I’ve done very little else to the car due to the engine still being at the machine shop and I’ve also been busy with my new house. The engine will be back from the machine shop in about 3 weeks time so it will be ready to reassemble when I return to the UK next time. In the meantime all I have done is spray the new radiator brackets in primer to stop them rusting.

Spent the day fabricating new brackets to mount the radiator. I also modified the standard brackets slightly too also be able to mount a Pacet electrical fan in front of the radiator.

I took the block to the machine shop to be measured today. The outcome was that number 5 bore is too badly corroded to even be able to fit 60 thou oversized pistons. However it’s not all bad news, the other 5 bores are in good condition. My 20 thou pistons can be re-used with a new set of rings and the machine shop has said it is possible to fit a liner in number 5 bore. I’ve decided this will be the best option as even if I source a second hand engine there is no guarantee what condition it will be in so I could still be faced with a scrap block or the cost of a rebuild this anyway.

Today was spent cleaning and disassembling the cylinder block. On removing the pistons it was discovered number 5 bore was in very bad condition due to water damage. Although the block may be scrap I decided to finish cleaning the block so I can take it to the machine shop to have the bores measured.

Although I’m back in the UK I’ve had very little spare time to work on the Marcos due to other commitments, however today I had had enough time today to strip down and clean up my heads ready for machining. These were then taken to the machine shop to have new valve guides fitted and hardened valve seats inserted for unleaded petrol
