so, a good engine will go pft,pft,pft, pft,pft,pft..... yes?

how many seals are left if it goes pft, , , , , , ,?

two?

time for a rebuild?

we may need a little more info than how many "pft's" there are... like how the engine reacts, when it did it, what you were doing... ext...

what car are we talkin about john? thought you just got a new engine!

If I remember right you should have 6 puffs for every 2 complete e-shaft rotations. Any less means most likely apex seal issues/failure.

for a good motor with all the plugs you you should have 6 puffs for 3 rotoations. Every rotation of the eccentric shaft allows a rotor to fire once.



A rotor with one blown apex seal will make only one puff, with the other chamber plugged up of course. Two puffs would indicate a blown side seal.

thanks for correcting me on that. I wasn't completely sure.

I'm pretty sure that one rotation of the eshaft means two puffs since we displace the entire displacement of the engine per rovolution. Only 4 stroke pissedons displace half per revolution. That's why people call our cars 2.4 or 2.6 Liters. cause a 5.0 only fires off 2.5L per rev, where as we fire all 1.3L per revolution.

Each rotor fires once per revolution of the eshaft. remember the front is doing exactly the opposite of the rear. Hense two puffs per revolution.

here you can see both moving. watch the tick mark on the eshaft and look at both rotors. Two puffs per revolution of the eshaft.

yeah thats exactly what I said... if we wanna get REALLY technical, there should be one puff for every 180 degree rotation of the eccentric shaft

WOW I so read what you posted backwords. I'm lisdexic sometimes. LOL Plus I don't think the drinking helped...
