I have my engine pulled apart for a rebuild. As expected the pistons were carboned up and I dreaded the chore of cleaning. I found this stuff called "Piston Kleen" and let them soak a couple of days. It took the carbon all off! Outside, underside, ring grooves. Some places I just wiped off a little bit. It did a great job. Saved a lot of work and potential piston damage. I just wanted to pass along the good info.
I couldn't find it retail anywhere. Just ordered from the web site. Free and fast shipping. http://www.orisonmarketing.com/pistonkleen.html Edited: I have plain old 1.7 original pistons. When I was researching this, I did see some of the cleaners harmed aluminum. This does not. Just gives you nice, clean, unscratched or scraped pistons. |

and what magic set of pistons do you have? I believe everything I own, except maybe the old Volvo's, have aluminum pistons. rich |

I believe everything I own, except maybe the old Volvo's, have aluminum pistons. rich I, quite honestly, had no freaking idea they could even be made of aluminum and withstand the temps inside an engine. Then again I've never really gone that deep into an engine, other than American stuff. I clearly still have a lot to learn from you Rich. |

There is this http://www.youtube.com/watch?v=dq2z4gN8yZY and this http://en.wikipedia.org/wiki/Hypereutectic_piston All porsches have aluminum pistons. Have been that way since the earliest 356 motor I have worked on. Might have been some early VW stuff that was cast iron...but that would be super rare. Its a weight issue....the lighter weight piston provides more horsepower. Not sure when the american cars finally made the switch...but I started seeing much more american aluminum heads and pistons in the late 80,s and early 90's Two types of pistons really. Forged and cast. The difference is in the manufacturing process. There are also lots of piston profiles, and more recently piston coatings like ceramic coatings for heat resistance, and tephlon coatings for the skirts. Lots of cool engineering between the pistons and the cylinders now. |
