Ok guys yesterday started the car and attempted make another test Drive but every time I turn the car on and the low coolant light comes on my rpms climb to around 3 to 4000rpms what could be the reason why every time I put coolant in the car I see the LIM leakin coolant by the egr intake side of the LIM I deleted it with the zzp blockoff plate and used RTV could that be the issue? Do I need to replace my LIM Gaskets again? I reused them about 2 or 3 times thats too many times? They are the aluminum ones if that helps but what could be the issue? I have a XP Cam stock tune could that be an issue too canned tune is goin in this weekend along with the other mods but before I do that i want to make sure I fix this issue thanks guys

You should replace the intake gaskets anytime you tear the engine apart after you torque them there not going to seal as good.
 
Wouldn't my car not start if I didnt torque them down correctly?

that's your lim end cap gasket. under the egr hole. replace the gasket.

as for the rpms. that's a vac leak somewhere. spray starter fluid around the injectors and lim to see if the rpms fluctuate.

Thanks i'll do that so as far as the low coolant situation just replace coolant with the car on? I know white smoke is gonna come out but it needs to be filled up Engine coolant temperature sensor code comes on too after I replaced it with a new one might be a bad LIM or something... idk but I have a gen v lim im putting on when I do the swap as far as vac leak/sound Its by the throttle body/intake but I will be swapping throttle body's as well
