I only tighten things to factory spec when they're critical, such as head bolts. The poms tend to tighten absolutely everything to factory specs, up to & including wheel nuts A good hand nip up is usually all those rocker bolts need...
Having said that Dras, If it were me, I'd nip up the rocker gaskets a bit tighter. If that stems the flow of burnt oil a little bit, then we'll know the spark plug seals (little rubber rings on the inside of the rocker cover where the spark plugs go through) are shot.
If not, then we need look further.
That hurts a little bit inside Ben - torque settings are there to be followed by the letter
Give it time, soon you'll be one of us, very 'gdaymate'owyagoin' about everything
f**k off, if any mechanic actually went by the book on every torque setting, let alone 40% of them, your labour cost would be twice as large as it is now.
Most mechanics cant even find the god dam manual let alone know how to use one.
As Ben says to is only the crucial ones that are followed (which means the ones inside the engine lol).
CHRISTIANITY: The belief that a cosmic Jewish Zombie who was his own father can make you live forever if you symbolically eat his flesh and telepathically tell him you accept him as your master, so he can remove an evil force from your soul that is present in humanity because a rib-woman was convinced by a talking snake to eat from a magical tree...
Most mechanics just have "a feel for it" and know how many turns from handtight they need to tighten something to the proper torque .. but if you're not some uber experienced mechanic, then what's the prob with doing what it says in the workshop manuals?
unless you've done it a million times, you're likely gonna be going off the manual anyways & it's only gonna take like 5 mins on top of the total job..
