I carry out regular and careful maintenance on my stock 1929 RPU, but somehow, over the years I seem to have missed a vital step. The motor was reconditioned 30 years ago and since then it has faithfully delivered 25,000 miles of trouble-free and enjoyable motoring and still does. The vital missed-step is that I have never re-torqued the head at any time since the motor was fully reconditioning in 1991. I just forgot to do it.

Today I noticed for the first time, oil weeping from the left side head gasket - not large amounts but enough to be concerned about. Obviously I need to gradually re-torque the head to 55 ft lbs as described in other threads. I hope that is all I will have to do - time will tell.

So what is the correct sequence for tightening the head nuts?
