Roketa mc-07-50t oil leak and variator wobble

Rampage401 · 07-22-2013, 10:20 PM

I have a roketa 07-50t limited I just got it used its got like 10,000 miles on it. My issue is there is oil in the side cover I noticed when I took it off to check the belt. Also the variator has wobble up and down and the nut is on tight. Please any help would be greatly appreciated.

Remove the variator. Your crankshaft seal is probably leaking. With the variator removed, pull on the crankshaft with your hand and determine if it moves in and out. It should move no more than .005", if it does, you have internal engine damage. (bearings, block, connecting rod)

Any of our sponsors have the 139qmb engine seal kit for usually around 20 bucks. It includes all the seals. But if a seal is not leaking, don't go replacing it, wait until a leak develops.
