Cheap but not low quality from the looks of it.At least he is filling his parts cannon with cheap bullets...
I ALWAYS keep one important rule in mind when diagnosing cars; never assume it's only one failure. Cars are complex and coincidences happen often.Wow. Unusual.Glad you found the issue. Sounds like you had a coincidental action. Put High Octane gas in and next start the timing gear slips.
I've seen that before. I once pulled a spark plug to see how my 2.2 Turbo was running and the timing belt tensioner decided to slip as I tried to start it a moment later. Had me stumped for a couple of days. Crank and no start.
Also had another one something like that. It was a ring gear on a flywheel that twisted just enough to rub the case and make a gawd awe-full knocking racket. Thought I had spun a bearing. $100 for a fly wheel and and engine/trans re-and-re and it was fixed. Also happened on a re-start after adjusting a couple of things up top on the engine.
Coincidental timing ( pun intended )
My guess is you probably put the lowest octane gasoline. Premium doesn't cause the engine to knock, It's the opposite. You're better off with the 91 octane as it's better for your engine. It's all I've used on my cars, never the lower octane. one time my wife put the lowest grade and then the engine started pinging (not knocking) acceleration.Hi, I have a MK2 Supra (1985) and I might have made a mistake. So long story short, I was going about my day and went to go and fill my tank up. Well I guess I must’ve used premium because I have an engine knock. I’m worried about what to do and if there’s anything I can do. Please help I don’t want to loose this car over something so stupid like this. Thank you anything helps! Video attached.

I live in central AZ and have Ethanol-free 87 available year-round. I think it's the market i'm in though, as a ton of older cars, motorcycles, and even farm equipment have been putting around since the beginning of time. I fill my gas cans with it as it's much more stable (less hygroscopic) than blended. Technically can get about 5% more power out of an engine with the same a/f, but i live at altitude so that point is basically moot.You guys up north are lucky, we have to search for non-ethanol stations here! A few carry it, but most don't. Old bikes hate ethanol, as well as most gas-powered equipment (lawn mowers, tractors pressure washers, etc.), it eats up the rubber hoses quickly and the fuel turns green inside the carb bowls pretty damned quick. I have to fill 5 gallon cans so I can run my dirt bikes/quad/pressure washer/ride-on mower about twice a month.
