You could try putting a good engine oil flush in, if the inside of the engine is really dirty you might have to flush it more than once.

Hi,

Your engine has hydraulic lifters and it sounds as though you need to use 5/30 viscosity motor oil. I don't know your location but if your winter temperatures get down into the teens or lower then this step should solve your problem. The manual recommends 10/30 but that viscosity doesn't cut it in the colder climes.

All the best

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.

New lifters stil make noice


Make sure you are using the correct weight of oil for your local temperature. Lifters will be noisy in cold weather if the oil is too heavy. Torque the rocker arms.

I had heads replaced on my 2004 Dodge team 1500 5.7 hemi due to valve and spring issue. Then lifters became very noisy so replaced those also. Truck runs ok but lifters are making noise at start up now...


the hydraulics will leak down after the engine has been stopped for a while . The noise on start up will be until the oil again fills the lifters. If it is getting really cold (under 32F of close to 0 c) then you may have to consider a lighter viscosity grade of engine oil (10w-20 or 15w -30) the manual will have the recommended viscosity of oil for cold areas or you can check with the oil catalogue at any auto parts store.

Why does the initial cold start on my2.5L 1996 subaruhave noisy hydraulic lifters


Noise lifters on a 2.5 engine of the first generation are an unusuak problem; these engines are known to have "piston slap", which can sound fairly similar to noisy lifters. I owned a Forester with those symptoms and drove the car for more than 3 years without doing anything about it. The only real cure would be an engine rebiuld, which is , in most cases, not worth the effort, especially since most of the "stricken" cars continue to work without any problems for a long time.

2001 Buick Lesabre lifters noisy


Have you tried flushing the engine crank case? You may have sludge clogging the valve lifter oil pressure ports. Get a can of Berrymans brand Chemtool, add it to a cold engine crankcase oil and run it for 5 miles or so, then change the oil and see if the noise level improves. Some tapping noise on cold start is normal and not a sign of any problem. If the noise goes away in my opinion I'd just do the flush of the system and then leave it alone.

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.

What is this noise? Is this noise clacking the lifters,fuel injec


I would go to an autoparts store, and purchase some Sea Foam. You can put it in your gas and your oil, and it should clear your sound up if its lifters. I used it, and it worked great for the lifters on my Dakota. They will make noise sometimes when its really cold. Try it out. Hope it helps.
