3.6L LLT PCV Valve Breather Mod - Oil in intake tube GM Buick Enclave, Travers, Outlook, Terrain

7/64 Top 5/64 Bottom

[@m7mdm7md75]

Does it still work good ?

[@nkastis8211]

Thought i was crazy in video you said 7/64 on both of them but guessing thats a mistake and this is what you meant? Thanks!

[@joseecheagaray7620]

Owners of any gmc vehicles with this engine should start a law suit against gmc. It's a engineering screw up that causes all this problem. Falling timing chain, bend valves, etc. This poor design its causing big money spent for gmc car owners.

[@TheGivebackmyworld]

I have modified to make the holes bigger. Yes it worked as no oil in the intake tube. However, there will be another issue later. Since this PCV holes allow oil pumped through and finally end up in the manifold. As I experienced with rough idle after a few weeks, the air intake tube is still dry but when I removed the throttle body, a lot of oil found in the intake manifold right after the throttle body. I have replaced a new redesign valve cover gasket. I finally installed oil catch cans which I have seen my Acadia getting better gas mileage and responsive. kzbin.info/www/bejne/q3aodnysq9Klh7c

[@DIYwithPete]

H Dao yes I've seen the new design is covered to keep oil from going into the PVC lines. Unfortuanitly this was just one of many issues we encounteted and decided to call it a lemon and got rid of it.

[@kenrose1154]

This is informative...sounds like its a major problem

[@ItachiUchiha-lr3yr]

7/64 for the bigger single top hole & 5/64 for the two smaller holes on the bottom, try if possible to drill from underneath so you don't risk the shards of metal going inside and getting into your engine.

[@robertvale8662]

Why not change the video with a text caption while you're showing and telling the incorrect sizes so people don't oversize the holes? Not everyone will read your "corrective" comments!!

[@ncckirk]

You need to remove the pcv from the rocker cover to drill the pcv holes bigger. There are very good Australian youtube on how to do it.

[@mavx318]

Does 2012 Impala LT have the updated version? Thanks!

[@genemaverick5705]

Mine won’t come out , how do you get it out ! I’ve tried every tool to pull it out and it doesn’t come out

I have the same problem with my 2014 enclave.

[@dancurrier6421]

​@@jeanpierreremond2565in order to get it out have to take of intake and back valve cover and punch it out I had to do that to mine what a pain in the butt

[@tombuswell8991]

Hope this works on my 2008 GMC Acadia. Just did the mod. Question - I removed the old PCV with some difficulty, when I replaced it, it just slid right in up to the stop. Tried pushing further but wouldn't go. Is that ok?

[@robbypro3370]

I have a 2012 cts and have oil in my intake tube. Maybe I have an early production?

[@nickkrygier915]

Have a 2015 impala limited and the pcv valve still has that defect (drilled them out a while ago)

[@christineholby2403]

How often would or should you replace this valve? If you don’t make holes. I thinking I don’t want future issues. Hmm

[@freepressinsurgency428]

Good question.

[@ozzyosbourneandrandy]

About every 30,000 miles

[@DarrelllCampbelll]

Should I be able to look through it?

[@barryrenouf3450]

Who told you what the drill dimensions actually are?

[@jd5179]

If you don't have oil catch can - it will produce more carbon deposits to the valves since pcv holes is bigger .

[@TrippyWoodStock]

Can confirm. Catch can the PCV line that goes into your air intake. Catch can the PCV itself also. So 2 catch cans for best results

[@peeweeshine1562]

Won't this cause an engine size and blow the motor

[@jamesward5493]

Ring blow by is the problem, causes increased crankcase pressure. Get the rings to seal better is the real fix.

[@mastertech5036]

Low tension rings is the real problem. Ran into an article by GM explaining why the oil burning & blowby years ago. They were forced to go with low tension rings because of less drag & lower fuel emmissions, but obviously causes oil burning.

[@DIABLO_4_Tester_Sacramento]

So, this PCV valve stands for remove gases from crankcase? in the normal engine no gases will be in crankcase

[@rschneid1996]

Not true. Almost all gasoline and diesel engines have some combustion chamber gases in the crankcase. The gases blow by the piston rings and into the crankcase. The PCV valve is designed to vent those gases and remove the pressure buildup in the crankcase.

[@abdulazizkhalid434]

Thanks for posting But I have oil burn in my car and it's smoking from the oil gap and the car isn't stable I have checked it with obd and the code was p0304 Is this working with my car

[@Connected78]

7/64 for top hole For Buttom holes it' 5/64 drill just did that mod yesterday hope that helps

[@garytowne1548]

Spent the whole video drilling three holes. How about a little what is it where does it go.

