2.5 piston ring gap position, "clocking"

[airspeed]

Ring gap position is like asking what is your favorite engine oil, everybody has a different answer. My Chrysler FSM shows the ring gap position to be inline with the wrist pin and each ring staggered 180.  Everything I look at online will show you something different.  I open for suggestions.

I'm inclined to think the engineers who designed the engine and wrote the official factory book probably know more about their engine than other sources, but I'm a bit old-fashioned that way.

 

What year (in case it makes a difference)?

it makes sense for a 180 degree split on ring gap 100%

 

in doing so, it reduces the probability of all the ring gaps lining up in the same area, reducing the loss of compression

 

any other degree's will bring the probability factor up.

 

why chance it?

I split mine 180, however I do have a 4.0. It was what the factory specified so rather than risk burning oil I set them 180 staggered. 

I didn't however gap them exactly the same, I chose how much gap I wanted and filed accordingly. My motor runs great so far  :thumbsup:

If you didn't gap the rings according to factory specs, how did you decide to gap them? And why would you use anything different from what the factory specifies?

I used a gap chart from a webiste that tells you how much to gap your rings based on what purpose you are building the motor for (i.e. racing, towing blah blah). All considered the difference was minuscule in how much gap I filed and factory standards.
