I used blue devil gasket repair exactly as directed. prior to that only issue was the smoke after use it's smoking more and service engine light came on. I used my code reader and i recieved a p1217 code. Any advice on what may have happened?

The code indicates the engine is running hot but I have no idea what you did.

That's the thing....I did exactly what I was directed to. I at cols engine temp removed radiator cap drained enough fluid to hold capacity of pour and go blue devil while car was running with heat on max i slowly poured in the product. When finished i replaced radiator cap and reservoir cap and let the car run at nornal temperature for 50 minutes. Shut car of let cool down and when i started it approximately 2 hours later backed out of garage it was smoking crazy and service light popped on.

There is only one way to properly repair a leaking head gasket and you did not do it.

That stuff's a crap shoot at best. The only real way to fix a blown head gasket is to replace it.

Unfortunately i don't have that kind of cash just laying around. As for the blue devil product I know many who have used and it's saved them thousands.

At best that stuff is a temporary fix. Your car was probably too bad to help.

I'm definitely no mechanic however my car actually ran as good as ever just had the white smoke from exhauat other then that no overheating no running hot nothing .

The white smoke is coolant leaking into the cylinders. Keep driving it and the engine will overheat and self destruct. Right now you have a thousand dollar fix. Keep driving it and you will need a new engine. BTW. The code you posted says it is overheating!

You didn’t remove the thermostat and clogged it. You need to remove both thermostats before using the blue devil.
