i’m currently changing my pcv. i can’t wait till y’all make a full on kit so i can just bolt on an go 🙌

[@BrianKariuki]

I love this. Our CREC engines are dying because of poor crankcase venting. The crankcase is only venting from one bank, instead of 2 banks like the earlier engines. I am looking to get this relocation kit and top cover for the second bank with an outlet for ventilation for bank 2. I am curious if the ECU will throw errors for pcv. We also have a n54 valve on our engines, so that might be a doozle. Kindly reach out so I see if we can work together on fixing the oil consumption issue on the CREC engine

[@swankperfection]

What’s the new crankcase vacuum measurement with this external PCV? B8 S4 ones are either 30 or 150 mbar depending on PCV revision and ECU updates. This is important info missing from this video.

[@swankperfection]

Also, FYI, on the new external PCV, you could use the OEM vent tube ends that clip in place on one side as that’s what it’s designed to take and on the other side, it would be nice if Merc would make a new aluminum female to barb hose adapter that accepts the the bottom port of the PCV to be inserted in at an angle. That port has a ring seal around it and also is keyed to go into a factory port like that. Would make for a super clean install and OEM finish without all the junky JB Weld DIY stuff and zero modification of the PCV should you ever want or need to swap that out entirely rather than just the guts. It’s definitely something to seriously consider to make the install clean as hell. 👍

[@AudiC7Owners]

Thank you! At present I am not as my guides are working great (knock on wood).

[@joanneanderson1583]

Excellent video as usual from you, only one thing that is confusing me! You have replaced the OEM plastic PCV with an aluminium one from an older model car and installed a separate relocated PCV, but you also put a PCV valve back into the new aluminium housing under the super charger. Why fit 2x PCV’s, and couldn’t this still go bad meaning you have to pull the super charger back out in the future?

[@AudiC7Owners]

The Metal Valley Pan under the supercharger is just that. There is no pcv in it. The plastic piece that is on it is an oil separator (think oem catch can). These rarely have any failures. The only pcv is the relocated one 🤘🏻 Thank you for the kind words!

[@emolutioning]

Yeah that was what i was thinking of too. Why not just remove n bypass the Stock Oil Separator and direct to a Catch can from the Crankcase Inlet/outpipe?

[@AudiC7Owners]

That would be impossible. You have to have the oem valley pan/oil separator in the engine for it to function correctly.

[@brian221969]

I love the content and direction here (fantastic videos), but I'm struggling with MercRacing at the moment, I ordered the kit on June 4th along with everything else on your list to relocate my PCV system and upgrade to the 3.2 manifold (also doing intercooler bricks while the supercharger is off), I have the catch can installed in my S4 and have located the spot for the diaphragm breather, and have it all ready with the connection JB Welded and black taped into place (the links were extremely helpful). I've watched all the videos, and ordered and received all the gaskets and O rings for everything, and feel fairly confident I can do this. I emailed Merc Racing asking for tracking info, as the order email still read "processing" and also the very first thing I ordered. The package came today (6/17), but is was missing the throttle body spacer gaskets and the longer bolts for use with the stock throttle body... so another contact email sent through their sight. I'm going to rewatch everything this week to make sure I have the process fresh in my head, hopefully I'll be able to start next weekend. I had hoped to have it complete by now.

[@brian221969]

Update - MercRacing shipped my missing parts today, so very responsive. Next weekend, tear down on my S4 begins!

I ordered the kit from Merc Racing a few weeks ago. Got an email back saying some of it is on backorder with no eta on those parts. Within a few days I received everything I ordered. Ordered a few other items from FCP Euro some off Amazon like injector seals, aluminum oil filter housing, oil filters, and I got an aluminum coolant (water) pipe with O rings. The one that comes out the back of the thermostat. Now I just have to put it all back together.

Hi Cameron, need some help please, looking to relocate PCV like you have done in this video…since making the video do you know if anyone has successfully done this on a 3.0t CREC motor. I have the 3.2t metal crankcase seperator and keen to utilise merc saving kit but really need to know if this will work.

Hello Please tell me where’s the fuel temperature sensor located on Audi a7 3.0 TFSI Best regards

[@trumpetize6230]

I do have a question. Why return the pcv to the intake instead of just venting to the side of the engine? Intake would love breathing cleaner

[@AudiC7Owners]

Because it is a pressurized system. Venting to atmosphere would cause it to operate poorly. Catch can cleans the return well though

[@drumhed]

I am going to be doing this on my D4 A8 L very soon!! I will happily share the details with you.

[@bobd9868]

Did you do it? I have a 2016 D4 as well

[@drumhed]

@bobd9868 Yes. Did it about 6 months ago & 5k miles. Significantly beefed up my plumbing approach compared to this, but I followed Jose and Cam's basic program with the Merc Racing parts. I also implemented a catch can.

[@joanneanderson1583]

Thank you for clearing that up for me Cameron. Just me not listening properly.

