Damn they are great! I went over to Bobs house on Wednesday so he could help me by glaze breaking the cylinders in the squareback. While I was there I also asked him about some piston rings he offered me. The square uses a 83mm piston unlike the bugs that have 85mm. They are a little rare. I ordered some from a VW parts dealer and it took two months to get. Straight from the manufacturer. The oil ring was a 3 piece ring that you have to assemble as you put it on the piston. I bent two of them.
So after finishing the work on the cylinders, Bob goes into his stash and gets the rings-

Individually wrapped in a 3 pack wax paper. Solid one piece oil ring. Went in like a dream.
God, I love NOS parts!
Thanks again Bob!
Love the picture of the pop-up piston (on 1500S engines). Also, I believe the heads do not have the step in the combustion chamber , giving you a boost in compression. Do you burn high test?
yup- and she runs like a champ
It's best Not to "glaze break the cylinders"
It's to long a story so I'll just say an Engineer from Perfect Circle ring co. came to my shop because I was having trouble with rings and it was his suggestion, citing the old glaze was the best for seating new rings. Never had a problem after that.

Very interesting Jack. I was trained by VW of America German trained mechanics. They insisted VW cylinders had to be deglazed when new rings were installed. The theory is that the cylinder walls are so shinny that the rings will allow oil and compression to by pass for a longer period of time. :confused04:; %$oldcit
and BTW- I'm REALLY jealous of Bobs new project!

I haven't had much time to work on Stanley. The pool and yard kept me busy this Summer. After 32 years the pool is gone. Rich, no more pool ice fun in frigid temps! Yeah! I am now fighting the Leaf Wars. I am planning to concentrate on Stanleys' body and floor pan restoration as soon as the leaf battle is over for this year. I have had time to search for and collect needed small, 5 month only, Zwitter parts. I want to start a new build thread soon. :jump4jo": %$oldcit

Sorry, buddy but I have to side with Bob on this one. Before glazing, I couldn't turn the engine after installing cylinder three. It was that tight. Yesterday, I got all 4 cylinders with the heads on and I can still turn the crank.

:confused04:; John, I cant see how deglazing a cyl. would have anything to do with your engine being hard to turn. More like missalined rod cap or cap put on backwards. then you lucked out and put it on the right way.
I always seated the rings, 25mph in 4th gear (after engine warms up) floor it to 50mph, repeat at least 5 times, you'll never have a problem with blow-by.

Yes, putting the engine under a load at low RPMs makes the vacuum drop and rings expand. Therefore seating them into the cylinder walls. thumpup)-
