Job # 2022 (BR) - Jaguar Mk II Full Stage One HP engine rebuild

Back to Home

I am pleased to report that we have now wrapped up this Stage One rebuild and we will be installing the engine back in your Mk II shortly.

Another Stage One engine rebuild nearing completion...

	Balancing crankshaft
	Measuring deck height
ARP main cap bolts

We have now completed the machine work on your short block and have the repairs to your cylinder head well underway. The cylinder head was warped and had significant corrosion damage. It also had some inappropriately sized valve seats which meant that the seat pockets had to be welded up and re-sized. Number six chamber also needed extensive welding in the hemispherical dome to cure some deep corrosion pitting and literally every water jacket had to be welded up and re-shaped on the mill.

This head needed some extensive weld repairs and was also warped	Surfacing the block with timing chain cover in place
Machine work now completed on the block	Measuring deck height to calculate precise compression ratio

We have now resleeved the block and completed a much needed align hone. Next task is to hone the cylinder to fit your new CJ forged pistons.
