So, in an ideal world I would never want to see this pipe again…

 .....

I watched Mark remove that pipe in a field somewhere (Newent ) ..... he'd obviously done it a few times even back then!

If it needs a new gasket, it's a 2x37mm. You're welcome to one - I can probably find the little packet of them in the garage, if necessary.

[Dave G]

Thanks for the offer Stu. I’ll bear that in mind.
At the moment I’m just compiling a list of parts I will need when (if?) everything works out.
Cheers,
Dave

[Dave G]

Progress! 1-3-5 head is off.



Slight shiny patches on the inlet valves. Matching shiny on the piston crowns. All others are very dark.


Bores are very, very smooth.

Any damage opinions so far ?

2-4-6 next.

[Doctor Gollum]

If the valves are still true, then reseat them, if not replace them.

Pistons will take much worse to be actually damaged 

[Dave G]

A quick update. Second head off now, and cyl 6 is clearly showing daylight through the valve seat. So they’re all coming out for checking over.



Can anyone recommend a suitable valve spring compressor for these engines ?
Bearing in mind I might only use it 24 48 times…

Cheers.

[Doctor Gollum]

That's your smoking gun alright

[countrywoman]

I used my generic one with swappable end, different dia. Draper or something like that, you will need to tap the end with a hammer to release the collets and a small stick magnet to pick them out. Dab of grease to hold them to the valve when they go back in

[Dave G]

OK. I have a little hammer, a stick magnet (very handy given the number of parts and sockets I’ve dropped), and I have grease.

I’ll have a look at what Machine Mart have to offer for the tool.

Thanks CountryWoman, at least it feels like I’m getting somewhere.

Here you go:  LINK


Used on my V6, several K-series and an A-series. The lever action ones are slightly quicker, but the one I bought in 1990 won't reach modern heads.


I don't use magnets, but cheap pointed tweezers to remove the collets, with a dab of grease to refit them

[Dave G]

Thanks for the suggestion Nick, ordered one Sunday, arrived this morning and all valves now out.
Only 11 quid too.
Cheers 

[Dave G]

Apologies, but I need to ask a dumb question. Just trying a trial fit of camshaft & head parts this afternoon.
I know I have the right shafts for the sprockets etc. but it's just the elongated holes at opposite sides of the retaining bolt holes that I'm unsure about.

Am I right in thinking that the '3' stamp on sprocket 3 (for example) close to the slot means that the locating dowel on camshaft 3 should go into that slot? Similarly on no. 4 and so on.

I've attached a pic and a diagram of what I mean. Hope it makes sense.



BTW, valve stem collets are an invention of Satan...

Not sure if you mean when removing or refitting, but if refitting, I ''glue'' them to them end of a screw driver with a dab of grease & stick them to the valve with a dab of grease.

[Dave G]

Ha! Yes it was refitting. Removing just took seconds with my little mega-magnet.

First pair took me over an hour to get in then I had a tantrum and called it a day.

Next morning I got them all in using the screwdriver and grease tactic in, maybe, a couple of hours.

But my fingers are just not made for that kind of tiny work any more.
