Oil consume

[FJ60_cruiser]

Hi to you all.

in the last month my 60 has started to consume a lot more oil than it did on the past, but about a month or two it's been consuming 1ltr of oil each two weeks.
i was wondering what could it be. she have a burned valve and it doesn't smoke every time, only when the engine is cold.

Malfunctioning PCV?

Look into the valve seals. Old seals will leak oil into the cyl when the eng is sitting and the oils draines/pools on top of the head. The eng starts when "cold" and the collected oil burns in the cyl. After start up the seals - seal, and/or leak so little you don't see any smoke.

Time for a compression check. Might be worn out rings.

Positive Crankcase Ventilation. As I'm typing this I'm wondering is non USA Cruisers even have them. It routes crankcase gases from blowby back into the engine intake. If you have one, the side cover plate, below the spark plugs has a metal elbow attached to it, near cyl #6. It has a metal cartridge check valve thingy in it with a hose running up to the air filter. THe check valve can stick and cause increased oil consumption, or so I'm told. I'm not clear as to how the stuck valve gets moe oil into the cyls.
