We tried changing out the sensors but mine are fine.
Should be getting new Cam sprockets this week and have them installed Wed. if all goes as planned.
Hope this is it.
How is yours so far ?
i ve got the same noise in mine, tried 2 sets of sprockets already, replaced all the lifters, and changed the guides. And i ended up bringing it into another machine shop, the guy over there told me those are piston slaps. I m not to sure about having piston slap on my newly built engine but the guy told me they are "Healthy" slaps and would go away after the engine is warmed, whichs true.
He thinks the problem are from the clearance on alunimum pistons where they have 4thou when sitting cold and expand to 1thou after they got heat up. Thats when the noise got eliminated.
Ed if you disconected the Cam sensors did the noise go away? Mine did as soon as the sensors were disconected. If it was piston slap how would sensors account for that?
Also my noise was only there after the car was warm, at low idle and the oil pressure was at the low point. As soon as we increased the rev's and built oil pressure the noise was gone.