[@AxelHavoc]

No offense but if you know about this part and the issues it causes and are looking for a solution you should know where it is on the motor

[@donlovelace2127]

This doesn't fix anything, it will let more oil into the intake manifold, intake runners and intake valves, add an oil catch can to help with this issue

[@rossevans1774]

This is a vent not a valve. Keep your oil clean and change your filter regularly from new and you won't have the problem!

[@christineholby2403]

Thanks for the info. It’s not corrected on the 2012 Acadia AWD. Fist a FYI.:)

[@Ronin-sh7pg]

you said 7/64 twice. What are the sizes?

[@ItachiUchiha-lr3yr]

7/64 for the bigger single top hole & 5/64 for the two smaller holes on the bottom, try if possible to drill from underneath so you don't risk the shards of metal going inside and getting into your engine.

[@francescolley7004]

Got your drill sizing messed up, "top part requires 7/64in and the smaller bottom holes 7/64in". Why it's taking so long for the US to adopt the metric system is baffling especially since every educated US engineer I've ever worked with is familiar with it and recognises its benefits. Anyway, back on topic. Drill the two smaller (bottom) holes 2mmØ and the single (top) hole 2.5mmØ. Of course this goes against GMs current tech advice that has introduced a rocker cover gasket that blocks off the rocker cover chamber completely and allows only 3 small 2mm holes into the chamber itself. My advice, it won't hurt to drill the holes out but more important to just check it's clean. And changing the oil more frequently is always a good thing.

[@maspaijolastrock8295]

Can just make bigger whole as pcv size ,,,???

[@DIYwithPete]

Not sure but if I'd say go with the redesigned valve cover to finally get to the bottom of this issue. This worked for me and others but it was just a poor design until GM fixed it be adding a plate in the inside ti prevent oil from going through the breather line.

[@jamiewehner3158]

Lol you said 7/64 for both drill bits. You ment to say 5/64 for the smaller bit.

[@williamgregory4442]

The size the drill is the same for the bottom and top.You’re saying the same size for both hose.One should be smaller then the other

[@bobspittle3201]

7/64 for the top hole. 5/64 for the 2 bottom holes.

[@bunol27]

I noticed too much wheezing sound when i modified the valve, i think regular cleaning of the pvc valve would help the issue as well. I bought a new pvc valve and the wheezing sound is gone.

[@-MrRichBiker1967]

How do you take out the PCV valve from valve cover? Do you just pull it?

[@Connected78]

Ricardo Borba After disconnecting the connector I used lockable pliers and put rag around it and wiggled it slowly side to side pulling up, mine came out fine..

[@TheGivebackmyworld]

The easiest method is using a door trim removal tool. It is like a flat head screw driver but the head is plit-up. It can be found in an auto shop or department store.

[@cesarcervantes1393]

I have 2014 camaro v6 do I need to do this?

People should not suffer to taking this out I have to take the whole part of the intake stop chess so I can change the PVC valve breeder that's insane

[@jra4585]

Did it work ?

[@DIYwithPete]

So far its been about a month and no more oil in the intake tube. I'll know for sure in about a few months after I check it out.

[@jra4585]

Peter Villalon can you do update vid

[@DIYwithPete]

For sure, I'll post it up when I check it out in about 2 months. That should give it enough time to be sure. But from reading forums (and I read many) this is one of the fixes GM did on their newer models. All GM did was make the little holes bigger so they don't clog up.

[@raadkins16]

Peter Villalon we just changed the spark plugs in my 2013 Enclave last night and I noticed oil in the air intake tube and on the connector that connects and sits above the PCV valve that you modified. So apparently mine must not have gotten the new design by GM with large holes?

[@holymackerel]

My 2013 Enclave had the smaller holes. I'm thinking about "fixing" it myself.

[@gregorykusiak5424]

I would’ve tried to find a straight through fitting to replace the factory “valve” than drilling it out. I also would’ve increased the ID of the hose to match the fitting - that crankcase pressure, as implemented by the factory, is a hinderance to fuel economy and power, but as shown here, helps them repair and sell a LOT of vehicles

[@-MrRichBiker1967]

OMG, exactly, read my post!!! I had the same problem!! it started sqeauling, like a pig as soon as I drilled out the holes!! never again.$ 23.00 for a new one, once a year is a mindpeace, trust me!!
