I’m about to dive into the vacuum leak/hose replacement hole.
Quick question on a test I ran. The round canister on the left tested that it holds vacuum tight. The one on the right (supplies the bank of vacuum solenoids), when pumped to 10in hg, leaked empty over course of 4-5 minutes. Is this normal? Does such leakage constitute a vacuum leak in an of itself that can show up in engine performance issues?
