I have 91 Camry SV21, 4 cylinder 3S-FE engine with 130,000 miles (211,000 km).. I took off the valve cover today and this how dirty it looked under..

Now I don't know where to start from... Auto-Rx?! Are there any other good products on the market for this?

I live in Melbourne, Australia and not all this products get sold here so I'll have to see the availabilities of buying them from US and get it shipped! But just enlighten me with your experience where I should be heading at the moment, and I'll figure out a way to get whatever it is.. shipped down here..

cheers

Pennzoil HM 10w40 is what I put in my dads Saturn that had the same amount of sludge, 1500 miles now and from what i see through the fill hole, its cleaning
 
any of the pennzoil products clean well... if you can order some marvel mystery oil from amazon that would be a good match with penzoil.

Is Rottella or shell helix available in AU? they would do a good job as well.
 
I'd try Shell Helix Ultra 5W-40. It claims "cleansing technology" similar to Pennzoil Ultra sold in NA. "Up to five times more effective at removing sludge from a dirty engine than mineral oil":

agreed: use some MMO and penzoil products to help clean it up, its not good (your pics) but its not awfull either.. MMO does slow cleaning. Use the recomended amound over several oil changes and it should start cleaning things up. 2 pennies
 
I cleaned a few worse than that. Kreen from Kano Labs was the best additive I have used. Commercial product, can only be bought over the internet. Good at emulsifying the hard stuff, removing varnish. Read the thread full of testimonials https://bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=2633164&page=1

Synthetic oils are the way to go. They are great cleaners on their own, and serve as a solid base when using cleaning additives. Mobil 1 High Mileage full synthetic or Pennzoil Ultra have the highest concentration of cleaners. Rotella T6 5w40 HDEO is another option. I use the Mobil 1 High Mileage full synthetic because its not uncommon for a leak to pop up during the cleaning process. Sludge may be filling a gasket leak.
 
While the Valve cover is off, why not use some mineral spirits and clean it up manually... then put some good fresh oil it... and change it a bit more frequently. I would avoid diluting your oil with solvents.

I have some outstanding looking valve trains achieves with Mag1 on 1/3rd of 10K mile OCI's.
 
Heavy varnish/some sludge. You haven't seen sludge monsters, and they still drive fine. Like Camrys with V6 engines.
You car will go another 130k miles...
Just use reasonable ocis/maybe longer oil filters and some kreen with any brand oil you like/oil on sale(like free G-oil).
UOA is your friend.My previous Camry v6 was badly sludged(prev owner). Kreen in oil/gas/piston soak improved things dramatically. It used to drink oil like alcoholic drinks beer before kreen.But it would still kill any oil in 5-6k miles per UOA.
P.S. I just got bored, and traded it in with 158k miles on odo, and much cleaner engine than it used to have.

What type of oil have you been feeding it (and what OCI) mysterious?

Shell Helix HX7 (10W40) is readily available here in Oz (only $33/5L at supercheap Auto). You could try giving it a nice gradual clean with a few short oil change intervals.
 
my camry looked just like that and it had castrol. not by me but from the guy i had bought it from. i would run 10w40 pennz. i say 10w40 because if its a typical 3sfe it probably drinks oil like a drunken Irishman .
 
Another vote here for either an HDEO or good syn like M1HM. Stay away from additives - as others have said, you really don't have it all that bad.
 
For all the posters that are recommending Pennzoil, the closest you will find in Australia is Shell Helix HX7 as far as Shell's advertising is concerned. That is what I would use.
 
Hey fellow Australian BITOGer!

I had great sucess removing sludge/ carbon like that with diesel and a parts washing brush. Just add some elbow grease! you'l find it will remove just about everything.

After I cleaned, I poured a cheap oil/ diesel mix over the head to flush the [censored] out, followed by a cheap oil fill and run for 20 mins then new filter and good oil.

