V8 piston rings Hi Guys.. I was checking the ring gap of my new rings when I noticed that the box was missing a spring tensioner on the third oil control ring. 2x times thin steel flat rings separated by a wiggly spring. The wiggly part is missing.
There are 4 ring grooves with the 4th ring being cast iron. Can I just install 3 rings and leave the 3rd one out? Can I install the 4th ring in the 3rd ring position? I've got some old pistons with rings so could I use a second hand piece in the new pistons? Ideas anyone? Regards Kevin |
Re: V8 piston rings The wigley piece is just an expander,,,,the thin flat rings are what cleans the oil off the cylinder wall .
They wear,,,the expander doesn’t . You should be good if you need to reuse one . Tommy |
Re: V8 piston rings Hi Desoto.. the 2nd hand expander is off a +40thou piston. The new pistons are +80thou that is a difference of 40thou or 1mm in metric speak. The height seems right. I'm don't want the engine to chew much oil.

Re: V8 piston rings The expander is the same,,,,,the thin rings should be all that is larger o.d.
If you have new oil rails,,,,it should be good . Tommy |
