99 LS400 Valve Cover Gaskets
Hello. I have a 99 LS400 with 145k miles.
Saw oil leak on and around valve cover gaskets. Had to add 1/2 quart engine oil (been 2k miles since oil change).
beside 2 gaskets and 8 spark plug tubes, what else I need to purchase?
anyone have part numbers for them I can use?
Thanks.

I can't see anything regarding the "spark plug tubes" even on the full rebuilt parts list.
The valve cover gaskets are
Gasket Cylinder head Cover 11213-50030
Gasket Cylinder head Cover no.2 11214-50010
Both priced at $29.80

For my '91, part # 11193-15010 is for the "spark plug tube gaskets", which is probably what you mean.
There are also # 90210-07001 Valve Cover Washers (16 of them - one for each screw).
Again, these are for my '91, your year's parts may be different.
If you're buying a lot of gaskets like this, it is usually a lot cheaper to buy an aftermarket kit that includes all of the above. Gaskets are one thing that I would trust aftermarket parts to do well.
Whatever you do, be sure to torque the valve covers carefully.

did you try retorquing the valve cover nut bolts? I retighten mine and it works. Try that first and see if it work depending how bad your leak, if it really bad...move forward replacing them. The driver side is a lot easier to get to than the passenger side gasket ( a little more involve) but not too difficult.

Check rockauto.com for the valve cover gasket. Their sets include the 8 spark plug tubes and the 16 grommets. They have a Beck/Arnley kit for $47 or a Fel-pro for $37, + shipping of course.

May as well get a PCV valve too, and a throttle body gasket, because it will have to come off. Depending on the state of the vacuum lines, a few of those may need replacing as well. And don't forget the Form In Place Gasket for around the camshaft bearings.

The vacuum lines will be another problem because at this time they a hard as a rock. you will know this after the work, also the ignition coil harness clips will break easy.
