    I think i know the fix to your problem. Raise the revs to about 5500 with the clutch in and 1st gear selected. Dump the clutch and hold the steering at full lock to the left. It should start doing helis but if not give the clutch a little kick and it should be ok. Let us know if that fixes the problem.

    over-run eh? ok try this- on a hill downchange to hold a high revs with no throttle and crach it open after about 5 seconds. If you have a cloud of smoke it's your valve stem seals.

    just a quick price guide question...

    new clutch. 3TC/T50

    no labour. Can't seem to get a local quote online.. will be getting it next week....

    edit: not set on toyota part necessarily, somethin a little heavier would be good. Can only find yank prices, and postage is heaps.

    so dealio is, i have the 3sge beams in my 86 running.

    Its on blacktop quads running and adaptronic with a tune from an identical speced motor.

    It starts up fine, and idles well, but when i try to throttle it up it gets all emo.





    When it has a LITTLE tiny bit of throttle, it revs up fine, then stumbles back down like its hunting. Give it a bit more and it gets all shitty and starts to stall. Hold the throttle at the rev up tiny bit place, and it just revs up and down from about 1000 to 2000.

    Im not really sure whats going on, but need to get it going shiny people

    any help appreciated.

    could it be map sensor issues?

    Car model: 1984 KE70

    Engine type: 4AGE 16V smallport

    Problem: Car won't start. It's getting fuel, spark, injectors are pulsing and all wiring is where it should be. When the car is cranking it definitely doesn't sound normal. Me and my mates finally noticed noticed the knock pins on the cam gears were both at 12oclock and 12oclock respectively on TDC. So I'm assuming my exhaust cam is 180degrees out? Can someone confirm.

    Bare with me and my lack of knowledge but i've only just started learning about engines. My question is, to correct the problem will I be able to just say rotate the crank till the pistons clear the valves, rotate the exhaust cam 180 and refit the timing belt as per normal procedure?

    yep thats a problem, one should be up (inlet) and one should be down (exhaust)

    place engine at TDC, (good idea to check with a screw driver down the number one spark plug hole that TDC is actually TDC, i had a 4a spit a woodruff key and they harmonic ballancer TDC mark was wrong), remove timing belt, align cams with approximate knock pin locations, put gears on, move cams to timing marks, reinstall timing belt.

    sounds like a load sensing problem, check that your adaptronic is getting signal from your tps, and as stated map sensor. tps usually have to be calibrated to the ecu.
