on the way into work this morning I noticed if I accelerate quickly I get a large amount of steam out of the exhaust. I replace the water pump ~ 3 months ago (no serious overheating though). I've had to top the coolant up a little bit now and then for as long as I can remember (2 years+), so this may not be a new issue. I think the first thing I should do is a cylinder compression test to check the rings are ok.
Any other suspects other than the head gasket ?
