Toyota Top Engine Cleaner

[Spanky Pete]

I picked up a pack of engine cleaning products from the Toyota dealer today. It includes throttle body/valve cleaner, EFI fuel additive, and a "Top Engine Cleaner".

The instructions on the bottle of top engine cleaner describe a tool that is attached to the bottle. I am trying to figure what the tool looks like, then I can determine if I need it or can fab something up.

Sounds like the contents of the cleaner end up getting sucked into a "central vacuum port".

Searched on this, but didn't find anything.

The Top Engine cleaner sounds like SeaFoam...??

Motor Treatment - Sea Foam

A few threads out there on how to "ingest" into your motor...search is your friend, and follow the instructions.

Cheers,

Thanks Steve. Yeah, I did a little more searching on the web and it does sound like sea foam is the same kind of product. Looks like GM sells a similar product under their badge.

So for administering this toyota brand sea foam, sounds like I just pour it into a vacuum hose on the intake, probably with the aid of a funnel. I don't see the need for the Toyota "Top Engine Cleaning Tool".

I will look closer at that sea foam link for tips and details.

Just pull one of your vac lines off (be sure it is a vac line that runs to your central vac source), pour a LITTLE into the cap, and suck it up with the vac line.

Do not use too much of this stuff as it will smoke like crazy which is to be expected, but can also damage O2 sensors. I put too much in my Taco and had to replace both the up and down stream O2's.

Hope this helps

I used something like that just recently, it came with a section of clear 3/8 hose and a universal type plastic adaptor. I shoved it into the PCV intake port on the throttle body and let it get sucked in a bit at a time while working the throttle with my other hand to keep the engine from stalling. HTH.

Marvell Mystery Oil used to sell a vacuum operated top end oiler that plugged into a line just below the carburetor,,not sure how it would work on fuel inj.

What would be best to know is what vacuum line would be best to suck this stuff from. What will clean the majority of the vacuum system?

some of those products are designed to use a "tool" that screws down on top of the product and the other end connects to the fuel rail. It resembles the hose and connections used on a fuel pressure tester.

I ended up using the product by just pouring it down the brake booster vacuum hose. Just a 1/4 of the bottle at a time, rev the engine until exhaust clears and then repeat. It did trip the engine light, probably the O2 sensors, but disconnecting and reconnecting the battery got rid of the check engine light. No special tool necessary.
