I put the dowels in and as these dowels have oil coming up through them, Trig said that he always fits an ‘O’ ring around the dowel, just in case. This ‘O’ ring is not mentioned anywhere in the service manual and does not come in the gasket set. Trig punched out the hole in the gasket just a little larger to accommodate the seal. I then fitted the gasket, trying it both ways round to make sure I had ‘the best fit’. In fact this pattern gasket set has been very good for sizes, shape, holes in the exact right place etc. I then dropped in the cam blades making sure they located correctly.
The extra 'O' ring Trig fitted

Can you remember what size the extra o-ring is Julie, and what size did Trig punch out the gasket to. Nice work on the rebuild. Cheers.

No Roy, I can't tell you the size of the O ring because Trig can't remember ::)
But, it fitted nicely over the dowel and Trig punched the gasket out to the correct size to accommodate the O ring. I'm not even going to have a guess at the size but I'm sure you will find something that will fit and do the job.

Would I be right in saying that the oring section would just be slightly thicker than the gasket so I would imagine that it would be a pretty thin oring and not one of these that you get in the generic oring kits also I think it would be nitrile as there is a fair bit of heat.
