Default Coolant Problem

I bought a TI recently and I was running the engine the other day(just idling). After about 1/2 hour there was steam coming from under the hood. When I opened the hood I found something had blown and coolant was everywhere. The next day, I poured water into the radiator to identify where it was leaking from. When I poured some water in, the water came to the top of the radiator and then instantly drained to half empty. When I looked to see where the leak was coming from, it seemed to be pouring out from the rear of the engine. My dad said he thought it sounded like a freeze plug, but is not firmiliar with the M44 engines. I no expert and need some help. Has anyone had this problem or know what it could be??? Any help would be gladly welcomed.HHHEEELLLPPP!!!

It's probably the piece on the back of the head, there are many threads about this.

AFTER you have found/fixed the problem, MAKE SURE that you properly bleed the cooling system. Follow these steps PRECISELY and in this EXACT ORDER. I can't stress enough how important it is to bleed the system properly. Failure to do so can and most likely WILL result in your engine overheating and will put you at a substantial risk of blowing your headgasket($$$)

1) Park the car on an incline so the front is raised

2) Allow the engine to cool

3) Start the engine

4) Turn the heater to full hot(red)

5) Turn the blower on full blast

6) Remove the bleed screw on top of the radiator next to the radiator cap

7) Remove the radiator cap

8) SLOWLY pour coolant into the radiator expansion tank through the FILLER HOLE(not the bleeder hole)

9) Continue filling the radiator to the top until you see a steady stream of coolant coming out of the bleed hole. As you're filling the radiator, tap and massage the radiator and hoses to encourage any trapped bubbles to make their way out of the bleed hole

10) Once you see a steady stream of coolant WITH NO AIR BUBBLES, replace the bleed screw and radiator cap

11) Drive the car around the block, allow the engine to reach operating temp(12 o'clock on the temp gauge)

12) Park the car on the same incline

13) Allow the engine to completely cool

14) Repeat the same process several times until you feel HOT air coming from your dash vents

This I am aware of. The reason my other TI blew it's engine. Not all bad though...Gave me a reason to do an M50 swap. Can't wait to get that on the road. Swapped the engine (M44->M50), tranny (auto-manual), suspension (stock-> Bilstein Sport), and dash (TI->Sedan interior). Should be a blast to drive. Just need to get the Remus exhaust fitted.
