Honda VTEC Engine Knocking Lets Tear it Down
https://twitter.com/bullshitkorner https://www.facebook.com/pages/Bullshitkorner/415124691917952 My neighbour had swapped out a Honda VTEC engine that was knocking and he was just gonna scrap it but decided to give it to me and see if i wanted to strip it down and see what was causing the issue. The crankshaft looked like it spun a bearing and it welded itself to the crank while tearing itself to pieces. this engine was quite easily rebuildable but i scrapped it and purchased booze instead.

Starting a 1998 Honda civic that has a severe rod knock.

Is this a bad tensioner sound?
I've had this car for about 7 months or so. I've had this sound secondary sound start coming from my engine. Anyone know what it might be?

H22a4 Bent Exhaust Valves
"The Incident" Just to clear up a few misconceptions, this is the sound of cylinder #2 bent Exhaust and intake valves. Not rod bearings, rod knock, or anything else. I paid to have the head rebuilt with all new valves, seats, springs, and retainers. It sounds the way it does because a piece of a broken drill bit wedged itself in between my Exhaust valves and seat. It runs perfect now and I've put 13,000 miles on it since.
