Is there nowhere on the chassis rail where you can position the remote filter housing? The Mocal one that I used needed a vertical face for the bracket to bolt to. This was on an XE in a Westfield, not Mazda. I'm well versed with the bloody needles on braided hoses, think I first assembled one in 1992  as to shiney anodised fittings, as test / setup I'm looking into 'pre loved' fittings partly to save a few £££ and also as I'm not 100% on the system so its getting a test-build  still £5-10 per fitting & I need 14 to plumb the oil system. scavange system (AN12 / -12) - from pump to cooler to bulkhead to tank then from tank to bulkhead to pump. pressure system (AN10 / -10) - from pump to filter then to engine. as to filter location, I'm thinking about...

more expense.....  ebay again, secondhand AN12 Torques aeroquip style fittings & -12 Aeroquip hose, this is the 'push-fit' type and great for test-builds although once the pipe is on a fitting it will need cutting off as they're not meant to be dismantled   hose specifications... I'll inspect & pressure-test the hose before making the required lines, although I'm looking at these for test-build they need to be servicable so it's a secondhand purchase gamble next to find that coveted Laminova cooler Rich. |

I used the push fit aeroquip on my remote oil filter + jubilee clips, no problems, and a lot easier to assemble..

The fittings look much the same, reading the spec sheets it looks like they have changed the hose construction.

I did collect a B6t engine...... so, maybe it has the 't' specific parts like stronger conrods, lower-compression / stronger pistons, shorter-duration exhaust camshaft, sodium-filled exhaust valves  it definately has the external items specific to the 323 turbo car so I can hope... also, it seems to have a slightly different cylinderblock to the 1.6 I have in y cars & stripped in the workshop, one is the alternator mount boss seems to be shorter photo's tomorow when I dig it out from the back of my van also had the AN12 / -12 aeroquip hoses delivered, bigger than I was expecting!

daylight photos of the b6t engine from a 323 turbo (4x4), forgetting the obvious differences (camcover & inlet manifold) theres a few others....   can see the rear mounted thermostat / coolant outlet, the 'famed' designed coolant path?  turbo coolant feed stub, oil feed & return ports, also different flywheel to an mx5's 1.6 b6ze(rs).  coolant manifold and front dipstick.  small diameter 'washer' on the centre bolt so snc? the 'inlet' side has other differences, will photograph later  also had a delivery of oil hoses......

Is that salvageable Zed.? It looks pretty corroded to put it mildly? Some interesting differences though. |

Is that salvageable Zed. ? It looks pretty corroded to put it mildly? Some interesting differences though. thats just surface corrosion, nothing to worry about for a 'barn find'  I've lifted the head from the block for a looksee & apart from a burnt exhaust valve in number 2 cylinder all looks good (so far!) the pistons are the correct 'turbo' type with the deeply dished crowns & what looks to be very deep valve-cutouts (although these could be standard, I'll reserch some about this...) anyway, photos as we all like visual-stimulous   front of engine, different pulleys to those used on Mx5 engines, I've read the Mx5 pulleys were designed to be lighter but have not weighed these so unsure 8slot pulley = longnose / bignose crank? NO it's an early shortnose I am not suprised about the crankshaft.... ![https://i.imgur.com/QEtCW1i.jpg[/img]](https://i.imgur.com/QEtCW1i.jpg) top of engine, can see the different throttlebody & inlet manifold.  back of engine, can see the arrangment of coolant pipework.  side of engine, lots going on there!  another view, can see the extra breather that has a return to the sump, obviously Mazda decided the extra 'blow-by' rom fi was needing oil/vapour control  the oil seperator, theres a small-bore pipe that would go somewhere! no idea where though as theres a few 'spare' stubs on the manifold and it could even run to the airfilter??  the cylinderblock & sump connections. on Mx5 1.6 engine cylinderblocks the stub is fitted but has a rubber cap as is unused.

your B6T is shedding its skin on some of those parts lol.

your B6T is shedding its skin on some of those parts lol. tis just the black crinkle-finish paint on the manifold & camcover, subject of camcover, will clean & sandblast but I don't know if I'll use it as the 'need' of the different look is not helpfull Rich. |

more b6t images  top face of cylinderblock, can see that the headgasket put up a bloody good fight before releasing the head, needed 'Peter' (the hammer) to persuade it to move! number1 cylinder had some rust due to ~30 years storage with the valves open so I gave it a quick lick with sandpaper to remove prior to turning the crank - all turning nicely so thats a result  can see the deeply dished piston crown, the '115'hp 1.6 pistons have a partial dish of 1mm depth in comparisson & this is maybe 4mm by eye?  the chambers & valves, also can see the headgasket material that refused to release the head, was verry well stuck down!  number 2 chamber & it's burnt valve... so now I know why the engine was not in a car but I've the feeling it was then sold off as a good unit to be a spare for a rallycar it's amusing to me that this has happened as evryone chirps about Mx5's suffering with bad coolant flow / overheating of number 3 cylinder that can be cured with a 'reroute' (to copy the origonal 'fwd' / transverse design ) this is an origonal fwd head with the rear coolant outflow & it's suffered a heat issue 3 cylinder positions away from the outlet....... hummmmmmmmmm....

Rich. Hmmmmmmm indeed, I think there is a lot more to it that just the coolant route and adding in seperate oil cooling can only be a good step to preventing this and keeping the overall temperatures down at peak points. Even with the correct routing, theres only so much ability the coolant system has to cool an engine. Have you figured out where your mounting the oil cooler yet.....?  |

theres only so much ability the coolant system has to cool an engine. sorta true, I've reserched & played with other engines & seen some pro-tuners answers anything from drilling extra coolant passageways to blocking some and even external routing from block to head with no coolant through the headgasket (Ford / Cosworth's ' BDT/e' if you want to look it up?) I'm still tempted to make a copper sheet gasket and 'wire-ring' the cylinders - just to be different Have you figured out where your mounting the oil cooler yet.....? oilcooler mount? Definately NOT outside the bumper like your photo the 'Because racecar' style may be good in carparks but it's vunerable & has no airflow (if mounted in front of the bumper ) and I think it looks messy  on a serious note, it'll either be in front of the coolant radiator OR I'm tempted to get a Laminova cooler and plumb that in between the rad & waterpump www.speedflowshop.co.uk/laminova-oil-to-water-coolers-174-c.aspand, luckily I tripped over a '5 that had one fitted so look something like..  ^^ image found via google somewhere EDIT...found origin, post 18 forum.miata.net/vb/showthread.php?t=248593Rich. |

Sandblasted the 323's camcover today, it's just finished it's time in the Partswasher  minor improvement from before!  some covers have a breather-stub at the rear, this doesn't (maybe the normally asperated version has?)  the single breather stub was removed, I'll tap a thread in the hole to suit either a bsp or AN type fitting depending on what fittings I have that are closest to the correct size  underside.  the breather / seperator chamber, just the single small plate covering this even though the casting has positions for another central breather but the rear is undrilled so didn't have anything fitted. so, the big question.... Do I use this cover on my engine? I'll be honest & admit that I'm not a fan of these compared to the normal Mx5 type but I may use it in honour of the friend who forgot had this in his shed for ages Rich. |
