Replacement con rod cap bolts arrived Saturday morning - so I cleaned and oiled up all the bits and refitted pistons 1 and 4 with new bolts and torqued them up to
45 Ibs ft without any problems.
Fitting two of the cylinder head bolts into block as guilds, cleaned the surfaces and fitted the head gasket and head - tightening the nuts and bolts in the correct order.
After positioning the crank back to TDC on 1 and 4, I started fitting the timing chain and gear assembly. I will refit the original chain tensioner and check to see if it needs replacing.

This is my record of the restoration of my 1977 Triumph TR7, I bought the car in 1983 for £1500. Over the four years of driving it I had got married, moved to a 110 year old cottage in need of renovation and given a new company car. The TR was parked in the garage (1987) at the end of the garden. I always joked saying "that one day I put it back on the road". Twenty-four years later (Nov 2011) that day has arrived - wish me luck.

Engine rebuild pt2...
Oh the joys of restoration - crankshaft caps bolts torqued to 65 Ibs ft and then the big end caps - tighten them by hand first and with the torqued wench to 45 Ibs ft. Pistons 2 and 3 were fine but a couple of nuts on 1 and 4 didn't seem to be getting there.
I undone both to see if the treads were stripping but both looked ok, so started again and snap! With one bolt broken and the other with a hairline fracture - new nuts and bolts to order.
So with that setback and my finger getting colder, I continued with fitting the jackshaft in to the block and camshaft to the head.
