Question 3.0 lifter noise

On this 2000 ranger 3.0, I have already replaced the heads with rebuilt ones and replaced the lifters, cam syncronizer and water pump. My 1st problem is that I have seen conflicting info about TDC so I am not sure if my cam position sensor is lined up properly.My haynes manual states TDC on the harmonic lined up at the crank sensor, with #1 piston on compression stroke. I used the alignment tool that came with the sensor and the cam syncronizer . My 2nd problem is the lifters sound like they are not pumping up with oil. I coated them in oil during the rebuild. It sounds as if the drivers side is worse than the passenger side. It has great oil pressure. I am wondering if I might have a blockage and if there is an easy way of checking for it without a complete teardown.

Did you prime the motor?

yes . I disconnected the coil pack with the plugs out and the fuel pump disabled. Then I cranked it until it showed oil pressure.

Re: 3.0 lifter noise

There's a port in the head gasket that allows oil to flow to the rocker arms but not the lifters. See what the clearances are when you take the valve covers back off. Did you mark the push rods and put them back in their original location? Or is it the overhead OHC engine?

Re: 3.0 lifter noise

This engine is the flex fuel Overhead valve engine , not overhead cam engine.The machine shop mixed the parts during the machine work. They said it would not matter since I was putting new lifters in. I measured the lengths of most of them and the differences in lengths wasn't over .009 in. . Soon , I will pull off the upper plenum and valve covers and check the clearances if there is no other solution. I am concerned that one head did have .023 milled off from it. Is it possible that this could cause my lifter noise problem?

Re: 3.0 lifter noise

No. Why did you replace the lifters ? I'm sure that engine has a roller cam. Putting new lifters on an old cam is a very bad idea. It WILL make noise but eventually
go away, maybe. The lifters will self adjust as much as 1/8 to 3/16 on an inch. You probably don't have lifter noise but cam noise.
