[Healeys] Valve clearances

[WILLIAM B LAWRENCE]

The upside of tappet noise is that you can be pretty sure you valves are staying healthy.

I should note the rockers are pretty noisy at 0.015; IIRC I tightened them up just a bit.

I'd go with .016.  You can always tighten it.  Better loose than tight.

Makes sense (for some reason).  I put a DWR1 cam in my BJ8 which, according to DWR, 'is a little better than the BJ8 cam and so works well in any standard or mildly tuned car' but I think the 0.015" applies to all profiles on the spec sheet.

Simon,

Modified cams require the large clearance (don’t ask me why?) So go for .015 that is what mine is.

The car is a MkII BT7.

The BMC manual says adjust the clearances, cold, to 0.012”.

Denis Welch said I should go 0.015”, cold, after fitting their “Fast Road” cam.

The rolling road guy said 0.016”, warm.



I have the radiator out right now so I can get a nice socket onto that nut and have a go at the clearances.

Stick with 0.015”, cold?



Thanks,

Simon
