Kreen Update

[JHZR2]

FYI I had put some kreen in my 91 318i last year to try to quiet a startup tick that I believe to be a hydraulic lifter.

I had only added maybe a pint, as I had some neutra in there already.

Since it is now winter (which is typically when the tick occurs), I figured Id try again.

Added a quart per the instructions.

I havent heard a tick yet, though it isnt really cold.

Im knocking on wood...

Good luck & let us know.

I thought with the lack of initial noise on a very cold start up that I was onto something. Unfortunately, multiple starts today in the mid 50s, indicate to me that the ticking noise is not gone. Sure perhaps we can argue that it will clean up in time, but at 150,000 miles and a failed earlier attempt, I think it is safe to say that I should take my chances and attempt to remove the cam, and then replaced the noisy lifter. If only I had time and it wasn't the winter...

I am ready to try this in my 200K 5.3L Tahoe to see what it can do with startup noise. I also picked up a 70's Mercruiser 140 I/O on it's last legs. If you remove the oil cap you can use the stream of air as a hair dryer. Maybe a piston soak will help that.

Now I can't decide what other product I want on the Promo deal.

Petersubaru: What Napa branch did you see Kreen at?

Get the kroil!! Its awesome. I was very bummed when I ran out...

I do have a question about ring soaking.

Did someone somewhere say that the Kano folks say to put the stuff in, REINSTALL the plugs and crank motor a bit?

Yet, folks here say to keep plugs out (to prevent hydro-lock, I assume). Wouldn't the Kreen just stay in a puddle part way up the piston?

The vertical 4 banger will be easy - pour and soak.
In a V motor, wouldn't agitation and compression force the Kreen all around and into the entire ring pack and heads more effectively?

I mean, If I read right, there should be a reason the plugs should stay in. Solvent evaporation, maybe?

Just a thought.

Nothing is going to help the start up noise pn a 5.3. It's piston slap. Mine has done it since I got it.
If it makes you feel any better I've got well over 250k on my 5.3 and no sign of giving up yet.

 

[Grebbler]

Yeah. I am not really worried. But it did get noticeably louder and longer lately and I was thinking carbon buildup, which should sound the same, might be hiding in the noise. We get some awful gas around here and once in awhile a quart of oil disappears from the motor.

I checked the PCV and it's clear but maybe I should find one of the new style orifice types and see if that helps.

 

[Clevy]

Try regane or techron in your fuel if you suspect carbon build up. They work well.

I had the valve tick on startup on my 04, 5.3 tahoe. I used Kreen about a year ago I guess and not only did the tick disappear but it has not come back to this day!! I have only kreened once since then. I say try it and let us know what happens. It DID work for my Tahoe.

I did a piston soak on a 2003 Nissan Altima 2.5L. I reinstalled the plugs as the instructions say.

I assume that you installed the plugs to seals the cylinders and make pressure during compression, while the engine cracks. This forces Kreen down into the rings, etc.

Just dont get carried away. Hydrolock is a possibilty. But I think it would be fine with just a few table spoons.
I would personally put a quarter quart in each cylinder and let it sit over night and then pull the plugs back out and crank it over.

UPDATE: performed a kreen purge approx 3 wks ago and hoped to see some major improvements in the oil consumption arena. Well, still consuming oil, still at about a 1qt every wk depending on driving styles aggressive/grandma style. For me the kreen has not done what I had hoped and I unfortunately don't have the dispensable income to order more kreen on the schedule necessary. As mentioned in some of my other posts I have a friend that can get me Valvoline NXG on a pretty regular basis. I guess I will only be changing the oil filter on this car as I am replacing a quart a week. Good luck to other Kreen trials.

Unless this is a big block with a 4 inch bore an entire cup (8 oz.) is too much! Just a few ounces should be plenty.

Sorry to hear those poor results, but as I've said many times before it's the nature of this type of product to get used in some hopeless causes.

Kreen just got to you a little late. Good luck!

I don't understand why folks put a flush type additive into an engine with a high oil consumption, at best it won't help and at worst any kind of flush, including idle only ones can cause an oil leak or high oil consumption if the seals and gaskets are not in good shape and are being helped to function by a layer of varnish.
Once you have got rid of the worst of the sludge then just change to a major brand HM oil and keep the next few OCI's short if it turns black quickly in particular.

You don't understand why. Well let me explain it to to.
Sometimes consumption on a high mile engine is due to the rings getting coked up. No oil on the planet will dissolve this ring coking once its there so a product like kreen does remove the coke on the rings thus the cylinders seal up again and consumption is cured.
Over 1200 posts and you seem to know it all yet this you don't understand.
You understand fine. This is your way of taking shots at posters using oil additives.
The whole forum is aware of your stance on additives. Give it a few weeks so we can get some new members who don't know before spouting again would ya. No one listens to you anyways.

All the auto engineers I know think that if you have carbon deposits in a cylinder then the best idea is just going for a good blast down the autobahn. The Brits can't go fast enough to do the job quickly, so they prefer an Italian tune up (Driving in too low a gear) but they can be risky if done with an auto box due to possible high box oil temps.
Stuck rings are not an issue with modern engines and there are quite a number of more likely reasons for high oil consumption like valve guide oil seals or just worn rings.
There are some fuel system additives that are sprayed directly into the intake or added to the fuel feed line that can help clean upper cylinder carbon deposits and using one of those is a much better idea than contaminating the engine oil with a cocktail of solvents. Some of the fuel additives have full engine manufacturers approvals.

 

[SteveSRT8]

If you haven't seen any coked up, stuck rings in a modern engine then you simply don't see many high mileage examples.

We have a machine shop in our family and coked up rings are a virtual certainty in a high mileage motor with typical driving patterns and poor maintenance. I doubt they would be much of an issue if everyone got out for a 100 mph blast regularly!

I have dramatically reduced both start up noises and oil consumption in high mileage fleet trucks right here in my own driveway with kreen. Sometimes additives can help. period.

Sorry man, I'm just not drinking your kool aid.
