new video - shims all out of kilter or is it evidence of a timing issue?

All shims must go back in the same place they got taken out of
if you had new valves .....then you need to put a suitable shims in that provide the correct clearance ...the originals may not be right for a new valve

if you reground the valves ..it will require re-shimming with thinner shims
if you put the valves back in the wrong places - it will require re-shimming with thicker or thinner shims

measuring the clearance should be done with the point of the cam lobe pointing strait up on each one.

The shims are available on ebay ......you need to do some accurate measurements and
then use a calculator and work out what to buy

by putting the slack shim into one you'll be able to work out the difference and order new one or swap one of the others.

Shims may have the measurement on them ...but after running and the cams shaft running over them and wearing them , this measurement will not be the same ..so you need a vernier caliper ..or better still a micrometer to measure the shims.
Only brand new shims will be what they say they are .

all shims are common to lot of ford diesels ..not just the connect .

If you had all the valves out ....when assembling the head ..its then that you'd be working out if the clearances are right .
If you had a valve grinding machine ..it has a fixture for grinding the top of the valve stems.........then on some you could just do that .......
note: grinding the top of the valve stems can only be done on a dedicated machine ...not on a bench grinder! and of course can only be done with the valves out.

all the best..mark

I replaced all the valves with new and re-lapped them of course,and I am sure i put the shims back in their right place but i could have made a mistake.
I'll have to bite the bullet and measure the gaps up and note it all down and, when i take the camshaft out, see if there is something glaringly obviously wrong with the order i put the shims in.
I'll do what you suggest and turn the lobes so they're pointing skyward when i measure.
In light of the fact that all the inlets are too tight, you don't think it could be related to a timing issue? or is this issue i've discovered solely related to the shim thickness and nothing to do with the timing belt?
I'm trying to work it out in my head weather the coincidence of all of the inlets being tight is a symptom of some sort of timing error i've made? or is it just a plain simple fact the shims are wrong for the new valves?...i'm shocked the difference made by using new valves has made to the tolerances

[metalworker0]

All new valves ...means original location of shims is null and void

all have to be measured ...and all may have to be re-shimmed

if you are lucky you nay end up with 1 or 2 that you can use again.

a ford dealership may have a collection of second hand ones for servicing ..they may let you swap some of yours for theirs ..IF THEY ARE NICE!

i think there is a 90 percent chance that this is the main problem!

Hope so. Sods law van will sell on Sunday but at least new buyer has something to go on.
provided i don't melt in the heat tommorow i'll see how much i can get done.

[metalworker0]

looks like you need a tool

[metalworker0]

These tools are so you can do the job quickly and without removing camshaft ....and are as rare as hens teeth

[sparkybandit]

You just beat me to my question about tools

[metalworker0]

well it depends on how much you are paying for these shims that will be useless after you've done the measurement.

if its less than say £2 each .....then worth getting them

Ford dealership want £15 per shim.
Found a chap on e-bay ,he's sending me four of the thinnest he's got to try and if they work send him some £20,can't ask fairer than that.
3.5mm is the thinnest for this engine apparently,he's sending me a 3.55mm so i can use that as a guide to work out the rest,it don't matter if she's tappety it's just to see if she breathes into life.

Have you actually, physically measured these new valves and compared the total length of the new ones to the old ones? Something here seems really odd.

I just wondered, when you had your head off did you mic up the thrust faces on the bores to check that they are not worn; can't remember exactly what their limit is 82.5 or something?

[metalworker0]

well they are not just common to ford , they are common to a lot of cars ...

well according to ebays search ....dont know if you can trust it though



and on ebay they are called valve adjusting discs

and as low as £3.01 inc postage

search""
"FORD VALVE ADJUSTING DISCS"

or to get hopefully quality

Valve Clearance Adjusting Disc Febi Bilstein ford

How did you get on ....you were last seen making out it was ground hog day ..is it still ground hog day

everyday is groundhog day here
give you an update video soon
