HHR 2.2 - 2.4 Ecotec Whining / Whistling Engine Noise Solved! Oil cap and Dipstick Sucking Air! PCV? 

GIRL I BE LOOKING FOREVER!!! FOR WEEKS

What did the car do when driving would it not go into gear an just rev on the spot aswell ?

How do you check the transmission fluid level on a 2008 Chevy HHR?😀

​@@markcovington8159 lol you take it to a shop or drain it and measure it haha. Damned sealed system -_-

As someone who maintained mine for almost 13 years and got it with 53k and just passed 126k this morning the more I’m looking into these and doing more work myself they just seem to get filthy inside of the motor . I did only use conventional for the first ten years and synthetic for the last 3 . Also I did work only a mile away from home for like 10 of those 13 years so they were short runs which did not help but now am using it to ride back and forth from NY to SC twice a month and it’s doing great. I recently replaced the valve covers and spark plugs , changed fluids and filters except fuel since it is inside of the tank I may add an inline though that I can screws easily now that I’m thinking about that . I cleaned throttle body and MAF btw took bottle body a full week to correct itself after it was idling super high until I put it into D . I tried to clean the top part of the valve cover and the cams on the inside but without much success as I was too worried I’d break something . I’ve been researching and unless someone wants to spend about $400 for dynamic flush kit then flushing after adding about 20 % ATF then 4 qts oil after changing oil and filter then run it with the ATF inside for about 25 mins at idle and then change the oil again and me personally im going to add the BG oil change system the MOA the 44k the the EPR the fuel treatment flush that they give you if you bought the flush kit and then save $340 . I think it will end up working just as good too. I would make a video but there are so many on YT as it is and I don’t think I’d contribute anything new. Except perhaps other than maybe the idea of using the BG stuff that comes in the kit except for the flush itself and flush oil I’m doing the exact same thing except with ATF fluid . Sorry for the rant but I just think these engines run dirty no matter what the owner does like in the video how he said the owner didn’t maintain it well it looked like . I could almost guarantee that motor never missed an oil change . The ones. Who didn’t change their oil ended up in the junkyard already imo .

Same here, I drilled the small hole out in the intake for a 1/8" as suggested in some videos and cleaned it out very well. I had also just installed the timing and Ballance shaft chains. I thought the noise was due to the main seal or the Ballance shaft tensioner putting the water pump in a bind. But when I pull the oil cap or dip stick the noise goes away. I even bought a baffle oil cap to see if that fixed it. It didn't. So I pulled the timing cover off and checked everything, still making the noise. So I guess next I will replace the intake. Did that fix your issue? Mine only happens at operating temperature.

Crank seal also does this. There's a tsb

​@@jordanjustice6392 Any updates? Mine is doing the same things as yours.

Today my brother grabbed a hose the part is a mystery. When he moved the hose the sound stopped only to start again when he let go. 98 Firebid V6 3.8L. Some say it's MAF sensor some say Vac sensor. Mine is located to of engine on passenger side top of intake with a light whistle. Will post once figure it out. Cheers til then!!

@@jordanjustice6392 sorry i just seen this its been a while back but yes the new intake fixed the issue i guess i had drilled it out to big

Were you able to correct the problem?

That part is the intake manifold.

​@@ChadWilliamsFixesAllWhere is the link for the part you mentioned?

sad to say, some shady shop will charge people for parts and not change it, that's why I do minor maintenance myself, only major repair does my car go into a shop

Alternator? I have a similar noise that gets louder when I turn the steering wheel, even parked. It's definitely a noise that sounds like it's coming from the engine though, but it's high pitched. Would an alternator do that?

Looks like it

There's no PCV valve on Ecotecs

@@boosted2.4_sky I have the lnf ecotec. I had to remove the intake manifold to replace the clogged pvc valve. Then I bought turbo tech racing kit that allows service without removing intake manifold.

@@joegarcia3214 It's not a PCV valve.... It's a vacuum port...👍

did this ticking noise is pcv? have the same problem... tks!
