Hi, my S2 ERST has just failed MOT as my CO can't be adjusted as the screw has seized and been rounded off at some point. Can the metering unit be stripped apart and the screw replaced

 

You can certainly give it a go you've got nothing to lose, but ive had a go at undoing the screws holding the arm inside and they weren't coming un done for shit.........and the mixture screw is a special screw from what i remember, not like a normal screw.

If you fail you have 2 options:

A) New metering head and/or housing

B) EFI (you know you want to )

 

give her an air leak for the mot

 

never thought i would hear such a rough suggestion from yourself.

Tut tut

 

 

Anoys me to hell, got for an Mot and theres your tune down the drain.

 

Bring it over and ill get the screw out for free.

Done it loads of times as it is common.

Regards

 

Fairplay

 

 

Thanks for the offer Jano but with half a tin of WD40 and a bit of patience I managed to free the screw, Car has now passed MOT and is back on the road.............................and thats just opened up a whole load of new problems

 

Fantastic news

Whats the problems now?

 

Bit of a misfire when going up through the rev range while driving, a few rattles, absolutely no oil pressure, boost gauge reads -8 at idle don't know if thats right or not.............but just drivin 20 miles with the biggest smile ever

 

I wouldn't expect it to drive far with no oil pressure.

Didn't you already change the pump?

 

Yeah I changed and checked everything but still no pressure, so its gonna be good bye to this engine and hello new one already on bench in garage, I just wanted a little fun before the big bang

 

Does it sound tappy as fuck when it runs or does it sound quiet and nice?

 

It doesn't sound tappy at all its all nice and quiet

 

Then your gauge or something to do with it is shit. No oil pressure = no oil in the hydraulic lifters = noisey as fuck engine

Does your oil light go out? What type of gauge do you have electronic or mechanical?

 

Its a mechanical gauge and I've also fitted a new oil pressure switch the oil light comes on when the fan clicks in and the gauge reads about 5 psi

 

Hmmmmm

Very strange. see if you can borrow a PROPER oill pressure gauge to get an accurate reading, if you know what i mean it looks just like a compression tester
