Ok, no one has asked the ? so I will.
what is the, where is the valve train wear accruing.
what to look for?.
Why do these engines have a noisy valve train?.
what should be replaced.
cam, lifters, p-rods, rocker or valve?.
actually starting a new thread for all to see.

Thanks fixer, never heard of that, but never worked with solid lifters or roller rockers either.
Our TB42 rockers work the same as roller rockers. We just dont have the roller on the tip to roll over the valve tip.

Hello, new to the forum. my name is nick and im from warragul in victoria! (will go and do a proper introduction with pictures and what not when i get home )
i Have a mav, dual fuel and once it gets warm, i.e driving for 15 or so minutes, it produces a spasmodic sort of miss, "pops" and the revs drop on the tacho. its not enough to lose speed but is enough to scare the shite out of me. i can hear the tappets, quite loud. would this be causing the vehicle to miss?
Thanks,
Nick

Dont worry, you won't get slammed here. I must admit, I was always under the impression that adjustment should be done whilst the engine was warm. So not sure if there are cold settings. Hopefully if someone has done it, they may be able to help.

I have this from a Haynes manual:
TB42 valve clearance:
COLD:
Intake 0.20(mm), 0.008(inch).
Exhaust 0.20(mm), 0.008(inch).
HOT:
Intake 0.38(mm), 0.015(inch).
Exhaust 0.38(mm), 0.015(inch).
Note: "cold" is 20 degrees C.
I had a mate help me adjust mine last year. About a 40 minute drive to his place so we set it for the hot adjustment. It made a noticeable difference with power and economy.
