Best Stuff to Quiet Lifters???

[truemetal411]

my motor has a bit of noise going on. im thinking its a lifter knock cuz it sounds very similar. ive used Lucas oil stabilizer to quiet lifters in the past, but it didnt work on this. anybody got some personal favorites or can recommend something?? ive heard Slick 50 and CD2 is pretty good. motors got 143k on her.

Rislone Engine Treatment

The Zetec Tappet looks like a bucket ,sets upside down on the valve stem , it's hollow no hydraulics pressure inside.There could be a clearance problem from a worn lobe , you would have to check clearance to find out . You may have an injector ticking , they get kind of loud with age .

[truemetal411]

idk if its an injector (actuially i didnt know injectors could be noisy) it sounds mechanical like a "clacking" noise

[dareall]

turning the key to the off position will quiet the car down.

or

you could check what johnp pointed out

[iceracer]

as John P said, we do not have hydraulic lifters. Junk addatives are a waste of money with the quality of todays oils.

Zetec engines are loud engines. Its possible you don't even have a problem

[truemetal411]

your not the first one to say that CT9A ive heard from many people these Zetecs are a bit noisy ( they vibrate quite a bit too ) idk im just gonna clean her out with some ATF or something (screw Motor Flush!!!) im a huge fan of SeaFoam so il try either that or some ATF in the oil. clean her right up!

il give that Rislone stuff a try maybe

If you use a big screw driver you can place your ear on the handle and touch it different parts of the motor and it works like a stethoscope. Like I said make sure its plenty long so your face isn't to close to get caught in fans or moving belts.

You could place it on the injectors etc.

As for a flush I prefer to drain a quart or two of oil out and refill with diesel and run at idle for around 5 mins. I have used it on every vehicle I have had and it really cleans it out. Some will argue it will remove good build up and cause leaks. I say if that is the case it needed to be replaced anyway and I have great success with it so thats my 2 cents.

ATF in the crankcase is a myth that died out decades ago.
Tell me EXACTLY what additives or composition ATF has that you want in the engine, and for what purpose.

Any flush or cleaning will make ticking LOUDER in our engines.
If you do want a safe and cheap flush, use Marvel Mystery Oill, and use a heavier engine oil to compensate for it, and bring the net viscosity up to normal. 1/2 qt to 1 qt is the right amount of MMO.

While we are on this topic. What were the good injectors again? For some reason I have something stuck in my head that they had 4 squirters where the old ones had 2. And what's the average life of injectors. Not to thread jack but it goes along with what's said.

I've heard ATF can quiet down lifter noise, and is an excellent pre-lube when rebuilding a motor.

[truemetal411]

ATF can be put into ANYTHING even to clean out a carb. you can even put a small amount in the fuel and itll lube the fuel system up. just not too much.

i just wanna put something in the motor that will shut it up for a while cuz i dont have the money to do any internal engine work as of right now (i still owe 900 on the car) this car is my pride and joy and i just want it to last.

I used to work at an Autozone. All of the knowledgeable mechanics used Chevron Techron. It really was completely unanimous among the good garages.

[iceracer]

I'm leary of putting ATF in anything except an automatic transmission or maybe power steering.
In the old days, kerosene was even used.
I have my doubts that any kind of flush will do anything to quiet the engine.
Flushes clean out sludge, which you shouldn't have in the first place as long as quality oil is used.
Once upon a time, oils didn't have detergents. Then detergent oils came out and engines were lost because the gunk all went into the pan and blocked the oil pickup. Of course I don't see that happenning today.
