Yes im sorry the picture doesnt show it.

 

This is from my car which is also a 2.4. The dowel being at 3 o'clock is correct at TDC. Do you still have the keyway on your crankshaft?

 

It cranks like an engine with no spark plugs in it. Makes me think that the head gasket isn't sealing right. Has your tune been scaled for your injectors? This is weird.

 

Did u hear it without the rockers in tho? And head torqued

 

Ya scaled for my injectors.

 

Ive also looked at other motors cams at tdc timed and its the same cam postion as mine....

 

First person to figure this out 100$ lol no joke

 

Lets start with what we know and have verified thus far:

1. The crankshaft has the key way installed so that the crank gear can't spin freely on the crank. (right?)
2. Timing is dead on.
3. Injectors are spraying fuel
4. Spark plugs are firing and gapped correctly
5. Compression tester (Which has been checked and has a schrader valve/check valve installed) reads 0 psi across all 4 cylinders and is a known working compression tester?
6. Tune is setup for 2.4LR motor and injectors are scaled
7. If injectors are high impedance, resistor pack has been removed

Sensors to be checked:
-Exhaust CAS
-Intake CAS
-Crank angle sensor
-MAP sensor
- Front O2 sensor
-If running speed density, unplug the MAF.

That's all i got for now. Hopefully this isn't some strange issue like the cylinders being ridiculously out of round or a bent cam.

 

Guys, if you check the video on post88. Assuming the start point is that 1st cylinder piston is at tdc. When the cylinder 1 piston is coming to tdc next time, the exhaust should close and intake should start opening (overlap), but it is not.. Or maybe I am thinking it all the way wrong LOL

I don't have a mivec and the timing marks looks good on post 1, so wrong timing shouldn't be possible. Or can you somehow install the cam and mivec gear off?

 

The intake cam should have a dowel pin on the end of it. There should be a provision in the cam gear itself to allow the dowel pin to line up with the cam gear so that the direction of the cam is correct.

 

Did you remove the MiVec cam gear from the cam? And how did you prime the motor before start up?

 

Yes to do the mod. And primed by cranking the motor over. My mivec gear never got lumped up all the way.

 

you are SURE that the Mivec Cam Gear was installed correctly...

It is POSSIBLE that the cam dowel pin intake cam was going into one of the oil holes in the Mivec cam gear...instead the dowel pin hole....

Then the intake cam runs 90 degrees of cw or ccw.....

 

so i couldve inserted this back into the casing 90° off? Basicslly one space off? Most likely the issue. If anyone has a picture of thwre inrake cam when 1 is at tdc this will resolve this being the issue.

 

Would make sense why the valves r fine. The cam is still in time just off.. so how do i know how to lime everythinf up inside the case? Like whwre the cam dowel position should be?
