Re: Escort Sigma 1600 Race Car

Sure is. But on a I don't predict vast havoc in the bottom end this time. I hope I can get a way with just new big end shells. But the journals may need a polish. Or a regrind even but I'm confident the rods are ok this time around.
If thats the case I'll be ready for the 2014 sooner than ever before.

Re: Escort Sigma 1600 Race Car

That is unreal bad luck, hope the crank is ok, is that a roll pin driving the rotor? that is a very poor way to turn the rotor with no keyway and one pin, that Will fail again in time, I would be looking at a better pump and wider drive belt if solid reliability is the aim

Re: Escort Sigma 1600 Race Car

Bad luck or bad judgement when reassembling the pump. I don't think its the pumps fault. It has worked fine for three years untill I reassembled it. I think the middle rotor on the axle is not meant to be dismantelled or reassembled with the old pin anyway. It's not a roll pin. It's a solid pin that needed to be tapped to get it in. And the rotor is heat fitted to the axle so its a very tight squeese. Perhaps pulling it out and back again loosend it up and gave some play to the pin. Also the center rotor needs to be located with a pin since it determines the end float. The other two rotors are keyway'd.

I can't be arsed to fit in a new type of pump, I'll take my chances and fix this one or buy a new similar pump.

I took off the sump yesterday. It looks like I got of easy. New big end shells and a polish to the journals is needed. And the new pump naturally.

Re: Escort Sigma 1600 Race Car

Engine out again


Mains look good


Crank looks decent too except this no.3 journal. We shall see if this polishes out

Re: Escort Sigma 1600 Race Car

Now how nice is that. Polished out perfectly and is as straight as an arrow. And the good fellas of the machine shop tear dropped the galleries too.

Re: Escort Sigma 1600 Race Car

Looks good , when I was at pace products we did some work for a guy that was running something like 207hp out of the sigma engine .
They are so light , that why I am putting one in my light weight 3dr sierra I am building ( turbo,d)
Not long ago I dry sump a sigma in a ford Anglia and I fitted the alt" on the outer edge of the oil pump , fitted well / low slung, and compact ,

Keep up the good work mate

Re: Escort Sigma 1600 Race Car

Yeah, if the dry sump belts could just stop snapping. That would be great.

Sounds like the belt is to tight mate

I really doub't it. It has work as it is since 2010. It snapped first time for some mysterious reason and again due to me F@cking up the rebuild of the pump. But I will be utilizing the oil pressure alert - function in my ecu. It will shut down the engine as the pressure drops under pre set value.

Re: Escort Sigma 1600 Race Car

Well its been quiet in the garage lately. I have ordered new parts but I do believe somethings gone wrong as the new bits have not arrved. But tbh I dont mind since I still have some bills to pay from last summer. No changes will be made to the car. I'll only fix the broken bits and try again (hopefully with better luck) next year.
