It was supposed to be a cheap classic I could gradually do up - now it's looking like a money pit.
When I went to see it, I checked for mayo and found none, but a couple of things have arisen as I've been servicing it.
First I took almost 7l of oil out of my m20 (320i touring). It was a very dark brown/black, not milky as I think of milky, but not very clear either. Oil in the filter looked same, very old but ok.
There's still no mayo on the filler cap. It still performs well, idles well, no overheating (just above 1/4 on the guage up to just under 1/2). Oil looks fine after 20 miles or so.
Second, the coolant expansion tank is grubby inside, but not sludgy, more like a bit of rust on the surfaces. I think rad seal has been used at some point which might account for it. It's very hard to see the level from the outside, but the coolant looks alright when you look in the sensor hole - though it's mostly new stuff I've added (about four pints).
the 7l didn't bother me much at first - just dumb overfilling, I thought - but now It looks like coolent leak internally. Just wasn't very milky, which is what I'd expect.
I'm getting prices for a cam belt and water pump, but if the head gasket's gone it might be time to say goodbye sell it as a spares-runner with mot til May.
What do you reckon? how can I cheaply find out where I stand?
