That's the proper gasket for a T3 oil return, the square in the gasket is the shape of the face turbo side. As far as I can remember it's always been like that as in square on turbo circle on flange. I will see how this behaves now (Just need some time to use the thing as life is a bit groundhog day at the minute) and if need be look for further solutions as you suggest. Thanks. Ah, I see. That's a shoddy bit of design work by Ford, not like them at all to make a fundamental mistake like that - you soon get "found-out" on rubbish designs when the volume of manufacturing goes upwards! I reckon you'll be fine now.

Bear in mind the design is 30 plus years ago

Bear in mind the design is 30 plus years ago Bear in mind I was designing gasket joints 30years ago as well, it was still known as wrong then! Essentially, either side of a gasket should have a similar shape in the critical bit of the clamped form, otherwise you cannot use "raisers" or "bead-prints" to sort-out any problems in development. Where this joint goes wrong is that it forces the raised portion of the gasket to cross over from the end of the pipe and onto the flange, four times, and unless the whole lot has been perfectly machined (as Stu has now done) then each crossing point is a leak-path. Even then, any possible motion between the two parts of the flange-assembly (fixing stresses, thermal movement, etc. etc.) cannot be accomodated easily in any gasket material. We used to have a saying in the design office, "If it looks right, it probably is!" In other words, you take your artist-head and use that, as it is easier than trying to stress-analyse everything....Oh, how I miss the office. Not.

Well the oil leak seems to be under control today, as Ive had the car out for a good 25 miles or so.
The vibration is becoming less noticeable now, the gearing is somewhat different to the old box, on a brief stint on the motorway it cruises at 70mph at around 2700rpm so it should be good for economy on long trips to Santa Pod.
On the motorway I could actually have my foot down and actually see what the boost gauge was reading, it still needs turning up a bit higher to get it to its previous power. That said its no slouch at the present boost level, a quick tickle in second gear would soon see you in hot water if not on a private road.
Got a coolant hose that needs securing to the inner wing before its next trip out but that shouldn't be any major problem using a rubber lined P clip.

I hate this car at times, tonight we have been trying to sort the speedo controller out. We can't get a signal from the speed sensor on the gearbox, we tried with one wheel off the ground and both. We have checked Haynes and Auto D wiring diagrams so are certain we have it wired correctly, so next job is to remove the speed sensor at work and get the bore scope inside to make sure the pick up ring or whatever it uses is inside. If that is we can then test the sensor off the car with a drill and a magnet and a DMM.
Then there is the issue of the speedo cable itself being too long, so I need to either have a cable made or see if another models part will fit, I'm thinking a LHD escort would have a shorter cable, but searching ebay in German etc is a bit beyond me.
Well its bedtime, I'm filthy and itchy from crawling under the car to get to the sensor, so its shower and bed for me.

OH and while I'm moaning did I mention a genuine Ford VSS is £192.99 ON EBAY.

That is what I'm using at the minute, its not ideal when pushing on as you have to move vision too far between all the different gauges.
We will sort this one way or another its just another of its little challenges.

Treated the old dollop to a brake fluid change today, tested it before hand and the boiling point was down to 166 degrees, minimum temp for dot4 is 155 deg according to out tester, I last changed the fluid in 2016 so its dropped off pretty quickly. All that sitting in the garage last year might have not helped.
Its now sporting dot 5.1 fluid, so this has a higher wet boiling point, I will plan to change the fluid every year due to the location of the turbo to under bonnet brake components.
Needs a good clean again now before a trip to Santa Pod the weekend after next.

Sounds like you have put much more thought into this than some vehicle manufacturers.....it never ceases to amaze me how they get away with running N/S brake lines over the bulkhead so tight to the exhaust manifold. I think that they are worse, in general, on cars that were designed as LHD, then launched as RHD for the UK market, etc., where as little thought as possible has gone into the redesign !!