[@AudiC7Owners]

No worries!

[@crapmuhap]

The end that comes off the new spider hose will connect to the new pcv so you only need a 19mm 90 degree barb and some hose. The other side of the pcv is a 14mm hole so you can tap that and match that to the catch can.

[@shanemarston959]

[@zuperzleeper]

Ummmmm there's no pros on keeping the PCV, why no just route the hose from the spider hose to the ground? just dump the positive crank case pressure?

[@See7ayyeesix]

Can we just delete the PCV / vent to atmosphere…for off road use?

[@AudiC7Owners]

No. There is no block off plate that would allow this and the entire system is designed to stay under vacuum. No one has accomplished deleting the pcv on this system to my knowledge

[@See7ayyeesix]

@ stop me where I’m missing something….merc racing supercharger plug, vr6 valley pan, and breather filter for crankcase, toss out the rest of the PCV system?

[@AudiC7Owners]

It isn't a vr6. It's the Audi 3.2 which isn't a VR. Just don't want you to get the wrong part. Your entire oem pcv system is being replaced, yes. Basically converting it to the Audi 3.2 pcv system

[@dominickkrahnstoever7362]

I seem to have had a failure of some sort with the relocated PCV. I emptied my catch can today and found it full of the forbidden chocolate milk. I seem to be getting coolant and oil mixing in the system somewhere. Are there any culprits for mixing coolant and oil on the 3.0T besides the old PCV system? I find it unlikely that I have a head gasket failure but that's the only thing I can think of since I dont have the stock PCV system anymore.

[@AudiC7Owners]

There is nothing wrong. That is 100% normal to find in a catch can. It isn't coolant that mixed with oil, but rather just moisture created from the combustion process. Sounds like you're pcv and catch can are working perfectly

[@lukes317]

Quick question here. I’ve got a coolant leak I can’t narrow down quite yet. I pressured my coolant system to check for leaks and it dropped real quick but no visible signs of leaking. All my research so far leads me to believe it’s pooling under the supercharger where the coolant return pipe is. I’ve seen a lot of people saying to check there first but I’m apprehensive to take the supercharger off if there are some parts known to break. Any advice on what I should get before taking the supercharger off and anything else that would be a good idea to replace while under there? I have a soft code for PCV and I’m thinking breather hose and/or the diaphragm but I’m not sure how easy those are to replace while under there. Thanks in advance!

[@AudiC7Owners]

If you are pressurizing the system & song coolant without seeing anything leak then your pcv is likely cracked & you free mixing coolant into your engine oil. Drain your oil & check it. Having a pcv code means you're pcv diaphragm is shot anyways so you need to address all of this quickly

I’m throwing a PCV code on my 3.0 c7.5 Has if been tested for us yet? If so I’m ready

[@tb3780]

This kit does NOT work on a C7.5. We have dual port injection (as opposed to direct injection) and a very different PCV. You can use this video to help you DIY replace your PCV, as well as the one by FCPEuro, but don't buy these parts expecting to put a catch can on your C7.5 (or C8.5).

[@AudiC7Owners]

It actually does work, but you have to modify the plastic oil separator that attaches to the metal valley pan to fit correctly. We have had multiple CREC vehicles do the relocation.

[@blucobalt8688]

would this work an a c6/2011 a6 3.0t?

[@AudiC7Owners]

Yes

[@cheevue9320]

Thanks a lot! Now I just spent over $500 on this project 😢 I guess priority first

[@AudiC7Owners]

Lol good luck with the install! Lemme know if you have any questions

[@gaschris7989]

I wish I watched this video earlier. My coolant is mixing straight into the oil and I already put a 2k deposit on a new motor🤦🏽‍♂️ I’m definitely checking the pcv before I pull this motor out has 247k miles I put on but still runs strong.. other than fluid mixing.

[@AudiC7Owners]

That's impressive mileage!

[@See7ayyeesix]

Yeah this is awesome but the carving out and glue are non starters for me

[@AudiC7Owners]

There might be something to telegram that in the future but we aren't 100% yet. Its not hard to do though

[@Pollinator]

Great vid. Looking forward to doing mine in a few weeks. Just a thought … would it not be possible to get an AN10 fitting with a smaller thread diameter to save having to do all the filing in the PCV fitting ?

[@saulrivkin7323]

How much pressure is under the supercharger for the plug underneath? Could you use a rubber freeze plug (the type that tightens with an internal bolt)? How about a hard metal freeze plug inserted? Seems like any of these DIY options would eliminate the need for a special part only available at one or two places. Thoughts?

[@AudiC7Owners]

Just buy the mercracing plug. It's extremely affordable for piece of mind. I will never recommend a plumbing plug for something like this. If you choose to go that route, do so at your own risk

[@abhiT569]

anyone did it on the CREC ? i'm planning on doing it soon ! lmk if anyone has had success or hiccups !

