MRZ pulley***look here if you have

[Jn2]

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

i was looking at getting there new lightweight alternator pulley for the lsj hmm

 

[Jn2]

well idk if its the pulley or the guy installed it wrong

 

[cobalt123]

i hope he just installed it wrong, the lightweight alternator pulley weights so much less

 

[Jn2]

I installed one on tylers 2.2 and it leaked all 5 quarts out,pulled off the MRZ checked the seal.seal looks brand new,put the stocker back on and perfect.no leak.looked at the shaft on the mrz and theres a fucking groove right where the seal sits.ive heard they "updated" this problem but im still sketchy.I WILL NOT be putting any of there produckts on my car

 

[Cobalt Tom]

very odd, i have had mine on for 6+mo now and no issues...

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

no, your alt would hate you cause of your subs, do stock size just lightweight

 

[YelloEye]

My alt hates me as it is lol, and in reality if I get a UDP isnt that going to make the alt spin faster (increasing power output and shortening its lifespan)? Or will it be the other way around and spin slower? I never was good at figuring out things like that.

 

[Jn2]

Nope, cars have voltage regulators, ur alt puts out gobs of power. Most put out enough to **** everything up. So spinning faster do much bc the regulator will still allow only the same amount of aperage...good for rev'n faster though

 

[YelloEye]

Right I get that part, and in thinking about it a little more, a UDP on the crank is going to make the alt spin slower by default. How many amps does the stock one put out? 140?

 

[Cobalt Tom]

even the mrz site says that if you run an aftermarket stereo system then do not get the udp

 

[YelloEye]

I musta missed that one lol

Where does it say that?
