Head gasket leaking?

Just got through repairing my 111,000 mile 92 Dodge Stealth owned since new. New ECU, TCU, fuel pump, plugs, cap, rotor, wires and valve cover gaskets. Runs perfectly now, but I think I’ve got a bad head gasket. Throwing whitish blue smoke out of exhaust, and I’m losing coolant somewhere. Only other thing could be the valve guides. I think the 3.0L motors of that time period were known for dropping valve guides. Any ideas folks? No coolant in oil or oil in coolant.

Not valve guides, valve stem seals.

Thanks for the response. Wonder where the coolant went with no visible leaks.

Out through the head gasket. They all do it sooner or later. Try retorquing the heads. Easy free fix.

Thanks, it’s very strange, as car runs perfectly. It sat for 4 months this past Winter before I put a new ECU and TCU in it.
