Whilst on the subject of the cam adjuster, I have a plan.
Now the cam adjuster removal is just one of those things that most of us DIY mechanics dread, it will either come out without issues or it won't and just cause a whole world of grief to rectify what should be an easy task to start with.
With that in mind, i was thinking about how best to tackle it and have come up with a plan.
As we all know that bolt can be really tight and just a stubborn thing to shift, even with the correct tool it's not a certainty that things will go as planned.
So, I had a rummage in the shed and found some heavy-duty round nylon rod ,a quick check and it fits perfectly into the cam adjust bolt recess.
I will cut it to size, drill out one end to permit the spline to fit through, and drill-out and profile the other end so the remaining part of the socket fits in snugly. so it will end up being a sleeve for a better description, with enough spline to fit into the bolt but that's it and the nylon sleeve will butt up to the bolt head.
That way there is no sideways movement in the spline tool, it will be central in the bolt head.
My logic is that by removing any sideway movement with the tool, and there is a lot normally, it will have far less chance to twist when force is applied to loosen the bolt, so less chance of stripping the head if the spline gets out a center or moves sideways.
keeping the splined bit in and central is more of a problem on the longitudinally mounted engine than the transverse fittment as you just don't have the space, it's worth a go.
But also buying a decent-quality spline bit makes a massive difference.
I have two, a very good one which is the correct part and is a perfect fit in the bolt head, but the lesser quality spline bit is a loose fit and when viewed carefully it is easy to see how this one would slip and strip the head.
So thats my plan, may just go tits up anyway but sometimes just a few tweaks to something can make all the difference.
