I purchased aluminum valve covers because the plastic ones can warp and cause more leaks over time.
Looks like Honda 3.5 L v6 j series. Notorious for valve cover : pro tip when looking for possible locations of leaks always start on the top of car going down. Due to gravity everything leaking drips downward , anything under valve cover that looks questionable clean it up do the valve cover and reinspect next oil change.
Had my 2010 bought new in 2009 Mazda 3GT valve cover done at 119k miles when Mazda tech noticed leak when changing oil, with points check. $450 with oil change and tire rotation.
It's really a great car overall..I used mine to drive the family around and still did autocross with it. Their are some areas like others have mentioned to get checked out.
The valve covers may leak and drip on the plastic water pump housing causing a leak. If that hasn't been upgraded to the metal one get that done. We went through two of the plastic ones under warranty. Other than that I had no issues with the car.
Buy a new valve cover. If it isn't cracked now, it will be soon, and/or the PCV diaphragm will fail.
From my experience uro is alright a lot of people dog on it but ive never had any issues personally but they are just like an ok brands not great not bad just mediocre. Vaico has always been very premium feeling in my opinion, never had issues, always feels pretty high end, nice packaging, nice hardware, premium feeling.
I\u2019m a BMW Master Tech. The N52 is not reliable. Myth spread around the internet. It\u2019s just more reliable than the engines BMW released around 2006. I do thank all of you N52 owners for all the money. So easy to work on and they leak oil every 50k from either the valve cover, ofhg, and/or oil pain.
I have had one the ongoing maintenance is the worst of any vehicles I've ever had constant oil leaks valve covers and intake great to drive fun car but it will eat you out if house and hime
Paint flaking around the rear window and valve cover leaking. Usually in the back left in my experience.
as a huge Mercedes fan, NO THEY AREN'T RELIABLE! Shit breaks, there's miles upon miles of electric connections, and they like their maintenance. My cousin owns w210 as a daily, and it caught fire when oil from the valve cover seeped onto exhaust manifold.
