If the cat was doing anything, it would smell like rotten eggs.
If you have raw gas smell, use caution; you have a leak somewhere in your fuel delivery and you could see flames eventually.

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

SOURCE: how to set the timeing on 91 geo storm

The timing marks are located near the top of the crankshaft pulley on the plastic timing belt cover. There is a notch in the pulley to mark TDC (Top Dead Center)
Align the notch with the 0 mark on the plastic cover to set your base timing.
Ground the proper circuit on the ALDL connecter located under the dashboard somewhere under the steering wheel. Check the manual for the proper circuit to ground.
With the engine warm and the circuit grounded. Set the proper timing. Un-ground the circuit and you are done.

Ok 1990 geo storm 1,6 litre dohc replaced water pump replaced 3 valves replaced head gaskets replaced timing belt car wont start any ideas?


90 Storm, must be in Canada, 1,6 (the comma tells me this)
the storm is a:
The car is really an Isuzu Impulse minus some of that car's more expensive features.
my guess is you drove the this 4EX1 engine until the cam belt slipped. yes> if yes you bent valves.????????????
so does compression exceed 150psi on all 4 cylinders now?
we use the cylinder leak down test in all DOHC .
if not , back to the drawing board.
if yes, the we check spark next, then try test fuel.
when did the engine last run , last week,month , year,?
who did your valves, a real machine shop or kid down the street.
a read shop pressure tests the head ,and warp checks it and
then makes sure the valves are ready for long service.
are the head bolts at 58 ft/lbs
did you use sealant on the 3 cap caps, per the FSM book.
if not , top end oiling will fail. and cams wrecked.

the 1.6l DOHC has no HLA's
the lash on valves must be checked, and this is corrected with SHIMS.

a pro machine shop does the for you,did they:?
when rebuilding engines, its best to read the factory service manual first. FSM so you know the special steps just for this engine.
ISUZU engine it is.

1.6L Twin Camshaft Engine
  1. Disconnect the negative battery cable.
  2. Remove the cylinder head or valve cover.
  3. Position the No. 1 cylinder at TDC on its compression stroke.
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.
  1. 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.
  2. 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.
  3. 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.
  1. 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.
  2. When the adjustment is completed, install the cylinder head covers and connect the battery negative cable. Start the engine and check for leaks.

Does this car take a valve lash adjustment and what are the settings


Your car has hydraulic lifters. Hydraulic lifters just means that it uses engine oil to control the valve clearances using a bucket and shim arrangement.
Here's a generic image of what a hydraulic lifter can look like:25949035-hsh3lir2aljnaf1jzrgt1uh1-5-0.jpg

If the car makes a tapping sound at start up, this points to a problem in the camshaft area - including the hydraulic lifers/shims. Valve clearances are controlled by the lifters and shims. It could also be a worn camshaft - the lobes can become rounded.

Usually, there is no adjustment possible with most hydraulic lifters. Replacement (usually) means you have to remove the camshaft, though I am by no means certain about your particular model.

If you have the tools and ability, remove the rocker cover and have a look at things.

25949035-hsh3lir2aljnaf1jzrgt1uh1-5-1.jpg The image above shows a camshaft - the lobe is worn and rounded. When this happens valve clearance is excessive and may lead to a tapping noise. Engine efficiency is also affected.

The image below shows hydraulic lifters (example only..).
The lifter on the left has a 'dished' surface - wear caused by the camshaft or the lifter not being able to 'turn' in its bore.
25949035-hsh3lir2aljnaf1jzrgt1uh1-5-3.jpg The usual cause of this is (a) short trips where the engine hasn't had a chance to warm up properly and pump oil to the camshaft area (b) poor oil/infrequent oil changes (c) stuck lifter.

Before you spend money on parts or repairs, first try adding some oil flush to the engine to clear out carbon and 'sticky' deposits.


25949035-hsh3lir2aljnaf1jzrgt1uh1-5-10.jpg
... follow the instructions on the bottle...
Then change your engine oil and add something like a 'valve train additive' - this will try and quieten the tapping noise.
The (Ebay) link below will give you an idea of what additives are available (and so will your local car accessory shop).

