Kreen Update

[Trav]

If the engine does not use hydraulic lash adjusters (i don't know what it has of the top of my head) Kreen or anything else will not help with the noise, it needs a manual valve adjustment.

You plan is fine i would add 10oz to the oil after you do the piston soak and OC and leave it at that, i wouldn't top off with Kreen if the level goes down a bit.
Save the remaining Kreen for the next OC and use a full bottle of Redline Sl-1 initially then smaller doses at regular intervals to keep it clean.

^This. I may actually do something along these lines for my app.

BTW, the Civic needs manual valve adjustments indeed.

 

[JZiggy]

Yes, I have adjusted them. I have verified that it is not a valve noise I am dealing with. I am hoping that the Kreen will clear up the rings if they are sticky, otherwise I'm just banking on superstition!

 

[Trav]

It sound like its worth a shot, the stuff does free rings if they are stuck.

 

[JZiggy]

Well I followed the steps I posted before - it smoked a bit on startup and the exhaust smells like Kreen!

(Side note, I was expecting Kreen to smell nasty like PB blaster or acetone but it's more like an industrial cleaner.. it doesn't really smell "bad" just strong!)

The cold start-up tick was quieter this morning, but I need to wait before making a judgement on it.

How does Kreen stack up against other oil additives that have been mentioned on this Forum?

 

[RnR]

Personally, I don't classify it as an "additive", which I would define as a supplement for continuous use. But used to attack an engine with nasty looking or neglected internals, I'd say it's one of the best consumer attainable products you'll ever find.

Top tier in my book.

If you're looking to clean up an engine in about 1000 miles, avoid a long drawn out hit or miss process, don't want to use a fast flush, or would prefer not to use MMO since it takes longer, GO FOR IT. Kreen would be the best of the bunch. My brother recently used it in a new to him boat with great results, we've tested it in small engines with great results, and I'm about 300 miles into it in my E-150 [no reports yet]. I'd say its well worth it for someone looking to clean an engine in short order.

+1!

^^^Yes^^^

Kreen is for people who want results, not long drawn out procedures.

Thanks SteveSRT8, if I ever come across an engine that needs serious cleaning and I need quick results, then I will purchase Kreen.

I am just not sure what you mean by LONG DRAWN OUT PROCEDURES, I guess that is another oil additive that has been mentioned on this Forum.

 

[ltslimjim]

Generally, 'quick' is cautioned against, but Kreen has been a real winner so far. I'll be getting some soon.

I am thinking that if Kreen can clean up an engine in 5000 miles or less, then it is a QUICK Cleaner.

I was speaking about ARX, which IMO is a long drawn out procedure. Never did a thing for us in many different tries.

A QUICK cleaner is a flush. Kreen can clean an engine in about 1000 miles, not exactly quick, but slow enough to be safe. And fast enough for results which won't take a year, possibly two, or more in some cases.

One of these being engine deposits on some vehicles because of a neglected PCV valve.

I see so many engines that have the PCV in obscure locations,some bolted in,screwed in,hidden under covers etc.
These more often than not get neglected simply because they cant be easily found and the darn manuals don't specify a change interval.
With tune ups sometimes being specified at 100K chance are the poor PCV doesn't get serviced either,
even then if its not stuck right in the valve cover with a hose connected to it there is a good chance it remains in there for the next round.

Many cars today have screw in valves that are difficult to find,look for the valve even on a GM 3800 GENII engine.
I go 30-50K and change them,this seems to keep things in good working order.

One last thought is using OEM valves instead of aftermarket.
There is such a difference in quality these days that using aftermarket valves can be inviting problems,IMO go OEM.


Trav, ive never been able to find one on my 06 5.3 ltr silverado, your input ? i think i asked Chevy over the phone about it and i got a responce like there were some model years that got them and others that didnt.. sounds fishy, but ive not found one..

The PCV valves, if cleaned thoroughly, can be reused over again.

I usually give the PCV valve a good spray and then a soaking in brake cleaner for a few days. Then just Dry it off and let it air dry naturally before storing it......to be used in again in a few oil changes down the road.

Rotating and cleaning these PCV valves is easy and will insure optimum performance.

 

[mongo161]

Still......there are no pictures of before and after use with Kreen?

Does anyone really use this great product?

Otis it should be on the driver's side valve cover in the back, on top. If it has been in there a while, good luck in removing--they seem to get glued to the plastic insert in the valve cover

True & good, but how much are you putting into this process with time & products when you can just get a new one for a few bucks?
