The B58 has been known to be a very reliable motor compared to it's predecessors like the N54/N55, but it does have one common issue; PCV failure. Unfortunately this has become a very common issue, especially on cars with upgraded turbos running a lot of power. Luckily, it's a super easy and cheap fix! This kit comes with everything you need to replace your broken PCV diaphragm without having to replace your entire valvecover.

PCV Failure Symptoms:

  • Misfires
  • Rough Idle
  • White Smoke Coming Out Exhaust
  • Excessive Blowby (Oil in intake, chargepipe, etc)

Fits all Gen 1 B58's! Does not fit B58TU (Gen 2)

OEM Valve Cover Part Number:
11127645173

Got the Job Done

Had a diaphragm failure but was prepared with a kit from MRM, got me back on the road in 5 minutes. Can't speak for longevity but it sure did save my butt!

Worst customer service ever

After receiving the products, My mechanic informed me that I already had the high-pressure fuel pump and did not need anything in this order. For Almost 2 weeks I have been trying to set up a return with your company by leaving numerous voice, messages and emails and have yet to receive any contact back from your company. I am still trying to set up a return with your company.
