  2. Sorry I wasn't shouting did not realize caps were on Amy way both heads off found on bank one two valves chipped and bank two eight valves chipped yes chipped how ??? Anybodies guess the heads at machine shop will see and advise no pistons were damaged though
  3. ALL COILS ARE NEW BERU ONES, I AM IN NEED OF TIMMING DATA AND YES ALL THE PROBLEMS AT SAME TIME, I THINK THEY ARE ALL CONNECTED TO TUBE ON INLET GETTING HOT . I WILL LET YOU CHAPS KNOW WHEN I HAVE FINISHED COMPRESSION TEST THIS AM SURE WILL SHED MORE LIGHT THANKS GUYS
  4. Sorry sorry sorry just read on this forum cylinder lay out what I call 6 is actually 7 I naturally assumed as other V8's bulkhead side on left of engine is 5 not 8 Porsche had to be different so number 7 tube is getting hot also misfire there and 5 what I thought was 8 also misfire Apollogise for that error
  5. Thanks Loren thats next step . I took the plugs out today bearing in mind they are brand new with zero miles they had heavy carbon on them I was trying to check if the coils were giving spark cylinder 2 reddish colour spark not white as I expected however it was the same on 6 and 8 yet 6, 8 do not appear as trouble codes at the same time I was trying to work out why tube 6 of inlet was getting so hot I started engine without plug in cylinder 6 still getting hot how ?? When plug is out no fire in cylinder but did detect fait exhaust fumes and not raw fuel which should have been, I think valve issue?? Compression will tell hopefully what a night mere my autodata cd does not cover cayenne so have no data as to timimng chain removal, marks etc uk Porsche dealers not very helpfull either any ideas where I can obtain this on the net?? Thanks for assistance
  6. yes resetting all the time if fuel pressure then what about the chugging sound?? engine sounds as if a spark plug has been taken out whilst engine running very similer to that
  7. hi guys, can any one help i have a 2005 cayenne s 4.5 V8 with 67k miles and full porsche history, the problem i am having is the car misfires and a chugging sound on idle naturally drowned when you accl. i have replaced all the spark plugs, all 8 coils and moved petrol injectors around also replaced inlet manifold gaskets. I also cleaned the two cam sensors with brake cleaner to no avail also checked head bolts in case they are loose no they are not still missing, i disconnected both exhaust systems still the same thinking the cats could be blocked no matter what i do fault code cylinder 2 misfire, cylinder 5 misfire, cylinder 7 misfire when the car is cold it will fire up on the key if allowed to warm up then re-start it will take time to fire up also when running tube of cyl 6 getting very hot much much hotter then the rest, what i cant work out is the connection between misfire and chugging sound almost like a locomotive yet i have no vacuum leaks or abnormal sounds coming from engine, i am totally lost your HELP would be very appreciated
