Thanks Kurt

Thanks, Kurt

You are very welcome. Kurt

Yes they are. Thanks for watching Kurt

Thanks Kurt

Thanks Kurt

Thank you, Kurt

Our pleasure! Kurt

Glad you liked it! Kurt

Glad you enjoyed it Kurt

I may know Tony, but just not sure by your description. It is a very small community and most of us know of or know each other. Kurt

We could do your engine and make a video. Kurt

Yes we will be installing into the vehicle for the owner Kurt

Thanks Chuck Kurt

We are in Flagstaff, AZ Kurt

@@klassikats thank you

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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EMO7RqLItrA.html

lots of practice and years of working with experienced, and well trained mechanics Kurt

@@klassikats thanks for replying - super impressive!! i’ve been watching porsche rebuids obsessively.. from your experience, what’s the best way to get started on this for noobs?

@@cranklesnacks Read the books, watch these videos 10x. Take an air-cooled-engine re-building class ( if you can find one!) Buy a stand and an engine, tear it down ( take notes and photos, label everything, use lots of containers. Send parts to machine shop, buy new parts, assemble etc. etc...

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. Kurt Kurt

Good to know, OEM Audi pistons and rings are perfect out of the box for standard bore as well. Thanks @@klassikats

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. Kurt

Yes, ring land is part of our checks, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_cZb6NrJSPY.html Thanks for watching, S

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

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. Kurt

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

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 Kurt

No, the water cooled models were another 14 years away. Kurt

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. Kurt

Very interesting, thank you very much!@@klassikats

Hello Kurt, Great video(s)! I have question that pertains to a 356 engine if I may. Regarding piston coating. My piston cylinders are aluminum .Not sure what was the coating. Want to ask can I hone them? Hope you can help. I have asked around told, no and then yes ? @@klassikats

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 Kurt
