    • Great price Nice product see review for info!
So I bought a 06 330I with all kinds of issues and I had no prior BMW experience. Fighting CEL codes and idle issues I've replaced a lot of parts. I did a smoke test and found the CCV system had broken lines. The kit that would fit my car perfectly was like $400 so I ordered this kit knowing that I would not be using the "Y" hose. Luckily the one on my car was the only hose not broken. My car was built in August of 05. Everything in this kit fit perfect except the hose that goes into the oil pan had 2 O-rings on it and I tried everything to get the hose on. Removed one O-ring still no luck. Removed both and it popped right on. No CEL lights so I assume there's no vacuum leak there. What did happen was since the CCV was bad for so long it has been dumping oil into the convetors and then the car threw the codes for the rear O2 sensors saying cats are bad. I added the O2 extensions and that fixed my issue. I did destroy the 1-3 cyl O2 trying to get it out. FYI spray with penetrating oil for a few days then use a small adjustable wrench and a 5lb hammer! None of the fancy O2 tools would work. Or tune out the sensors. But yes great CCV KIT! ... show more

The media could not be loaded. I broke both PCV hoses taking the intake manifold apart on my 2006 E90 325i N52B25 euro spec, to retrieve a broken disa flap out of number 3 intake port. After reasemble the car was running like garbage (it ran like the engine was blown) and disconnecting the MAF sensor helped, but it was still pretty rough. After swapping the whole PCV system, car now runs great and the engine has vacuum again. The only downside of this kit, is that the gasket on the lower PCV hose for the crankcase side will not work even after oiling it (too thick) so I had to remove the gasket and install a new one. Every other connection point (Lower hose to pcv valve, pcv valve to upper hose and upper hose to cam cover) works perfectly and seals great. Recommended if you are down to swap the gasket on the lower PCV hose and have enough patience to go through the installation of the kit (which is a nightmare if you cannot lift the car in the air) ... show more

The kit I received was close to the original. I did need to replace o rings on the hoses or at least the crankcase and valve cover hoses. I also had a clip break on the crankcase hose so I went to BMW for a replacement. The BMW hose fit much nicer and the hose fitting functioned must better with the proper o rings. You are always better off going with the OEM for replacement parts. I knew that but for the money this kit is not a bad deal. To put it into perspective the one BMW hose I purchased was almost as much as the whole kit. Everything else on the kit works ok. If your going to use this kit make sure you get the proper o rings. ... show more

    • Correct fit
Installed last week. I have only put a few hundred miles on the vehicle but at this point it is running correctly. CEL is off and the oil leak the separator was blowing through the breather system seems to be fixed. Originally the code I was getting was a MAF code, Bought a different MAF and the car actually ran worse. Ran a smoke test to determine the line on the far side of the motor to the separator was not only broken but also spitting oil that should not have been in the line. Indicating a bad separator and Hose. This kit is a good fit and seems to be exactly like OE, I would recommend the whole kit if you are replacing one line or the separator because once I got the manifold off I determined that all of these lines were broken, either in the removal of the manifold as they are extremely brittle or they were just cracked to begin with. Anyway if you are getting a MAf code or multiple codes indicating a MAF you might want to check these lines first. ... show more
