Now ive got a niggle,

My original washers were plain round , ive fitted the type with the notch pattern middle

What's niggling you about it?


I think the notches are for centralisation (or rather it's 4 bumps that centralise the washer on injector body) - can't recall where I heard that.

Sometimes the bumps are not as thick as the washer itself, I don't think it makes any difference which way up this type goes.

The new ones ain't as wide, but the thickness is better., the original ones where pretty thin with groves in them ? I will photograph one in the morning and post it up tomorrow , I've been out done a 35mile round trip i haven't checked to see if there's any leakage will check in daylight.206 seemed to run smoother when i accelerated there was a puff of smoke but now way as much. My rear new tyres have quietened the ride noise down tyre chap said it looked like one of the old tyres had hit something as it had damage to it .

[MattBLancs]

Odd having grooves in, not seen any like that.

Yes, I've had tyres go noisy with age - some cheap ones and some Goodyear Efficient Grip things that made a din. Didn't suspect them until were changed and suddenly car quieter!

Matt

Ive never seen grooves it was a wtf moment when i took them out.

[Huskyxantia]

The one with the grooved was the ones i replaced ive never seen washers like these.

[MattBLancs]

Well, I'm not sure who on earth thought they would seal!
Thought they would be groves concentric rings not as shown inside diameter effective inside the combustion chamber and outside is, well, outside - so every one of those groves is bypassing the very seal it's seeking to create!

All seems to be running as it should with the new proper type. Mpg has gone up more too

What I was thinking but assumed that smarter minds than mine had that covered.
Same with the centering lugs.

When i got these grooved one out yesterday it was a gut turning moment ,i even showd the wife the difference she's not mechanic anything but she even said they didn't look right.

Oh, I'd assume any work done on a car recently purchased was all completed by an inattentive and disinterested moron or worse still a complete nut case. Very occasionally you'll be pleasantly surprised to the contrary!

Case in point, bought a 306. Am fairly confident it had undergone brake work not long before purchase. Confident as one of the front caliper bolts was loose enough to drop out (and caliper bind up inside the wheel and car quite literally "grind to a halt") less than a week after purchase.

You can understand my complete joy at finding that all four caliper mounts were loose. All but one: presumed ham fisted moron had managed to cross thread that one and torque it up to 150000 Nm...

To be honest matt, when i had the engine all done last year i wasn't to well, so i paid a local mobile mechanic to do the work his hourly rate was good,his knowledge was impressive i had everything done , head gasket kit, timing belt kit , new glow plugs gearbox sorted new solid flywheel & clutch kit ,full. New drive shafts all new brakes front, back,new abs sensors. I reckon when the injectors were removed as the head was skimmed too, they didn't have any washers and found one in the back of there van & relied on the seal below the spacer to do more then it is meant to do ,hence 10 months later the dreaded black death slowly works it way to the top, for the sake of about £3 ish its surprising what can happen.

Random picture from the internet, from here: https://www.indiamart.com/proddetail/serrated-copper-washer-23772511973.html

This is what I had in mind, and would have made some sense, the groves would have reduced the surface area making metal to metal contact (and hence the copper in these contact points compressed more readily, helping make a seal)

I was looking for some with radial grooves like yours (as I wondered what they were intended for! )
Funny, if was a full gasket kit then your chap likely has a set of (the correct) copper washers left over - perhaps chucked in the back of his toolbox ready for stuffing into the wrong application on a future job!

That's fair enough about being ill and getting the work done, we can't generally choose when we are well, and we can't always do everything ourselves either, you have to take a leap and trust folks know what they are doing, it's just disappointing when you find out they didn't after the event!


Anyway, I'm going to stop moaning about poor workmanship as we need instead to focus on the important thing: it's running better than ever!

See what you mean about them type of washers , what diameter would they be , what would use these types , earth moving vehicles ?

Ive had today arrive some more copper washers as a stand by one thing about diesel cars over the 100k mark some injector seals do need replacing.

I think it's engine specific - don't believe the ones in my 306 had ever been touched (and was running fine: 229 thousand miles on the clock) the old 8 valve HDi didn't seem to have issues with "chuffing injectors" but the 16v HDi (particularly the 1.6 DV6) seems to be prone to it.
