some help here .!!!
bacause i have a 13b with one blown rotor , in my backyard , and i want to know if this is posible.

If you have a blown motor you will most likley have to rebuild the hole thing.

But what on the motor is gone. pex seals, corner seals, is the housing warped, blown coolant o ring? Whats wrong with it?

[ShortyDTP]

apex seals are gone.
Because I was looking inside of the exaust port and i could see some pretty big and deep scraches, and there is no compresion at all . but the second rotor is still good compresion .

[FDTT]

Well generly you need to rebuild the engine. If you swap in a different housing a rotor you may run into problems mating the housings.
But if you have deep scratches you may need a new housing and rotor, sounds to me like you need a completly new engine.

tha's why I am asking If i could just remplace the blown housing and rotor ? or i have to do the whole thing . it has 10k on is since the last rebuilt.

P.S is like something when inside the intake and mess up my 5hit.

[FDTT]

Well, if the housing is scored deeply then you will have to replace it. Which means a new motor.

Any idea what could have gine in the intake, or how it got there?

Are you sure you didnt lose a corner seal, and then lose the apex seal?

[ShortyDTP]

No Idea , but i guess is time for me to buy an engine !!

and dig in in this engine so i can see what when wrong.

Thank you !!!!!!!

[FDTT]

No problem, keep us updated on the build up of the engine.

O and if you do decide to tare the 13b apart let me know what happened if you figure it out.
Good luck with it.

[ShortyDTP]

Thank you againg for you help!!

Yes it is, but if you're going to go through the trouble of taking the motor out, tearing it down, and doing all of this work, you really ought to spend awhile doing other modifications to it to make it worth your while... hence, do a 'full meal deal' rebuild on it and replace all of the seals and seal springs, o-rings, get new side seals cut, etc.

I opened an engine that was seeping water but ran great only to replace the water seals. Lost compression on one rotor. Had to replace all seals.
