z20net tappets

[beat275]

is there a how to or does anyone know how to tighten or replace the tappets on the z20net engine?

[rushy]

Not being funny mate but why? Are you getting a noise?

[beat275]

yeah a tapping noise lol

[rushy]

Is it constant or just at start up, the hydraulic lifters can drain back a little and make a noise on start up and the chain can make a similar noise as well.

[beat275]

hmm could be the chain. but costly

[rushy]

Its very rare for the chain to fail on the NET mate, but on a high miler it could start making a noise.

[beat275]

any suggestions?

i S THE ENGINE DUE AN OIL CHANGE?...OIL L EVEL OK?..CORRECT GRADE?

[beat275]

Yeah but it has done 80k miles

Mines at 66k and quiet,I use 5/30,changed every 6 months, but I believe others use 10/40 at higher miles..
