How to replace front cam shaft seal in Geo Tracker,1.6 liter engine

on what, spark or cam???
this engine 1 of 2, has cam belt timed
and a distributor timed... know that as a fact;. please.

that is cam. on 16v only
the pages there cover both engine,, G16a and B.
TBI 8valve and MPI 16v engine.

head gasket seal

1995 Tracker would have a timing BELT. Normal oil leak points (in order) on a Suzuki G16 engine are the distributor base (rear of motor), valve cover (top of motor), front main seal (behind lower timing belt cog) cam seal (behind the upper timing belt cog) and rear main seal. (behind the flywheel). I'd suspect the front main seal or cam seal. I use foot power to help find oil leaks.

When timing belts are installed, the normal position of the crankshaft is for #1 cylinder to be at TDC. Here is a picture of the timing belt routing and the timing marks.

thats why you line everything up BEFORE taking the belt off. Usually when the timing marks are "ON" the dowel pin or key for the cam will be at the 12 o clock position. Also if you have the valve cover off, both cam lobes for number one cylinder will be pointing down.and both rocker arms loose. it would be a good idea to adjust the valves also.

REMOVAL & INSTALLATION 1.8L Engine

1. If possible, position the engine so the No. 1 piston is at TDC.
2. Disconnect the negative battery cable.
3. Remove the timing belt covers.
4. Remove the timing (outer) belt tensioner and remove the outer timing belt.
5. Remove the outer crankshaft sprocket and flange.
6. Remove the silent shaft (inner) belt tensioner and remove the belt. Fig. 1: Silent shaft belt timing marks — 1.8L engine
   Fig. 2: Checking the silent shafts for proper positioning
   Fig. 3: Timing belt timing mark alignment — 1.8L engine
   To install:
   
7. Align the timing marks of the silent shaft sprockets and the crankshaft sprocket with the timing marks on the front case. Wrap the timing belt around the sprockets so there is no slack in the upper span of the belt and the timing marks are still aligned.
8. Install the tensioner pulley and move the pulley by hand so the long side of the belt deflects about 1⁄4 in.
9. Hold the pulley tightly so the pulley cannot rotate when the bolt is tigthened. Tighten the bolt to 15 ft. lbs. (20 Nm) and recheck the deflection amount.
10. Install the timing belt tensioner fully toward the water pump and tighten the bolts. Place the upper end of the spring against the water pump body.
11. Align the timing marks of the camshaft, crankshaft and oil pump sprockets with their corresponding marks on the front case or rear cover. NOTE: There is a possibility to align all timing marks and have the oil pump sprocket and silent shaft out of time, causing an engine vibration during operation. If the following step is not followed exactly, there is a 50 percent chance that the silent shaft alignment will be 180 degrees off.
    
12. Before installing the timing belt, ensure that the left side (rear) silent shaft (oil pump sprocket) is in the correct position as follows:
    1. Remove the plug from the rear side of the block and insert a tool with shaft diameter of 0.31 in. (8mm) into the hole.
    2. With the timing marks still aligned, the shaft of the tool must be able to go in at least 2 1/2 in. If the tool can only go in about 1 in., the shaft is not in the correct orientation and will cause a vibration during engine operation. Remove the tool from the hole and turn the oil pump sprocket 1 complete revolution. Realign the timing marks and insert the tool. The shaft of the tool must go in at least 2 1/3 in.
    3. Recheck and realign the timing mark.
    4. Leave the tool in place to hold the silent shaft while continuing.
13. Install the belt to the crankshaft sprocket, oil pump sprocket, then camshaft sprocket, in that order. While doing so, make sure there is no slack between the sprocket except where the tensioner is installed.
14. Recheck the timing marks' alignment. If all are aligned, loosen the tensioner mounting bolt and allow the tensioner to apply tension to the belt.
15. Remove the tool that is holding the silent shaft and rotate the crankshaft a distance equal to 2 teeth on the camshaft sprocket. This will allow the tensioner to automatically apply the proper tension on the belt. Do not manually overtigthen the belt or it will howl.
16. Tigthen the lower mounting bolt first, then the upper spacer bolt.
17. To verify correct belt tension, check that the deflection at the longest span of the belt is about 1⁄2 in.
18. Install the timing belt covers and all related items.
19. Connect the negative battery cable.

camshaft timing mark at 12 o"clock, align cam shaft timing mark to ( v ) cut on top of back timing cover, crank shaft gear align 12 o'clock key way up, there will be a mark on the outer edge of gear, on housing at 12 o'clock there will be the timing mark align that mark to crank gear , install belt and your done.Good luck.

I hope help you with this (remember rated this help) Good luck.

there is a special tool to hold gears in correct place on some of these models, but you can hold one cam at a time with a spanner then feed belt on exhaust cam then inlet cam gear
get someone to hold gears in place while you feed belt on.
the inlet cam is more prone to turn off mark more than exhaust.
if you have tensioner that needs retaining pin in when installing
you fit belt while aligning timming marks
fit tensioner as last spot to feed belt on with retaining pin in adjuster
get correct tension on belt by turning water pump so that you can flex (turn) belt 90 degrees only just while using finger and thumb
tighten water pump check flex
check all timing marks are correct
remove retaining pin from auto tensioner
turn motor over a couple of turns by hand observing tensioner arrow should hover around V mark and that all timing marks align up again(after one complete turn)
