does anybody have any views o knowledge of this does it work or not

[MrMPuk]

I would think it's just a way of blocking the EGR.

[phil g]

my thoughts as well cant think of anything else

[Nighthawk]

I can't see anything in that picture that shouldn't be there either

If the valve clearences are adjusted to spec and the fuel pump max revs and EGR link rod settings are right, the puff of black smoke during high engine speed gear changes is ok. Earlier 80Ps versions of that engine had what was called an Anti Puff valve bolted up under the banana bunch to stop it......but in true ford stylee.....it didn't work

Save the 4 quid and invest in a set of feeler blades and a 19mm bolt, that'll get most of the settings which affect smoke emissions sorted.

cheers thatl do for me

[dan@dsfplumbing]

reading the chaps feedback it appears to be the installation of a ball bearing somewhere on the egr assembly.

Bizarre.

[MrMPuk]

Prolly a ball bearing to block the vacuum pipe to EGR!

How pi$$ed off would you be to have the postman deliver a ball bearing a little over an 1/8" costing a fiver

If i'd have spent a fiver on that, i'd want the bl00dy world to see it

i have seen this on ebay, at a guess i think you replace the plastic roller on the air intake butterfly valve shaft with the bearing which is of a larger outside diameter than the original roller, thus opening up they butterfly valve a bit more. steer well clear, bearings are dirt cheap from a bearing stockist!

[Nighthawk]

Opening the butterfly passed the the rasied lump on the arm it's doing more harm than good as it's over central and begines to block off the incoming air.

A common mistake people make is to lengthen the rod to make that arm move further because it looks like the butterfly inside is opening further.

not sure i agree with you on this, as standard the butterfly opens only a very small anount due to the shape of the cam, check this with hose from airfilter to manifold removed, i have junked egr and crankcase breather (goes into catch tank now) removed rod from pump to butterfly and cable tied butterfly valve 90 degrees to shut position. runs 100 % better. diesels require a metered amount of fuel at the firing point, they dont care how much air they get as long as there is plenty of it to compress! unlike a petrol which requires a stociometric (sp?) amount of air/fuel 14:1 as my memory serves but could have a decimal? up untill common rail engines they fueling odf diesels has ben pretty basic to say the least, an oddity of the diesel engine due to the fact it doesnt require metered amount of air is you can have full fuel at low revs, i.e wide open throttle in high grears and it wont die! check out truck racing or tractor pulling, tip that fuel into thoes cylinnders + lots of black smoke

[Nighthawk]

If you remove the rubber hose and look at the throttle housing butterfly, you'll see thats it's not closed 100% at rest, Also as you open the throttle butterfly by hand you'll see that it's point of being at 90degrees to the incoming air charge is when the roller is up ontop of the lump(on 76ps) and on the higher section of the track on the 80ps, once the roller comes off the higher point the throttle is over square to the air charge and is in effect beging to decrease the amount of air the engine can pull.

I'm surprised you opted for a messy cable tie, if you simply remove the 2 screws from the throttle plate spindle you can remove the butterfly. That will also kill off the EGR system because it's never got enough vacuum to pull the valve open. The egr valve operates due to the pressure differential either side of the closed throttle plate.

The standyne designed injectors are a 2 stage design with 5 hole nozzles, they begin the combustion process on a pilot injection before the rest of the fuel arrives.

glad i started this, the guy selling em has probably fallen on his sword by now

[madmark]

in all my years of motoring i find it hard to believe you can just tip some expensive addative in the tank and it stops smokeing! personaly i wouldnt buy this sort of stuff i would rather get to the root of the problem like pump timeing etc!

That was the first option till the poxy torx bit broke in the screw head! not got round to sorting it yet
