I did 2 VVT builds this year ,2 weeks(11/15/17) ago we tore down one of the VVT builds that used the delete kit, and the front cam bearing is grooved at the back edge where the adaptor rides on the bearing
, car had 40 runs and roughly 3500 mile on the build. we pulled it just to check to see how the VVT delete was holding up.

now the engine owner is thinking of taking a Non VVT cam core , turning down the front journal, and making a "cap" (his words) to place over the front of the cam......My opinion is it's not worth the cost for one unit.
