My little chains looked the same at 110 000 km (69 000 miles). The seem to wear out quite quickly till the rollers of the chain start carrying the load agaist the sliders. It is not a fatal problem but it obviously affects timing. The big main slides of the IMS-Cam chain were like new. When you take them out you need to take the oil pump out. Be careful with the IMS when doing that: There must be no tension at the chains at both ends when taking the pump out. And actually, I still think the M96/01 is definitely a better engine than the M96/03. Both have their "characteristics" but the early M96/01 are the most reliable ones with the double row IMSB and coolant calibration by cylinder flow holes. In the 03-engine the 6th cylinder temperature problem is evident.

Great stuff. I just bought a 996.1 coupe 6spd for *very* cheap knowing the cam deviation specs are out of line. I'm showing 8.4 on bank 1 on a warm engine. Car is clean other than that. Looking forward to tearing into it and seeing how bad mine are. Car runs great, but I know it would be catastrophic if I let it go.

@@TopAutomotiveInc First off, I appreciate the video. I don't want to take away from that. I didn't even want to respond but, Porsche calls them what they are - cylinders. And they do not call them "ram pads" they call them guides. German engineers in general aren't big on slang in technical descriptions. I didn't need to but I looked on the PET and my manual to be sure and ram is not mentioned anywhere related to these, so I am not sure where you're getting the idea Porsche calls them RAM PADS. But, I'm not trying to be a jerk even with your flippant response about calling Porsche and complaining. It's just a super basic terminology thing. Nobody on the technical side ever calls them "rams" - that's all I'm saying. And even if they did it doesn't make it appropriate, it's like I said, saying cog or something. People will know what you mean but kind of raise their eyebrows at the term. That's all. I'll leave it at that. Thanks for the vids, seriously. I appreciate that it takes effort to make the time to do them.

@@ericberns9274 No one is disputing that they are not cylinders. Visit the 2 links below explaining different types of cylinders including RAM TYPE and it's not a slang word like you stated. There are many different type of cylinder designs including, double rod, telescopic doubl action, "ram", piggyback, telescopic RAM, tandem etc. So we need to get our terminology from PET ( parts catalog)? Ok, let's dig in! A hydraulic cylinder for a 997 turbo spoiler system is called a "hinge" in PET, is this proper? Oil check valve is called a "cap". These are just a few and the list goes on. Porsche training manuals from a training facility in G.A are not the same terminology as PET. Here is a link explaining the differences right from the engineers. Hydraulic cylinders with large rods and no pistons are called rams. Telescoping ram-type cylinders are comprised of a series of nested rams. Except for the smallest stage, telescoping ram stages are hollow and serve as cylinder bodies for smaller stages. passionengineering.com/products/hydraulic-cylinders/cylinder-types www.google.com/url?sa=t&source=web&rct=j&url=www.hydraulicspneumatics.com/technologies/cylinders-actuators/article/21882647/engineering-essentials-cylinders&ved=2ahUKEwjyjrKdj5vxAhUQlKwKHWrnBXcQFjAHegQIFxAF&usg=AOvVaw26E2vrXocnOga0l8c9QmHh
