Quote from: monterx7;680713really liking your omp lines.....did you assemble them?

Yes home grown - although If I did them again there\'s a couple of ends I\'d change to make the job easier. They weren\'t the cheapest - but they are going to last longer than my old brittle lines.

Were you not going to go for AN4 fittings instead of banjos?

AN3 - but even they are too big on the OMP end.

8mm (M8) Banjo\'s on the OMP end - with AN3 hose fittings, and M10 on the oil injector ends.

The 2 on the rotor housings must have an angular offset - I used 20 degree - but you could go to 30/45 and have less bend on the hoses. Straights are ok for the two fittings on the LIM, but I would possible go with 20 degree in line bends on those if I did it again.

Also on the OMP end - I had to 20 degree and 2 straights, but I\'d swap the 20\'s out for in line 20 bends (the an fittings comes out at an angle in line with the plane of the banjo - not turning up away from it.

Well it fired up after sorting out the CAS wiring (Thanks Papercutout for the pic of your wiring).

Thing is it was shortlived as I had to shut off after only 2 mintures when I noticed oil coming out at quite a rate from the area of the oil filter / sandwhich plate - looks like some of the blanking bolts are leaking big time.

Waiting on battery recharge before I can try firing it again.

I did, also warned the neighbours so they could shut their windows - although it wasn\'t too bad

Ah ok, how did you prime the OMP lines btw?

Prof · March 21, 2010, 05:37:04 PM

I didn\'t - but it\'s cranked so many times and fired a bit - that there will be oil in them now.

This is why people use Engine assembly lube - it gives the engine lubrication during the initial startup stages.

Well done Dave. Nice to see her fired up again. Congrats.

Flooded it trying to get it restarted after shutting it down so early on. I think I\'ve fixed the oil leaks, but really need the engine running so oil system is at full pressure before I know for sure. If it still leaks then I will take the sandwich plate off and run without it for now.

Also, my battery is quite drained - it\'s getting old, and took ages to recharge - so might be off to get a new one tomorrow night.

Will pull the plugs and check them for fuel, clean them up, and crank the engine to make sure any fuel is out.

Wooooo! Good work that man! Nice number plate you have too!

As a side note - whenever I do an oil change, I pull the HT leads out, crank the car over to get the oil round, then plug them back in after the oil light on the dash goes out, and it fires up first time. Admittedly that was on the BMW, but worked fine on the rex when I did that a few weeks back too!

It\'s a good technique - I did \'prime\' the oil system first by cranking it without the EGI fuse to get the oil around the engine.

I think the problem now is that I\'ve flooded it and fouled the plugs, so I will have to pull them, clean them up and give it a crank to clear out any fuel in the rotors. Also need a new battery, as my current 5 year old offering is not lasting very long between charges. I could hear the cranking rate drop as it tried to start.

It did fire up late on Sunday one more time - but I let if dye off before I could catch it, and by then the battery was well gone.

Oh well - a bit more delay is all. :rolleyes:

Well - finally got a new battery and a dry evening to fit it.

Car started up fairly quickly with a bit of persuasion - but as the engine warmed up - the car wouldn\'t hold idle and started to drop out.

I had the laptop plugged in and was watching the AFR\'s - as I let off the accelerator and the revs drop below 1500, they go lean and the engine cuts - so I\'ve a fuel / air mix problem. Could be a vac leak, need a dry day and some time off from work to spend a bit of time on this one.

Fuel pressure seems ok - will have to make a list of things to check. Vac reading was strong with the higher revs - about -0.8, and the even thwop thwop thwop I had when cranking it to deflood it makes me think the engine compression is good. Will have to try and measure it properly next weekend.
