oiltank chopup pt 2 (& some)  sighting the 2 parts togther in the car.  better view?  the idea was to have the oil inlet / feed above the bulkhead / plenuim but with tha space available & being lazy / not wanting to cut off & re-weld a perfectly goof stub I've decided to pipe below / in the cabin (will be sealed in a liquid proof box so safe enough)  here can see my origonal 'cut' & 'top' pencil marjing, looks pretty close for a guess   the top / filler & breather stub, I'm either going to straighten the breather stub or chop off & weld a threadded boss, this allows a smaller hole to be cut into the bulkhead,  the 'cut' tank & bits.  this is the Lotus tank's 'top' - from below! in the round tube is the oil feed in, the round section is to de-aeriate the oil.  this is the tanks 'bottom - looking in from above. (will be now the front of the hybrid tank) can see the oil scavange outlet pipe.  the oil scavange outlet pipe - from the side, this shows (or tries to??) the oil pickup orafice in the outlet pipe, just a hole drilled into it @ the 6'o clock position to stop sucking air if low level. posted this image for tec. purposes..... more cutting to follow...

My hands bear scars that are testament to his advice.

more rambling, would have posted this lastnight but couldn't log in for some reason   chopped the old feed / inlet stub from the old 'top' and will reclaim it as the scavange / outlet (waste not etc.)  clocked to 0.001" and prayed the thinwall aluminium didn't deflect & collapse when machining...  panic over, all safe & I didn't end up wearing the stub   I've pulled the wiring from the pasangerside innerwing area through the bulkhead, this is to create space to work out the oiltank and also to assess the wirng's simplification..  the underside of the bulkhead where the oiltank's filler will poke through.  the loom ran across the bulkhead behind the heater.  taxi heater & loom removed, the heater can now be shifted foreward to the bulkhead, I'll scrape the seamsealer from the top of the tunnel to allow the heater to sit flat & secure the heater to the tunnel with rivnuts.  the floor, between the sill & left ecu / false floor mount stud theres a suspect bit (seen in the photo not actually investigated yet) hopefully it's just surface rust by the sealer otherwise I'll have to get diggin & weldin...  nice clear space, should be enough room for oil & coolant piping also the coolant expansion-tank.  thes only one wire that'll be in this area & that's for the indicator side-repeater on the wing as I'm looking at running all lighting & non-engine related wiring along the drivers side & across the front pannel to the passanger headlight & indicator.  subject of wiring, this is the passanger side's loom, started stripping the unneeded extras out like the rad-fan, +12v 'spare' feed (also eventually all engine related spaghetti) will be shortening / splicing the lighting sections to run in the new position.  my previous 'repair' to the headlight 'earth' wiring, when driving the car home after purchase (& a fresh MOT!) the headlights were flickering & I traced it back to the h4 bulb's plug & small earth wire melted / high resistance.... both sides were repaired.  also, both headlight units are red so have been swapped in the past, they have electronic hight adjusters so from a newer Mx5?  boredom tried to decide on a suitable position for a hydraulic handbrake, the Mx5 is not an Escort or similar conventional recipient for these...  it's not going here! more rambling to come... Rich. |

eventually decided on the brakepipe routing  Mazda have the front flexi-hoses mounted below the chassis & a metal pipe runs down the side of the chassis to connect. I don't want the brakepipework close to the (hot) exhause so have been looking into re-positioning the conection between caliper & bodyshell.  image stollen from the internot & badly marked, the 'dot' is where a bulkhead fitting will pass and the 'arrow' shows the direction of the braided hose (with a 90degree fitting at it's top end) the enginebay side of the innerwingwill probably have another 90degree fitting and the braided hose will run along the top of the chassis to the bulkhead (possibly through the bulkhead then across the car towards the mastercylinder although this might change to have it running engine side to save on fittings...) also decided on the oiltank to pump 'feed' pipework, will have a flexi-hose from the tank to the bulkhead then a welded steel fitting to pass through the bulkhead & along the chassis to connect to another fexi-hose to the pump mounted on the engine.  image again stollen from the internot & badly marked, the 'dot' is where a bulkhead fitting will pass and the 'arrow' shows the direction of the pipe feed to the pump. although these ideas may change!

had delivery of the Laminova parts this morning, a new main body with offset oil ports (hopefully neater plumbing - will see?) some new oil-flanges (slightly taller than the pair I already have) and securing bolts, pairs of steel weld-on' AN12 & AN10 male fittings, Aluminium AN12 weld-on fitting (spare for the reservoir if I have a change of ideas??) and 4 x AN10 / 1/2" bsp nipples.  shiney but not polished, less is more?  unlike the complete unit I origonally bought  the new body was ~ £35 so not expensive to have as an option although I could have drilled the origonal & made bolt-on plugs but for a few £££'s it was easier  also had 1m of -10 (~16mm id) black Aeroquip 400 series hose, this is the same type I have for the oil tank's feed & scavange although the -12 hose is blue in colour - optional but I decided on keeping coolant black to diferentiate. this hose is reinforced & more heat resistant than 'normal coolant hose so will use this around the exhaust area for security (fingers crossed!) now I can start the mock-up  Rich. |

visualising time (I find this easiest as plans can be drawn but theres always something to mess things up!)  my origonal idea was to fit the Laminova here, easily plumbed as near the pump's outlet and can be bracketed from the suspension-tower's gussets (already a captive-nut on the rear gusset)  I'm now looking at somewhere across the bulkhead as it's further away from exhaust heat and also theres an empty space here...  the unit can be fitted in almost any orientation so many possibilities here.... more thoughts to follow Rich. |

couldn't you place it in the chassis leg? seing how far you are going, making a spot there would be peanuts for you :-)

more fiddlin with the tank.  I've cut the oil return out of what's become the top & machined the old weld off then drilled a 1" hole in the lower side for it to live.  the open end of the tube (inside the tank) will have a plate tacked over it & stitched against the bottom to brace, can see the half-moon cuttout in the tube for oil flow.  trying the old 'lid' as the new side, nothing wrong with it so can reuse.  aother view.  would have been rude to not try a Speedflow colourfull fitting...  tried in the car.  the car has a leak, I'm suprised....

another slight tangent but still oil related... decided to assemble a braided oil-pressure hose to run a Real oil-pressure gauge. Speedflow sell a fitting to connect -3 hose (aeroquip type braided) to a 1/8"bspp female thread, also its anodised aluminium but will never be seen once fitted  slide the 'nut' onto the hose.  splay the braid & fit the 'olive'  draw the nut to the end of the hose over the olive.  the fitting has a stub that inserts through the olive into the hose.  insert the fitting & screw togther.  completed end awaiting tightening (I'm going to test-assemble with a steel end fitting to draw the nut over the braid & crimp the olive onto the ptfe hose inner / liner then final-fit the aluminium end.) little jobs take time, ~5 - 10 mins on this fitting & for the oilpressure gauge I'm going to have a split hose with a bulkhead connector and a section to connect to the engine using an 1/8"npt tapered fitting (same as used in Wilwood calipers) back to the engine,  also had a pair of 1/2" bspp brass plugs, I'm making pre-filters for the sump's scavange outlets  I'll solder some mesh to the caps.  that will fit in a tube welded or brazed into the sump's troughs... will be making the tubes soon. Rich. |

Is that wise? You are firstly potentially restricting the oil scavenging ability with the additional filter, and then further masking the filter with the cover.
Personally I would do everything to maximise the flow of oil from the sump to the scavenge pump and let the oil filter do it’s job.
Just my thoughts...😉
