recently i was asked if i ever had any issue with my crank pulley, iwas the first one to install it, based on what my exp, i didnt find anything out of the ordinary...but like i said i only had it on for a certain amount of time, which was up to the point where i installed my sc....

if you have one, could u please check the following:

-check for a oil leak
-focus on the are around the crank pulley
-check for puddling of oil on or around the cradle and oil pan


i have noticed i had some oil on the oil pan that i could never identify, i knew it was oil, but never found out were it was from, it was a small amount, enough to soak the oil pan as it dripped down, i have contacted other members that have one...so i will hear back from them


the long term effects of a mrz pulley are still unknown, please continue to install these at your own risk, im waiting for a response from another member that has one to see what he has to say, i know my oil thing didnt start to happend till i remove a gallery port, so it could be thats where the oil was coming from bc i didnt really put teflon back on it :p

Looking at getting the MRZ set, not sure if I should get the UDP crank or not though. Opinions?
