Oh no not again...

[itchyfeet]

no

it is a bit easier to turn but then you are not concentrating on the job in hand, imagine if something goes wrong, best leave them alone, one thing at a time.

You need a stubby flat screwdriver to turn tappet adjusters and a ring spanner (15mm maybe can't remember), for locknuts, TDC is when rotor arm points at no 1 spark plug HT lead, adjust no 1 cylinder first ( right front of van as you view from rear) turn engine clockwise 1 4 3 2 or anti clockwise 1 2 3 4 half a crank turn for each cylinder adjust.

Thanks - looking forward to cracking on.Got the tools

STEP AWAY FROM THE SPARK PLUGS, one thing at a time.

Concentrate on the problem....

chap, listen to this advice

[itchyfeet]

all WBX should have hydraulics u less somebody buggered about with it.

After adjustment you van won't start for a few hours minimum, best leave it over night, haynes neglect to memtion this but they are doing a rebuild and so if following that you would be unlikely to get the engine back in in quick.

reason is when you release tappets they suck in oil from the gallery, when you preload tappets again valves open, no compression.
Over night they will bleed down a bit and you should be fine, compression again.

Imagine if you had changed spark plugs as well and it didn't start, then you would have no idea why and would probably assume spark plug problems, thats why you should do one job at a time.

Yeah, he can be nice - at times

[itchyfeet]

Saying nice things about me, must need some help on his van again

[Sir Brixalot]

I'm sadly lacking in that. Had a 30mm socket but the ratchet doesnt lock so I need to go and get the right spanner which will be easier to establish half a turn. None of the tappets are loose to the touch and there are no gaps unfortunately but I'll adjust them and see what happens


On number 3 the first valve was much easier to turn in two revolutions than the others. Is that significant?

Shhhhh, all going well at the moment especially now it has programmable intermittent wipers - don't know how I ever lived without them.

On number 3 the once I've adjusted the screw to touch, I can only tighten less than quarter of a turn not two turns.

put a tippex mark on tdc mark on fan belt pulley and another directly opposite to make life easy

don't understand your comment on no3
no3 cylinded has two adjusters?

adjusting the screw opens the valve so it will be tight but it should turn?

[Sir Brixalot]

I've got a feeling I've misunderstood Haynes. I turned the engine half a turn to move to each cylinder. On each pair of valves I loosened the nuts holding the screw in place. Unwound the screws on each valve, turned them back in until they were just touching then screwed them down two full 360 degree turns and then tightened the nut. I did this four times on the LH cylinder head.

[itchyfeet]

At TDC for cylinder no1 is where you start, adjust both valves on cylinder 1

then turn crank 1/2 turn clock wise and adjust both valves on cylinder 4,

then 1/2 turn cylinder 3, then 1/2 turn cylinder 2

[Sir Brixalot]

Phew. Just sit and wait now for oil to drain back in. I noticed the cover had some scraping inside by valves on cylinder 3

[itchyfeet]

valves should be no where near cover unless cover has been bashed.

did you manage to adjust all with 1.5 or 2 turns from touching?
