EVO IX wont start after cosworth 272 cam install..HELP!!

[satmo2002]

I’m going to get to the point. I was installing cosworth 272 cams in my EVO IX MR yesterday planning on getting it tuned afterwards. But after the install the car wouldn’t start. I checked the timing on the cam pulley and it was and still is a TDC, also the timing marks on the cam gears. When I did start the car I heard a “popping” sound coming from the engine so I decided to go back to stock cams and go to the shop (maybe I was messing something up with the new cams). I put in the stock cams and to my amaze still no start. But I didn’t get no “popping” sound it just sounds like its not turning over. Ive checked EVOm and haven’t found anything that could help me out. When I did the cam install on both cosworth 272 and stock is I made sure the cam gears where lined up and the tick mark was at the “T” on the cam pulley. Then I zip ties the timing belt to the cam gears so I wouldn’t lose my timing (I’m sure it didn’t). I took out the exhaust cam first and bleed the lifters (I heard you do and you don’t have to, but I did). I reinstalled the exhaust cam and tightened everything back up from the torque specs I seen on Evo MOTO. I did the same with the intake cam also. Any tips or am I missing something. Thanks for the help guys.

did you line up the cam angle sensor properly?

[satmo2002]

I didnt remove the entire cam angle sensor. But I made sure the trigger was in a 45% angle when I installed the exhaust cam.

[satmo2002]

I heard some issues with the mini battery not starting in the winter time but I have started it when it was cold before I "tried" to do the cam install. But not that I have the stock cams in I hear back fire from the exhaust but no start. Is there something Im missing or should try. Im will to do almost anything (to the car ofcourse), besides ripping the engine apart (Im not that good and it shouldnt get that far).

Did you unhook any other sensors to clear room..I know when i did my head on my 2g we timed the car about 6 times before finally realizing that the maf was unplugged..

[satmo2002]

Yes, I unhooked the exhaust plug in the front to get to the the wires out of the way. but i plugged it back it. Im going to recheck all plugs. Is there a way to mess up timing even tho everthing lines up?

[stevolution]

Maybe bad wire somewhere...That's another problem i had on my 2g after installing some new parts the car just would run right..Again thought it was timing....Tried and tried and tried finally said fuck it, me and my dad swallowed our pride and trailer-ed it buschur's...Where in about an hour they told me that two of my injectors wires were bad...How this happened, God only knows...

[satmo2002]

I just did a compression test and its 0 psi in all valves. I pulled out plug wires, took out spark plugs. Disconnected cam sensor near the back. Held down go pedal and cranked for 4 to 6 seconds. Nothing. Question 1, did I do the test right? Question 2, if I did the test right what could be the problem? Question 3, what could be the problem...(hahaha). I talked to Jarod on the phone and he said im pretty much SOL, but im willing to try anything right in my power before I get a trailer and take it to a shop. (shop is closed today anyways)..

[b00stedtalon]

It's not timed right if you have 0 compression in all your cylinders assuming you did the test right. A compression test is simple, replace compression tester with spark plug. Take the timing belt cover off and check all your timing marks. Re-time it and pray it starts and that nothing got damaged? Hopefully you didn't bend any valves.

[satmo2002]

Ok, lets say I didnt bend a valve..(Im trying not to think that)..how could I re-do timing if all timing marks line it and the cam pulley is at TDC, would I have to take the whole front passenager side off and start from there? I was hoping I did the compression test right, but it was my first time. And it hurt like the girls says. (because it was 0 psi). I was told I had to take the fuel pump fuse out when I do the compression test. Is that true? I didnt know that and if it is I will do that test again.

I'm thinking that when you heard that "popping" noise when trying to start it you may have done something to the valves...hopefully not though...it may be time to find a trailer....Where about in NC are you?? Shoot Force-Fed Performance a PM, they are from the fayetteville area & may be able to help you out...

[satmo2002]

I will do that also, but im in fayetteville. Im hoping its not the valves either.

[b00stedtalon]

Wether the fuel pump was on or not, it would have not made a difference. Sounds like it may have jumped timing when you tried to start it that one time.

You can refer to this for timing belt help. http://bit.ly/9w44PS

Although, I would just take it to a shop if I were you before any more damage is done, if possible.

[xfactor evo]

Not sure, but don't you have to line up the crank pulley too? I that is true then you probably bent your valves

[stevolution]

Yes all pulleys must be lined up

[Liqquid]

so you've gone back and made sure all pulley's line up.. the cam gears with the valve cover mark and the crank mark is visible on the accessory pulley "just before' the mark on the cover... and at that time, the cam angle sensor has the large part sitting at 3-4 "o'clock" when viewed from the driver's side?

The rest of this just seems very unlikely

[satmo2002]

Yes, I went back and checked the crank pulleys timing marks and the cam gears timing marks. The are all point at TDC. The cam angle sensor is siting at 3-4 "o' clock.

[RedEvoVII]

You are sure that you mounted the Intake cam gear in the right position? I had also an customer who did the install by itself, and the reg pin of the intake cam was not inside the reg hole of the gear. Instead, it was actually in one of the Oil holes. ( i never thought that this would fit, but with enough force it WILL fit )
Then the cam is app 90 deg OFF ( only the cam, not the gear )
Check the cam by hand turning the crank without cam cover.
At TDC the intake Valves cyl. 4 should OPEN and the Exhaust should Close, but both will be not fully closed ( cam lobe is still not at min radius , Overlap in progress ).

[xfactor evo]

Well hopefully it isn't something big like that with bent valves and stuff

[Force-Fed Performance]

Hey man, give me a call or shoot me a PM if you need me to come by and check it tomorrow.

I havent read every single post here but sounds to me that you messed something up and bent your valves. Having every single cylinder stay 0 afterwards makes me also think you didnt do the test right. Where did you buy the cams from?
It IS possible that you received a bad set of cams where the dowel pin is machined wrong on the ends of the cams. I am not trying to cause a problem or a pissing match But about 3-4 years ago we discovered the infamous Cosworth cam dowel problem after an engine blew on us after a perfect install bending all the valves. We then went to install another set a couple weeks later and I happen to catch it again for a second time that the dowels were machined wrong in the cam ends. Not saying this is your problem. But we HAVE seen it before and heard of more cases but it has been years since anything. Its hard to say your problem when someone says "I did the install perfect and still no start after rechecking everything 3 times." Also the cam angle sensor being set in wrong will not cause the car not to start. Even if it is 180Degrees out it will still start and run/
