On the way home from work, going WOT in 3rd gear, all of a sudden I get a huge burst of acceleration. Glance at the boost gauge, and I'm at 14psi (shocked) :wtf: and hear F'ING LOUD pinging...I'm at stock boost remember...I IMMEDIATELY get off the gas and pull over. Rev the engine a few times up to 3 or 4K..seems fine. I pop the hood, and look to find a nice crack in the vacuum hose.
I replaced most of that hose a couple of months ago when it cracked before and I boosted up around the same level. I left a couple of inches attached to the wastegate actuator because it is a PITA getting to that connection.
So I'm thinking s*** I just ******* blew my motor. I slice off the part of the vacuum hose with the crack, and reconnect the new hose to it. Check the gauge, no vacuum leaks. I rev up the engine gradually to 3K, then 4K, then 5K...everything sounds fine..no weird noises...sounds perfectly normal. I pull away, keep it out of boost but allow the engine to rev up fairly high, everything's still fine. I get on it a little more, and finally after 10 minutes or so I go WOT again all the way to about 5.5K....and thank GOD everything was fine.
I took the car out again just now, and it still is fine. No weird sounds, no loss in power, no fluid loss...THANK GOD
What suprised me was the fact that I didn't hit fuel cut.
So people running an FCD beware...pinging can happen even before the stock fuel cut kicks in.
It only pinged for a tiny fraction of a second, so I think I was spared. Didn't throw the 'Random Multiple Misfires' CEL (actually no CEL at all which is a good thing).
