I'm trying to figure out what I've got in my 78'SC 3.0. I've got the heads off, but I can't figure out who the P/C maker is. I've read that if you have Alusil you should not separate the P/C. You should leave the piston in the cylinders if your not going to replace them. Where as if you have Nikasil you can separate them and even hone and replace the rings. So I'd like to know, because I can see it would be easier to pull the cylinders to remove the piston heads.
Henry Schmidt in 2004 post said "The easy way to tell Alusil from Nikasil is that Nikasil is magnetic."
Well here is the confusion. The outside of the cylinder is non/magnetic, but the inside of the cylinder wall is magnetic. So I think I have Mahle Nikasil P&C's.
I couldn't get a decent photo so I used one off the board. My markings are exactly the same except the numbers are different. Mine are 703 over the same M marking in the photo, and 058 undre the M. Then there is a 0, and a triangle with a 5 in it.
Sorry for the long post,... but this is my first time.
Thanks
Doug
