The oil should be pumped into the oil journals in a second or two. If you still have rod knocking, you still have problems. It could be piston slap or any of a number of problems, but rod knocking is most common. Have you checked your oil pressure? If oil pressure is up when the engine is running and the knocking continues, it's not a crankshaft problem.

But seriously a knocking as opposed to a clicking would point toward a bad crankshaft bearing.
NO - see your mechanic .
this sounds like the big end bearings in engine are worn.this is an expensive repair,depending on how long the knocking has been knocking and whether the crankshaft has been damaged enought to need a new crankshaft.
It's the spirit of the car knocking on the side saying "HELLO??? TAKE ME TO A MECHANIC!"
extreme cold temperatures might cause Mazda rf diesil to make knocking sound , however; it is recommended that you get it checked from the mechanic.
possibly distributor. tow to mechanic . if you drive , you could damage your engine.
The bearings on the crankshaft are worn out. A complete engine overhaul is needed.
If they are hydraulic they need to be pumped in oil first.
Have the timing checked and adjusted by a mechanic. you may have to replace the lifter valves if they are getting stuck
you probably threw a rod out, get it to a mechanic ASAP or you will have more problems.
A mosquito but i cant be sure because i am not a mechanic
you go to a mechanic and change*
changed camshaft and crankshaft sensors in 2005 toyota tacoma 6 clyinder and now it wont start any idea what to try next
Check to see if the wiring is damaged.
Yes, there's a special tool that is inserted into the crankshaft during this procedure. See http://www.etoolcart.com/browseproducts/Ford-Cam-Positioning-Crankshaft-TDC-Timing-Pin.HTML If he forgot to remove the tool before he started the engine, it will do damage to the crankshaft.
your shocks or your brake pads are probly loose. You need to check them out. If that's not it then take it to a mechanic.
Sounds like your piston or rod. Please see a mechanic for a diagnosis and what it will cost before having the work done.
I would recommend taking it to a mechanic and have them listen to it. Everyone's definition of "knocking" is slightly different. Try not to drive it for too long; engine knocks can usually cause pretty severe damage to an engine.
You will need a tool called a puller to remove your crankshaft on your Nissan Xterra. You can purchase this toll at most auto parts stores, or borrow one from a shop or another mechanic.
It's hard to prove fault in these cases but the timing belt change requires removing the crankshaft pulley. So the mechanic would have had to have at least seen its condition. More likely, he damaged the pulley in the process of replacing the timing belt. Maybe he used an impact wrench when he reinstalled it and the key wasn't aligned correctly?
Engine knocking occurs in a vehicle when there are misfires in the spark plug ignition causing an air/fuel mixture to explode outside the envelope of the normal combustion front. This condition could be very damaging to an engine if not checked by a mechanic.
AFAIK no, you just need to do the crankshaft variation learn. If you don't have a scan tool with the required functionality, you will have to visit a mechanic.
It's fairly complicated. The sensor is located near the bottom to the engine behind the crankshaft pulley and timing belt cover. Not a job for an inexperienced do-it yourself mechanic.
