Have you changed your engine oil to a thicker grade for cold weather? Try 20/50 engine oil.

Engine got a knocking cold start, silint when hot

It has developed a clicking engine noise on a cold start. After the car has warmed up, the sound goes away. ... Clicking or a sharp tapping from the valve cover on top of the engine would point to a valve train noise. A dull tapping or slapping sound from the side of the engine block would point more toward piston slap.4 Nov 2011

Cold-start engine clicking is a nuisance, not a disaster -

What will be the problem if i have a taping noise when i start my car until it gets warm mitsubishi 380

A tapping noise that starts out cold and goes away when warm is usually caused by a valve lifter inside the engine. The lifter may be worn/leaking down and will be noisy until it fills with oil pressure. You can try an oil additive ( Lucas Oil Additive ) available at most part stores works very well with noisy lifters. Another noise that can happen cold and go away when warm is an exhaust manifold leak. However, this is normally a ticking type sound rather than a tapping sound.

When I started it up it made a lot of noise. Is it possible I could have bent the valves.

Bent valve noise doesn't go away. If it clatters when you start it and goes away( most of the time) after a few seconds. You are low on oil and just put more in it when cold.

Tapping in bottom for a few seconds then stops motor run good tapping stop i had my oil change also went back and change it again

these engines have hydraulic lifters that open the valves,when you start the engine it doesnt have oil in the top and will tapp for a few seconds it is totaly normal for an older car, make sure you use a napa gold oil filter they filter the best and have an anti siphon valve inside that keeps oil in the top of your engine for cold starts also try some marvel mystery oil its the best, will clean and quiet

I have a 2004 Toyota Tacoma. During the last 2 months when I start the truck in the morning I hear a "tac, tac, tac, tac ...." noise for 30s to 1 min than it stops when I drive away. This...

This is most likely a noisy lifter (or valve tappet). In cold weather, the clearances in the valve train open up because metal contracts due to the cold. Once the oil pressure comes up after start the noise goes away because the larger clearance fills with oil and the lifter becomes "cushioned" with the oil. The proper fix is to have the valves adjusted. I believe in your model, that is done by putting shims on the lifters. This will quiet the noisy lifters. In the short term, you can try using a lighter weight oil for cold weather. This will get the oil to the lifters faster after start up and quiet the tapping more quickly. Once the weather warms again, shift back to the normal weight.

Smokes when starting cold engine. Goes away in afew seconds. Does not appear to be burning oil.Not sure if this is a problem with rings or seals on valves.

valve guide wear causes this. It's not a big issue, but if you ever have the heads off, have the guides replaced or knurled.
