B20Z knock? coming from cylinder 1
B20Z in my 94 integra, P75, fuel 45 PSI.
I recently had my brake booster develop a vacuum leak. I wasn't able to replace it for a month. By the time I had replaced it, I noticed a slightly high pitched ticking from 2k to 3k rpm.
Pulled the plugs, looked fine, going to do a compression check tomorrow.
Tried 93 octane but sound persisted.
What is causing this? Damaged internals from running with vacuum leak? Fuel? Maybe needs a lash adjustment? Help!
