Replacing The PCV System On A BMW V8 Engine Part 1 Of 2




What do you think about this video?

Gerry Gorman: Hi, would you think it would be prudent for me to change the check valve on my M62 V8 engine, there is no sign that the part is failing but my car has covered 125k miles now and I'm looking at replacing various parts such as the check valve, water pump etc. Thanks Gerry

Gerry Gorman: Hi, I have purchased the check valve today from BMW for my 4.4 V8, I have noticed that my check valve is slightly different to the one you installed on the 7 series V8, the bottom pipe on your check valve has a right bend facing towards the front of the engine, the one that I have bought from BMW is facing upwards, do the valves change slightly in shape to suit year of car etc, I have crossed checked the part number with realoem and it is the same as the BMW part. Thanks Gerry

john vorobyev: Ill try the little vice grips just incase that doesn't work how would you suggest to break it off ! Now if I do break it off will it ruin the housing for where the bolts sit in?

calvin haugabrooks: I have a 95 740i ND I noticed the pcv valve dosnt have a center nipple and the manifold dosnt have a pipe going through the middle

john vorobyev: Well I tried the needle nose plier! Not enough room! So I'm going with taking off the intake manifold now ... Any advice on that anyone? 

john vorobyev: hello . i have a problem that i need help with . i have the same bmw but 540i tring to replace the pcv as well but the bottom right 3 torx bolts are stripped what would be the best thing for me to do at this point?

roon demahom: Excellent presentation. Explanation very short, sharp & straight to the point. Very easy to understood theory & practical. I liked your way of tutorial, slow & calm. Double thumbs up to you & once again a big thank you for your very useful info & tips. You are one of Professor Genius Sir David Einstein of modern advanced mechanical engineering. (:-)

Ebida3: Just replace the membrane. Pop the OSV cap off and replace, done. 10 min job, no busted knuckles or frustration. The plastic housing has no moving parts and never goes bad.

YANKH8R: Great video, thank you.I did as you said with the gasket replacement but the service engine light is still coming on.Quick question, the tube you refer to inside the manifold, I didn't feel one after carefully taking off the plate.All I felt was a hole where the nipple, presumably, butted up against. Am I supposed to be able to actually feel this tube? If so, why can't I...could it be disconnected inside the manifold? The BMW dealer said the smoke (test) was pouring out through the plate...?

immrtl d: Would the pcv prevent car from starting after long term parking of a year or maybe a dirty maf?

Shannon Howell: Hello im curious if this part could be my problem with my 740 il as well. My car runs very rough and seems to be blowing blue smoke, i know its burning up the oil and seems to be going through fuel as well faster. It will cut off some times when i stop amd has trouble taking off seems bogged down if you will.. would this part being faulty cause these problems. I work on mu own vehicles bc i cant afford to send the bmw to a shop with their high costs. This one seems like a simple enough fix. Shan

BavarianAuto: In order to help you out, we really need more detailed descriptions of all of the symptoms and problems ... and exactly how and when they are happening. Additionally, have you done any work or diagnostics toward solving this issue? Have you used a tool to check for any stored engine fault codes? For further assistance, please email to us at info@bavauto.com .

BavarianAuto: Yes, the check valve assembly certainly could be at fault. We would also check the condition of the spark plugs if it has been using the oil for a while. Additionally, you should clean the MAF with our Mass Airflow Sensor cleaner. You can see it at bavauto.com ... part number 05110

BavarianAuto: The PCV system should not cause a not-start, with the following notes: If there is a major vacuum leak due to one of the PCV hoses being cracked and open, this could cause difficult starting. If the PCV oil separator is clogged, this can cause major amounts of oil to be sucked into the intake and the cylinders, causing a hydraulic lock. In this case the engine would not crank (or turn over).

paulcomi: The hardest torx bolt to remove is the one on the bottom toward the center UNLESS you change your tool set up. I found that a Makita 1/4" extension (used with cordless screwdrivers) fit perfect. I used the same ratcheting wrench on the extension and had a solid bite on the bolt. I was able to remove the PCV in about 45 mins. Now I'm preparing to put the new one in!

BavarianAuto: Yes, the tube can indeed become disconnected from the forward manifold cover (throttle body mount plate). If you remove the front cover and throttle body, you can check this .... and it's much easier to do. You will need a new gasket for the cover and for the throttle body. We have these in-stock at bavauto.com or call at 800-535-2002.

Ramb Puk: hello. iv got bmw e34 540 93 year. and i have some strange things going :( whens i leave it for week and then start it up i works well untill warms up. then starts something strange.. it sounds like few cillinders not working.. what can it be ? diagnostics cant tell what is that. sorry for my bad english.

BavarianAuto: All parts needed to do the repair, are in the kit. You may, however, wish to order the short vent hose (# 11 61 1 440 126) as this may be brittle and crack or rip while being removed. This applies to the V8 M62 engines from 99-on (540i, 740i/iL, X5 4.4 & 4.6is through 03).

BavarianAuto: Good thoughts. Thank you for sharing. We have added a note about replacing the bolts, on our listings for the kits.

giantj6ft7: Could you tell me what the two upper hoses go to on that assy.? My 94 740il has these lines blocked off, not sure where they would go.

BavarianAuto: @paulcomi Good comments! Thank you.

Christine Gramada: thank you friend! u r so nice to provide this for us!
