hi all,
i have a 93 fzj 75 ute with a 1fz fe motor. pre update(air flow meter. dizy etc)
the problem i have is when i undo the oil cap the engine stalls . the motor runs very
well otherwise. ive had the mech go over the motor everything is within specs. i should mention ive checked a bleep load of other 1fzfe's none of them do this. ANY SUGGESTIONS.

Hi Bundy luver
Some petrol engines have various hoses going back to the rocker cover from the carb for emission control purposes, depending on the engine some have low pressure flow some are under vacuume ( something to do with burning crank case gases and not emitting it to the atmosphere ). Not very familular with that engine, does any other hose run to the carb?
Is it blocked ? Perhaps removing the cap changes this flow causing disruption to the carb?
Just a guess. I presume its a Bundera by your name and not a landcruiser but try
www.lcool.com.org its a Landcruiser owners web site.
Good luck. TPM

the 1fzfe is a efi motor. their r a couple of hoses that go to the pelenum chamber to the rocker cover but only one has a mechanical device. (pcv) which is working.

Perfectly normal its a closed loop system your creating an air leak.
Most petrol engines do this now even if you take the dipstick out the same thing happens.

You have a air leak into the engine from your inlet manifold. xf falcon efi engine was the only engine to stall when the oil cap was removed.
