See our All of the cabriolet tops experience issues at one time or another. We think this was done so the same head casting could be used for both cylinder banks. Wear in the piston rings and the liners of the cylinder have caused the piston to wobble. This is an article about the M96 engine. A good journalist does his homework!This is data that is several years old and the cumulative failure rate increases greatly with time as the population is not growing.That is true but you still did not do the homework. Absolutely! It is not a good design. Power failure can cause this function to go away and enable the re-learning of the window position function. The Porsche 911 engine is a rear-mounted, flat-six that has been around since 1963. I am pretty sure you have never assembled and disassembled one of these engines and don’t have any experience with other engines to know differences in engine design. Opening the doors should lower the windows slightly, to enable easy access. This develops into a knocking noise sometimes accompanied by a coolant leak. In the first page alone there are several glaring inaccuracies about the arrangement of the M96’s main components–it should go without saying that any analysis predicated on these errors is fallacious.1. Would I gain enough confidence from the knowledge contained in the box set to feel comfortable attempting to build a M96/M97 engine?Anybody who’s a garage mechanic and has a smartphone has probably used YouTube videos to guide them on certain projects. Short version – we got a new Mechatronic unit from Audi, replaced the electronics with the original unit from the Porsche, flashed the TCM to match new software levels and hey presto, a perfectly working PDK!If you have PDK problems and want to try something creative before shelling out for a new unit, you’ll need the help of an expert Many of the older 911 models are starting to experience failure of their catalytic converters and mufflers. They need love and taking care of and they are is engines for someone with soft skin in his hands. The engines used in the Boxster are low displacement versions of the 3.4-litre Flat-6 found in the 996 Carrera. It's been said that a 911 without an oil leak is an unloved 911. Instead the oil winds up at the bottom of the cylinder wall instead of the top. All forces working against a smooth spinning crank. The Porsche flat 6 engine (in particular the M96) has a two-stage intake lifter that fails. Every other car sports a “IMS upgrade” and the resale prices reflect the issues.Really, Porsche guys hate when they think you are insulting their golden chariot or extension of their manhood.I’m so glad these cars have these issues (last I looked, LNE said it was around 2% of these cars that experience this failure over the course of their entire life – not that high!)
The lifter commonly breaks and during the second stage of valve lift, which occurs above 4k rpm, it does not … I did my homework.The Mezger is an entirely different engine with a way more robust design. The engine specs have changed over the years; you can find many iterations of Porsche 911 engines for sale on eBay. Over time these two cables become worn and the result is a sloppy gear change, missed gear or a transmission that refuses to come out of the gear selected.There’s lots of potential for these two cables to have issues at either end. The top tends to shrink and after a few years will not stretch enough to reach the closed position. This has car fire written all over it!The disintegration of the catalytic converter typically causes a check engine light with codes associated to converter inefficiency. However, if the wear is severe enough, a complete replacement of the op-sleeve and the dog ring may be necessary. Have you ever heard that it is different horses for different courses? And mind you, evern Mezgers fail at times. Both of the engines replaced in my cars were from bore scoring on cylinder six.
