Sludge

[batman]

I pulled the valve cove off of the 62 today and there was oil caked everywhere. I cleaned the valve cover and then I used the shop vac to suck up the caked oil on top of the head. There was so much, and I am sure I didn't get it all. But my question is what can I use or do to remove all of the sludge from under the valve cover and from top of the head? Is there a cleaner, or can I remove the spark plugs and drain oil and the pressure wash it?

TIA

Put the lid back on and pretend you have a clean engine.


It really does not harm much other than being funky

i think seafoam in the crankcase might help but not 100% sure

Leave it alone - it's holding your engine together!

BUT IT WAS THICK..... I mean chunks were comming out 1''x1'' size chunks.. Seems like that would have an affect on the oil flow some how...

There is more of a possibility that you will dislodge some of the chunks and they will get trapped in the motor causing issues than if you leave them alone..

With chinks like that, MACE is right...

In that case, I would go with the Seafoam in the crankcase. I would pour it in before taking the truck to get an oil change and drive it for a half hour or so, then do the change. I haven't done it myself, but that seems to be the most recommended method of doing it.

To avoid more buildup in the future, I would switch to a full synthetic oil and always use a high quality filter (K&N or stock Toyota, though Toyota doesn't make the large filters anymore, so I use K&N. The HP3001 is the right model for our engines). I've been running synthetic for years and my engine gets cleaner every time I change it.

Hey cabron, you said "chinks". For shame sir, for shame

With a buildup that thick you are looking at a rebuild..
That motor has been very abused.

Good oil will not make much of a difference.

I'm usually so good about checking my spelling on things. Just think, changing one letter accidentally, put down an entire race. Deep.....

I had to point it out. It was just too funny of a typo to let go

I have 209K miles on it and it runs strong abused or not. I does leak oil but very very little, and I think that is the oil pan gasket that is leaking.
I am going to invest a little money into it when I get a chance, I have been thinking about a 350 swap and then rebuild the 3fe and find myself a non running 62 to drop it in.

I never said it would not work for a long time. I said it was abused (lack of oil changes) and to solve the gunk problem you would have to rebuild it.