Try the cheapest and easiest first. If that doesn't work .. unless you are confident that you can inspect, diagnose and replace parts .. give a mobile mechanic a call. Those guys are usually quite good.

I'm looking for the Toyota corrola 1.6 4AF engine valve clearance


will need a micrometer, valve clearance adjustment tool set for shimmed lifters,small magnetic arm, appropriate shim selecting charts (manufacturer will have this if you can get the nec. measurements).
Measure thickness of shims removed (using micrometer) and use this formula where T=Thickness of old shim; A=Valve clearance measured; N=Thickness of new shim required.
Intake valves: N = T + (A - 0.02 mm (0.008 in.)) Exh. valves: N = T + (A - 0.25 mm (0.010 in.))
Then you need to find shims as close as possible to the calculated values.
Valve clearances (cold) are as follows: Intake0.15 - 0.25 mm (0.006 - 0.010 in.) Exhaust0.20 - 0.30 mm (0.008 - 0.012 in.)
Note, if you are not familiar with precision measuring using a micrometer, this may be better left to a trained tech. These are high revving little power plants and you don't want a problem at 8K rpm.

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

How to adjust valve lash on a 1990 Geo Storm


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.

1993 mazda mx6 2.5 when should a valve adjustment be done little noise is that common 144,000 mles .


the valve lifters should be hydraulic and not adjustable on that engine, either you have a clogged oil feed to them, in which case wynns hydraulic lifter treatment will cure it after a few days, or the shims are worn and replacement means using a micrometer or vernier gauge to measure each shim against the specified clearance and then fitting individual bucket shims to each valve to correct the wear, but try wynn's first, its cheap and works well for sticky lifters.

If the 2.5 has VVT (variable valve timing) it may be this unit thats making the noise, not the valves...

Need to know how to adjust valves, or a print-out of adjustment procedure and tools reguired. 1989 toyota gt-s corolla 1600 16 valve 4a-ge cal engine


This engine utilizes shims to set proper clearances, you will need a micrometer, valve clearance adjustment tool set for shimmed lifters,small magnetic arm, appropriate shim selecting charts (manufacturer will have this if you can get the nec. measurements).
Measure thickness of shims removed (using micrometer) and use this formula where T=Thickness of old shim; A=Valve clearance measured; N=Thickness of new shim required.
Intake valves:   N = T + (A - 0.02 mm (0.008 in.)) Exh. valves:     N = T + (A - 0.25 mm (0.010 in.))
Then you need to find shims as close as possible to the calculated values.
Valve clearances (cold) are as follows: Intake 0.15 - 0.25 mm (0.006 - 0.010 in.) Exhaust 0.20 - 0.30 mm (0.008 - 0.012 in.)

Lifter knocking on 1999 Nissan Frontier


red: there were two engines used in the1999 frontier.
The VG30 (V-6 )and the KA24DE (4- CYL)
If you have a V-6, there is no adjustment you can make on the valve clearances. They are hydraulic and self adjust. If they are noisy, you might try changing the oil and filter and using an oil additive designed for addressing high mileage motors with noisy lifters. Marvel Mystery oil actually works, but follow the instructions. MORE IS NOT BETTER!
The 4 Cly engine does not have adjustable valve clearances from the stand point of using a few wrenches, one to adjust and the other to lock the adjuster when the clearance is correct.
These valve clearances are set using shims which are "metal discs about the size of a quarter. They come in various thicknesses and based on the measurement between the base of the cam when the highest point of the lobe is facing the 12:00 position, you place a feeler gauge between the base of the cam and the top of the shim.
If it is too loose or too tight, you use your feeler gauges to find out what it would take to make a zero clearance situation. From there, you remove the shim, measure it. Based on your findings during your initial measurements, you can calculate whether you need to use a thicker or thinner shim.
So to answer your question: unless you have a lifter confused with some other component, there is no means of torquing a lifter down on either series engine which came in that truck.
Please let me know if I can help you further. There must be some reason why you have asked this question......?
