Porsche Engine Parts Inspection Pistons and Cylinders

[@khamul02]

I like this video but it hurts my soul. These are mine but I guess after 150k miles on the car this was to be expected. Many thanks for all of your help inspecting, cleaning, and repairing the parts going in to my rebuild! Keep up the great videos and work!!

Tom, So the pistons live in the most in hostile environment in the engine and the fact that they have survived a 150,000 miles is a testament to their quality. All things wear out in any engine and it is just time for these pistons and cylinders to retire. Thanks again Kurt

Air-cooled engines live a hard life compared to their water-cooled counterparts. Thanks for another informative video, Kurt and Mrs. Kurt :)

What is your thought on coating the skirts?

[@klassikats]

I like and have been doing it our latest rebuilds. Kurt

Great video Kurt and Sarah! Does the Nikasil last on a cylinder with this much wear or should you always send them out for honing and re-coating of the Nikasil.

Paul, It depends on your intensions. This set was just a little to beat up to continue on with. Right now the cost of new Mahle pistons and cylinders are about the same as having a new set of pistons made and the cylinders replated. Given the choice I will always go for new Mahle unless I am doing something custom with bore size and or compression. Kurt

I wonder whether water contamination played a part in those weird marks in that barrel?

[@klassikats]

No they appear mechanical in nature, like something went through the cylinder. Kurt

How can I become a customer? I have an 85 3.2 Carrera with a 915 and would love a motor/transmission rebuild.
