Tech / General EngineIs your car making a strange sound or won't start? Thinking of adding power with a new combination? Need other technical information or engine specific advice? Don't see another board for your problem? Post it here!
Drove over a burly metal object sticking out of the ground...long story... tried to clear it using some 2x4's, to no avail. It lightly scraped the k-member, smacked hard into the oil pan, scraped into a plastic cover right behind the oil pan (does anyone know what is under this plastic cover?) and then finally smacked hard into the transmission oil pan. Surprisingly no penetrations or leaks! however I'm now hearing a rattle/knock noise that started immediately after the collision, like metal clanking together while the engine is running... sorta of like DA-DA-DA-DA-DA that is sync'd up with the V8 exhaust rumble. I thought at first that I knocked the transmission mount loose and it was just vibrating against the body, but once I got under the car with it running I found nothing of the sort.
The noise appears to be coming from the engine, or between engine and transmission. I put my hand against the plastic cover that is right behind the oil pan and I could feel a prominent "thump" every time the rattle/knock occurred.
Was wondering if anyone could tell me what is causing the rattle/knocking sound. I'm thinking the impact could have squeezed some parts closer together and now they are rubbing and making the noise from the natural vibration of the engine.
I'm more curious about what's causing the noise than interested in fixing it. As some of you know I have an LS swap on the horizon. So it's adios to all this old tech. Car still runs, car still moves.
My crystal ball says 'Outlook Unclear', with a 60% chance of driving offroad like the Duke Boys catastrophically murdered the magical Goldberg unit that converts petrol into forward momentum. But that ol crystal ball tends to jump to conclusions and always assumes the worst.
Wait, you don't know what an inspection cover is hiding, but you're planning an LS swap? I'm no brain surgeon, but I've read a few issues of Golf Digest. Good to Go.
I'd bet the oil pan spot welds broke up front of the pan and the metal windage tray is being hit by the crank counter weights/rods. Seen that a bunch.
The plastic dust cover over the flexplate and tq converter mostlikely won't be the problem.

No way man, Rubbermaid can make a garbage can that takes a lickin' and keeps on tickin' but you bump that plastic cover and all the magical fairy dust hiding within gets out and you pick up a rod knock.
I just assume... My crystal ball, assumes... that any story that starts/contains/ends with "I was offroad in my thirdgen and got my car hung up on a steel fence post, and now I have an engine knock" includes other details like "I was going 90mph across a freshly plowed field while stuck in 2nd gear with a farmer on an ATV chasing me with a shotgun" levels of absurdity. The 'jump to a conclusion that fits the known "facts" machine' automatically assumes there's more to the story and that "metal clanking together while the engine is running" is describing the result of beating mercilessly on the car, rather than getting something hung up on the oil pan.
I'm paraphrasing, and going with the simplest explanation that fits the 'facts' here, so apologies if I'm my crystal ball is just being an a-hole...
Yep skrood the pooch trying to pull her out of storage from backyard. took a few attempts to get over that damn metal collar. So can see how some of you think I was offroading dukes of hazzard style but na just panicked trying to get the damn thing to the street. On a tight moving schedule. Cars being shipped to its new home where i'll have a couple years to get it swapped. Its not my primary driver. Im a 'backyard mechanic' that's seen one too many youtube vids and will be relying on some expertise from the ls swap section etc.

See that sounds reasonable.
