This is the E30 my friend bought. We were totally off thinking it might be a stuck lifter. Turns out it was rod knock. How do we know? He was driving it back from his mechanics place, who told him in no uncertain terms “that engine is dead, don’t even bother trying to fix it”. And then it went bang on the way home. How bad? Half of one of be spark plugs is gone forever, and the other half was just chilling in the engine bay, after hitting the hood and leaving a mark on the insulation. So losing a piston on an engine with 418k kms means that it’s getting a new engine. Luckily the car was only like $1400, which is a pretty sweet deal for a Mauritius blue vert. More to come as it is slowly resurrected.....
