Now everyone Has dramas with things, my workmates going through hell with his 400 Chev at the moment.
Got the engine running and went to go for a drive and sounded like crap when i put my foot down, like it would just die under any load, spent ages trying to work it out, reset the CAS, checked the afm, i was sure it was the timing but a quick visit to sik em wrex racing found a dodgy coilpack was messing it all up.
After all that about 2000kms later the damn thing decides it doesnt like oil and wants to leak it out from the black oil pan, pulled it off and checked it out, resealed it and again leaking oil, getting very frustrated pulled it off again and found a section was bent, and one bolt had pulled the threads out, funny hoe i didnt notice before, but all is well now, no more leaking.
