Out, out damn oil spot

In an effort to isolate the oil leak, I've completely removed the Eurospeed oil plate that links the engine to the remote oil filter and oil cooler, and replaced it with the factory oil filter adaptor. Took it for a run, and it was still draining the engine of oil, so no joy there. It's looking even more likely that the main seal is leaking, so that's an engine out job.

Still, everyone else has had to take their engine out at some point, so why should I be any different?

While it's out, I'll be checking all the bolts I probably didn't do up tight enough, and well have a look at the gearbox to see if we can solve the oil coming out of the breather problem.

On the lean cylinder, I swapped the injectors from 2 and 3 around to see if thats the problem. The injector supply says they've sold 3000 and had 1 come back, so odds are it's not the injector. Actually, I now reckon I've got an air leak in the throttle bodies. Any leak after the butterfly would cause this sort of problem, and seeing as I put it together, I'd put money on me not getting it quite right before believing there's a problem with the injector.

So this weekend will be a case of getting the engine out and having a look before racing home and cooking dinner for the seven guests I have coming around.....

However, this won't stop the engineering process - hopefully this will get done this week, so the paperwork will go in to start the registration. I should have everything put back together before it goes over the pits, which is good because I don't think they'll register something that leaks this badly.

Hi
For your breather problem try welding a small tube with a 90 degree bend in it over the gearbox top plate breather hole, slip a piece of breather tube over the end. Form a loop in the tube and cable tie so loop stays in place. Run open end of tube down side of the gearbox to finish just below base of the box. Make sure when you attach the breather tube to the side of the gearbox that the centre of the loop is in line with bent breather tube outlet. Forms a S bend type trap. Works on Ford Escorts with 5 speed conversions.
