Did delete Lh6 (Solved) Hey everyone
Looking for some help I am new to this forum. I have a 2006 envoy with a Lh6. I have done a complete rebuild and a did delete. First start up was great. The after a worm up I started to get a lifter tap. Have all new parts in engine. Complete rebuild. Oil pressure at idle worm is about 38 psi. Can't figure out why lifters start tapping. In you need more info let me know thanks for any help.

Yes I did then spun the engine over and rechecked. The thing is on cold start it is fine when it gets to operating temp the lifter seem to lose oil pressure. But the oil pressure is at 38 psi at idle.

I have a slight noise when warm but does not sound like a lifter.
Yours definitely a lifter noise?
