Please give me a call on monday and we will get you a single intake cam.

+1 Speak about customer Service..

I've never seen a thread blow up like this has for no reason at all... this engine has never run. it wasnt a faulty camshaft it wasn't a mivec engine. It is simply tightning down the cam caps with the cam rotated incorrectly. like i said in my first post its a common problem on longer camshafts and it does happen. Heck As many camshafts as i handle i've actually done this same thing with a 2JZ cams before.

Greg, for the other forum members, could you please explain the correct rotation the cam should be in for a cam install. So that everyone following this thread knows how to avoid this accident etc

Greg - Great of you to come in and comment and provide support

. Can you explain what has changed with the 'new" MIVEC cams to address the earlier failures ? Thanks !

Yeah... People installing cams with the engine running all the time!

There is no "rotation" going on at all. You make sure the dowel rod sticking straight up and the caps should not be binding while being "walked" down.

its vital that on initial start up the car fire up instantly and you rev to 1800-2000 to ensure oiling.

Oh brother... do you even know what your talking about?

I have an evo 8 long block engine i'm building this week. i will snap a few pictures of how we install cams. for one we do not use TDC on the crank when installing the cams do to the rotation of the cam. i will post something up in our section on friday.
