SOURCE: no compression in one cylinder

Timing belt slipped around cam pulley. Take off your timing belt cover and check the position. This would explain misfiring and compression loss. Stretched belt or missing cogs in belt likely culprit.

My car makes tapping noises when you start it goes a few blocks then stops running wait a while start it up and it does it again

Noise from the top or bottom. Top end doesn't usually kill the engine, but the bottom end noise will. Year make and model helps. If it is old and high miles. Time for another engine if it is worth it.

Noise in engine sound like it is coming from top engine when raving it up ratteling noise. Engine runs fine

Noise could be lack of oil or wrong grade of gasoline.
Check your oil level.
If the noise is worse when the engine is working harder, like going up a hill, you should try higher grade of fuel, like premium.
Hope this helps.

New head changed; lot knoking noise on top of engine coming up, may be the time chain problem?

90psi compression is low in some cases engine may run but will be very weak and stall after a short time. a good petrol car compression should be between 120 to 150psi.
Does the engine oil light turn off after started, make sure u have oil pump up to the head, check the oil pick up inside the sum. The engine valves should not and never bend from no reason.

Cylinder compression; i like to know if with 90 psi at all cylinders is OK

from finding on the list 93 psi is recommended but taking into account the age and milage of the engine it would coming as good. means the parts are wearing at the same time i.e valves and piston rings. if you wanted to make it higher psi you could clean and regrind the valves and change the piston rings but it would be a waste of time as it is only 3 psi out. maybe give engine an oil change this can bump up the psi in an engine. use a slightly higher oil rating. as engine is old now and it will keep running for a longer time.

you need to be more clear,
top right of body, top right of engine, transmission, axle?
noises are 99% not good, and not safe, do not delay find a competent
hands on ASE mechanic to look at car, even pay for Diagnosis only !
if the engine makes noise you do need to flat out say that.

there are tricks, to do that, but do not drive any engine that makes noise or invite total engine destruction. can be.
i can be . bad mounted accessories loose or just bad.
loose exh header clamp banging about (or gasket there)
or cam chain getting ready to lunch the engine. i have 2004 v6. can advise better. but you need to be clear.
you can drop belts off to see if noise stops, for 2min dead cold block.
you can pry exh parts to see of noise abates.
you can use a $5 HF stethoscope to listen to all parts, and hear if they are bad. so easy. good luck to you.

Timing Chain Failure - Can there ever be a case where there has been no permanent damage to the head.

You may be in luck! your engine may have a squash plate on the heads. This will keep the valves bending. Put the new chain on it-MAKE SURE THE TIMING MARKS LINE UP! Then do a compression test to be sure. I've had a timing belt break at 10 miles over the "suggested " change mileage, and that plate save the day.
