Has anyone else had the problem that the crank seal cuts grooves in the AEM (?? brain fart) pulley snout and then begins to leak? Happened on my VE. Replaced the seal twice... once when the pulley went on, and once after... set at a slightly different depth in the hole. Now has two grooves. Is this normal?? Seemed it happened pretty quickly... 20K maybe??

Anyone had to deal with AEM?

 

AEM? you mean ASP?
ASP will sleeve your pulley if you send it to them. the aluminum used is a bit to soft and the seal ends up cutting it as you found out.

 

I wonder if any VG owners have run into this problem with the UDP from UR. I have somewhere around 35K on mine...so far, so good...

 

ANY pulley that's aluminum and has no steel sleeve will eventually run into this.

 

Yes... ASP. Told you I was farting.

Sleeve it... good idea! Do they charge or are they doing a "good faith" thing?

BTW- I mic'd the thing out a few years back and it also wasn't the same OD as the stock pulley... was a bit larger- mine anyways.

 

the concept of a UDP is for it to be smaller than the stock pulley... this is what you notice in your UDP correct? if it's the same size then it's either stock-replacement, or stock-size but weight-reduced.

 

The snout of the pulley... you know- crank seal, grooves- post topic.

 

aww man .... not good to hear. I was planning on getting the ASP pulley too. Anyone know if they come sleaved already ???

 

I know. I was happy with mine otherwise. Probably had 50-75K on it. It's not the magic bullet, but evey little but helps.

 

just replace the seat and tap seal a little farther into the front cover or not as far as before so it rides on a different spot on the snout of the crank pulley. this will just let it wear another groove over time. but should fix your leak.

 

With two grooves already, I'm running out of room to "groove".

What are you saying exactly? That I should try to have three or four different grooves on the pulley? That I should fix a leak every 10-20k that otherwise wouldn't leak for 125K. I'm always on a "no leak mission".

I prefer when my 244K VE is running synthetic oil and has used less than a half quart at 7K instead of dripping on the ground, coating the underside of the car and wiping out the bushings that I got greasy from having to replace because i had leaks.

 

not that I have a udp but do you have any pics of these grooves you guys are talking about? i'm still having a hard time wrapping my head around what the actual problem is that you're experiencing..

 

Not sure what's hard to understand. Pulley rides against seal. Seal wears a groove into the pulley making the clearances bigger. Bigger clearances cause oil to leak. Result is a mess of oil leaking at the front of the engine.

Solution if you have an ASP pulley. Send it back to get a STEEL sleeve installed. Problem solved.

 

i never got a good look at that stuff back during the tbelt job, because that was back before i had the ***** to do everything on my car so my uncle did the actual work. so i don't know exactly what everything looks like, and how it goes together, and how big the seal is, and all that stuff.

 

Jeff: Speaking clearly as always.

The question I asked earlier in the thread was if ASP charges for the sleeve or if they do it for good faith/relations. If they charge, how much... if any one knows?

 

I believe it's free if you don't have the sleeve. Could aways call. That's what I did
