Is it neccessary to replace the metal oil carriers during a rebuild? Anyone know the min. tolerance before they need replacing?


Thanks, Ed

 

Are you asking about the oil pump? Theres a tolerance in the manual thats measured with a feeler gauge.

 

I think he's talking about the oil rings on the rotors.

I always replaced them, but if they are in spec; your call. That little bit of money to prevent a full tear down again is worth it to me. Oil rings are prone to failure, too. Preventative maintenance during a re-build, but thats my opinion.

Ok, well at least replace the o rings and springs. The metal seals are a bit pricey. Like you said, your call.

 

Yeah I'm reffering to the oil rings(metal) on the rotors. I did not know if you guys were replacing them with every tear down. I have a set off a 12A that hardly smoked on start up. I was going to use them on my 4port and just replace the oil orings and springs with ones from atkins.


Thanks, Ed

 

If they are in spec Id reuse them. But Im no guru on this. Just a tightwad.

 

i'll be re-using them on my next build-up. i plan to change the seals and springs only. in the past, i have replaced them, but then again i haven't built that many engines. it's a financial decision this time around.
