Cleaning block deck prior to new head gasket

[Pattey21]

Hi there,

I'm in the process of replacing head gasket (timing belt slipped).

 

I've razor blade remove as much as I can but still not completely clean.

 

Should I use a fine sand paper if so 1000+ or scotch brite etc

 

Cheers

Use some wet and dry with petrol instead of water 

did you put stuff in the cooling galleries or are they all blocked?

Get yourself an oil stone. An oil stone is the best way to prepare the surface, second only to proper machining.

I blocked them all up before starting

Hit it with a bit of scotch brite then 1200.

Made a bit of difference but didn't want to get carried away.

 

Feels smooth with a razor but obviously still some marks.

Does it need to be perfect when using a OEM  headgasket

Everyone is keen for the oil stone but it can be very aggressive and if done wrong can make it so you won’t get any gasket to seal
