Question :?:
How many people actually tighten the sump plug/oil drain bolt to 21 N-m. Sounds quite high to me. I don't.

Ehhh. Me? I think? Sounds needlessly high. Especially when you think what happens if that bolt goes byebye.

i think my spark plugs (25mn) is excessively tight, so i do them about 12, thats one thread i really dont want to be stripping.

oil sump goes on hand tight, + a teeny bit more.

Especially with the Sv not having a seperate sump pan. :lol:

sdusk , you are right about the bolts elasticity and wot not :lol: but the case of the sump plug shows damage can be caused if we get too obsessed with the torque figures in the manual/torque wrences. I use to be that way but now but no more.

I do mine more or less the same as warren. Hand tight and a quarter to half a turn. I do though put a blob of silicon sealant(outside) as belts and braces.


Cheers

That's not correct... The Halfords ones, or at least the 3/8 ones, are reversble, just not conveniently- you need to remove the head and put it through from the other side.

ive read that your not supposed to use a torque wrench for removal of bolts, only for tightening.

not sure how true this is though, and if it is, why give an option of a reversable head ?

Northwind, I hope the 1/2" Halford wrench is as well - it would show that it is always worthwhile reading the instructions!

Not talking about undoing, but tightening of reverse or left hand threads.

Yeah, think so- looks to be the same design, though I've only got the low-value one.
