It is rare -- make that impossible -- that all old oil can be drained from an engine or in this case a piece of machinery like a supercharger.Has anybody change the oil in their Whipple supercharger yet ?
Trying to do that and their doesn't seem to be a way to get all of the old oil out .
Does Whipple specifically require all the old oil be removed? If the setup is such that only half the oil gets drained -- if I wanted to remove all the oil I'd look at some siphon setup -- I'm pretty sure Whipple would take that into account when specifying the frequency of the oil change.One of the first things that I did was contact Whipple. What they told me to do did not work.I could only remove half the oil that was put in to the blower originally. So I decided to post here and see if I could find somebody that actually did it successfully. I also joined a Facebook group called Hemi Whipple owners. It has over 2,000 members But I couldn't find anybody who had changed the oil successful either.
Reads like a subpar design that relies upon a sight glass for oil level checking but in normal operation the sight glass gets so discolored as to render it useless for its purpose.Okay this is kind of a long story but here goes there's a sight glass on the side of the supercharger that's how you check your oil level. After 10,000 miles from installation the sight glass was completely black and I couldn't see any oil so I siphoned out oil from the top filler plug and less than half the amount of oil that was originally put in came out. Then I unscrewed the sight glass at the bottom and no oil came out I could see this sight glass was black and I cleaned it and I put it back in then I put the oil that I removed back in and the level was appropriate. When I contacted Whipple about it they said oh yeah if you siphon out you have to go more to the driver side of the blower with the siphon tube because the reservoir is deeper there. So I tried to do that every witch way and could only get another ounce of oil out. Needless to say the oil was very dark which after searching turns out not unusual. So if it's common for the oil to be so dark and completely black out the sight glass how am I supposed to know what the oil level is? I know I could ask Whipple that but I'm tired of dealing with them. I'm sure it's going to be fine and when the glass gets too dark to read the oil level I'll go through the same procedure again.
Thanks for your thoughts.
