Well A week ago Friday I busted the rear cooling hose coming from the cylinder head to the heater core. It happened on the way home from the post office and dumped coolant all over the engine bay. I stopped the car, dumped watter in and switched the electric fan to full speed I nursed it home with the temp on the gauge never going over 1/2. Luckily the dealer had the hose in stock so I installed it friday evening and refilled the system but never bled it. I drove it 50 mins that evening to my dad's when I got there coolant bubbled out of the resivor tank. The whole way temp stayed perfectly normal and the heater worked great. I then was gone to colorado for a week and when I got back last night I started up the car and headed home. On the way the temp gauge started jumping around and the heat would come and go. I got on the interstate and the coolant light came on, then the temp started creaping I pulled off immediatly and the gauge was at Red when I shut the engine off. I let it cool down and filled the system back up with 1.5 gallons. Once the gauge made it down to below 1/4 I started the engine to try to bleed the system and make it home but there is a terrible clicking noise comming from the cylinder head area. I just got it towed home, pulled the valve cover and nothing is broken, no coolant mixed with oil, no visable external cracks in the head. Do you think I cracked and exhooassed manifold? Blew the Headgasket? or what?
Here are the Compression numbers(stone cold engine, throttle open, 1984 633csi engine)
1-110 psi
2-80 psi
3-80 psi
4-78 psi
5-100 psi
6-95 psi
There was a LOT of steam in the system last night, and the water in the resivor was boiling. Still no signs of coolant in the oil so maybe the head cracked around #2,3,4 cylinders. If it is I'll find a B35 head to slap on along with my B35 intake and what not. It's a shame if it did as I had around $200 worth of work done to it when I stuck it on the engine.(orignal head was the early m30 and
had 5 cracks in it)
