<VV> uneven vacuum

[Hugo Miller]

Not unique – a bit unusual by America standards perhaps, where V8s and flatheads prevail – but presumably the valve gaps open up when running? Every other engine the gaps close up when hot. Now that IS unique! As you say, you live and you learn

It’s a unique engine.  The Procedure Seth mentions has served me well for cold adjusting valves for over 30 years. 

Advice?   Listen and Learn,.

Is that correct? I speak as a Brit and a total newcomer to these engines - I 

have seen such a procedure described for TIMING camshafts (and I find it 

hopelessly inaccurate - when does a pushrod become 'tight' to turn?). But 

I've never heard of valves running under pre-load?

Joe - The cold adjustment involves setting the engine to TDC (at the end of 

the compression stroke) for each cylinder and go through the firing order. 

1-4-5-2-3-6. When the cylinder is at TDC, you back off the valve adjusters 

(both) until you can easily spin the pushrods between your fingers (Thumb 

and pointer). Then tighten them down until you take out the slack. The 

pushrod will be hard to turn. Then give it your pre-determined preload, 

often 1/2 a turn. Do both the intake and the exhaust, then move to the next 

cylinder. That is it.

Please advise standard cold valve adjustment procedure.

========================================================

 

 

Same as a Chevy  v8!   Surely your neighbor knows how to do that?
