361 - Project

:open_mouth: hmmm…steffan, u know they make piston ring pliers, spreads them quite nicely. makes me hurt just watching u. -just my $.02 – j

Dan,
ah - hmm you got me all stuttering now ….

Jeremy,
I know that, but I didn’t feel it on the first and second ring. Later it wasn’t worthy anymore! :wink:

… and here come the next pictures…

  • … as I already mentioned: The parts that appeared to be reusable, at this point are not good enough anymore to go into a new engine.

  • Today one more parcel with new parts arrived, including a new shaft and bushing and that means…

  • …I can finally start to reassemble the new fuel pump

  • new sealings

  • Egge had an oil pump overhaul kit that included everything except the housing, but here even the housing is new.

  • pressure valve and spring

  • ready to bolt the two halfes together

  • O-ring and …

  • that’s it :slight_smile: Not a big deal. :wink:

  • Also the port for the distributor drive shaft was covered with sludge. Now it’s clean again and…

  • ready to receive the new oil bushing. Some oil on the surface and the new bushing will go in easier.

  • The old shaft is a good tool to drive the bushing in place.

  • Using a strong screw driver the new bushing goes in place.

  • Almost done.

  • For now there’s nothing more to do on the bottom end, except waiting for the next parts to come. To protect it from dust I wrap it in plastic. I think it’s time to go for the cylinder heads now.

Hello Group,
here comes the next bunch of pictures:

As I’m waiting for the next parts to come I’ll use the time for the cylinder heads.
Do you still remember these pictures …

  • 705 - cylinder head?

  • rusted and/or burned valve seats?

  • slugged valves? … and …

  • here some more…
  • imagine the nice valve guides

Well, that’s all over now and it’s a real pleasure to see how the work goes on.

  • clean heads with glass blaster

  • Some valve seats have been almost “eaten up”, so I didn’t really have a choice. Hardened valve seats is not a “nice to have” feature, in fact it was the only way to go.

  • closer view

  • slugged valves are a sign of worn valve guides. Take a closer look and you’ll see the new bronze guide

  • … from outside

  • machining valve seats.

  • more pictures
  • decking the surface
  • heads with valves

  • and here the specialists from the machine shop -
    Rectificadora de Guimarães.

  • Meanwhile the intake manifold came back from sand blasting. Untill today it’s an enigma to me how the the carbon could get inside of it. It’s almost clean now, but …

  • … bad news. The intake manifold has a crack.

  • Well, it’s time to reassemble the heads. The weather here in Portugal is still good, but it can change in an instant and become wet. It’s better to hurry up now.

  • The valves came with the engine overhaul kit from Egge. If I would do it again, then I would invest a little more money in better valves. Some of the valves showed a little difference on the head. Although we are talking about very small differences it causes a different pre-load on these valves. I had to make some shims to achieve the correct and equal pre-load.

  • see the pictures.

  • more pictures …
  • and more pictures…
  • and that’s it for today! #1 exhaust valve is inn.
  • Same procedure on the intake valve.

  • The only difference is the valve stem seal

  • … and on this valve I had to use a shim
