Ok .. I did the logical thinking thing

Coolant buzzer keeps going off saying I need to add coolant
I installed a new waterpump, all belts are tight, new radiator (well its actually old but new to the car ... pulled from an S4)

I've added two jugs off coolant. And another half for what follows

1. There is no coolant leaking underneath the car
2. There is no coolant leaking inside the engine bay
3. There is not white smoke coming out of the exhaust
4. Compression is around 85-90 on all faces of the rotors
5. Released air bleeder every time and filled up coolant through cap on thermostat (no cap on radiator itself).

Now logic would say that a coolant seal is shot and the car is eating coolant ... but this isnt the case. Like I said .. no smoke, exhaust smells like gas ... I don't know whats going on. The only thing I can think of is that there is still an airbubble ... but IDK why there would be ???

grrrrrrr

 

you have some low compression

 

actually 85-95 is average .. 95-105 is good 105-120 is basically brand new.

 

yea that's not that bad really

 

Based on what you say, my guess is that there IS a leak somewhere that you haven't yet discovered. Try looking closely at ALL the hoses and hose connections for evidence of seepage. Scan the engine compartment carefully in good light. Don't forget the heater hoses and heater core. Good luck!

 

I'm thinking there's air in the heater core (if you didn't put the heater on hot when draining/refilling).

There's a DIY kit at parts stores here that uses UV dye I believe to find leaks, or you can have a shop do it.
