Back-fires and cuts off

4 speeds were very rare in American models. Tercel, corolla's smaller counterpart came in 4speed manuals but that was to suffice the 12valve motor. Call any Toyota dealer, give them the last 8 of vin and they can verify. Happy holidays.

if its back firing and there is no power the timing isnt correct the silencer wont mak a great difference to the back firing to me its the timing hope this helps ivan

white smoke means blown head gasket, do not run or will ruin engine

HI have you check your spark plugs to see or you only see oil build up on one side or the whole spark plug, if is the whole spak plug has oil around it is your ring if not sounds like possible valve guide worn down.

did you try replacing the sensor again? you could have got a bad one?

from the front looking back to the gearbox 1342.

1988, time to send it to the wrecker... or put in a crate motor.

how much oil is it burning between oil changes?

only a few ways oil gets burnt in the exhaust.

1) worn out rings - overhaul (running thick oil might help a little)
2) worn out valve guides - overhaul (running thick oil might help a little)
3) blow by is forcing it into the PCV system - overhaul
4) crack somewhere between the oil gallery and the intake... this usally run really bad though...


yep kinda sums it up.... overhaul (replace or wrecker)

Peace

THE spark plugs are 4 and the firing order is from the front (thats were the fanbelts are )and they are 1342
so the distributor the timing mark on the bottom pully and the rotor button point to the No1 plug lead and points just about to open,and the next lead will point to No3 lead ,and if so then you have the correct timing,,but the points set at 0.012" and the plugs to 0.025" ..And when engine idleing adjust timing on the distributor to advance (thats the oppersite to the way it fires and do it with the vacuum pipe off ,,then when engine runs good ,then tighten calmp and refit the vac pipe and test run.
