What I found in an engine

[Zuffen]

The following photos show a little of what I discovered inside a cam cover on a blown engine.

The engine was originally in Guts's Hi Lux but it blew ahead gasket.

Looking at the amount of crud in the cam cover I don't think it had had any maintenance for many years.

For reference the socket is 10mm on a 3/8 dive.

Got sludge?

:eek1: OMFG Glad mine didn't look like that.

I guess it's a testament to Toyota, to have still been going with that kind of neglect.

That is ugly.... I change my mobile 1 oil every 2k miles. Speaking of neglect....WOW

 

[jibbby]

Someone definetely missed a few scheduled oil changes...Did you know that running a quart of transmission fluid in with the engine oil for a breif time acts as an engine detergent to help clean up the engine internals, free up sticky valves, help with noisy lifters, etc....That is an old mechanics trick that actually works...... However, I don't know even if that little trick would clean up that big mess....

A lexus Tech once also told me about the tranny fluid but he said leave it to the pros haha. I have never seen sluge like that, but the motor kept on chuggin!!! Any score marks on the cams, crank or anything?

I haven't looked any further than the one cam box.

I use the engine for mocking up parts and only opened it up to salvage a cam for another member.

The cam looks fine but the heel of each lobe is quite discoloured by the sludge.

looks like something you see in the lifter valley of an old small block w/ 400000kms and can't remember its last oil changenever seen anything like that in a overhead cam engine...............I'm impressed

I never saw any dirty engine internal like that. It could be the worst that I've seen. A long time ago, I have an uncle who didn't change the engine oil in a Mazda MPV for around 15,000 miles. He sold it back to my dad and it ran fine with regular oil change afterwards. So I conclude this engine had not seen any oil change for a very....very...long time. I don't know whatever usable parts are left.

I think my brother's old Honda Accord was driven for like 5-7 years without changing oil. Dont ask me how it happened, but it did. He sold the car now, but it was ok while he had it. Oil leak from all over the gaskets.

 

[jibbby]

See what the EGR does to the engine internals..... Helps clean the invirnment but polutes the engine....(he he)

 

[Zuffen]

Jibby,

This engine doesn't run EGR as it's aa Crown engine from a halfcut.

This is a good reason to start up your halfcut before accepting it.

I suspect the engine didn't blow a head gasket when Dave (Guts) owned it but rather had blown it when in Japan and Dave was sold a dud.

Your brother's Honda didn't see any oil change for 1/2 decade. Unbelievable! And there's still some oil to leak around...:smileysex

 

[deankdx]

thats pretty impressive, makes me want to open mine?
that site is very common in Ford Falcon 6cyl motors that get oil top ups in stead of oil changes. My old ute used to go through 1 litre of oil a week i used to feed it second hand oil so with 300,000kms it would have looked similar inside.

I know Zuff...I was just kidding around as usual...The EGR if there was one would not dirty up that part of the engine anyway...

I got shafted buying a engine & box from -----(am i allowed to mention names??)
When i was checking oil pressure the gauge would go up to 50bl then fluctuate, i drained the oil & about a litre came out so i removed the sump, i had to scrap the sludge out of the sump, it was so thick i wrote in it & you could still read it weeks later, my guess it had done 10's of thousands of k's without servicing

 

[Guts]

MMMM what happens when you buy site unseen off somebody that thinks he is doing you a favour.

When I changed the sump to the rear CRS one it had some crap down there and I thought hello what have we here, with that sinken feeling in my gut, but it was NOTHING like that.
Out of interest I did 50kms of hard 4x4ing with that motor and it was still going when I removed it. It was leaking bucket loads of water out the water pump but and the radiator water was doing some funky stuff LOL.

But Rod you can rest easy knowing that the motor I got off you is going great guns.

I've seen engines that had a "loaf" of crud in the shape of the valve cover, figured it was from using a parafin(Pennzoil) based oil, and not much in the way of regular maintenance.

 

[V8superlux]

I've seen alot of filthy engines in my time but that ones great!
What makes it even more special is that the 1UZ is such a good breathing engine that normaly gets bugger all sludge. Two things come to mind, it might not have ever been serviced knowing that being a Japanise market car its life would be short lived, Have seen similar things in gearboxes caused by additives (like Slick50).

ive seen the ugly. this motor went for a few months with sluge instead of oil till a rod let go. this was a customer car at my shop, i also had someone come in with breaks so bad that they ate all the way through one rotor and the surface of another one was warn off and it looked like a water pump. both front clapers ended up needing replacment.
