DDK - Die Deutschen Klassiker

Thanks for your suggestion but I understood that was something harder... Probably related to valves Before getting up on tow truck I noticed an oil leak... Not so small...(picture)... Only with engine running so I suspect rocker arm axle out of his site...this would explain problem on valves and oil...

Dear all Unfortunately ending my Dolomiti run... Before getting home Suddenly my 2,2 T my 70 loose power and start hardly backfiring from cylinder 6... Initially changing noise and rpm when idling without spark then no more but squitting at idle and banging if accelerating... Waiting now for trailin...

@fethuoe if I correctly undestand I fear that I made the mistake to let the operator print both graphics on the same page but with only one vertical scale. Before printing he showed me on the monitor power and torque on separate graphs and I shot only power (follows) http://uploads.tapatalk-cdn.com/...

Thanks to everyone of you Gentlemen for tour considerations: @Ashley: you're right I'll continue to enjoy my 123hp powered that seems many more :) @911hillclimber: I'm italian and I understand you perfectly: I wait late sunday evening to get out and drive or I go diretcly to Slovenia(I'm close to th...

Dear all Gentlemen Today I rolled my car on a dyno and results are pleasently a confirm of standard power (123 hp) although at 5200 rpm...less than 5800 that Porsche declared...

Dear Gentlemen Finally air duct fitted, very tight and uncomfortable to fit it properly workng between engine cover and housing fun... ...and I understood why people don't refit it... Many trouble to fit it... And moreover standard screw of alternator that is not the first equipment bosch are not lo...

@Jonny Hart thank you so much for you super-useful link!! I need longer bolt to screw the hub extension... I found these with less thread http://uploads.tapatalk-cdn.com/20190426/43a0bcd8658622e392e2a654b4ccc42c.jpg Compared to the actual installed http://uploads.tapatalk-cdn.com/20190426/e1a4874fe9...

Dear All I finally found a used air duct to replace my missing unit... Just a doubt about correct position (it could be fixed rotating it by 60 degrees up to 360 degrees wrong...) If I refer to Porsche Spare parts catalogue (number 13) http://uploads.tapatalk-cdn.com/20190425/f8704fbf829e5a2b9d79efe...

@neilbardsley thank you for your question.
My concern is if the car is really properly tuned with a std set up on a not properly std engine

Thank you for your supposals @fetuhoe Now my concerns are: If my engine got a sort of "tune up", with specifics set cams phase set up... (E model or similar to E model or simply "unique"...) but my local dealer porsche that follows only original specs phased it as an original one...

@fetuhoe thanks for your consideration: cylinder are original(according to code on them) as I presume pistons: engine has surely received a "head" refurbishment considering the oil chain tensioners installed. I think that no other rebuilding have been made. Mileage is 86.000 and seems corr...

Thanks @yoda
@bootsy: yes I have SSI stainless steel exchangers+muffler kit
