bad oil leak...on the driver side
couple of questions
if you look at the pic i included...
red arrow - points to a sensor...am i suppose to have two of them i think T-II has two
i do not see another sensor or the line that would connect to it...would that be a problem or its just different like that on fd...
yellow - shows area of oil spill
oil went more back on transmission and fuel lines on the driver side
no problem with the engine runs fine....so i am thinking it must be something on that driver side...would there be any thing one that side that would commonly cause this type of problem....
its hard to see i cant really tell where its coming from... so if any one know what it is.....save me from the trouble of puling the engine out....thanks

The red arrow is pointing at the knock sensor, it is in the right spot and there is only one, even on the TII.
There are two o-rings under the oil filter pedestal, these have a tendency to flatten out and leak.
It also appears that you have a steel motor mount on the driver's side, this can cause leaks if not installed correctly as it does not have the supporting "nub" that the aluminum mount has built into it.

sensor - thanks for clearing that up for me....
oil pressure sending unit and oil filter pedestal was also what i was thinking...
originally i was think oil filter pedestal because oil got so high up...it just so hard to see i will tray to get them two things out for inspection with engine still in the car...
can you further elaborate on steel mounts...i think they are installed properly...
can yo explain to me how would that cause leak...
i can take some more pic if that would help... eliminate that possibility...

You either need to install a spacer between the bracket and the oil pan or drill out the hole in the pan and install another bolt.
To eliminate all oil pan leaks install an oil pan brace http://banzai-racing.com/store/FD_oil_pan_brace.html

Ok so now i'm having the same problem
I noticed a leak today on my car drivers side. Oil pan seems to be good & oil spatter is visible on the oil line to the pedestal, around the filler neck, & on the oil filter base itself. I checked to see if the filter was loose but it wasn't. & yes I lubricated the O ring on the filter before install. So my question is anybody ever have a leak between the oil filter & its base? or could it be pedestal O rings like Banzai said? I also noticed oil residue under the throttle body elbow

You may take a look at the banjo fitting for the line that supplies oil to the turbo(s). That could leak and blow oil all over the left side of the engine. That thing is located adjacent to the PS pump kinda under the filler neck. Also check to make sure the two tubes are connected to the filler neck ports.

Both hoses to the filler neck are attached, & i'll check the banjo fitting after work today, But if you look at the first picture you can see signs of oil puddled just below the oil filter? I was wondering if anyone had an issue with oil leaking from the oil filter base...

Ok so I checked the banjo bolt for the turbos & its nice & tight no signs of a leak. oil fill pedestal has both hoses connected, nipple on center housing as Banzai suggested is capped, oil filter base doesn't seem to be leaking from its O rings because its clean in that area too. Only thing I think it could be is the Oring to the oil fill pedestal? the actual oil filter (check out the picture below) Before i took the filter off i noticed residual oil at the right side of the oil filter base if your facing the car. So I took the filter off & if you look closely you can see the whole O ring is dry except one area.. Your probably saying well than change the damn filter! well i am but i just want to try to get any other possible areas knocked out before i remove the OMP this weekend & maybe installing a catch can... Oh yeah by the way the oil pressure sensor seems to be leak free as well..

gravity is always going to put some oil onto the o-ring when you remove the filter, unless it's torn or cut i wouldn't say it is a bad filter seal.
check the filler neck like banzai racing said, and check your oil pressure sender(aftermarket) in your banjo bolt. whatever is leaking looks like it is spraying under high pressure. lastly, check the dowel areas(top of the driver's side of the block) on the front and rear iron for small hairline cracks.

I don't know if it's just the angle of the picture, but it looks like the oil filter in this picture does not have an even seal. (looking at the 6 o'clock position compared to the 9 o'clock position of the filter in the image). Have you tried a higher quality filter by chance (not Fram) ?

[QUOTE=MSTHTD1;10244816Yeah i usually go with mobile 1 oil filters or original Mazda ones but the local parts store only had fram or wix.[/QUOTE]
I'm not one to tell someone what to do, but here's what I did..
http://www.rx7.com/store/rx7/fdengine_maintenance.html
buy the 4-pack of filters. When you have 1 or 2 left, place another order. You will always have a spare available.
Is the filter your problem in this case? I'm not sure. But my brother camaro had an issue once and we traced it down to the fram filter. I'll never use fram again and won't recommend them to anyone.
Good luck!

The oil filter pedestal o-rings can/do flatten out and leak. However I am curious if this mess just appeared after a recent oil change? Often times the filter has a lot of oil left inside when people remove it, it can pour out when lifting.
Based on the ovreall cleanliness of everything the source of the oil has not been leaking long.

Actually its due for an oil change & the car has been very well kept since you've rebuilt it. (chads old 93 ssm) But like Karack pointed out it seems to be a high pressure spray or leak. I plan on ordering your block off plate (OMP) tonight & I'm trying to track down a Damian style oil filler neck & i will replace that o ring while I'm at it. I'm pretty sure its not the oil filter pedestal o rings because where the base meets the block its nice & clean. There's oil residue under the intake elbow, under the banjo bolt/sender for oil temp, oil filler neck & of course along side the block. The nipple on the center iron is capped, I also intend on removing the PCV & installing a vented catch can like Damian's. Quick question on this catch can you guys installed. Did you run one line from the primary turbo to the can & then second line from can to the filler neck?

Take the TB inlet elbow off and see how much oil is accumulating in the TB and elbow. The turbos could be throwing too much oil and it is blowing by the TB o-ring.
The line going to the primary turbo inlet is used to recycle the oil fumes, the other end is the downward pointing nipple on the filler neck. It is not needed when installing an oil catch can. In the car pictured the two lines go to the two nipples on the filler neck.

does that just get removed & vented to the atmosphere? I'm trying to get rid of the oil coming from the BOV. As for the leak i'm going to order gaskets for the TB, & oil filler neck. Is there an o ring on the sending unit or is it a washer?Thanks again for the help,

On cars like ours when the oil filter is facing down, I punch a hole in the center of the filter with a hammer & nail starter. This makes air push down any residual oil left in the filter, giving you a mess free oil filter swap.

I know it aint rocket science removing these oil filters, maybe the punching the hole thing would help someone on this board. I've never had a problem changing these oil filters, I noticed oil at the base of my oil filter & assumed thats where it was leaking from. Gonna put a order in today for some o rings & parts hopefully i can locate this damn leak. Like Karack said it seems to be a high pressure leak? Oh well I'm sure i'll get it sorted out.
