Anyway I had some more 5W40 turn up yesterday and got around to topping her up this evening. She then started up just as she always does and the engine sounded sweet as a nut as it always does, but now she's sounding a little more muffled than usual at the back end... Almost as if the baffles in the exhaust are going.
There's also a noticable amount of white smoke/steam coming out the exhaust as well

For about a week before the oil light flicker she had been smoking/steaming first thing in the mornings on my way to work, but again I just assumed it was moisture.
The head gaskets on H22 are generally quite good aren't they, but could this be a possibility or is the a more likely story? When I thought I just had an oil leak I suspected the cam oil seal or maybe even the vtec solenoid gasket, and there looked to be damp oil just about the gearbox, so I've cleaned that off to then keep an eye on it. But I'm just worried now what with having a head gasket go on my old Rallye, or am I just thinking the worst?
