Been an owner of a cmep-ol for two years, never used it on an extraction though as it was depositing bearing grease into my butane stream since day 1. Finally got it rebuilt by bhogart and was told it should all be completely cleaned out and in working order. Turned it on just for a second and noticed a smell coming out of it. I was instructed to run a little clean solvent through it, which didnt help at all. So I decided to tear the thing back down. Discovered that all the piping inside the machine contains black deposit on the inside which can only be wiped out and will not rinse out. The smell is within the whole entire system as well. Got to noticing that one of the piston seals is slightly worn and has a knick in it while the other is perfect, other than being greyish from wear already from a minute of being on. which is very sad if they are new seals. Which is odd as this was the original issue. The first time I took it apart before I had it rebuilt there was a damaged piston seal, which had me believing that an excess of butane was getting into the crankcase. Back to now though, all i have done is run a little solvent through the machine and the crankcase is dirty. There is a small amount of black grease all around the crankcase, mostly on the bottom, and also the back bearing looks to have grease coming out of the seal on it, but the front one is 100% dry. To me this machine is either a lost cause, or bhogart did a sub-par job on it. Either that or nobody out there is actually running one without contamination. Nearly $5k into the pump now and ice/butane wasted on it. I need some serious help with this thing if anyone knows anything thay may help. Going to be calling bhogart more today. Yesterday two different people there told me they would call me back and nothing. Thank you all.
Also going to note there was some splatter around the crankcase, showing that its coming right off the back bearing most likely, since the front one is clean. Also, the bearings are 6908DU. No longer "RS".
