How do you know if the apex seals are bad on a rotary motor & can it cause any harm to run the motor when it needs apex seals? Also, approx how much does it cost to have them replaced?? Thanks!
Apex seal replacement is not that hard, it is just that those who know what they are doing are rare and as a result expensive. Also rotary engine work requires a very clean organized work shop.
