Blasting a complete engine !

(1/3) > >>

AshimotoK0:
Here is what I did to blast the outside of a CB350K1 engine and prevent any media ingress. ;)
Everything sealed ..pressurise pipe on breather to a few p.s.i. locked in. Make sure pressure doesn't decay significantly and check all sealed areas with soap solution for sealing.
Blast clean whist still pressurised. Blast with airline..Wash with solvent.. blast with airline again.

Very impressive Ash - what are the red/brown areas around some of the screws out of interest?

AshimotoK0:
Greased fibre washers Ted

Oddjob:
Is it me or does that screw/bolt under the spark plug look too long and is bottoming out on the barrel fins?

Presume you did because finding gaskets is hard?

No it wasn't..  they were just a motley collection of any old bolts and screws to fasten everything together with no engine internals inside. But it shows that a complete engine can be blasted. It may also reveal any leaky seals/gasket faces.
