Jake,

If the spark plugs are new only 100km, I will not be able to see a clean plug.

1) Should I run a leak down test or it will not show anything for a cracked head?

2) Should I have only one head cracked or both heads can be cracked?

3) I heard to diagnostic a cracked head is with blue penetrant liquid with compressed air, one people told me about laser, I never heard of that...

Thanks for all your help guys
