Its an Isuzu engine.
there are 3 engines.
4XE1, SOHC 1.6L (base)12valves
4XE1, DOHC , 1.6L same as above but now with 16valves.
4XE1, DOHC, 1.8L bends valves if belt snaps...
note the bad idea of ISUZU calling all 3 engine same name.
a horrid idea.
which one? the second was in USA and Canada only.
the second one was offered as the GSI. is yours that?

so I will attempt to guess for you, its the base engine.
(odds of coin toss)
toss #2, USA, SOHC
guess 3: did a new belt and want to do lash next. Cam belt>
No job stated so i guess 3 times.
Just lash.
SOHC 1.6L only (FSM book quote)
Check the valve lash between the rocker arm and valve stem on both the intake and exhaust valves on the number 1 cylinder, the intake valve(s) on the number 2 cylinder and the exhaust valve on the number 3 cylinder. If the valve lash on the intake valves is not 0.006 in. (0.15mm), adjust the valve lash. If the valve lash on the exhaust valve is not 0.010 in. (0.25mm), adjust the valve lash.

1.6L twin cam has shims.
1.8L has HLA , no lash to set.

HLA= Hydraulic Lash adjusters.

I posted this before, search for it. Im only doing 1 engine.

SOURCE: 1992 Geo Storm having problems.

you may have turned too many rmps and warped a piston which would cause the piston to actualy hit your valve, or while turning too many rpms you may have caused the valve to "float" which would mess it up

Valve lash adjustment 1990 geo storm


it's an Isuzu engine, Manuel. so....
what makes you think there are solid lifters?
which engine option, that he first question, not stated.
1.6L or 1.8L
the 1.6L comes SOHC and DOHC version, so...?????
so many posts. on so many cars, why not log in to alldata.com
and use that for facts.
ill now quote stormowners.com

ISUZU changed with the wind.

The first generation of the 4XE1 DOHC engine was introduced in 1987 (1989 USDM), with hydraulic lifters, and rated at 135 PS JDM and 125 HP USDM. The second generation 4XE1 DOHC engine was introduced with the 1989 Geo Storm and 1990 Isuzu sister cars, with solid lifters, and rated at 140 PS JDM and 130 HP USDM.
The later 4XF1 engine went back to hydraulic lifters.


so again, what engine.
cant work on engines , not knowing what is there.
HERE IS THE rumor for 1.8L
http://www.fixya.com/cars/t12866696-lifter_gap

id not use rumors, on the internet, but fsm quotes work sometimes.
why not login to alldata.com and look.?

rumor 2
http://www.fixya.com/cars/t5549390-valve_clearance

all that , by using SEARCH.
id not use that, id read the book.

odd but good to know fact on Isuzu engines.
The fact is that the 4XE1 SOHC and 4XE1 DOHC are not sister engines,
so how many cams, , does your car have.?
vin 5 or vin 6?

Timing marks on 1.6 dual over head cam


the geo storm, 1.6 DOHC
the FSM cover it, so does alldata.com
hint 2, its an Isuzu engine.
its really (makes information easier to find )
Isuzu:
4XE1-UW a DOHC 16-valve engine with 130 hp (97 kW)
he DOHC engine was used in the 1990-1991 Isuzu Impulse XS, in the 1990-1991 Isuzu Stylus XS, in the 1990-1991 Geo Storm GSi, and the M100 Lotus Elan.
all that off the wiki,,
all cars rare here.....

1st google hit
http://www.robietherobot.com/storm/torquespecs.htm

This engine is interference type
so when timed, with a new belt
roll engine by hand, with spark plugs out.? do pistons hit valves.
yes, stop, the cam is timed wrong.
no, do a compression test on #1, if pass, do all 4. 150psi min.w.o.t.
wide open throttle
a better test, is a leak down test. x4. by hand.
these acts of kindness to the engine, saves most engines.

if the leak down fails, the timing is wrong, or the valves are already
bent..
dont use a fleabay china belt, bet a GATES belt. (they last)
setting the tension is very important to a full life .

Does a 1992 geo storm have an interfierance engine


If the timing belt broke, expect to replace some of the valves. It does not have a zero interference motor.

Timing belt broke


The Storm does NOT have an interference engine. If the belt broke, replace it and be on your way.
