Question about 2001 Chevrolet Blazer

1 Answer

When it's colder outside and I start my Blazer, there is a constant ticking noise that comes from the engine area. Once the truck warms up, the ticking goes away (after 5 minutes or so) but when you press the gas pedal, the speed of the noise gets faster. I went to have this checked about a year ago and I was told it could be the lifters, but they said that's something that can't be fixed. Does this sound like anything familiar to anyone? The clicking goes away, like I said, but something can't be right if it makes the noise. When it's warm, it doesn't make any noise at all, so if anyone has any suggestions/help, I would greatly appreciate it.

SOURCE: Lifter ticking when I start my 1999 Chevy Tahoe

Your lifters have become clogged over the years. Its only after the oil warms up and thins out does it allow oil to "pump up" the lifters. That's why it goes quiet after 5 min. There are several different brands of additives on the market that can fix this problem ,unless you have a more serious mechanical problem, which I doubt.Check your local auto parts store for the additive. Just add it to your oil and "wham!" problem solved. Good Luck!

Does it do it when cold or every time you start it? if it does it every time then I would pull the valve cover off of that side and see if there is a loose rocker nut, if notthen you have a lifter going bad, or has carbon sticking in it.

ticking noise usually but not always is from the head--valves-usually a rocker arm starved for oil or bent clogged push rod check oil if black and thin can cause tick also extreme cold can cause -because oil thickened sometimes goes away when warmed up-same noise /check oil pressure extreme problem oil pump failing or clogging --timing belt can cause a ticking but they usually fail-- break causing major problem ----other area to check are the pulleys and bearings in witch the belt rolls on-- alternator can also cause a tick when bearing is failing --

Loud ticking noise when first staring, engine stalls sometimes when starting it unless I hold the gas pedal down


The TPS would be what I would do had that problem once myself solved the problem. as for the ticking noise sounds like a lifter is bleeding down as long as the noise goes away you will be ok. But may I suggest that if you are going to keep the vehicle for awhile longer you might want to have a set of lifters put in it.

Pound ticking noise when my 99 durango starts goes away after the engine warms up


The ticking noise could be a faulty hydrulic valve lifter. When last was the oil & filter changed, it coul be that the oil is thick and not going through to the lifters and when it warms up the oil is thin. It could be that the engine is need of an overhaul as 148.000 miles is 238.182 Kilometers and that is a hi milage.

Tapping/ticking noise when rpm goes above 2000 with check oil warning on my chevrolet lumina ls 2005 model


You will have to take an oil pressure reading and compare to specifications. It could be that the pick up screen is plugged. Do not drive the car as damage to engine will occur.

I havent run my car in awhile and I noticed that when I start the car and after its starts warming up it has a ticking noise when it is idoling. I figured its the lifters cause it hasnt been started all...


If the ticking is a constant ticking, it is most likely the lifters. The lifters in these engines are hydraulic and and must pump up with the oil pressure. Once the oil warms up and become thinner, the ticking will become constant due to the lower hydraulic pressure of the thinned out oil. As far as the moisture from the exhaust, this is also normal of a vehicle that has not been started in a long time as the condensation that builds up in the exhaust system must heat up to a point where all of the moisture burns off. The longer it sits, the more moisture will build up in the system requiring longer times to burn off. If after a few days of running the moisture does not burn off then I would get it checked out by a certified mechanic.

Try using a lighter weight oil as the temperature gets colder outside the oil becomes thicker and takes more time for the more defeat the oil so that it may and pump up into the valves and etc most vehicles will tick until the oil warms and will go away ....also a higher grade of gas will also help
