Hey soon i am going to be doing my injectors and turbo and what not, and i was just curious, i have done my research and the manual sais to drain the coolant to take the top half of the manifold off? Has anyone done this job? How hard is it? What tools are needed? Is it time consuming?

Thanks. Phill.

draining the coolant is for when u take the cooling lines off the throttlebody/top half of manifold, u will need to remoove your crossoverpipe,throttle cable,all hoses/electrical earths, basicaly anything connected to the top half of the manifold, then theres a series of long bolts laying under the bottom section of the manifold, which transfer to the top. take em out then give the top half of the manifold a tap with a soft faced hammer to release its grip on the gasket, then its off! :sick: it took me no more then 30min, but im a mechanic :sick:

The first time i done injectors i didnt even take off the throttle body, the second time i did and it was much easier. If you are only taking off the top half of the manifold to do the injectors i wouldnt bother and just take off the throttle body as it gives you plenty of room.

i am a mechanic too, but only an apprentice :D so would just taking the throttle body off be enough to take all six injectors out? i was thinking the whole top half. With the coolant lines, wont you just be able to block them off rather than draining all the coolant?

Im trying to grasp how long this will take me and rob from creatd.. I was kinda thinking a whole week to do injectors ecu tune and turbo. Ecu and AFM i already know what to do, turbo im not too sure about, rocker cover gaskets i know 100% and plenum i kind of know whats happening.

you can actually replace the injectors without removing the TB or the top half of the plenum. once the fuel rail bolts are out you lift and slide the whole assembly forward.

the hardest thing to do is get to the clips on injector #4 & #5.

I am about to replace the injectors and this time will remove the TB as i think it will be easier.

wouldnt worry bout taking apart plenum.

have changed injectors in a few rb20s and only took off throttle body.

dont really need to drain coolant. just unbolt the tb and unclip lume parts. pull off the coolant lines and just let them drain till it stops (alot less than draining whole lot) just make sure no coolant goes in the holes while the injestors are out

pretty easy job mate, just fiddly (esp. clips) should take bout an hour to change injectors.

maybe a little longer for your first time

i wont be doing it myself. I will have someone who knows rb25s like the back of his hand helping me, so shouldnt be a problem, i just wanted to know the best way to take the injectors out. :laugh: thanks heaps.

    • Mixing things up - installed some leather recaros to match the leather seat covered rear seats. Interior looks pretty schmick now except for some slight wear on the steering wheel which I will monitor and address if it becomes worse or actually noticeable!

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
