Re: Head cracked???

Don't bother with a leakdown test, just do a compression test.  If you have low compression in two adjacent cylinders you probably have a blown head gasket.  If you have low compression in one cylinder then you most likely have a cracked block or head and you have to pull things apart again.  I say this because bad rings or pistons will not give you mixed oil and coolant, ever.  Good luck with your problem.
