LS460 VVT system oil filters

[Peter67]

Hi

 

Thought I’d post this for information. The LS460 has oil pressure actuated variable valve timing on the exhaust cams (electric actuated on intake cams). Like a lot of these systems on Toyota / Lexus it uses a solenoid to control oil flow through passageways into a cam phaser allowing the timing to be changed by the PCM in response to power demand etc. These systems have a small Dedicated oil filter Which is usually accessible but on the LS460 its inside the valve cover in a small housing. The filter is a plastic housing with stainless steel mesh. There is a filter on bank 1 and bank 2. If you had sludge or a previous owner with long oil change intervals these could have a build up on them. It’s a few hours work to get to them if you need to but fairly straightforward.

In the photos showing the valve cover you can see the housing and I have a photo of the housing removed To one side and you can see the tip of the stainless filter screen

 

Bank 1 or Bank 2 both the same

Remove residual fuel pressure

Battery out

Coil packs out

High pressure fuel pump out

Wiring harness and connectors pulled back

Valve cover off

Remove housing and replace VVT filter

Replace All VVT system oil seals O rings and P Seal

They look similar, weird seeing the engine being chain driven earlier models were belt and direct cog drive on the cams.
