Ok dumb question of the day

I'm interested in cleaning my engine parts in the dishwasher. What parts should I not put in there? Are valve guides and seats ok? What about the front seal (neoprene seal)... ok let me have it... I'm ready for all the criticism

 

Anything your wife does not know about will fly. I baked headers in the oven and have washed many parts in the DW

 

No more wife to worry about here...

 

So the hot water won't damage the valve seals or front seal?

 

No, the water can't get any hotter than the engine will already be running. Since it isn't under pressure, the water can't be above 212°F where as the block, under pressure can have water to 220° without boiling. Also, the heads will heat soak to well over 200° from combustion. Plastic containers don't melt in my dishwasher and that certainly not true if you put them under the hood.

My question is what are you going to run through it? Are you going to use dishwashing detergent or some special mixture? Curious minds want to know.

 

I hope you will be replacing all the seals.

 

I don’t see any cleaning advantage using the dishwasher.
You’ll probably ruin it with any carbon and goo that falls off and contaminate the inside, I don’t think I’d use it for washing dishes anymore.

 

Use Cascade triple action, it prevents water spots and no pre- rinse needed!

 

Lololol, yep nothing more embarrassing at a dinner party than water spots on your crank

 

Some metals do not like the chemicals in modern dish washer deteregent/pods. Aluminium comes to mind. Won't hurt it but it will discolor. I'd use the cheap soap only stuff.
Using purple power, some brushes, some heat, and power washer will get safer and maybe better results.

I would only put in plastics that are under the hood, maybe not. I would not do any interior parts.

 

Degreaser and a power washer does the trick.

 

I'm most concerned about the valve guides and seats since they have some plastic

 

Ok. I'm thinking iys a no go, my motor failed due to some dirt getting in it, I just want to make sure I get all possible said dirt out from hard to reach places such as in between springs, small bolt holes etc...

 

LOL that reminds me of when I put my timing chain cover from a 340 through the DW.
Last thing I washed that way was some turbine wheel covers
