Exhaust fumes and sound coming from intake

[codyclark65]

I recent pull my motor out of my 2010 Chevy Tahoe PPV and put a non vvt motor in it that was pulled from a perfectly running 2008 Tahoe it is super hard to crank now and when it does it will run for about 2 seconds and the exhaust is coming from the intake along with a little bit of white smoke what could cause this knowing the engine was running perfectly fine when it was pulled ?

When they torqued the heads down did they blow all the coolant or water out of the threaded holes for the head bolts?

You’d know if there’s a problem by buying an inexpensive test kit that goes on top of the coolant reservoir and sniffs out exhaust in the coolant.

Vvt deleted or dod/afm?

Heads were never pulled off

Can you post up a list of parts or the AFM delete kit?

Any luck on swapping the spark plugs?
