can anyone describe or post a diagram of the oil flow in the 12A....where does it go and what path does it follow once it is picked up by the pickup tube from the sump till it reaches back to the sump?

thanx

why?

 

i wanted to know because i was wondering if maybe doing a reverse flow system would have any benefits and i was trying to figure out where the scavenge lines would connect in a dry sump system

 

leave it alone!!! dam ,,you must be bored!!
ive done some mfr dry sump motors, the front cover is $3,500 !!!!

your stock oiling system is fine, dont worry

 

if everyone had to leave things alone im sure we wouldn't have computers and rotaries today...and yes i am bored...and once my mind gets thinking about something i have the undying want to figure it out...so help a rotorhead out

they sell the dry sump system your looking for

 

Ive posted the diagram before if you wanna search for it. Basically, oil gets picked up from the sump, through the oil cooler and filter, down to the rear main bearing and through the dowel pins to the front main bearing, then through the e-shaft to the rotors after which it drains back to the sump.

 

hey revhed i did a bunch of searching and i couldn't find the diagram...pm'd u if u could send it to me or post it here, i'd appreciate it thanx

 

Here you go.

thanx a lot kent

 

No problem. Hope that they help. I think that I have seen the one Revhead posted before on here, but it was easier just to create new pics instead of trying to find the old ones. These are out of the 1985 FSM, BTW. Good luck with your idea.

i guess i was really sleepy and bored last night...wat the heck was i talking about reverse flow oil system...i actually meant reverse flow cooling system...can someone please post a diagram for the coolant flow in the engine. i was wondering...the FSM's that mazdatrix sells...are they original ones, is the quality of pictures n stuff good?

 

nice diaghrams!!
i saved them, for some experimenting thanks

 

bump...can someone post a cooling flow diagram

 

Here you go. This is for S4 13b engines, but should give you the idea.

 

 

From what I've heard, they sell reprints so not all of the images are of good quality (especially photographs). Hopefully, someone that has a Mazdatrix manual will chime in and help out.

has anyone PDF'd the manuals and hosted them online by any chance?

P.S: Kent thanx a lot for all the diagrams...really appreciate it man

 

No problem, man. Yes, there are online PDFs of the FSMs (that is where I got the images from).

1985

1980

1986-1991

Some of the pics in the files aren't that good, but it isn't too bad to work with. I would like to get an original FSM sometime as well. Sometimes it helps to supplement the FSM with the Haynes manual to help clarify what is going on in some of the pics.

i have a haynes...i found a better after market one called clymer at the library in my college. but to tell you the truth...i find both of them quite incomplete...i guess u cant expect too much from an aftermarket book. how much do the Original FSM's go for and where can i find one other than EBAY?
