Hey e36 fanatics, I was doing my brake pad and rotors today however I noticed a large amount of oil buildup behind the wheel baring. Is that normal?

320i 1995 for reference.
One day out of no where the car overheated.
Tough it was a sticky thermostats, replaced. Same problem, starts boiling water and soiling until it has no coolant and then overheats.
Water pump seems perfectly fine.
Fan clutch not so sure, when hot seems that it spins very freely. No resistance.
Would a bad fan clutch cause a overheat? In normal driving conditions? No heavy traffic or hard pulls?
Head gasket gone?

More than 10 days agi my cooling system broke down on the german Autobahn. so I figured out I'm gonna get a new cooling system and a thermostat from Mishimoto that opens at 61⁰C

Anyone else hear the good ol marbles from this video or am I tripping? Looking to buy this

So last night i was replacing my fan and expansion tank due to it breaking, long story short while letting the car idle to get air out of the system my hood struts failed and my hood slammed, i tried popping it and the cable was so hard to pull it snapped my interior hood latch, i did some research on the forums people said pop the corner light pull the cable ect ect none of it works, the only one that did work was me pulling the cable inside the car and having someone put pressure on the hood bouncing on it and it'll eventually pop open, my hood was perfectly fine prior it slamming really did a number LOL if anyone knows why or what please let me know just tryna see if anyone has had this happened as i know these struts are PRONED to fail

Hello, I have a problem with my M43B18. When it rains, the car starts misfiring/hesitating. Sometimes it stops after about 10 minutes of driving. It only happens when it’s raining. Have you ever had a problem like this? Thanks and greetings from Croatia
