How to prep block?


FOSTA

Recommended Posts

Hey guys,

I've stripped down my engine and I'm just about to clean and paint the block.

But I thought it might be best to hone the bores and clean the top of the block ready for its me head gasket first.

 

I just wanted people's view on what's the best way to do both jobs?

 

For the honing I was going to purchase a tool that you plug into your drill and take it easy Going up and down at steady speed and timing how long I take on each bore.

 

Now for the top of the block ( bottom end ) would I just use a rubbing block with some wet and dry sand paper?

 

Cheers guys :)

-Bores: Get them measured and glaze busted by someone who knows what they are doing imo! I presume you're not fitting oversize pistons?

-Top: Clean with a flat gasket scraper tool… Check for flatness with a straight edge and feeler gauges. Inspect for corrosion/damage. Determine if it needs a deck.

 

Then have it dipped and cleaned thoroughly by a machine shop before any painting/re-assembley.

No mate I'm just fitting TT pistons in my GE motor.

 

I take it its not worth doing yourself then.

 

Cheers dude.

can dipping be done at home?

ive been cleaning my head with a brass brush on a dremmel with a can of carb cleaner

it does work without damaging/scratching the parts but can dipping be done at home

 

a friend of mine suggested to leave it to soak in a big tub of petrol and it would be quicker but not sure if thats right?
