IÔš'm new to E30 Zone, had some fun reading round the group, but now is the time I need some help and advise.
IÔš'm running an E30 318is M10 1986. I have known the car for a number of years it has good history and wanted for nothing over the years. Now I have the car itÔš's decided to develop an over heating problem. In the time I have know the car its always run a little on the worm site for my liking but has never boiled over, it urns just over 2 thirds on the temp gauge
Before I obtained the car it had been stored off road for about 5 months, Before I re Mot`d the car, I ran through usual maintains, including replacing the coolant and oil ECT.
Now the car is running ver hot, while driving round it still runs to 2 thirds of the temp gauge, how ever sat in traffic the temp runs into the red which I feel could be a little dangerous.
On checking the oil, there is no site of water in the oil and the same for oil in the coolant system.
The Rad was replaced with a second hand item 4 years ago, even though I had change the coolant my self the water had turned I nice rusty brown colour, on taking to a local garage I was advised to replace the Rad thermostat and back flush the system, which they completed.
Since then the car has run at 2 thirds the temp scale even sat in traffic, and has run quite happy for about a week now until Tuesday when I hose split.
The hose in question runs from the water pump to the T peace on the side of the thermostat, the hose split with a small hole close to the water pump.
I have replaced the pipe and refilled the coolant system. Then ran up to temp and ensured no air locks in the system. Since then the car has ran up to temp, but the hoses appear to be pressurised beyond what I assume to be normal. When trying to press the pipes they are hard as rock and look under stress, and have started seeping water.
One a compression test all 4 boars give 170psi, and again no water in the oil, or oil in the water. Now IÔš'm at a loss, do I have blow head? Please help
Regards
