DDK - Die Deutschen Klassiker

Excellent.
Plan a mini road trip soon and enjoy it all!
11/10 for DIY perseverance.

Valve seat cutting stem using the guide as 'the guide'.

^^^ Struth!!^^

The hot end of one of my hillclimb class mates for the weekend at Shelsley Walsh:

These workings a just the best.
Thank goodness the two of you go about these restorations with such acute focus.
Fabulous to see and read.

Indeed, that is why I though the guide being 'shrunk' when pressed in the head might nip-up the wear on the valve shafts.

MORE head work, the most complex bit of the old 911 engine I think.

I think the engine rebuild kits from Design 911 also have new guides, but you need to check that Rob.

Fresh guide bores may well close things up enough to have a reasonable clearance.

Better than we all give no response!
The Federation is 27 strong plus consultants, plus others are standing up.

Very good choice imho.

Yes, a bit of a gap to allow the ingress of carbon deposit to creep up.
All new valves are expensive!

Simple survey, everyone should do it!

Those days are LONG gone, freedom like this went out in the 80's.

The world is a different place 40 years on.

There is, but if there is a lot (compared to others) then that means there is a LOT of valve clearance, not too tight, just too loose, so would mean the valve will shut just not open much and produce a loud ticking as the parts impact.

All clearances need checking and again to tick them off the list.

There are 3 in my class, the Norma with 500 bhp+ and the Aussie VW special with 500+. And me. Might catch the VW, but doubt it, so it is 3rd for me I think, pointless'racing' for other positions, but will have a go!

Spent nearly 2 hours getting the broken window regulator out of the Boxster this afternoon as it wasn't raining. Part on it's way from Design911, so clearing the debris out now will make installation easier... Always reminds me that modern cars are so complicated and detailed, clips and more clips (...
