So the car was delivered and I specifically instructed the owner, we agreed to use used 1098 pistons with new rings etc so he should take it easy and run the car in properly, check the oil and water before each usage..... The excuse for an exhaust was replaced with a new system from the branch backwards.
I also during the rebuild recommended a new radiator to replace the used item the client opted not to heed my call. Further the suggestion to replace the mechanical fuel pump with an electric unit was also shot down and dismissed.
Then three weeks after the car was delivered I got a call that the car is not running correctly. After getting the car to the shop, it smoked like a locomotive. A compression test was done and all cylinders was within spec of each other, although somewhat down from the initial readings. Black oil was seeping from the spark plug holes. I immediately recommended the engine must be stripped and inspected, the client was very reluctant to comply with my request due to wanting to avoid further incurred costs.
I took the cylinder head off and found the head gasket still in good nick. The hone marks was still visible on all sleeves. I inspected the valves and their seats and also them to still be good. I did the electric fuel pump conversion and blanked the mech fuel pump off in the block. These measures was taken due to the client not wanting to spend more cash on the car. After replacing the head gasket and setting valve clearances, the car fired up again, but IT WAS EVEN WORSE SMOKING EVEN MORE.
I duly informed the client of my findings. Now it became apparent the engine will have to be stripped again after removal. The client asked I must find a buyer for the car in its current condition, they just wanted to cut their losses. I advertised the car for 4 weeks and no proper offer was had. I then decided to step in and buy the car, so a deal was struck. As the new owner I took the engine out. As I drained the oil I found much more than 5 L was in the engine about 7.2L to be exact. It became very apparent that the mech fuel pump's diaphragm had failed and pumped raw fuel into the engine. Further investigation proved the piston rings was toast. No 1 Piston also got damaged very badly. No 1 sleeve was also damaged once we took the micro meter readings for all the sleeves.

Own some minis, break them, fix them, improve them, test them to the limit....
