    WOW!!! What a masterclass in engine building- thank you for sharing your knowledge. Just learned that a non direct family member that I've seen at gatherings on and off for 30 years is a car fanatic and has a mint 89' 911 Carrera. These air cooled flat sixes are amazing

    This is so fantastic, thanks you for sharing your knowledge and time with us, best UA-cam video! I am reminded of an engine re-building class given by the great Tony, in PA, USA. We also used a Porsche 3.0 SC engine for demonstration. Do you know Tony ? Do all you engine guru's know each other? I will watch all these videos several times, I am sure, in anticipation of an eventual re-build. My '83 has about 145,000 miles and is running strong.

    What is the make and model of ring compressor you are using? I need that! Thanks so much for the video. I have a 1983 911 SC Coupe with the engine about to be disassembled. Also need make and model of the circlip installer. Very cool!

  • @shokrefumi
    @shokrefumi 28 днів тому

    Love the videos! Just a question... wouldn't it be easier to put the piston into the cylinder half way and then put in the wrist pin and circlip? This looks very awkward to pull off.

    • @klassikats
      @klassikats  28 днів тому

      If that works for you then great. For me it is far more efficient using the factory ring compressor and the factory method of installing the piston onto the rod then slipping the barrel on.

  • @TonyVervilos
    @TonyVervilos Рік тому

    Curious...prior to engine disassembly, do you check crank and intermediate shaft end-play clearances, so that any problems can be identified prior to assembly?

    • @klassikats
      @klassikats  Рік тому

      Yes. Kurt is assessing the engine as it comes apart. Cleaning is a continuation of the inspections, and all parts are measured to see if they are worn out or in tolerance. You can check out the clean and inspect video for an insight into some of this. Thanks for watching, S.

    What signs and at what age would a 993 engine need to have the valves and heads rebuilt?

    • @klassikats
      @klassikats  Рік тому

      Most air cooled engines will go about 125,000 miles before heads need to be serviced. An indication that things are wearing out is increased oil consumption, and smoke from the tailpipe after long decelerations or when taking off from a stop light.

    I noticed that you just took the piston rings from the package and installed on the piston, did you check ring gap before or trust the rings.

    • @klassikats
      @klassikats  6 місяців тому

      With stock pistons and cylinders that have been measured and confirmed and using OEM rings that I have verified many times before then yes I can use straight out of the box. Now doing a custom build with different size pistons and over-bored cylinders with custom rings, now that's a different story and I would check every ring and every cylinder.

  • @gorporpio
    @gorporpio 7 місяців тому

    What about the most important measurement re pistons/cylinders - the ring land play? I saw no checking. If the land is close to minimum you don't even need to measure the cylinders. The ring land condition tells you everything to to know. If it's nice, everything else is nice. If it's not, replace.

    • @klassikats
      @klassikats  7 місяців тому

      Yes, ring land is part of our checks,

    @chrismac2264 11 місяців тому

    Kurt, you said these cylinders were Nikisil and no honing and re-ringing is fine. What about Alusil cylinders? I have read you need to keep the pistons in, and check the tolerances for reuse (or replacement). I have also read you can re-ring them. What is your take?

    • @klassikats
      @klassikats  10 місяців тому

      Chris,
      Alusil cylinders are very different than Nikisil. You can re-ring pistons, but you have to be very careful to use the right ring. I'm not sure what you mean about keeping the pistons in. However, the pistons used with the Alusil cylinder are unique to that cylinder design. It is a good idea to keep matching pistons and cylinders together when reusing. Basically, Alusil is just another method to harden the aluminum wear surface. You need to follow the manufacturer's recommendations on what to use with that cylinder and piston design.
      Kurt

    • @chrismac2264
      @chrismac2264 10 місяців тому

      Kurt, thank you for the reply. When I said I read to keep the pistons in, I meant to keep them in the cylinders when removing. This is from a book by Wayne Dempsey. It's an over simplified way to make sure the cylinder and it's piston stay together. I'll do more research on manufacture recommendations for these cylinders. Thanks again for your advice.@@klassikats

      Chris,
      be careful when using information that is not from Porsche. Often many of the aftermarket books contain information that is opinion and not fact.

    • @chrismac2264
      @chrismac2264 10 місяців тому

      Kurt, while Dempsey is considered an expert in Air Cooled Porsche's, your point is well taken. Would you be able to point me toward Alusil (KS) manufacture recommendation material?@@klassikats

    • @klassikats
      @klassikats  10 місяців тому

      I would have to beg to differ. Mr Dempsey is far from an expert.
      The factory Porsche manual talks about measuring and re-using Alusil cylinders. The PET program will also get you the correct ring part numbers. KS also put out a really good document on the design use and repair of aluminum engine blocks and cylinders, you can find it here. www.electrosil.com.au/pdf/KS.pdf
      Hope that all helps

      The cylinders used in this engine are Mahle Nikisil coated aluminum. The Nikisil is plated on to the cylinder and is very thin. Porsche says to only clean the cylinders with soap and water and re-use when they are within wear specifications. Although these cylinders can be honed I have found that it is very easy to go through the coating. I have also found that I have no issues with ring seal on in spec cylinders without honing.

    • @klassikats
      @klassikats  9 місяців тому

      If your cylinders are the Mahle brand, then they are niciksil plated onto the aluminum. This surface can be honed, but the coating is very thin, and it is very easy to go through it. I recommend having a shop that services these cylinders do the hone for you @@davidrodriguez-rk4ee
