Hello,  I bought this service manual on ebay , and according to this it looks like all engines have the dynatard cam in the E6's, just giving an update,  thanks to everyone for posting and helping.

 

Someone PMed tat info to you

I wonder if that is 4 valve motors only ?

Well my books arrived and I believe we are all slightly wrong here, no offence meant to anyone 

Well the book once proof read from Miss Molly 

 

 

Tells me that Dynatard motors, engines for the sensitive types have different heads with a recessed exhaust valve 

So after a quick glance at the book I  can see that one thing is obvious that is mentioned but not in a big way is timing 

It says to just line up TDC off the indicator on the front the motor indicator

Now me been me and knowing that this indicator is only a indication would mean that possibly a few degrees off here and the whole shooting match is tits up

So thinking a little more about this 

You can get offset key ways to line car motor timing up when building high performance motors

Now thats on precise machined parts, not a bit of tin pointing at a balancer

So Im wondering if TDC should be proven first to see just how accurate this indicator is 

Now a little more 

If only a Dynatard cam is fitted the motor would be retarded the whole time so it wouldn't run, the book says this as well

So with this new found knowledge quite a lot can be learnt

Timimg, valve clearance, good hydraulic lifters or hydraulic lash adjusters as the book calls them are important 

Not the things I was thinking of, good lash adjusters that aren't worn

good rocker that don't leak oil out the rocker shafts

All of these thing might only make a slight difference but combined might make a huge difference 

So now to find that elusive time for some experiments 

I do believe it might be a very plausible thing that some are as good as Jacobs and others are useless like mine
