. ive been a member for a long time as ive had my MQ since 2015.
The tech advice is great and i was wanting to ask a few questions around an issue i have.
My mq puffs white smoke, only once and only at the end of my street when cold for about a month. once its warm it doesnt happen again. until last week when i drove home on a particuarly cold arvo. i tthought it was only doing it when i turned. i went home and noticed the overflow bottle was low, now i initially thought this was relevant but the weekend prior i removed my airbox and moved the overflow so it could have drained out.
i use blue penrite which i changed more than a year ago and when i drained it to pressure check the egr cooler it was more green than blue.
anyhow i thought the white smoke was due to not draining the catch can in time. but then moved onto egr cooler which passed a 20psi test in a bucket of water.
now ive removed the intercooler and piping and cleaned as there was a fair bit of oil in them.
after some forum searching i decided to look on top of the motor. around injector 2 there is a black brittle glass like substance, the heavy fitter at work tells me it could be carbon and diesel due to a bad injector seal. id like to know if these just fail or is there a chance its been installed wrong. last time the injectors were out were for valve adjustment 20k ago.
ive had mitsi replace a seal before when it was newish.
my local dealer cannot look till next wed.
i should add the ute runs sweet, never ever has gotten hot or more than half way in its life. i have a scangauge and watch it religiously. it starts fine and appart from the white puff id have never had a reason to check it. also last time i dropped the oil (one month ago) it had made some oil about 5mm over hi mark. i previously thought it was due to dpf burns (which i have never ever seen it do)
it as 159k on it now. should i prepare for bad news? also mitsi are the only ones to have ever pulled the top off. i do my own oils after warranty expired.
bit if a long winded explaination but the wait is driving me crazy.
