evo IX wont start
Dont know about the nine but on a eight you can install two exhaust cams the exhaust cam on the intake side would have to be 180 degrees out. There was a guy once on here you had a slow evo 8 with cams he took off the valve cover and to his amazement the shop where he bought and had hims cams installed put in tow exhaust cams.

After thinking some more about this issue, I believe it would be possible to install the mivec cam incorrectly. There are two oil passages in cam gear that MAY accept the dowl pin that locates the cam in the gear correctly. If this were to happen, the cam would be installed 90 degrees advanced or retarded. This would cause lack of compression or possibly bent valves.
The easy way to check if this is the issue would be to put the motor at TDC and take a look at the lobes on the cams for the number 1 cylinder. They should be either facing each other or facing away from each other. If the exhaust cam lobe is facing the front or back of the car and the intake cam lobes are facing up or down, then the locating dowel is in one of the oil passeges in the cam gear.

if what you are saying is true. that would throw all 3 timing mark off. also if it's not the the dead on the pin the cam gear wouldn't be flush. cause the oil passage is not that deep comparing to the acutall hole the camshaft pin go through.
The timing marks would be correct on the cam gears and crank, but the cam would be rotated in the wrong position.
The oil passage theory is just that.. I am trying to think of possibilities. I said it MAY go in not that it would... To check for sure, pop the valve cover off and set the motor at TDC and check the number 1 lobes as described in my last post.
If everything looks good, I would go back to my initial theory of the lifters being the issue.

why don't you test each cylinder one by one. take out the spark plugs, turn the engine by hand until the piston is at TDC on compression stroke then use compress air and blow it into the spark plug hole, then you listen for the leak. If it from your intake then your intake valve is bent or not close. listen to the exhaust, dipstick tube and make sure your radiator cap is off.
They wont be exactly facing towards or away.... You are not looking for a little off, you are looking for a LOT off... If the intake lobes are down enough to be pushing the valves open at TDC then its an issue...
your'e right. it's fixed. the cams were off and cams gear on the intake due hte stupid mivec cams gear. thank you so much. you're the best and you know your **** 9sec240

Also big thanks everyone who contribute to this ****. thanks
