There's a kit from Comp Cam you need to limit the phaser travel after you swap a cam.

Yeah, I know it looses something in the translation...

So after testing the compression (which was only
Around 30psi) and taking the blocks off, I've come to find out that I didn't install a Limiter...which eventually lead to a few of the pushrods being bent..and possible damage that is still to be determined. I got in touch with Josh over at GPI, and I have a limiter and pushrods on the way....hopefully that should solve the problem! Can't believe I missed the most important part...

Oh man, so sorry to hear that! I hope the damage is minimal, but the push rods bend because the valves are hitting the pistons, right? It's not a failure just another learning experience. We've ALL had them.

i hope the valve didn't hit the piston or you have to do a lot of work. even thought the idle is not raised the car should start .since you get the pushroad bended it make me think the cam wasn't in phase correclty and when you got the oil inside the lifter the valves touched the piston. that's just my idea. i'm more than happy being wrong

I know! I'm just upset that i didn't pay attention to the smallest yet most important piece I was missing. I let excitement get the best of me and had to pay for it in the end. I am happy to say the damage is minute. None of the lifters were ruined, and the pistons were fine. I just bent the valve where the bent pushrod was at. Back to the shop they go!

(BTW, Thank you for all of the help you've contributed when it comes to this situation also! I greatly appreciate it and would have been completely lost if you wouldn't have mentioned the Phaser Limiter!

I think you may be correct. The pistons were fine (thankfully). I just had to send the heads off because one of the valves were bent where the pushrod was bent. Hopefully i should have it all back together by Saturday with an update! *Fingers Crossed*

Glad to hear no real damage done

Now do we need to talk valves springs?

WOW

Haha! Thanks bro! And i took the smart road and upgraded those so

sdynak · 05-03-2016, 07:47 PM

So are you saying without the limiter the cam was able to turn out of phase to where it allowed the valves to open when the pistons were at TDC? Glad you found it with minimal damage and sometimes it takes extra to learn but you will never do that again

.. Be running soon!

trw427ss · 05-05-2016, 03:18 PM

Which valves did you bend Intake or Exhaust?

Yes, the phaser allows about 50 to 60 degrees of timing movement and the limiter resricts it to about 20 degrees. Check out this video:
