A week ago I found an oil leak from the cyclone separator in valve cover which was leaking oil around my coils, will this updated valve cover drink less oil? There looks to be a small design change, there's this plastic piece protruding out the back towards the AEM airbox. Part # 1 11-12-7-646-555
There is a TPS that has the red piece removed upon installation and a small black insert put in it's place..... Not sure why this step needs to be performed at the time of installation... Seems like it could be provided fully assembled right out of the box... Yes, your part number is the latest valve cover...
I have traveled 3000 miles on my new updated valve cover and just checked my oil today, there is no measurable oil level difference since I first checked my oil (using Craven dipstick) when I got it back from the dealer over 3000 miles ago! I currently have 48,416 miles on my 2007 MCS, still performs like a new motor! I'm extremely happy about this!
