Engine rockers making ticking noise

Asked by Mar 12, 2016 at 09:01 PM about the 1993 Mazda B-Series Pickup 2 Dr B2600i 4WD Extended Cab SB

Question type: Maintenance & Repair

I have a 1993 Mazda B2600 with the stock 2.6L 4 Cylinder in it. The
rockers are making a ticking noise like they are depressurized but when I
check the oil level and all of the seals they are fine. The rockers
themselves just got replace 1,000 miles ago so I know they're good.
Previously when this nose would happen if I added oil then it would go
away, but now my oil level is full and its still ticking. Does anyone know why
they are making this noise and how to fix it?

If they have been replaced then the only other thing it can be is lack of oil pressure to the top end of the engine, so you could have a bad oil pump or the oil passages are plugged that feed the rocker arms and the lifters.
