Qslim's sludge pics are up!

These photos are downright scarey! Much worse than I would imagine. Perhaps you've posted all the particulars before, but could you summarize them: Type of car/motor, precise mileage, age of motor, time oil was in motor, type of oil, type of driving, climate ... anything that might be relevant. If you've covered this before, I apologize, but I haven't seen the details. What a nightmare! These photos should be shown to car-owners who don't think regular oil changes are important. Thanks for the photos. B

Very interesting boys, thanks...

I've done plenty of those in the last few years. Being a 2001, its mainly that 8700 miles have taken place over three+ years that caused the oil evaporization/sludging.

It always happens on unmaintained cars, regardless of make.

I'm impressed with the 5S-FEs ability to keep going and going when sludged. Unfortunately for the 1MZ-FE though, it has cylinder sleeve liners that will develop a "double ridge" at the top of ring travel when the sludge freezes up the compression rings. Last I checked our machine shop said they couldn't bore them and/or get oversized pistons. Though in both cases the bottom end and cams/journals hold up great in both "problematic" engines.

Of course, you're talking to a person who, every time he DID buy a NEW Toyota, changed the oil at 1500 miles, and then again at 3000 miles...

Thanks for hosting those, great pictures, however horrible to look at. Crazy how somebody would not change the oil, but build up like that on only 8,700 miles? That does not seem right.

Something else interesting that shows up in the pics is the rusted exhaust bolts (nuts/studs?). What's up with that?

...

Yeah, I wasn't paying attention to the age of the car. For me, 8700 is about 3 months!!!

On average about 6 miles per day over 4 years. Very short trips means you should get your oil changed more often than what the Mfg recommends as best case, 7500 ect. The owners manual specifies this very clearly as short trips, stop and go driving ect oil should be changed every 3000 miles.

Hi all,

I feel these pictures are not true for a 2001 / 8,700 engine, I have a 2000 and it looks much better, cleaner . Look at other pieces , we can see the rust and surface of these pieces, they can not be that old , especially this one :
