How to change lifter shims on a 1990 geo storm


old post. (no FSM book, or can log in to alldata.com>?
its the 1.6L twin cam, only IT has shims.


answered; with no photos, get the book, or login.
steps: (quote)
The notch on the crankshaft pulley should align with the 0 degrees mark on the timing gear case. Make sure the rocker arms on the No. 1 cylinder are loose and the rockers on the No. 4 cylinder are tight. If not, turn the crankshaft one complete revolution and align the marks again.

Using a feeler gauge, measure the clearance between the cam lobe and the selective shim on the intake and exhaust valves on the No. 1 cylinder, then the intake valves on the No. 2 cylinder and the exhaust valves on the No. 3 cylinder. Note readings.

Rotate the crankshaft 360 degrees. Using a feeler gauge, measure the clearance between the cam lobe and the selective shim on the intake and exhaust valves on the No. 4 cylinder, then the intake valves on the No. 3 cylinder and the exhaust valves on the No. 2 cylinder. Note readings.

The valve clearance obtained on the exhaust valves should be between 0.008-0.012 in. (0.20-0.30mm). If not, replace the selective shim by turning the camshaft lobe downward and installing tool J-38413-2 or J-38413-3 (valve lash spring spacer) between the camshaft journal and the cam lobe next to the selective shim. Turn cam lobe upward and remove the selective shim. Install new shim using the selective shim chart.

The rear camshaft bearing caps must be removed to remove the selective shim.

The valve clearance obtained on the intake valves should be between 0.004-0.008 in. (0.10-0.20mm). If not, replace the selective shim by turning the camshaft lobe downward and installing tool J-38413-2 or J-38413-3 between the camshaft journal and the cam lobe next to the selective shim. Turn cam lobe upward and remove the selective shim. Install new shim using the selective shim chart.

When the adjustment is completed, install the cylinder head covers and connect the battery negative cable. Start the engine and check for leaks.
end quote.

the real question is.
where do i get shims from a dead car company if in USA? now that be the big question.

All of the sudden the engine is making a weird noise. Friend says it may be the harmonic balance or the crank is bent.


the harmonic balancer can come apart, but the crank bent? i dont think so. I would have a shop check it out, we could guess all day.

I changed the harmonic balancer and now it is terribly out of time. Didn't touch any timing belts, distributor or the like. Any advice?


There may be a magnet on the harmonic balancer for the crankshaft sensor,

The cam and crank sensor call for spark to the plugs..

Some cars you need a Harmonic Balancer Installer Adapter,
to make sure everything is lined up and gaped..

Check the crankshaft sensor for damage from inproper install, also check the wires going to sensor,, some times the harmonic balancer are such a Pain!! to come off the sensor or wires get damage in the battle.

Yes a harmanic balancer from tha corolla is the same thing. I had to do the same thing with my 95 geo. It works out to be a lot cheaper buying for a toyota than a geo.