[@AudiC7Owners]

Yes they have but they have to modify the plastic oil separator that attaches to the metal valley pan to fit. There is a post in the Facebook group about it

[@danaranwar4528]

i have audi a6 3.0t , It reduces the oil of the engine very much without my car having smoke or leaks, for example, it reduces 1 l of oil in 200 kilometers while I put a lot of pressure on my car What is the reason for this reduction? And what's the solution? I live in Kurdistan I can't reach good people in this field

[@AudiC7Owners]

Check out our oil consumption video. That covers the majority of oil consumption/leak issues.

Has anyone had luck ordering this kit lately, I ordered in December but have not received any confirmation. Getting no replies to emails either. Just waiting with my car in pieces right now.

[@AudiC7Owners]

The order in December was a pre-order. We were very clear about that. Mercracing is waiting for parts to arrive from factories.

[@benharbold7890]

@AudiC7Owners Sorry, didn't see on the merc site when I ordered. Just saw that orders would be processed in January. Still excited to get my car up and going again, thanks for the info.

[@A6.Andrew]

i want to buy this kit so badly but i dont know anyone to help me with this. I am too scared of breaking or fucking things up and my car has been sitting.:(

[@AudiC7Owners]

Where are you located?

[@A6.Andrew]

@@AudiC7Owners Midwest in wisconsin. We don’t have very many Audi mechanics at least right where I’m located and it’s been incredibly stressful the last 2 weeks w/o a car.

[@AudiC7Owners]

There are a ton of video references to be able to do it yourself. Try to find a local audi club near you

[@A6.Andrew]

@@AudiC7Owners haha I’ve watched most of the series. My issue is having tools and the knowledge of this specific car as a whole. Not sure if it’s able to be ran in it’s current state if it’s going to end up damaging it vastly more or not. Will definitely look into some clubs or something around me. I appreciate it 🥺♥️

[@mk_ultrarunner]

Why couldn't Audi do this? Oh wait... then the Audi dealers couldn't charge $2,500 to do a PCV replacement AND a bunch of extras. Also you said the whistle is normal on the diaphragm, but isn't that one of the symptoms of a bad diaphragm? I had a whistle on mine, but not high pitched like the videos I've seen, but more noticeable on defrost. I was hoping it was not something in the vents b/c not much I can do to fix that. Will see is the PCV body replacement fixed it or will it be a "phantom" whistle I have to deal with for the life of the car. That will be frustrating if so.

[@AudiC7Owners]

Turns out that sound was bc my diaphragm in the housing wasn't perfectly seated. I reset it & it went away.

[@sebastianzink84]

I would buy a bolt on 👍 KR from Germany ☺️

[@svetlinpetrov-wb1rz]

Could you please elaborate a bit more, from where in Germany you buy it bolt on?

[@boogeymana6]

Wats up nerdssss

[@tb3780]

Don't make my mistake... I bought all these parts and took apart my 2016 A7, only to realize this kit only applies to C7 not C7.5. Our facelifted models use dual port injection and are not compatible with this earlier vintage valley pan conversion. Wasted a lot of time. Made the best of it by replacing PCV, water pump and thermo, while I was in there.

[@AudiC7Owners]

1) this is the first line of the description of the relocation parts kit on Mercracing's website: "**CREC & C6 A6 ENGINE COMPATIBILITY UNKNOWN**" 2) having pointed that out, we have had Multiple people with the crec engine complete the relocation. You have to modify the plastic oil separator that attaches to the metal valley pan to fit. There is an entire post about this on the relocation Facebook group for anyone interested.

[@tb3780]

@@AudiC7Owners that's fair. Being new to platform I had non-idea what crec meant. It's on me. Haven't been on FB since 2016, also on me. Is info posted anywhere else? I am in there now and would love to finish the job.

[@AudiC7Owners]

Unfortunately no. Just in that group

[@tb3780]

@@AudiC7Owners Understood. I would like to thank you for so much excellent content. I ended up buying tons of parts from FCPEuro, 034, MercRacing, and was able to do all the installs myself thanks to your DIYs. Thorough and clear explanations, good camera work, just perfect. I will bank up the PCV relo and catch can parts until I have cause for pulling the SC. Again, much appreciated!

[@AudiC7Owners]

No problem man! Happy to help!

[@israelantoniomunozmatos8345]

Thanks me have one Is

[@keepthinking2666]

Isn't it funny how it takes us normal people to fix Audi's over engineering on some of these things? It's like this PC v. And the thermostat and the water pump should all be located on the top. Front or outside, easy, can't speak. As we know, they're gonna fail every single time, maybe even multiple times

[@AudiC7Owners]

The thermostat isn't a fun job, but the water pump is fairly easy to do. Don't even have to remove the supercharger

[@sebastianlorenzo4935]

Nerds 😂

[@Syfy86]

Any updates on the bolt on kit? Are you near ct?

[@AudiC7Owners]

With the full parts kit from mercracing it is a bolt on procedure, but you still have to buy parts outside of the mercracing kit. And no I'm not
