Why does a car make noises when you put in the reverse gear and its still rolling forward (manual shift)?
Reverse is is the only gear that slides into mesh with another gear and if the car is moving so is that gear. Like trying to poke a stick into a fence as you walk along, lots of clatter but the movement prevents engagement.An automatic will make the same noise for the same reason if you put it in park while moving.
Does a blown head gasket cause the engine of a car to make a knocking sound when you step on the gas?
Every modern car has the head gasket but they vary in their thickness and construction based on the manufacturer’s design of the engine. The head gasket seals the combustion chamber allowing your car to build the proper compression and contain exhaust gases. The head gasket also keeps coolant and oil out of the combustion chamber which is very important.How to know if the head gasket is blown ?If the head gasket is blown, it can cause an engine to knock but will usually be a mechanical knock and depends on how the gasket blew. If the engine has been stood for a while both valves will be closed and any pressure in the cylinder would be dissipated. A reliable way to determine whether a head gasket is blown is to test for carbon dioxide. In this test, the coolant is examined for traces of combustion gases. The test is performed with a tool that utilizes a solution that changes color upon contact with carbon monoxide.What are the symptoms of blown head gasket ?One of the major blown head gasket symptoms is a consistently high temperature of the car engine. It can be checked from the temperature gauge of the car dashboard. Chronic engine may be both a cause and symptom of a leaking head gasket. Apart from this, other symptoms of blown head gasket are:· Significant drop in coolant level· Mixing of Coolant and Engine oil· White smoke from Exhaust Pipe· Popping of coolant overflow tank capThese are some of the symptoms of blown head gasket.

How do you fix squeaky shocks?
Sometimes it's the shock itself that is squeaking, sometimes the spring mounts, sometimes the shock mounts, and often one of the 18 or so rubber bushings between the metal suspension parts. Or a bad ball joint. Or a combination of the above. What you do is take off the wheel and take a bright flashlight and inspect everything. Look at every place a bolt goes through a rubber bushing. If the rubber has the slightest surface cracking, or has pulled away from the metal parts, or if there is orange dust on the rubber or metal parts, then the bushing is probably bad and needs to be replaced. Look at the shock. If there is oil on the shock, it's leaking, and that can go on for years before it causes squeaking, or maybe it started years ago and now it's squeaking. You can press on the car and try to pin down the source of the squeaking, but the sounds are often misleading. I go mainly by looking for rust dust, cracks in rubber bushings, and oil drips from the struts. The bushings are about $20 each, but require $100 in labor to replace. Sometimes it's cheaper to replace a whole control arm for $180, as you get a new arm and two new bushings, that only take 15 minutes to replace. Struts cost $100 to $400 in parts each, plus an hour of labor to replace. It's often best to replace both sides even if only one side squeaks now, as it's a little bit cheaper to do both now than to wait two months till the other side does the same thing.
