  • oil leak and icv

    just incase anyone has an oil leak try this first.after finding oil on my drive coming from middle section of large undertray i removed ,cleaned and spent an hour only to trace it back to my vanos.upon inspection i found that the cover for the exhaust solenoids were loose.apparently this is common due to high pressure and that the solnoids push on the covers.i can not notice any change in performnce but no more leaks.i have been advised to change the o rings on solenoids which i will do soon.also every now and then on cold start up my rpm would rise to 1500-2000 and drop shortly after.i removed the icv valve to find it full of soot and connecting pipe had a split.i cleaned and sorted pipe and sprayed maf sensor whilst in bits.,it feels a lot more responsive low down rev range and tic over is perfect.its a bit auquard to get to the icv but worth doing as i thought mine was running ok,it took me a couple of hours but was better than going to local fare in the rain with the kids.
