Pulled the car off the trailer at home and it sounded like a boxer engine, totally devastated!!!!
To add insult to injury the jerry car i put on the driver seat the cap was not put on properly and it leaked over my seat leaving a pool of E85 on the seat then my bum as i had to drive if off the trailer.
Called Andrew who was already at home and he came round to look at the problem to work out what it was. He used his Oscilloscope on the number 2 injector and it was pulsing so that was not the issue although it could be pulsing and not sending any fuel.
We checked the compression and it was 40psi down on number 2 cyl - my heart sank.
When we pulled the spark plug out it was wet (at the track day it was dry so something changed in that time) It looked like fuel was getting into the cylinder so either that injector was putting extra into the cylinder or we had cleaned the blockage.
The only other thing it could have been was a broken or misaligned rocker that had moved around so we took off the cam cover and found that the exhaust cam lobe on the number 2 cylinder was badly scored.
After a lengthy call to Unigroup the thought process is that it is a porous cam fault causing the wear as there is no wear on the other lobes which could be from a blockage on the oil squirters. They are going to gring down the cam and see if there are any air pockets in the metal.
They are sourcing a replacement cam and rocker and Andrew will put them in and we can take the car back to Unigroup for further fault finding.
