Very true, I can't see any sludge just a little light varnish that is normal for older engines. That varnish will be helping the oil seals and gaskets to function, it should be left in peace.

If you own a late model Toyota your both wrong. Any deposits matter including the precursor to sludge, varnish. Toyotas have narrow oil passages in 2 key areas. One is the vvt-i system, the other piston oil return holes. If enough varnish gets into the tiny passages of the vvt-i, a host of operational issues will be experienced as the controller hangs or gets stuck in the wrong phase. If enough varnish gets into the piston oil return holes it can flash and harden into carbonized mass. Thats a bad thing. Will burn oil like a Saturn because the oil scrapings cant return to the sump. Usually a teardown is required to clear the holes with a drill. Primary reason why so many Toyotas burn oil is clogged piston oil returns, nothing else is usually wrong. Clogged with carbon deposits whether sludge or varnish. Can't generalize like that. It does matter to some engines.
 
I can only comment on the pictures as you can't see the oil passage ways, if the engine is sensitive then it should use a high detergent full synthetic with short OCI's, then there will be no need to remove the valve cover. Oddly enough I would be more concerned with seeing the sump and oil pump screen in particular.

WTH??????? Varnish doesn't "help" anything function. If a gasket leaks, it is defective, and needs to be replaced. "Sealed by varnish" is not a valid maintenance strategy.

^-- This.

Of course, we've all told him this a hundred times.

Telling skunkship anything is actually similar to beating head against a brick wall.
 
Instead of answering questions directly Skyship likes to go on rants and impress everybody with his 'profound' knowledge. He also often talks in circles. It kind of makes you wonder about him.

Not really. If Trav, demarpant, and I were beating our heads against a brick wall, we'd give in long before the wall. I don't know about those two (who were called out earlier in another thread, thus why I mention them here), but as long as attempts at getting him to have a logical discussion result in hilarity, I intend to keep trying.

$22 shipped for a quart?

After all this cleaning, I don't have any leaking seals. The engine is bone dry all over. The original, OEM oil pan gasket is still dry after 15 years.

Just wait, it's about to start leaking any day now. Well... whenever Skyship finds where you park it, that is.

Also... if electro doesn't take it all, I'll jump on a quart at that price if you'll ship to CA.

If it does Kreen will work, if not it probably will not because its in the pores of the metal.

I have had a few engines where it didn't remove the varnish and i had to do it manually, others it did.


Have you tried what Trav mentioned with carb cleaner? If not it would be easy enough to do next time you pop the valve cover. It looks like that metal is stained and you've done about all the cleaning you can with an additive. Beyond this manual cleaning, which would be totally unnecessary, would be the only other option for this engine. Another dose might show some slight improvement, but I think I'd stop here if I were you.


No, I haven't tried that yet. I'm pretty sure it will remove it easily. I touched another area of build up with my nail and it seemed to come off with ease, I don't know why these supposedly good cleaners can't remove this stuff. I mean, there's improvement but it sure is taking forever.

By the time I get this block clean, the car will have 300,000 miles on it and I'll be ready to take it to the junk yard. Seems like someone else will benefit from a very clean 1MZ-FE. Haha
 
I don't know, I'm only like 500 miles into the new fill. I'm thinking of adding 16oz of Kreen every 500 miles instead of ever 1,000 to speed things up. Many say that it evaporates within a few hundred miles anyways.

What do you guys think?

Can't hurt as long as you're not overfilling

Sounds like a good plan. Will this vehicle see short trip driving, I think someone posted here that short trip driving was better when using Kreen.

She does lots of short trips around town but I can take off on a 500-1,000 mile road trip at any time (business related).

So far, with the fresh fill of oil + 16oz of Kreen, the engine has saw nothing but short trips during the first 500 miles. I will add another 16oz in the morning.
 
When I ran it last time I added it when the oil level dropped back to full, which was about 500 miles. It seemed to work better that way.
If its all evaporated your not over doing it.
