Altogether car  may be dealing with a cam chain tensioner that is loosing oil pressure when the car is standing. A loose cam belt tensioner can increase the noise . Get the oil pressure checked.Also check the timing chain.If its over stretched it may make noise while starting.
Also check the starter and its connections to battery.Also the alternator belt.

Check out this.Thanks,.

The 3.4L engine has special pistons that are designed to expand as the engine heats up. When the engine is cold, the pistons make a knocking sound that resembles lifter noise or piston slap. As long as the noise goes away after the engine warms up, don't sweat it; this is normal.

A knocking that starts when engine is cranked then it goes away


The knock is likely a worn connecting rod bearing. Are you using the correct weight of oil, never use any heavier than 10W30W, heavy oil viscosity's cause slow circulation through the oil passages and starve the engine's bearings for oil.

'96 VW Golf GL with 2.0 motor. Cold start knock


It sounds like the hydraulic lifters are bleeding down after sitting for a while... there are ball checks which are supposed to prevent this... Try using a good engine flush (a product that frees sticky lifters) and replace the oil with a good synthetic... Hope this helps...;-)

ThenI start my engine it sounds like diesel and no power


how is the oil level and pressure?, how many miles on engine? is this a loud knock or rather a clatter/ticking noise? knock is engine rod or crankshaft bearings, clatter loud ticking is valve follower noise. how long before it (the noise) goes away?

Knocking when first start engine


Depending on the period of time and intensity of the knock ? If it is a rapid short ,loud knock then disappears altogether you may be dealing with a cam chain tensioner that is loosing oil pressure when the car is standing. A loose cambelt tensioner can increase the noise .
