Setting Valve lash, on the 16 valve Suzuki SideKick. G16B ONLY !  or Tracker !  
All Torque's here, are for 96 , 1.6L SOHC 16valve motor;

See Cam below?, set the lash on the heels , never on the lobe sides. (the rockers are missing for clarity!)
The heel is  perfect simi circle and lash does not vary here. (cam not wrecked, sure)


Assumptions:
You already know how to use a feeler gage.
The distributor "disty" is timing correctly  (rotor at 1pm per FSM at TDC)
The cam key is not sheared or some previous owner(evil) didn't time the cam using the "I" slot.  DO NOT USE "I" marks or SLOTS ! Timing the CAM.
The crank key is not sheared. (hidden under the crank cog is damage?, LOOK !)  No body reads  1996 published TSB's , seems so. 
The Timing belt is timed exactly , not slipped.
If any of the above are wrong, stop and correct that now.  
Rules:  CW = Clock wise,  CCW = Counter clockwise (facing rear of car)
  1. Never turn the engine over with wrench using just the cam bolt.
  2. Number 1 cylinder is the front cylinder.
  3. Always spin crank cog , CW, less you risk getting  the crank 17mm bolt loose.
  4.  If you find the lash changing during a validation of lash  , you have set the valves , not on the heels or, a serious mechanical failure is here.
  5.  In each step you must tighten the cam  rocker set screw jam nuts, to factory spec. "Cam valve lash lock nuts.....    11 to 13.5 ft/lbs or     132 inch/lbs"
  6. You dont need special tools, all tools mentioned here are to explain the tools shown in the FSM, I ignore them.
  7. Do not rely on the Disty rotor location or HV wire rounting, for this procedure.   (or risk FAILURE and burned valves)
  8. The FSM uses the assumption, that all things are perfect, sure in a factory , perfect happens, but in a real world, NO!

The Lash can be set using 4 different procedures, called ways, and way4 works even if the cam is timed wrong !
The Best WAY is that way that never burns up the valves. The be, the lobes way.
Way1:  The 2 stops way.  The FACTORY FSM way.  (cam not timed right is failure here)  This is the fastest way , per FSM.
The Suzuki factory FSM way with  just 2 crank turns ( fails if cam is not timed correctly)  See full  Factory way 1, here

Way 2:  The 4 stops  way( the crank fires every 180 degrees of rotation, 1,3,4,2 ) 
 (cam not timed right is failure here, same for crank key, same with the infamous crank pulley internal rubber has failed and is loose)
Cam Cog not exposed. (cover on Tbelt not removed)  I'm trusting all keyways in the engine, here.
The 4 stop way, I first put a chock mark on #1 crank pulley edge "V" mark, then put 1 more mark at  180 Degrees  (1/2 turn around) on the same pulley crank. (about)
The #1 mark is for #1 firing and #2, the rockers are on the  cam heels  if #4 is on heels, now,  I then t rotate the  crank 360degrees and now #1 is firing. (#1 rockers on  cam heels)
We set lash for Each cyclinder   in  this order, 1, 3, 4 ,2   (ignoring the distributor , totally)
Turn the crank only Clockwise. 
#1 crank 'v' mark at TDC 0,  cams on heels #1 , set lash on #1
Rotate crank 180 degrees CW set #3 lash.
Rotate crank 180 degrees CW set #4 lash.
Rotate crank 180 degrees CW set #2 lash.
your are done.


Way 3:  (if the cam key (slot E) is sheared, this fails too. but the crank key can be sheared and lash will be good ! and the crank pulley rubber bad)
The CAM COG wheel must be exposed, if not skip this way3.
The cam fires every 90 degree's.
This way 3 is the same as #2 , but this time all  we do is Gander at the "E" SPOKE MARK, on the front of the CAM COG wheel.
This can be done in Any order at any time, any valve, suspected.
  • Set #1 rocker valve lash with E Mark at 6pm   (I look at the cam lobes and see they are on the heels, if not , the cam key is sheared or indexed wrong)
  • Set #3 rocker valve lash with E Mark at 9PM
  • Set #4 rocker valve lash witih E Amark at 12pm.
  • and last set #2 rocker valve lash with the E mark at 3PM

  Set the lash on the cam heels and never ever be wrong.

