92 hatchback - had a junkyard motor put in about a year ago - not the best job

Had a timing chain put in a few months ago

#2 cylinder is dead - tremendous gas in oil and everywhere when car is running - plus white smoke big time from exhaust

I'm guessing blown head gasket?

No milky oil - just full of gas

I assume lower timing belt has to come off which means oil pan also?

 

how do you know #2 is dead, have u done a compression check? also as I said before
its not a blown head gasket its a injector stuck or leaking o- rings
water in oil = blown head gasket
fuel in oil = injector stuck or leaking o-rings
