SOURCE: Motor g16A 16V, Borken cam belt, has it bent the valves ?

Do not attempt to start the engine under any circumstances until you have carried out a few tests. IF you dont have valve damage replacing the belt and trying to start the engine could cause serious further damage.
Replace the belt and make sure the timing is perfect, you might need to rock the pistons back and forth via the crank pulley in order to fit the belt if the pistons come into contact with a valve or two. Once you have the belt fitted and the timing right remove the spark plugs and slowly turn the engine over by hand, not with the starter motor. With the valve cover removed and with someone turning the engine by hand you should be able to see any valves that are not operating correctly. If any thing doesn't look right then you will have to investigate further by removing the cylinder head.

SOURCE: exhaust smokes when engine starts

Most common reason for that is worn valve stem seals and or guides or gunk buildup in the cylinder head blocking oil return holes.... Or, broken piston ring or burned piston lands. (use compression test to verify that) Knocking can be from oil detonating in cylinder or bad rod bearing etc.

SOURCE: What are the valve clearances

For a 1999 Vitara the clearance is
intake (cold motor) 0.13 - 0.17 mm
exhaust(cold motor ) 0.23 - 0.27 mm

Head bolts
Apply engine oil to cylinder head bolts and tighten them gradually as follows.
(1) Tighten all bolts to 35 Nm (3.5 kg-m, 25.0 ft. lbs.) according to numerical order in figure.
(2) In the same manner as in (1), tighten them to 55 Nm (5.5 kg-m, 40.0 ft. lbs.).
(3) Loosen ail bolts until tightening torque is reduced to 0 in reverse order of tightening.
(4) In the same manner as in (1), tighten them to 35 Nm (3.5 kg-m, 25.0 ft. lbs.).
(5) In the same manner as in (1) again, tighten them to specified torque.
Tightening Torque (a): 68 Nm (6.8 kg-m, 49.5 ft. lbs.) dak408_3.gif

did you have the head completely done and if so the valves may need adjusted and is the car getting gas.

What could make my 1993 geo tracker flood 1.6

the G16 engine, floods.
there are 2 engines, G16a and b.
8valve TBI and the 16v MPI engine.
(EFI on both are radically different.)
this pages shows all 3 levels of diagnosis
3 causes. physics.
14 causes.
and then the full list.

to find the cause takes tools.
got tools?, what to buy them.?
or just guess.?

here ill guess (useless)
1: the FPR reg is stuck closed, and fuel pressures 2x normal an it floods.

got 50 more...

Is there a timing belt and performance difference on the 1.6L 16V engine type ? i was told that there's something to do with E/I position? sidekick/vitara 1994 lwb 4 doors if it matters.

no, the E and marks are for 2 engines.
E mark for G16B (16valve MPI engine)
I and E marke are for the twin cam engine, (see link for deeper facts)
if you use the wrong marks, the engine will not run
and compression falls by 1/2 from 180 psi to 90 or less.

the G16A is different 8v head, yours is the 95HP, 16valve head.

covers all ways to do it right and wrong.

Any codes set? If not, check for spark at plugs. If none, could be coil/module, cam/crank sensor but last two usually set code. May be worth reading codes even if no check engine light on. Parts stores can often test modules for free.

What could cause a1991 suzuki samurai to have no fire from a new coil?

no spark from coil directly?
is the cam turning, is the dizzy rotor spinning. ????

check all fuses first. Ig-coil, FI and dome.
then using diagnostic jumper wire or fuse, (as approp)
crank engine look for code 41 o 42.!!!

USA cars , answers only
our cars are all EFI that year.
no engine swaps to Suzuki G16A/B sidekick or tracker engines.!
1: engine cranks
2: no spark
3: The ECu makes spark
the CMP sensor in the DIzzy , (never fails if rotor turns, does rotor turn, if not cam belt igored and now snapped.)
the cam turns. the CMP fires. the ECU takes this CMP signal
and fires the ignitor next to coil and the coil charges, and release and BAM spark.

that is it.
the ECU will tell you when the CMP dies or the Ignitor fails
why not ask it.
1: key on
2: diagnostic jumper in place (flashes 12s for ok)
3: crank engine,for 5sec, not 1 ,not 2.
3: release key not off.
4: see code 41, or 42, BINGO !@!!!!

1993 geo tracker idle up and down

HOT ENGINE? (ill guess hot)
idle surges.(hunts) (very simple reasons or very hard to find.
the car has 2 engines. G16A and G16B
they work totally opposite, (8valve and 16v)
the vin number tells you the engine type ,digit 8 is engine code
6= G16B 16v
U= G16A 8v
i have factory book. its in chapter 0 these facts.
the cause of idle surge and hunt are:
1: ISC failures. the ISC can stick partially open and then hunts.
clean it and test it . see videos of how.
2: engine running so bad the ISC can nOT regulate idle speeds.

#2 is caused by up to 50 reasons.
8v , air leaks, cause racing idle and iSC goes nuts.
16v , all air leaks cause lean and if too lean the ISC goes nuts.

by nuts , i mean it hunts or gives up.

the list is endless, but the tests are basic,
i cant help you because no engine stated.

ISC = IDLES SPEED CONTROLER (a system not just a PART)

g16a or b
the cam cog mark is at 12pm matching the same mark
at the back 12pm tins at rear of cam cog.
this mark is TDC #4 firing, number four.
pick 8v or 16v engine.

documented 3 ways, by page new page, by FSM and by instruction sheet that came with all new belts (GATES)

the cam cog has 2 false marks, do no use them
use all E marks. 16v and see 8v for its false marks too.
1995 had 2 engines, 2 EFI and 2 heads. as an option.
fact. G16A or B.

Number 3 and 4 are not firing from coil on 2002 subaru outback 2.5

its faulty coil.

Get the compression test done on each coil.these will let you know if its faulty coil or not.


It can be issue with spark plugs or faulty spark plugs. Also get the compression test done for cylinders. If any of cylinder shows low compression then required, then that particular cylinder will cause misfire.

Also get obd codes scanned, the error code will let you know which cylinder is misfiring or all cylinders are misfiring.


For your trouble shooting I suggest you to refer the help oinks below. It has step by step details for many engine misfire issues.
