It seems whenever you get a handle on a Rover something new pops up but I should know this by now. A little background on my Rover - 02' DII with 155k miles. I am running an inline 180 degree thermostat. Headgaskets done 30k ago. Expansion tank cap replaced a few months back. No signs of coolant in the oil. Do have an intermittent tick when warm which I haven't been able to is a larger exhaust leak (all manifold and downpipe nuts/bolts are tight) or possible slipped liner. No burning coolant smells. No coolant smell or smoke out the exhaust. Have been chasing a few minor coolant leaks over the past few months including the throttle body heater plate to some hose clamps that needed adjusting.
After a trip to the mountains last weekend I noticed the 'water rushing' noise behind the dash which I knew was air in the system. I had been tracking temps via my OBD dongle (this thing has been a great investment) and they never gotten above 190 during this period so that's some solace. The coolant was low with no obvious puddles or leaks at the time. I topped up, bled and resumed driving on Monday. When I did wake up Monday there was a dried area on the ground but I wasn't able to determine it was coolant. Took a 20 mile drive last night, showing no leaks and the coolant level was about where it should be during operation and when I returned home.. I woke up to a puddle in the driveway this morning, however I was able to determine it was coolant. It is located on the passenger side, between the tire and engine block.Does not seem to be coming from the expansion tank overflow tube. A quick look at hoses didn't seem to yield any obvious leaks either. There has been zero burning coolant smell throughout this ordeal. I'll slide under and have a look tonight but wanted to get initial thoughts - the fact it seems to be leaking after shutdown is a little odd to me. Any initial thoughts or suggestions would be appreciated
