well i was talking to BigJim these past days and he have a problem. he told me that his car start but sound like only have one rotor so i told him to do a compression check by removing one spark plug and hear it doing the 3 chi sound, so he did and he heard 2 good one and a pause on the rear rotor. so i told him it could be a stuck apex so put mmo thru the plugs holes and leave it overnight. so he did and today when to check and did 3 chi in one turn but in the second turn he did it only did two and the third one only did one good one and weak one and a pause. what could it be,does somebody know if the engine need rebuild or just keep putting MMO? thanks

its either 1 or 3 swooshes with a broken seals

its just not seating all that well, get some powerfoam

BigJim

ive got sea foam(same as powerfoam) But is it safe to run my engine long enough for it to warm up? Also can someone give a good explanation of how to do the powerfoam trick

Steve Shulz

Probably a side seal stuck. Never done the powerfoam, just MMO and steam clean. A search should result in something. I think I read hear to follow directions on can for the powerfoam.

BigJim

I think im gonna have to rebuild the engine. I did the mmo trick again today, let it sit for about 8 hours and rolled it over. I got 1 chi noise. Then i got a real weak chi noise and a strong chi and now i get a single chi or a really long chi.

Steve Shulz

Now sounds like an apex. Can you start the car at all? If you can try the water trick, you never know.

BigJim

Last i knew the car would start. I dunno if it still will, but i imagine it would. I didnt wanna start it becasue it might be a broken apex and i dont want it scratchin ****

wwilliam54

i don think its broke, just carbon stuck
take the exuast manifold off and look if you have to

BigJim

That carbon isnt deterriorating thou. Ive used mmo on it 2 nights now and still nothing. Not even any sort ofimprovement

BigJim

i guess ill try mmo a few more days then ill figure soemthin new out+

Rotofire

you might try the water trick if the mmo dosen' work, who knows you mights just be loosining it with the mmo but if yu run warer through it might just wash it all out, i personally am scared shitless of pouring water in my engine.....

Steve Shulz

The thing with the MMO is to get it so the right apex is laying in it. If you have an apex broke and youve tried to start it then you've already scratched the rotor housings. A rotor housing in the scheme of a rebuild isnt such a big deal. Try the water, I dont think there is much to lose at this point.

besides
if a apex seal was broke
you might get one swoosh, but probly none

BigJim

i get 2 strong chi's and one very very weak chi. It isnt fixin, i tried some water, i tried some sea foam/power foam. nothings workin
