Valve clearance Question

Post by Cal Walker » Fri Nov 14, 2014 11:45 am

Hi guys,

Just one quick question and I think I'm having a blonde moment! :oops: or stupid!

Am I right in thinking that the circles in green are the inlet valves and the circles in red are exhaust valves?

Many thanks....Cal

yeah thats right,

The valves nearest the carbs are the inlets the ones nearest the exhausts are the outlet/exhaust valves.

Right...... just been out having a fiddle with my spare engine. Just did a quick valve clearance check and the results are as follows:

As I'm a bit new to this and am learning, I can see that I have none within the stated clearances, there all under. On the inlet valves on cylinder 3 I couldn't even get a 0.05mm feeler in there? (the measurement with the * either side)

So I'm basically asking if all my shims are under do they all need replacing to put them in them in the middle of the stated clearances?

Many thanks....Cal

Have you done them as per the Haynes as it has an error in it with the way it explains to measure the clearances.

Make sure you are measuring the clearance between the rocker and the actual shim and not as per the Haynes description that tells you to measure it between the cam and the rocker arm I think!

Yeah followed the Haynes manual to the T, but I did measure between the rocker arm and the shim.

Cheers......Cal

Cal, I'm new at this too and practised on my spare engine on Sunday. I measured using the feeler gauge along the cam, all clearances were .05 mill tighter than measuring directly on top of the shim to rocker arm. In other word, if my feeler gauge was in The middle of the gears, I was measuring correctly. If I inserted it from the outside, then it was wrong. Hope that communicates adequately what I was doing.
If you have done it correctly, and it's worth checking, again, then I guess yes you need shims.
Desperate to start this work on my working motor, now, but there is never enough time is there!
Hope that was of help.
Phil
