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?

 

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.

 

$12.99 from Amazon.

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.
