Offroad-Express

Feel like an egg alright ...

So, on Thursday arvo, just as I pull into a parking space and slip into neutral I hear a 'pfft' sound from the engine bay - followed by lots of very milky smoke coming out of the engine bay right in front of the windscreen (FJ40).

I kill the engine. Check the bay - no signs of what broke: no burn signs; no liquid; no melted wires; nada.

With a sense of foolish bravey: I key the ignition and ... she starts straight off. Check the engine bay while she's running: no issues. Drive home. No issues.

Take her out for another check Thursday night just before it got dark and could see lots of smoke in the rear-view mirror. Pull up at the side of the road, pop it into neutral and stand outside the wagon and watch the exhaust while I pump the accelerator: lots of black BLACK smoke coming out the exhaust. By the time I got home (about 5 km's later) I'm pretty sure she was smoking out the exhaust just while idling (it was dark so couldn't see for sure). Haven't started her up today.

Also worth noting that when killing the engine she now judders noticeably.

So, being the impatient bugger I am and not wanting to have to wait until Tuesday to speak to a mechanic ... what's the likely damage done? And any ideas on costs to repair? I'm going to have to take the engine out anyway (consider it up-skilling!) so don't mind taking the time to do things in my own garage.

Appreciate all feedback.

Cheers and, er ... Happy Easter! ... I think

hmmmm ... lots of views but no posts ... c'mon - I'm sure a few of you out there have something to offer on this!

may be something easy like a cracked or loose injector line?? check them first then go from there

ps: only just found this post

Hi Ben,

didn't see your reply - still getting used to the slight change in format of this place!

Got the steering idler - thanks a bunch for that: when I get back down to Hamilton way I'll call you for that beer while I point excitedly at bits of your wakka and ask "how'd you do that?" / "what's that for?" / "where do I get one of them?"

Is the wakka certified and road-legal now?

There's talk of a diaphragm in the back of the injection pump that can go.

anyone got any ideas where (other than Toyota dealer) I might try for a replacement injector diaphragm?

Get the genuinue item if you are going to replace it. I went through two on my last 3B, didn't use genuinue one the first time and it only lasted six months

But my symptoms were different when my diaphragm was leaking on the injector pump. It would idle at about 2000rpm and slowly idle faster and faster as the thing split. Was always a fun day or two till it was fixed, braking to keep the speed down to 50kmph in town

apart from the last comment already up being the best one. you could all so try a diesel pump specialist? which big smoke are you in?

Thanks for that: sometimes you can get ripped off with the OEM stuff but in this case it sounds like it's best to go the OEM

I'm in Auckland but I figure that it's a pretty light part so won't be too expensive to get shipped from another part of the country - or even another country.

Any ideas who to try?

Who would ever have thought that you'd have trouble keeping the speed DOWN on an FJ40?!

Cheers.