Way 4 , (LOBE HEELS WAY ONLY) This is the only way that is 100 % failure free, for LASH ONLY.
This way is ,  just rolling the crank CW ,  and you, watching the lobes and when the lobes are on the heels? , then set the lash, 
This is the no books, no tricks, no cheating way, it is taught in all ASE classes, for checking cam  timing or lash on any 4cycle otto cycle engine.
All you need is a feeler guage, and eyeballs on the cam lobes, to do the job.
Why do this?, if you have issues with the motor, doing this way, prevents valve burn up, no matter what is wrong with keys and rubber crank vulcanization. You can do this , then conscentrate on timing, bad keys and what not and get compression over 170psi.


Suzuki WAY 1 Assumptions:
You read the instructions on how to use a feeler gage.
and:
You know how to set lash with a feeler gauge and can remove and replace the valve cover gasket ( with a new gasket)
You checked the crank bolt , for 94 ft/lbs of torque (CW facing pulley) because they all seem to be falling off. (TSB) Horror

If you've never set the valve lash before, then  Google " setting valve lash", this is common information. The below is unique to this motor.

The FSM shows using a special feeler gauge, to set lash , no you  don't need that, just use the cam to rocker juncture to set lash. and avoid this tight valve tip , area totally.
Do not try to put a feeler in lifter gap just below.  See the 2 red arrows in the below head photo?   see lash THERE. x16

See Targets of Opportunity.


Pre-staging:  
Pull off the main induction tube, 4 hose clamps and 3x , 12mm headed bolts. and the Induction tube mount bracket.(3 more bolts)
After pulling (twist first) the spark wire boots  out of the wells , I always blow out the pits (wells) with shop air,  I just hate sand in side a motor.
If the wells are full of water , then consider stopping the  use of the pressure washer. If full of oil the gasket is no good. You have a new one.
Remove the 2 water tubes to the induction heater pipe (plug them) and remove PCV and 1 breather hose from the same pipe, tie them back.
I leave the throttle cable attached, but that is your call.
Pull the Valve cover  , there is pry point at the top right corner of the cover (below, at the gasket juncture)

Key points are,  that you set the lash in groups.  1,2,5,7 is the first group (Drawing #1 below) , be sure you are at TDC 0 degr. and that valves at Intake group 1 are loose.
In fact all valves at #1 cylinder (front) are loose now. And must be so.
If valve group 1 is not loose, rotate the crank CW , 360 degress and it will now be loose.
If not loose now ( the lash) then something bad is wrong. ( Timing belt slipped. Cam wheel cog key sheared? , etc?)

