Job # 2024 (BB) - 4.2 E Type Full Stage One HP engine rebuild

Back to Home

Your Stage One engine rebuild has now been completed.

We have now align honed the block and have the cylinder honing process well underway...

Grinding main caps square	Align hone in progress
	Measuring pistons
	Finish honing with torque plate

This cylinder head really was in very poor condition. The water jackets in the head valley were corroded and the plug threads stripped out. The only true fix was to weld up the holes, re-drill them and re-cut new threads - all of which has now been done.

Water jacket plug holes were welded closed	Holes were then re-cut and threaded
	Finished result - good as new
Gasket scribing exhaust port	View inside ported exhaust runner

This engine has suffered significant corrosion damage over the years, especially inside the cylinder head. One of the exhaust runner walls actually has a hole in it where corrosion has eaten through from the adjacent water jacket. This hole and the wall around it will be repaired with weld and re-shaped.

Corrosion inside one of the water jackets	Note how it has eaten through to the adjacent exhaust runner
The hole viewed from inside the exhaust runner. The wall around the hole is also paper thin and will be built up with weld	Intake manifold mating surface was badly pitted and was resurfaced on the mill
	Oil pan is cracked in a number of places and will be replaced
Valve covers were damaged beyond economical repair and have been replaced	As bad a build up of carbon deposits as you will ever see
Connecting rod cotter pins loose inside the block	Engine will receive new CJ forged pistons

I am pleased to report that your engine arrived safely and we will have your Stage One rebuild underway shortly.
