Hi Guys, I'm brand new here and have joined firstly to seek advice/diagnostic for my engine troubles.
I finished a complete restoration of a '76 SWB S3 truck cab with a galv chassis and 200 tdi this spring. Using it every day, loving it, running perfectly. Last week after getting out at a destination I found the radiator bypass hose had burst and grey emulsified oil/water was spewing out, making a hell of a mess. The whole system was under high pressure and there was a lot of oil in the water, so much so that the oil was below the dipstick. I leapt to the conclusion that it was a head gasket which I duly changed last week including having 4 thou skimmed off the head while it was off. To my great disappointment, the problem still exists, after starting the engine for the first time since changing the head gasket, 5 litres of oil has transferred itself from the sump into the water system within 5 minutes at idle. The expansion bottle is now full of nice fresh oil. I have not seen any sign of water in the oil.
Someone has suggested to me that the divide between the oil and water sections of the radiator may have failed and that is how the oil is getting into the water system. The radiator is new but not an OEM, it's a bit plasticy actually...
Has anyone known of this before or can suggest what the problem is?
