My 92 4tunner has had leaky valve cover gaskets for a little while but I feel like its got bad enough to need replacing so I'm trying to get a part list together will I need anything else added to my list or anybody suggest anything else? Also can someone tell me the torque specs or a online manual I can download. Thanks for the help

Pcv valve
PCV Grommet
PCV hose
Valve cover gaskets
Upper plenum gasket
Black rtv

 

Try the FSM link in my sig below.

 

Alright thanks that's a lot of info there

 

you will also want to have some brake cleaner on hand to clean the mating surface before you re-install the valve cover gaskets, and possibly some spare vacuum line to replace any that need it.

 

Ok I'll add that to, hopefully the vaccum lines won't break I'm gonna try to just flip over the plenum instead of unplugging everything

 

Be careful raising the wiring harness to slip the valve covers...the protective plastic covering will be quite brittle.

 

Ok thanks I think I read wrapping them in tape helps to keep them from breaking and if they do it'll hold the pieces from dropping in the motor

 

The PCV hose is molded (and a dealer item). You can try a piece of plain hose, but it will kink. The dealer hose is not expensive.

Whatever you do, take a few minutes first to write some notes about all the vacuum connections to the plenum. You don't want to get half-way through and then start pulling hoses. And I doubt you'll be able to "flip" the plenum with the PAIR valve hose still connected.

I use a heat-gun (a hair dryer is enough) to gently warm that old rubber. It makes pulling (or pushing) a hose much easier.

Last, be careful around your TVV (Thermal Vacuum valve) in the back (follow the line from the Evap Canister). The plastic top (with two hose nipples) will be very brittle, and the too much bumping will snap it off.

 

Yea you take the hard lines off and flip it on the passenger fender or so I read but if not ill take pictures and notes, ill defenitly get the molded hose I don't wanna have to dig back into it just cause I wanted to save a couple bucks

 

You might be causing yourself more problems by trying to take a shortcut by not getting the plenum out of the way. A few minutes of taking pictures and labeling a few things will probably save you a few broken vac lines, connectors, and cold start fuel line. Trust me, you don't want that to be damaged. Cheapest internet price I found for that was $80.00.
