what engine code ? Z16XEP and XE1 don't have sprung lifters that fill with oil ,they are more of a cup/shim
Common issue is the baffles in the intake manifold become un-glued ,this results in a NOCK sound (can sound terminal )
I've done this job ,wasn't convinced that the baffle being loose would make such a racket
so I ordered the shimmed lifters (set of 8 exhaust)
spent a few hours cleaning, re-sealing the intake
it was cured
£100 worth of lifter shims came , and are having a "rest" in the parts hoard