I used a 15w40 HDDEO for a short OCI then switched to a syn. Try Delo 400 or my fave, Anglomoil Roadmaster 300 (3500ppm Calcium)

Didnt realize he was in Australia,
Sorry Mate, M1 HM or Shell Helix will do as well
 
Not great, but as far as "sludge" goes I've seen much worse. You've gotten some cleaning oil advice, M1HM, HDEO etc., I won't add to that.

I would shorten the oci's for a while, and definitely change the PCV valve. Likely looks pretty nasty too and needs to be changed.
 
I'd lean toward shortened intervals, using relatively inexpensive oil. HDEO are cheap and clean well. Change every few thousand miles, or when the oil gets good and black.

Unfortunately we don't have penzoil or marvel mystery oil in Australia, but I can buy them from Amazon and get them shipped over here from the US and I'll have to pay an extra non-refundable $50 "Dangerous goods fees" coz they're flammable goods..

But we do have shell though, last time I used shell on this car it felt a bit slower and sluggish and not as free revving as running it on Mobil 1 feels. This was 3 years ago so I'll give it another try when I do my oil change next week.

I don't think a flush product would solve the problem, but why shouldn't I use it anyway to help a bit?

Yeah most likely I'll go with Mobil 1 high mileage, If I am correct, I think it's dubbed under a different name in Australia something in the lines of "older engines formula" or something like that.. I just hope it's not too heavy on the engine, those Toyota engines love light oils, if I put anything heavier than 10W-40 (e.g. Castrol GTX 20W-50) I feel the engine isn't as free revving and the car is a bit slower.

I wouldn't mind doing that except that I will only clean the top of the engine, I won't be able to reach down everywhere

it' too tight and squishy.. I'd also be scared if some pieces of the scrapped off sludge fell deeper inside the engine and clogged an oil passage or something. What kind of spirits would take this sludge off anyway? it seems so thick and dry, I could barely scrap tiny bit off the valve cover with a screw driver.

I use Mobil 1 Gold 0W-40, my dad buys it for his BMWs, Merc and Jags.. So we always have excess in the garage, and I get it for free

This one:

It's doesn't seem to be a bad oil.. engine feels very smooth on it and the car pulls a lot faster and feels very free to rev than running it on other oils. I haven't experienced any oil leaks/burning so far.

My OCI(s) are very bad, last year I had uni exams and was so busy with work.. And I didn't service my car for 30,000km (18,600 miles), When the poor car's lucky day came and I did a full major service I discovered that I had a puncture in my air filter that was leaking all kind of dust and contaminants inside the engine and the oil was pitch black!

So it's my fault.. This car has been in the family for 20 years, my dad bought it brand new in 1992 he used for a bit than gave it to my mum then my older brother then my other older brother then I got in 2008. It's still registered under my dad's name all these years, it used to get serviced at the Toyota dealer till 2008, but as soon as I got it I stopped taking it there, waste of money for a car that old to keep on paying $300-$400 per service. When the time comes to sell it I'll put in the advertisement "one owner for 20 years" lol no one would be believe it though, coz any Camry with that age will have at least 4-6 previous owners. I am not selling it soon though, it's a decent car for this stage of my life.

Yeah, I've heard a lot of good stuff about Kreen but we don't have in Australia and Kano labs don't ship overseas coz it's flammable.. *sigh*

I can't find the PCV valve on these 3S-FE engines. I've asked on Toyotanation.com forums and got one reply saying those engines don't have a PCV valve, they just have a hose to take away the extra oil when the crankcase is in high pressure, but I am not entirely sure he's correct.

OK, thanks for the help everyone.. I'll get a HEDO and shorten my OCI and see how things will go, if no big improvements, then I'll add MMO to the mix..

Oh and one last thing, can anyone define a short OCI? is 5000km (about 3000 miles) too short? too long? average? All what I do at the moment is city driving.. so how long should I run the oil for to get good clean results?

I'll be following up with pics when it gets clean..

cheers.
