VALVES

[TURBO100]

I have been told that the 2UZ doesn't need the valves adjusting, EVER! I have a late 2003 4.7 LANDCRUISER and it seems to me its getting a bit puffy. Non VVTI,

The early 2UZ's had shim under bucket solid lifters, so the valve lash definitely needs checking/adjusting once in awhile.

Something in the back of my head tells me the later 2UZ's (maybe the VVTi models?) had self adjusting hydraulic lifters but I could definitely be wrong on that....
