A PCV (positive crankcase ventilation) breather system is been designed to regulate hazardous waste from your vehicle. As your engine runs, combustion gases escape from the combustion chamber, finding their way into the crankcase of your engine. This unused combustion gas, also referred to as “blow-by,” can be a major cause of smog. A PCV system prevents pollutants from escaping into the environment and vehicle manufacturers started fitting engines with a PCV valve to ensure that gas remains contained within your vehicle.

What were the symptoms that you had a clogged up PCV?

kerry krishna says:

Will this be the same for my 04 XC70 ? Thanks so much!

Rick J says:

I really wish you hadn't taken a short cut and instead replace the entire hose where you cut out a section because you found the part available. For those of us that don't have that option I'd like to have seen how you attached the other end of the pipe going around the block to the turbo.

Terry Hesticles says:

Curious why he removed the fuel rail assembly from the intake plenum. On my S40, I was able to leave them intact.

Scott Muas says:

Does the breather affect the turbo boost? I seem to have weak around that area but I can't tell exactly where it's at. But it sounds like it's coming from underneath the intake manifold

Anthony Rivera says:

Does anybody know how to get the air out of my cooling system on my 2004 Volvo S60

Mi Li says:

How much do you charge for this job? Mobile mechanic? What's average repair shop cost to do this? I'm getting too old to work on cars.

SECDEFF 66 says:

Nice video buddy…question on the crimping tool you have. I can’t find one that is straight and can do straight on plus offset like yours. Please can you tell me where to purchase one! I will be doing this job within 2 weeks.

Mike Patterson says:

It appears that you're using a 3M Roloc disc (80 grit?) to clean the intake. There are some that say using the disc may damage the surface. You're opinion/experience with these discs?

jon mccall says:

how much difference is there between the p2 nd p3 models will this video be close to the p3 installation?

s60polestar fan says:

Love your videos. Very informative. I replaced the whole pcv kit with the big hose on our s60r.

andy skinner says:

another brill step by step video jay ,you always make these look easy but at least you do give note at end that it is a bigger job.great videos .

Lou Larson says:

Can you give me a part name/number for the "Cookie Wheel" you use to clean intake? Thanks.

Jay Obrine says:

Thanks so much for the Video! Can part #30731007 be cleaned some-how on or off the vehicle? Maybe soaking it in solvent or a degreaser and using a thin wire and air pressure through the hose to clear it?

Kalle Hjelmström says:

Thanks for the video. I would really like to see a diy video about how to replace Clutch on a Volvo S60 2000-2008. That would be great!

Frank Strassler says:

I'm working on my 2006 XC70. I cannot get to the 10mm bolt at the bottom of the Oil Trap. Looks like I would have to remove the large alum bracket holding the power steering, alternator and ac. Any advice?

Mikele Schnitman says:

Ok, made a little install slideshow from youtube. Thank you FCP EURO!

But XC70 2004 has a few extra steps, can anyone help with those?

Mikele Schnitman says:

What 'Silicone Grease' to use ?
any materials+tools list that I can use for purchasing prepping for the job?
