Engine back from machining! What next!

When I build my motors I use some STP on all my parts to be assembled (like super thick oil additive) and bores. Check that your cam still slides into its bearings if they have been replaced - sometimes they need to be honed to suit, same as the dizzy drive bush.

I also get the high pressure cleaner out and blast the buggery out of the block to get ALL the metal leftovers out - you want to make sure they are all gone before assembly. Dry the motor off and oil up the bores so surface rust doesn't start. Make sure you follow the instructions on gapping your rings - take your time with this, no need to rush it. Do you have a good ring compressor - you'll need one, fingers don't work here.

Check your end float on the crank, you may need to sand down the appropriate bearing if it's a bit tight, once again take your time.
