I bought a 1986 535i with a “ran recently” engine.

I brought it home, changed oil, oil filter, coolant, spark plugs, and spark plug wires. I cranked the engine and coolant came out the exhaust.

I did a coolant compression test and brought compression to 10psi and saw the pool of coolant growing in the cylinder. I wasn’t able to see where it was leaking in from.

Borescope in the cylinders showed pools of coolant. Compression test came out with 127, 73, 75, 85, 95, 115.

ChatGPT is suggesting I inspect the intake manifold.

I’m pretty new to engine work, but can to most maintenance. People who actually know engines, what else should I actually look at or just replace?

Thank you for your time.
