Re: dual pattern cams
Really basic question here....."It is a Hydralic cam??".
Now if it keeps bending the pushrods and the lifters are Hydralic.....I'd check the push rod length. If that is OK....check for valve spring coil binding. Crane has a good explanation on their site on the correct, and more importantly, the easy way to check this. Crane also talks on one of its sites...don't remember which one about coil bind. Bring the adjusted rocker to full lift and measure the distance between the coils on the valve springs.
The dual pattern shouldn't make any difference.
I adjust mine with the engine off. Spin the push rod till it doesn't turn and add 1/3-1/2 turn. I have never had a problem.
