I found some plastic chips in the thread hole on the valve cover that caused extra time and work to clean it out. This must not happen to the quality part like you sell it. Poor final QA Inspection indeed.

not fitting item of my order
this item did not fit to my Nissan Sentra - it has to be returned, but still waiting for a shipping label. This return is taking too much time to be completed

No more leaks
No need to pay dealer prices. The valve cover and gasket fit great. I was getting oil in the spark plug tubes, but it has stayed oil free since putting this on. It was easy and cheap and works. Nothing else needs to be said!

Did the job well...
The 2002-2006 Altima has issues with the small gaskets that surround the spark plug wells. They deteriorate over time and allow oil to seep beneath the coil pack boots, which cause spark plug misfires, followed by rough idling and lights up "service engine soon." These 4 gaskets cant be replaced because they are built in to the plastic valve cover, in which the whole set-up has to be replaced. So far, so good. No more issues with misfiring. I pulled the coil packs 10 days after installing this new cover and no more oil in the wells (previously, the 1st & 3rd wells had 2 inches of pooled oil.The pooled oil also deteriorated the coil pack boots which also needed to be replaced. A-1 gave a great quick video on proper installation and torquing, so 10 days later, there were no oil leaks from the valve cover gasket either. The cover came with a new PCV valve along with the main lip gasket. However, the main gasket was about 1/2" too small, so a day before you install, I recommend you insert the gasket into the underside and you will need to use gasket maker and vice clamps to hold it in place after stretching out the 1/2". Thats what I did and no issues or leaks!

Decent product
Its always easy to order and shipping is quick. The gasket that came with this set was kind of thin and blew out after I replaced it. I ended up buying a thicker gasket at a local shop and it has been fine since.

Not good as I thought
I bought a valve cover from 1 A auto. I put it on my my 2006 Nissan Altima. When I start the car it start leaking. While tightening one of the ignition coil holding thread (for the nut) pops up. So I took out the valve cover and installed the old one. After that it was fine. I wasted $53.00 in vain. I think it is poorly constructed.
