"A refund or the second part I paid for would be nice... Update: Changing to 3 stars."
"After a couple of YouTube videos suggesting that some folks still had leaks after replacing this Dorman part, I expected they had damaged the manifold itself when removing this cap."
"My only downgrade is that this part differed from original in that the flexible membrane was attached to the valve body on the original and this replacement is not."
"spring just wasnt right (honestly forget if it was too strong or weak but a quick search online will confirm they all are like this) so just make sure to reuse your old spring if you try this and it doesnt quite work right, try the old spring before deciding part is bad."
"I replaced this on a 2011 vw jetta 2.5L had a p2178 rich condition bank one on idle."
"I did get a check engine light and code for running too lean in the first mile or two after installation, but I think the rubber just needed to get heated up and broken in."
"It lasted approximately 5 months then the car started throwing a check engine light."

Mine was old and brittle - and it broke off when I tried to remove it....such that I had to carefully (and painstakingly) fish out the pieces that fell in the valve cover port. The new rubber one fits easily and seals great - and prooved that even this small job is worth doing right."
"In the 5VZFE, the grommets are notorious for breaking apart when you try and pull them out meaning you will have to replace the grommet and fish out all of the tiny rubber pieces."
"If you pull straight up (like I did), there is a good chance the rubber grommet will shear in half, leaving a little rubber ring in the top of the valve cover."
"make sure you buy the grommet for it as well as the original that is in the vehicle should already be deteriorated."
"Grab a new grommet as well, my old one crumbled when I replaced the PCV valve."
"fits perfect,don't forget the rubber gromet."
"Works great."
"OEM (metal) part from Toyota for a 1999 4runner which is much better than any of the plastic aftermarket stuff from the large distributors."

"This little part made a HUGE difference in the way my Honda preforms."

"This part is located just below the orange oil dipstick."
"Then, after ruining the bolt, needed to mock up my own via the hardward store. Word of warning - be very careful in removing this part to not strip the head of the bolt."
"This fit my 05 Honda Accord V6, easy replace just take off a screw and change part."

"especially for a ford mod motor or chevy LS (these engines have a decent amount of blow by factory)."
"After having been installed for about 6 months, there is a touch of oil in each bulb, so whatever it does is working."
"Installed between my engine and carb."
"I installed this on my Cadillac CTS to try to reduce valve carboning due to ingesting oil (this is a common problem on direct injection motors)."
"The head has no threads for the machine screws that are used for the included mount..."
"although this did not fix the problem, it does keep a good deal of oil out of my intake system and out of my exhaust."
"The main problem I had with mine was the holes on the top that the bracket is supposed to bolt to but wasn't even threaded."
