Question about 1990 Geo Storm
Posted by Anonymous on
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.
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

the fuel pump is located inside the fuel tank. drop the fuel tank and unscrew the top of the fuel pump and replace the fuel pump

your timing may be off because of the valve timing. have you seen this done before or you just trying your luck. i really dont know but are all of your sensors the same? is the firing order the same?
