I've had a few issues with the lock nuts on the valve adjustment coming loose. It's particularly difficult on the exhaust side as the turbo restricts access to the lock nuts and I use a bent spanner to tighten them. Apparently not enough.

My solution.

Buy one of these for $7:


Weld (rather badly) the handle to the outside of the 10mm tube spanner.


A screwdriver fits nicely through the barrel for adjustment and then just tighten the nut.

do you not use a torque wrench to tighten the nuts?

how do you find out they become loose?

AusS2000

No torque wrench. You'd need one with an access hole through it for the screwdriver and a hollow extension like the tube spanner.

You realise they are loose when the top end starts making lots of noise.

IMO, do adjustment with a screwdriver+wrench(such as ones you posted or a flex head gear wrench) then tighten with a torque wrench. Afterwards, recheck clearances with feeler. It's a pain in the ass process but better safe than sorry.

Thats very high tech.

I normally just use one of these as its the only thing in my toolbox other than a roll of electrical tape, file and a screwdriver.

You know there is a tool made specifically for this. I just forked out the money for it. I've done so many valve lash adjustments in my time it's paid for itself.

Only difference is that mine is Mac Tools, and I only paid $35 for it.

i used one similar to the one posted above ( on amazon) and it worked great. i think i got it for around 20 or 25 shipped overnight - i forget what brand but it was cheap and made the job as easy as it coul be.

The OEM special tool was 35$ 13 years ago.

Did you weld it with your eyes closed? Necessity is the mother of invention or something like that

I did have my eyes closed, because my dad was welding it and had the mask on.
