as posted in another thread on here, are you all "burpping" the coolant system on your DOHC's and where are you adding the coolant

not the DeGas bottle I hope
on top of the DOHC engine is a metal pipe that runs from head-to-head and then to a rubber hose, which goes down to the thermostat housing..... on top of that coolant pipe is a @1" pipe plug, that is where your suppose to fill the coolant system from on a DOHC engine, as it's the highest spot on the engine and allows the air to escape, which if the system is "air bound" it will make these cars over heat....
