Rules

This is a community for asking Mechanical questions pertaining to vehicles, engines, etc. If it’s got wheels, treads, floats, flies, or has an engine you’re good to go and we’ll do our best to help. Title, salvage, body work, paint work, etc questions also do not belong here. Memes, videos and other non-questions are not allowed.
No intentionally bad, harmful, or deceptive advice. If we feel a piece of advice is particularly reckless, dangerous, or extremely unhelpful it may be removed. Please report bad advice to the mods.
Keep discussion friendly, civil, courteous, and professional. We’re here to help so being rude won’t help. Don’t assume a shop is trying to “rip you off.” It’s okay to ask for a second opinion.
Only one vehicle/problem/incident per thread, and only post once. The only exception is for posting updates, provided it is properly marked as an [Update] or similar.
Body Work. Questions related to dings, dents, accidents, paint and so forth DO NOT belong here. Take the car to an auto body repair shop who can give you a qualified estimate.

IMPORTANT

Understand that the assistance you receive is ADVICE ONLY and is given with the understanding that the giver assumes no liability for any damages that occur as a direct or indirect result. It is impossible for a mechanic to diagnose your problem accurately without seeing/hearing the problem with his own senses. Any advice you receive you must use AT YOUR OWN RISK.
