Mate.Before you let ANYONE pull the engine apart,get the timing checked.I am only going on your description but it sound like the motor is "knocking".It means the timing is wrong and is a cheap fix.Hope this helps

I hear a knocking sound when ever I start my engine


check oil level if low add oil ---if oil milky in color like chocolate milk possible internal damage from --blown head gasket-damaged head --the knock from engine usually means that damage to a piston rod has occurred [rod knock] and knock usually doesnt throw an engine code and usually fatal to engine will need a mechanic to diagnose how bad or what extent the noise is with engine

I have a 1997 2.5 jeep wrangler.when you first start the engine it runs and sounds fine, then after about 20 seconds it begins to have a knocking sound only at idle. when you press the gas you cant hear...


It may be piston slap. This is caused by either engine wear with the piston bores being too large for the pistons, or by poor manufacturing tolerances, or a combination of both.

To test for this, start the engine up first thing in the morning and run it for about thirty seconds while you listen carefully and memorise the sound and intensity. Turn the engine off quickly, remove the spark plugs and put two squirts of motor oil into each cylinder. Reinstall the plugs, start the engine up again and listen. If you have piston slap the noise will have been greatly reduced or even eliminated for about thirty seconds seconds and then returns.

The fix is to rebuild or replace the engine, but if it works just fine then don't worry. Many slappy engines keep going for tens of thousands more mile. The fact that your knocking is only at idle suggests your crankshaft is not to blame.

My 91 honda civic has a problem starting sometimes. It starts in the morning. Sometimes it will not start on a hot day and it will just shut off while driving occaisionally. Often it must cool off before...


It will be the main relay. It is a massive fuse under the coin tray. The joints become dry and need re-soldered. A very common problem on these cars.

The clunk is the starter engaging the flywheel, check that it is properly seated, a bolt might have come loose.

Some times it has a loud knoking when you start it up! oil presure good.


If this sound only happens when you first start it in the morning, and then goes away, then you are experiencing either lifter ticking, or piston slap. These both are fairly normal for this vehicle when it's getting higher in the miles, and before the oil gets to all the parts. Once you shut the engine off, the oil drains down, and it has to recirculate some of it. This takes a couple of seconds sometimes, and you hear this knocking sound when it happens, especially if it's cold out, or you are using thicker oil than recommended.
If the knocking sound continues after the vehicle has been running, then you need to have someone check it out for sure, because you could have a connecting rod knocking. This means that your engine is about to go, and you should not drive it.

Knocking noise in 3.8 lit 95 ford taurus


You can not put a liquid where metal is supposed to be. Just a general rule of thumb. The high RPM's had been too much for the engine, and A rod bearing, or rod knocking is about the same thing. Dont try the heavier oil thing, I hate when ppl suggest such stuff. Just replace the bearing, or in most cases and cost efficent, the engine.
