Rinze Posted September 4, 2020 Report Share Posted September 4, 2020 Hi, First a little context: I bought myself a little project. Is a 2003 V70 2.4 engine:B5244S Previous owner had top radiator hose blown off and told me it's using coolant by the liter. His garage took a quick look and said probably the head gasket blew. I did a short diagnose and found low compression on all cylinders. Also it builds pressure in the coolant reservoir as soon as the car was started. Since the oil looked like chocolate milk I didn't want to run the car to much and started taking the head off. What I found is best told in the pictures below. The oil contains water as can be seen in the picture. My question is mainly what do you guys think about those cylinder walls? Are those scars from coolant? I can lighly feel them with my nails when scratching the cylinder wall. Can those be cleaned out with some scoth-brite green or is this really bad? Besides that, how likely is it that this motor has other damage? Thinking about rod bearings because of the water mixing with the oil. The motor only ran for a short while with the leak afaik and sounded normal with no low pressure light. Before I get the head checked for cracks I would like to know if this engine is still worth it.

Ihatespeedbumps Posted September 8, 2020 Report Share Posted September 8, 2020 I wouldn't clean them with anything. I've seen worse on engines that ran just fine. Link to comment Share on other sites More sharing options...
