Not getting any oil in the top of my engine.  Its a 3 litre Esseex V6 (D port) and has great oil pressure, I have rebuilt it and assumed the main bearings went in upside down or the thrust washers back to front.  A bottom end strip down reveals all went together perfectly, and I can push a wire up through all the oil holes in the crank and galleries.  so now I'm buggered.  Anyone got any ideas what to check next?

Do you change the cam bearings?, was the block chemical cleaned?? the bearings need replacing if the block was in the hot dip. My take is that the oil pump feeds the crank then the cam which feeds the rocker gear
hope it helps O

No dipping no change of cam bearings.  I had the cam re-ground and the lifters refaced

I assume the top end is fed oil via pushrods and assuming there is good oil pressure up to the lifters?If so you haven't put in solid pushrods, or something wrong with lifters since they have been resurfaced not allowing oil through??

The V6 is a solid lifter motor and just the top face has been machined .  Pushrods are the original items cleaned out (hollow).  It has run for probably 3 hours and I only noticed something wrong when it started to squeak loudly from the tappets at number 4 cylinder.  The inside of the rocker cover is bone dry and the rockers are so dry they have a powdery rust finish on them

Is the sump still on?? take the dizzy out, as the oil pump drive shaft is a hex, use a socket and attach it to the drill, and prime the oil system. see if it is pumping to the cam and the lifters. O

Sump is off but I can use a bucket of oil at the pickup.  I'm thinking that I'll have to reassemble the bottom end though as I cannot see aything wrong in there.  Do you happen to know where the oil enters and exits up the topend?

Oil comes in at side of lifter body up the top of lifter then through the pushrod and pools in the middle of each rocker and lubricates its pivots. Return oil goes back down the cyl head drain holes back to the sump.
