Probably not worth the trouble to modify....but I did the grommet/o-ring replacement two years ago...the job went fairly smoothly....then just recently the thing started leaking like crazy, so I had to do it again. This time, what a royal PIA!!! That damn lower grommet would not give, and I could not get the lower tube out....I had to remove the oil pan, and I couldn't even bang out the tube with a drift from underneath (the car was on jack stands and I couldn't get a real full swing with the hammer, but c'mon!!)...so I had to blast it with a propane torch to fry the grommet...finally it gave in.
Then, clearance between the top tube and bottom tube was very minimal, and I needed to flare out the end of the top tube to give a little more clearance to fit over the installed lower tube.
This whole routine is such B.S., and the set up is so poorly designed....all this thing does is drain a little oil into the oil pan, under no pressure...give me a break!
I don't like that the lower grommet hardens so fast (couple of years?). I suppose I could just replace the o-ring between bottom and top tube, but once I take the top tube out, it seems crazy not to replace all seals. Once more, a real PIA!!!!
Other than that, I have no strong feelings about it!
