Re: back-fires and cuts off
Check the distributor to make sure that the rotor is pointing at the no. 1 cylinder when that cylinder is at top dead center on the compression stroke. It sounds like your distributor rotor is 180 degrees out of time. The engine will run but will do what yours is doing.

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.
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.
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)
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.
