These tappets have to be adjusted after a run, not before. If done before a run then the hydraulic lifters have probably lost their pressure and the exact point when just touching the rockers could well be in the wrong position. Take van for a long run and adjust again when engine has cooled down.
There shouldn't be any such thing as an adjusting limit on these as any slack is taken up by the lifters but I have a few ideas up my sleeve that might just help!
I'm free over the weekend although probably working Saturday morning but could pop over... going to send you a PM...!

Van defo shifts. I can get it to do over 70mph - 85 sometimes (if the wind is in the right direction lol). But its not so great going up hill (even slight gradient), but it makes it around 50 uphill on motorway when all around me are belting past.

So whoever told you it was only running on 3 cylinders does not know what they are talking about, take any future advice from this person with a pinch of salt :wink:

Are you sure ?
It is very rare that hydraulic tappets run out of adjustment !

Do be aware when you are setting hydraulic lifters that the push rod is a pain to sit correctly in the hydraulic lifter, sometimes dropping down and resting on the outside of the lifter,
This means that when you wind you hydraulic rocker shaft to contact the valve stem,when you need to wind it in further just ends up opening the valve.
I have seen and heard of this a number off times.

£400 to replace to hydraulic lifters!!!! they are taking the pi$$, you DON'T need to remove the head,
Remove rocker cover.
Remove rocker shaft.
Pull out pushrod.
grab hold of pushrod tube and pull down to bend it (you will be damaging it) to remove it.
Strong magnet to pull out hydraulice lifter
fit new lifter
Buy and fit new spring loaded pushrod tube from CSP (very good quality IMO)
Refit pushrods and rocker shaft
Adjust rocker shaft making sure the push rods are seating properly
Fit rocker cover.
I may have missed the odd thing but this really isn't worth £400,

Nice to have a relative newcomer on here who knows their stuff :ok

Who are CSP btw ? :oops:

I would strongly discourage you from doing 85mph in your van ... or you DEFINATELY WILL need a new engine.

Actually I told her it was only running on three and I don't think most of my information is taken 'with a pinch of salt'.
It was also only doing this on idle, not when over 1000rpm so could point towards compression related problems.
Anyway, I have given Sarah some advice... Which she can take with a pinch of salt or not...! :?

Hey, sorry there, no offence intended :o

Sure, as you say, a test at idle, then a test at driving revs, could easily point to a low compression scenario. Fair point.

Keep helping, it's what we all do :ok

When the AA man came to release the brakes he said that the speedo sensor was loose & the speedo would be showing less than the actual speed. So if the speedo showed 85 what speed were we going :shock: :shock: :shock:

Sensor?? Er.. AA man talking out of his backside I am afraid.. speedo is driven by a cable.. if it isnt in its drive hole on the grease cap and in the speedo head then it dont make the speedo work..

Slightly going off the topic of tappets - What my Ian (bankroller) means is the AA man told us (since he had to take wheel off to free the brakes) that the cap on the wheel (axle is it?) that houses/covers the speedo cable spins freely on the hub and needs to be "packed" with cardboard, or pinched/crimped somehwere to keep it from spinning. We don't know - 1st van and we are not mechanics - so what Mr AA man tells us, we tend to believe (and get verification on here I guess) :wink:

Fair enough, I have not heard of that happening before, but your explanation of what happened makes sense :)

The cap may grip in it's housing better if you distort it a bit ( i.e. bend it a bit out of shape with a hammer !!)

So, the speedo cable controls the speedo dial in the dash and whether or not the the speedo hub cover spins is superfluous to the speedo giving the correct speed?
(because the way the AA man described it to us, because ours is allowed to spin freely, it could be giving a false reading on the dash dial, if you see what I mean)
I just want to understand it bit better (off to van to get my Haynes book out now) :D

This really is off thread........
You said "the AA man said the SENSOR was loose" the cap isnt a "sensor"...... "sensor" generaly means electronic...

and yes it is freely spinning its poss that it will under read.. as said put a slight "distortion" in the cap so it is a tight fit..

The easy way to understand this is to take the big plastic (or metal if original VW) hubcap off the front l/h wheel and look at the aprox 3" diameter cap in the middle of the wheel. You will see a small square cut out at it's centre, and a tiny bit of the square end of the speedo cable should be visible. This cap should be a tight fit into it's holder.
