Chev 216 loose piston pin - which one ?

[Mike Kelly]

Hi

I have been working on my cab 11 C8 , a refurbishment and a general cleanup with the club rego in mind for later in the year .

Anyway the first job is to fix the annoying rattle of a loose piston pin . At this point I don't know which piston is making the noise , the noise has always been there since I got the C8 running . The knock is only evident after revving the engine and then listening as it idles , the noise is not there when above idle speeds .

I am doing this on my own, I know that I can remove a spark plug lead and listen for a change in the knock - but with only one pair of hands . Is there an easier method ?

I have removed the engine covers, a major job in itself

Another query. Does anyone know the dimensions of the valve guides for a 1940 216 engine ? The valve stem diameter and the length of the guides ? I think the 1941 engines are slightly different Thanks
