Getting ready for IVA at Daytuner

Had a call from Damian at Daytuner today who told me that he was having difficulty in mapping my engine for emissions. The car is fitted with a cat and exhaust but was refusing to provide a consistent emissions readings.

Damian has completed compression tests on the cylinders and found that cylinders 1 & 4 are 210 psi and 2 & 3 are reading 190 psi. Given that the engine is supposed to be fitted with high compression pistons, these should be reading of closer to 240 psi. 

He also completed a leak down test which showed up a problem with the piston rings and a small amount of leakage via the valves, this can be fixed by seating the valves with a grind. I'll do this sometime in the future.

The other possible issue is with the high lift kent cams that are fitted and the possibility of valve timing overlap. Damian will swap out the cams for standard ones tomorrow and to try again. 

Hopefully he can sort the emissions and get it down to an acceptable level. IVA is booked for 8th so will need to let them know by Thursday if I need to postpone the test.
