You are more than welcome any time, I've got plenty of jobs with your name on!!!

All joking aside it would be great to get together, Abingdon is only 20mins from me, you would be welcome to head down the night before a nice easy journey to the track.

I'll have a butchers to see when the first of the season is...

It's a date then!

So this oil breather... As expected the FD is a walk in the park using the turbo oil return...  Our exhausts are in the way though!  Three options for the R3 two for earlier and only one good one.

1.  Tap the sump.  Will be below the oil fill so would need a large breather to be able to empty the oil fast enough to breath before or as the slosh seals the filler tube inlet.  Not great.
2.  R3 could go into the sump extension wing from above.  Only slightly better the option 1.
3. Into the front cover, there is the perfect spot...

The slightly cleaned spot bottom left, nice and high and almost as far over as possible,  will try to weld a fitting onto that scrapper to check there are no gotchas (I hate tapered threads into critical things so will do a weld on AN fitting, could do a simple push fit also).  Will check it works but if it does should be able to do it engine out with a dropped sump only, no need to remove the front cover with some careful ting heat management.

Also took a look at my oil temp sensor mount...  Picked up one of those sensor adaptors no good for temp as the sensor body bottoms out the an10 fitting.


So going to modify a tee to give me some more space...

Will order up an Npt bing and weld it up after filing back the anodised layer.

Personally, If this being mounted in an oil line I would say this would restrict flow.

I would look at either a filter adaptor or a boss welded onto the side of your after market oil cooler.

p.s. running the one cooler it would also be an idea to either mount a second cooler or a much larger cooler ( I used to run a cooler your size on my 4 cylinder cross-flow race engines but your Rotary needs much more cooling)   

Hope this helps
All the best Clive

The first pic is the fitting that I'm not using for the reasons you say.  The second should work as the sensor will be in the side tee.

No filter adaptor will fit the R3 engine...  I plan to put this fitting on the oil cooler.

Clive did you see the notes above about breather positions to stop the oil being pushed up the filler tube?

Really think you should add a second breather on the other side to avoid the problem properly.  Is an easy one for you to add as well to one of the old oil return points.

Many thanks,

Yes made a pipe up from the rear turbo drain plus a 10mm vent out of the front cover.

Yep, I think it is time I listened to the good advice, I need to find a good spot for the second cooler...  Need to stop ignoring this one!  I appreciate your help and advice chaps!

Well some progress on jobs and some issues...

Swapped out the one way valve on the fuel pump, no pressure held even though old valve did seem to have issues.  Swaped the pump as well for the 413 Bosch Motorsport unit 10psi more pressure static, still no pressure hold.  Interesting that either my 044 was tired or the 413 is just so carefully selected that you get better performance than the 044 it started life as.  Either way reset my 60 psi base pressure. Scratched head some more.  Then came across a post on the turbosmart forum that says turbosmart fpr's don't hold pressure pump off...  Well I'll be...

Put some roll cage padding on to meet the blue book helmet contact rules, that went well!

Put a novice sticker on, also went well.

Tried to put a number background on the nose, went badly, number background in bin, tea needed.. Job for another day when missus is not shouting about inappropriate use of hair dryer.

Put some anti-freeze in the coolant as the temp is dropping (I don't think anything would freeze in the garage but better to be safe ehh).

The had a look at the oil fitting.  Turns out the adapted tee is made of some unweldable aluminium, which is common for the readily machinable alloys, Ho hum.  Next plan, new tee tap for m14x1.5 turn down on lathe and use m14 to 1/8ntp adaptor.  I will make this work!

Second time lucky with the oil fitting.  Just the tip in now, that should work well me thinks.

Process was..  Cut top tee down, m14x1.25 tap the centre and then an M14 sump plu adapted (the kind you would use for mounting a temp sensor in the sump).
