locost online,
I did overlook pushrods as it happens! The pushrod on no. 8 valve is bent (the side of the shaft is actually rubbing inside the head), which is the
same as the bent exh. valve.
I tried to order a replacement today from Burtons, and they can't get any!!

mmmmm MikeRJ - regarding the rule of 9 not working on a x_flow - I had to think about this for half an hour or so just to be sure but (just for a
laugh, and be as technical as you like) I'd like you to explain exactly why it doesn't work on a x_flow.......

Hi D Beddows
Mike RJ is correct in what he says the rule of nine will not work on a cross flow motor with firing order 1243 it only works on four cylinder motors
firing 1342 with siameized ports inlet and exhaust on same side. what you need is rule of five.
start on inlet valves only when number one is fully open set number four when number two is fully open set number three and so on. when completed do
the same procedure on the exhaust valves. cheers davef.

Got to the bottom of the problem. And not great news.
The cam follower must have exploded on impact, coz i found the bottom of the follower in the sump!
OF course, the next question is how to get the rest of it out. I may start a new topic, but you are more than welcome to reply here until i can get
some photos.
Cheers,
Mark

Sorry to be bearer of bad news Mark but it's a strip down to get the follower out.
The followers are put in with engine inverted before cam is inserted.

Just read this thread, bummer on the eventual problem m8.
Just thought I'd add my tuppence worth on the tappets debate.
Although there are many ways to speed up setting tappets, there is one absuloutly certain way to get each valve correct. (especially when a hot cam is
used)
Turn crank till valve you want to set is fully open.
Mark crank position realative to timing mark or any other fixed point.
turn engine one revolution.
That valve is as closed as it will ever be.
Set clearance.
1 turn of crank = 1/2 turn of cam on 4 stroke.

Follower
Yeah it was bad news - took the cam out (luckily it was the first one so the cam only had to came out about 8cm, then i pushed a wooden spoon up the
follower hole and the offending piece popped out.
Put it back together. And it runs! Well, thats a bit o' luck.
Not running"Perfect" but still needs carbs setting up (i said i'd do this straigth after the SVA 4 months ago, but hte thing blew up
before i could arrange an appointment.). Will get this done and a few other tweaks before Donny!
Cheers for a ll your support!!

Don't know if it was a new cam that was fitted but it's always recommended that new followers be fitted with it.
If it's not a new cam and you did a stripdown rebuild then it's important that the followers are kept numerical when rebuilt. i.e. No.1
follower No1 lobe.
Wear patterns match up to each lobe. If a follower from a different lobe is fitted then it's entirely possible to wear down the lobe till round
or shatter the follower.
Wear usually takes place over a couple of thousand miles on a Xflow and the only indication is a slow loss of power finally followed by what seems a
misfire. (Due to no valve lift on the follower)
