Hi All,

ok so today I took out my single 1.0mm jet and put in 2x0.6mm jets

When I took out the 1.0mm jet i noticed that the end of it had a white residue on it.

Any ideas on what that could be?

if necessary I can take a pic of it and post...

Cheers

Are you using d-ion or di-min water?

A close-up picture will help.

 

demineralised

i can scratch it off with my finger nail...

 

Are there "white bits" any inside the jet?

Do you have some idea what this residue is? I can see inthe picture a small white dot, is it "it"?

not sure, i will open the jet up tomorrow and have a look...

the whole flat end of the jet was covered in it...

I scraped off the bottom halfish of it with my fingernail in that picture..

 

I forgot to say Happy Easter! Great time to catch up on work and play.

White power is normally associated with aluminium oxide. oxided/corroded ali will produce those residues. I often seen this on ali sheets when left un-attented under the mercy of the elements.

 

hrmm...

the intercooler pipe that I tapped is probably aluminium... could that be the cause it?

thats really the only source of aluminium in my system...

edit - Happy Easter to you and your family too Richard!

 

If there are no bits inside the jet to has to come from the upstream end of the induction pipe.

 

Additionally,

Are you using any methanol? methanol is filtered through cotton a lot of the time. It is known to clog jets and fuel pumps. The white residue found at the bottom of tanks ect ect is cotton.

Thanks

I hav alluminum pipes as well and have not noticed this form on my jets... I use 100% meth. I wonder if there is something in the water?

 

50/50 mix...

I use Elf Methanol - BUT a local place decants it into 20L drum... I doubt that its getting infected...

I will take this jet apart later today and report back...

 

ok i took the jet apart...

no signs of the white powder/coating on the inside of the jet..

so i have to assume that the white stuff is being put on in the IC pipe... probably aluminium oxide or something...

when I have time I will pull the IC pipe and have a look inside...
