When I am sure there are no more leaks I am going to put grease around the collars of all the exposed pipe fittings as this problem has been caused purely by corrosion from exposure to water coming from the wheels. I will top up and bleed the system through the week. I fitted the new pipe with a bit of instant gasket just to be on the safe side and pushed the clips back on. You can see the state of the connector here. I then used a screwdriver to release the retaining spring and pulled the higher end out first. This now exposes the other end of the pipe. I then took the plastic wheel arch liners out. I decided not to drain the system and hoped I would not lose too much coolant. Jacked up, wheel off and a basin to catch the coolant. So I eventually got round to doing this job today. I don't think I have put a litre of coolant in, but it has been on my mind to get it done incase it got any worse this year. I figure my next step is to re-test compression and leak-down on a warm engine and see if my results are any different.I have had a small leak for about a year now from the lower of the 2 coolant pipes in the left wheel arch. Seems like the coolant system is getting over-pressurized, which I'd think would be caused by a cracked head or a faulty head gasket, but those should also show some level of intermix or different leak-down results. I've run it pretty hard to see if I can un-stick them, but I haven't re-tested. Based on compression and leakdown tests, and the fact that it had been sitting for two years, makes me think that maybe I had stuck rings.Nothing from the coolant tank or exhaust. Could hear air leaking out the oil fill tube only. Leakdown test results were pretty poor - most cylinders were around 50%.This was done on a cold motor - I need to re-do it when it's warm Compression test had odd results: One cylinder was at 170#, the rest were lower (#100) but fairly consistent.I think I have the air out but even if there was an air pocket it shouldn't forcibly expel several liters of coolant in a few minutes. I pulled the pressure release valve and refilled, drove around and refilled, etc. The spark plugs looked fine, all were consistent in color.Engine codes are related to running lean (assume MAF needs cleaning/replacing).There's some odd RPM surging that I think it related to the MAF. Generally speaking, the car seems to perform just fine.I replaced the valve which didn't make a difference. It appears that the leak is coming from the pressure relief valve, not the tank cap. I installed a new coolant expansion tank (old one cracked) and the updated ("-04") cap. This happens as soon as the system gets pressurized. Sometimes a trickle, other times it's just pouring out. Issue: It's forcibly spewing coolant out the overflow tube at a very rapid rate. The previous owner then let it sit for two years because they weren't sure what to do next. That would seem to possibly indicate a bad head/head gasket. A local independent shop did the test for hydrocarbons in the coolant, which came back positive ("bad"). They had the water pump replaced, but it happened again. The previous owner had an issue with overheating. I'm working through an issue with my new-to-me 2000 Porsche Boxster S and I'm wondering if y'all can assist with troubleshooting.