The Procedure: WAY 1, the factory way.   Most  Torque spec.'s are here.
  1. Gain access to viewing and touching, the distributor and valves. ( I recommend timing the distributor now, if this has not been done yet)
  2. Find your crank shaft timing marks and mark them with white paint,on front cover on newer cars.
  3. Get  a new valve cover gasket , because we never reuse gaskets,  (FelPro has a nice set) The old ones will be hard and cracked, I bet.
  4. Remove the spark plug wires from the spark plug tips, mark them so you know where they go back.  (can't be mixed)  Twist them first do not just yank them.
  5. With 17mm wrench turn the crank shaft big end (front) bolt Clock wise , until the Timing mark on the pulley (notch) aligns perfectly with the timing scale molded into the front timing belt cover.  10 |||||5 |||| 0   <<< something like this. set it to 0 degrees.Align it to 0 DEGREES
  6. Remove distributor cap , mine has 2 screws. Mark #1 spark plug wire on cap with white paint or tape. Also mark the Distributor base for #1.
  7. I never look at the Disty, when doing lash, I only look at Crank TDC , Cam marks and the cam lobe positions, with a careful eye.   I find #1 firing and jump to step 13
  8. FSM states, Look at the rotor, is the rotor at 1 pm ? (I never do this) , see note 1 for corrections)  
  9. If the distributor was timed wrong or to different posts, then either correct that, or see my alternate settings Note 1, and jump to step 12 when ready.
  10. If not at 1pm  (or not at TDC 0 #1 firing) then rotate crankshaft CW ! 360 degrees ( 1 full turn on crank) and aligned again to 0 degrees.
  11. Is the Distributor rotor at 1 pm. NO? then someone set it wrong.  You have 2 choices now , time it correctly or just mark the rotor to the body with paint.
  12. Alternately to steps 6-10 above ,just find the loose valves , on #1 cylinder or  #4 , if #4 is loose then turn crank 360deg more CW. (1 more turn). Now #1 is loose.
  13. You now think you are at TDC 0 #1 firing , you now need to check that the valves are both closed at the front #1 cylinder pair.  Intake and exhausts valves #1  must be on the back side of the cam lobes and lash must be loose. If  this isWRONG, then the cam timing is wrong.  You may need to loosen the valve adjusters on #1 if they were too tight, 
  14. We are now sure that  all  #1 valves are closed fully on top of compression stroke ? firing ?, then proceed.  Just look at the cam or watch its action.
  15. Note the Distributor can be timed in 4 positions, and doing so, is really bad practice , even though it runs, just feel sorry for the next poor guy, trying to sort this, deviance. If you find any issues here , then re-time the cam and then re- time the Distributor, then last set the lash. 
  16. The cam must be timed correctly before doing the Valve Lash.  ( timing the Distributor can be done later if you follow note 1 rules)
I never look at the Distributor if my cam timing and distributor are known to be perfect.  I just set TDC 0 deg. #1 firing by just looking and feeling the #1 valve lifers.
Drawing #1:  
(this way is the Suzuki FSM 2 crank position way) you don't need to do it this way , you can just walk the crank and cam 1,3,4,2 and set valves "old school")
Rotor at 1PM !
  1. Next, adjust all valves marked, valves with a feeler gauge. (doing the first 4 groups, see them?)  I use the "Go , NO method",  .008 don't fit and  if .005 don't it needs adjusting, and only checking on the back sides of the rockers at the cam lob junctures, only !
  2. Adjust valves groups (sets) 1, 2, 5, 7  (not cylinder numbers,but  group numbers)  See lash tables at end of document.
Drawing2:

  1. Set the lash on each set 1 at time and do not touch the others yet, just set only 1, 2, 5, 7  (this are set numbers , NOT cylinders)
  2. We are done with those 4 sets , now rotate the Crankshaft 360 degrees CW and stop at TDC 0 again.  (CW = Clock Wise)  #4 is firing and loose.
  3. Adjust the  valve lashes for 3, 4, 6, 8  and tighten all lash nuts, to 133 to 168 inch /lbs. ( each valve lock nuts is tightened as you finish each)
  4. Do not go back and re-touch the other valves , unless you rotate the crank , 360 degrees again. (avoid CCW rotations)
  5. This process is just 2 steps, at two TDC 0 deg. locations on the crank.  #1 firing and loose valves then #4 firing and loose valves.
  6. The first step is really TDC #1 firing (set 1, 2, 5, 7)  and the second is TDC #4. firing (set 3, 4, 6, 8)  FYI !
  7. You are done,  all rocker jam nuts are at 13 FT/lbs ( or 155 inch/lbs, max) be sure lash didn't change after Jamming the nuts.!  < experience talking......
  8. Reverse the procedures above , gaining access to the valves.  Cover , brackets, Induction tubes.
Firing order is 1, 3 ,4 ,2  the engine fires every 180 degrees.

On my 96 Kick, I set the lash to .006 on all valves.  (middle of spec. range) ( if checking, last I use Go, NOGO method)
The last bit of information needed , is the lash spec.s and the valve cover torque , below for your year.

V
alve Cover bolt torque is low as, 36 inch/lbs or 3 foot/lbs  ( on some years)
 My 96 FSM  shows contradictory data,  89 in/lbs on one page and 44lb/inches on page 6a1-61.
( My 95 FSMTracker) show as high as 89 inch/lbs ,  on page 6a2-77)
I  use 44 inch lbs max. for my 96, as stated in my 96 FSM.
Careful here, on VC bolts (8mm head) times 6, use as little toque as possible and make it firm.  Never use  a Ft/Lb torque wrench at 3 Ft/lbs , use an inch/pound wrench!
The VC bottoms out in the 4 corners and so over tightening will never stop any leak.  Forget that idea, please look at the corners, and see the stops?
Go easy with these tiny screws on the VC.
