replacing valve cover gaskets
 

Hello all, new to the forum and to 4runners. I recently traded in my Tacoma for a 2010 4runner w/ 211,000 miles. I changed the spark plugs this week and noticed oil accumulation in several of the spark plug holes. No signs of oil burning or head gasket leakage from what I can tell. I'm led to believe a valve cover gasket and spark plug gasket job is in order. Before diving in and ordering parts, I just wanted to confirm the part numbers I have here are correct. Also, are there any other parts or tools I would need or recommended for this job beyond basic hand tools. Any sealant needed around the valve cover gasket when replacing? Here is the list I have so far (my main point of concern was if the intake manifold gasket was the correct one as there were a few in the parts fiche to select from). I'm also planning to replace the PCV valve as a preventative measure. thanks in advance

11193-70010 x 6 (plug tube seal)
11214-31030 x 1 (valve cover gasket)
11213-0P010 X 1 (valve cover gasket)
17176-31140 x 1 (intake manifold gasket)

Keep in mind that the dual VVT-i 1GR has the VVT oil supply going through the valve cover unlike the single VVT-i so you may need the crush washers for the banjo bolts.

Good point! Thanks

Here’s a teardown of a similar but not exact 2GR.

Good luck with the job! In a sick way I love these kinds of projects.

the first 3 part numbers are what were used to replace mine and spark plug o ring seals. I did not require the intake manifold gasket to be replaced so I don't have that part for reference

In addition, 18 sealing washers were used 90210-06013 and I did the camshaft gasket at the same time

camshaft: 11159-0P010 x 4 and 90430-10024 x 2. I had this done at the dealer

Here’s what you need to replace

very cool video!

thanks, I've watched these!

thanks, do you remember if any sealant was used on the valve cover gaskets?

thanks, are the small orings circled in green part of the oil return system? Is that a possible source of leakage as well?

I am actually not sure if sealant was used. I don't believe it is required but the toyota FIPG or an RTV would work. the fipg will work both as an adhesive and sealant
