends is crap IMO, plus it was a little short, I pulled it a little to hard to get it to fit and it had a slight kink in it. I replaced my return line with a better hose and completly rerouted it. I've not had any more problem.

 

Mechanic says it coming out the input shaft. This is the shaft that the toothed pulley (last pulley drive) is on..Gotta go back to Vortec for disassembly and repair.. Anyone had this problem??

 

thats odd , and hard to believe . Is it still coming out of the blower ? Or was it a one time thing and has never happened again ?

 

Always leaking...Even non boost/idle..per my mechanic. I have not yet personally seen this..

 

Well if the Mech. says its leaking all the time....thats a first for me to hear about such a thing . Call Vortech and send it in . I dont think the cog belt running to the back side of the pulley shouldnt be hurting it . Unless you were running the belt super tight .

 

Not super tight can get it to rotate with fingers and lots of tq..

 

Seems Vortech has a problem with thier seals . I have had 2 blowers with seals that went bad . Not the one you had go , but non the less a seal .
Call them first , they will give you a number to put on the shipping box and to see if it covered under warranty . Good Luck !

 

Update on the problem..The blower was shipped to Vortech and they determined all the bearings and seals will be replaced. I asked if they run some sort of dynamic test to verify the blower will be good to go and the response was "we have no way of doing such a test".

I find it mind boggling that Vortech a major mfg'r of superchargers has no in house capability to verify a repair has been successful. He did say they do a "quality check" of the repair.. I asked "how can you do a quality check after the blower is buttoned up"?. He didn't know.The good news is that the repair is covered under there warranty..Keeping fingers crossed..

 

Well IMPO I think they do have some sort of test machine they could check it on . How would they do R&D on new project blowers if they didnt ? I think they just take the blower apart , change the seals , and check clearances and bearings and call it a day . If that checks out , there isnt any reason the blower wouldnt work . Unless the man doing the job F-cked up
