Where do I stick the Sea Foam?

[Gig'em Ags]

Okay, I know there are plenty of people out there that would love to tell me where I can stick my Sea Foam, so go ahead, I've got thick skin.
My real question is that once I've put Sea Foam in my gas tank and in my oil to clean all that out, where else do I put it? The can says something about putting it in the intake and although I know where the intake is, I'm not sure how to put it in there or exactly where in the intake to put it.
I appreciate any advice on this. Thanks.

Gas and oil.

Through a vacuum hose. I have done seafoam many times in my hondas/acuras. But I am newer to the disco so I am not sure where the vacuum hose is located off the top of my head. IMO through the vacuum seems to be the most effective way vs gas/oil. Do it while the engine is running with the vacuum disconnected the idle will surge and you SLOWLY pour the seafoam into the vaccum hose using a funnel. When pouring in the car will be on the verge of stalling but go slow enough and it will keep running. Once it is all in, reconnect the vacuum hose and shut it down. Let it sit for 15 min or so. Start it up and the exhaust will smoke like mad. I then took it on a 10-15 min drive. If putting in the oil, I usually waited until I was just about to do an oil change just because it will get pretty dirty and I don't want that cycling through the engine for 3k miles.

Wal-Mart sells it 5.99 a can, next to all the fuel additives.

there are a couple vac lines in the front of the intake. one has a little red washer, if you push the red washer in while pulling the line out, it pops out.

As I understand everything, I need to:
1. Warm the engine up.
2. While the engine is running, pull the vac line with the little red washer from the front of the intake.
3. Use a funnel and slowly pour about 1/2 can of sea foam into the tube, being careful to not pour so fast that the engine stalls.
4. Replace the vac line.
5. Shut off the engine and leave for 5 - 10 min.
6. Start engine and watch the smoke roll out the back (and the cracked manifold).
7. Once the smoke has cleared, take it for a ride and enjoy the improved performance.

Doesn't sound too hard. Thanks.

pull that vac line, and quickly plug the hole with your finger so you dont stall. have a spare piece of tubing that will fit in the hole ready, take your finger off and stick the hose in. now cover the other end of your hose with your finger so you don't stall...again.

now have 1/2 or 1/3 of can of seafoam ready. slowly suck the fluid in through the hose, youll feel the engine close to stall, if it gets close pull the hose out of fluid, keep going until you are done.

take hose out of hole while engine is still running, push your original hose back in and shut vehicle off. give it 15 mins and fire it up, you may or may not get smoking, drive it like you stole it.

The smoke screen to me was the best part of the whole procedure

my d1 has no such red washer.....

also, my d1 does not stall with the vacuum hose removed. hmmmm........?

they also see seafoam deep creep......seafoam in a spray can.

 

[///M3///M5]

Just did it yesterday with my oil change...

I poured 1/2 in my oil first.

Let it idle.

Pull the VAC line for the charcoal canister where it enters the intake plenum (has a red ring around it).

Stuff a fuel hose in the open port and suck up the rest of the Seafoam via the hose with the engine slightly reved so it will not stall.

Replace vac hose.

Let idle for 15 mins.

Change oil and filter.

Be on your marry way...

i dont think d1's have the red washer

I also think the hose leading to the red washer is a vac line for the brake servo

either way, just pull a vac line to suck the stuff into the plenum

Thanks very much. I pulled that hose and turned it upward and just poured the Sea Foam in while it was idling. It almost stalled a few times, but as soon as I eased up on the amount I was pouring in, it sped back up.
Once I had poured in a little less than half a can, I shut off the engine, replaced the hose and let it sit for 15 minutes. (And drank a beer.)
Then, I cranked her up and the smoking began. (I think I'll be the talk of the neighborhood for a week or so now.) I let it run for half an hour and it was still smoking, but not as badly, so I shut if off and will run it again Monday on the way to work.
I hope to have a smoother running engine now. Thanks for everyone's help.

Every spring, I've used Seafoam to de-carb my boat motor...would like to do the same as above for my D2. Can anyone help me figure the vacuum line for the D2? In advance, thanks.
