Hi,

Just replaced the valve cover gasket on our 94 Nissan Altima GXE. Used a Mahle kit. It was a successful repair. Everything went back together as planned, but...

The problem:

One of the valve cover studs came out with the nut. Tried to use two 10mm wrenches to get the nut off the stud so that I could replace the grommet, but the lower nut on the stud was rounded a but. Rather than try harder, to separate the two, I cut my losses and used some RTV on the old grommet and installed the stud back into the cylinder head to the 95 inch/lbs specs per the manual.

No leaks. :thumbsup:

That said, I would like to replace the stud and nut so that I can replace the grommet the next time I replace the valve cover gasket. To do this I will need to replace the stud and the nut--as the two seem fused together!

Can't find a part number for the stud/nut or aftermarket part.


Any suggestions on how I can replace the stud/nut?

Thanks,
Matt

Just unscrew the stud from the head and replace it with a used stud from a junk yard.

Just a tip: If during the removal of the original stud, the threads in the head get messed up real bad, you can use a heli-coil thread repair kit to restore the thread.

The nine outer studs are Nissan # 13508-1P100 and they run about $2 each at the dealer. The two middle studs are # 13508-1E400 and they are about $4.50 each at the dealer. The nuts are also about $2 each and the part # depends on your production date:

06/92-07/93 is # 01217-00181
07/93-07/94 is # 01217-00221

While the salvage yard is an option, it might cost you more in the gas to drive down there than to just purchase new ones from the dealer!

Thank you!!!! This website is an asset for those of us with the older Nissans! Looks like I need the 01217-00221 nut.
Just ordered 10 of each!

rogoman,

Thank you. Was hoping the part was still in-stock at the dealer, but repeated google searches for part numbers yielded no results. Glad I didn't have to resort to junk yard searches. I ended up buying a whole new set of studs and nuts. Nothing like starting a project and not being able to finish because of broken/rounded fasteners!
