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.



quote.
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.
end fsm quote.

see those 2 marks, and crank must be at TDC. mark first.

2000 Isuzu rodeo , no compression, drivers side


Cam timing not correct on that bank. Veryify cam timing. Not sure if the engine is a "zero clearance" engine but, if so, the cam timing error may have bent some valves! Oh nooooo!

Will a broken timing chain on a 2000 Lincoln ls mess up the motor


Yes, normally what happen is it throw out the valve timing. That is, one or two piston could be effected here with its related intake and exhaust valves. What could happen, broken piston tops, bent valves or broken valves.


Since, the 2000 Lincoln has a 4.6 litre V8 engine it will double over head cams. This mean each side of the engine on this V8 has it own camshaft. Also, Ford could have installed a cam brake, that is if the timing is lost, it will stop all valves in both heads to a close position. I hope so, some 4 cylinder have this option.



If the engine doesn't have a camshaft brake then major overhaul. It would be easier to buy an rebuilt factory engine to install. A good engine remanufacture that rebuild engine for Ford, Chevy, Dodge, and other auto manufactures would be you best bet. In other words, they rebuild those engines the way Ford wants them to be rebuilt. Best of luck. GB...stewbison

Valve Clearance Valve clearance is there to allow the valves to cool in between combustion events (spark), and to make sure the valve closes properly and contains the combustion explosion. You need to cool the valves a little bit, the exhaust valve moreso than the inlet, as it's what sees the most heat as spent burnt gases go past it into the exhaust port. Run too little clearance and you'll cause the valve to "weld" a little bit to its' seat every time it closes, and then take seat metal off again when it opens. Do this enough times and you burn out the valve seat and need the head reconditioned. However, by running less clearance, the valve stays open for that little but longer, and you get more air in and out of the motor, and make more power. Run too much clearance and your motor just sounds like a diesel and loses power and tappet rattle annoys you while you're driving, so it's better to err on the side of caution.
The stock valve clearance (0.008" inlet / 0.012" exhaust, warm) is pretty good for any of the cams I've listed above, they're well-sized street cams, not really wild top heavy race cams that require super high compression to work, so don't be afraid to close the valves up a bit from the suggestions of the cam grinder, which will usually say between 0.010" and 0.014". There are a few ways to set your valve clearances:
Yellow Book Method This is from the factory 3K/4K/5K engine manual, aka The Yellow Books. It's the quick and lazy method.
Set engine to #1 TDC. Crank pulley timing mark should be on 0, distributor rotor should be pointing towards spark plug 1 or 2. Set tappets (counting from the front) 1, 2, 3 and 5. Rotate engine 360 degrees, crank pulley to 0 again, distributor rotor turned 180 degrees. Set tappets 4, 6, 7 and 8.
Nine Method I've never really gotten into doing this, takes too much time and maths for my liking :P Rotate the engine through its' range of movement, as one valve is "on the rock" of its' max lift, subtract the valve number from 9 and that's the tappet you should be setting. For example, if #8 valve is open, set clearance on valve #1. If valve #7 is open, set clearance on #2. And so on.
Stewart uses this method, and rotates the camshaft through its entire base circle and sets the clearance at the highest point. Which is a pretty good idea, as it compensates for the possibility that the base circle has been ground unevenly, and allows you to run the proper valve clearance that you want to run, instead of something that may be a few thou larger in reality.

Intermittent tappet noise


Have they heard the noise or just you? Not hearing the click myself, it is quite possible that the exhaust manifold gasket has a small leak due to improper torqueing, crack, defect, or warp. I would sound mechanical but is actually air and would be intermittent at the early stages. Just to make sure, get a flash light and mirror and examine the exhaust manifold assemble looking for grey or black powder. It is a long shot but could be the issue, as could be a flat cam lobe, sticking valve from a bent or damaged guide, or other unforeseen abnormal conditions such a crack in a bucket.

You could try a super oil and see if it does not go away in a week. I have had them fix issues like this as well.

2000 excursion misfire on cyl 4. traded plug,


Remove the plug and check the compression for that cylinder it should be between 120 psi and 150 psi, if it is low it is a mechanical issue (bad valve or worn piston rings). If commpression is low remove the valve cover and turn over the motor confirming that both valves for that cylinder are opening to there correct travel or height if not it is a faulty hydraulic lifter or worn cam. Also check the valve lash clearance the clearance is usually .012" for the exhaust valve and .008" for the intake valve to check the lash turn the motor over until the valve shuts completely for each valve, then use a feeler gauge go no go procedure. Has the wire been replaced for the plug? If this motor has coil on plug type disregard plug wire question.
