SOURCE: How to use seafoam on Z32 (1990. nonturbo)?

there are multiple ways to use seafoam on a z32:
gas tank- just add into gas tank to clean injectors, fuel lines, remove deposits from tank itself and clean the valves.
throttle bodies- while leaving the maf sensor on the intake plugged in remove the throttle body hoses one at a time and SLOWLY pour in a little bit of seafoam as a friend revs to about 2k rpms. hold onto the can because there will be suction that can pull the can into the intake. (essentially this is a vacuum approach.
oil- add whole can to oil through the oil cap. run for about 50 miles and change oil. the longer you leave it in the more it will clean things.

depending on your reasoning for wanting to seafoam it the method that would work best varies.
for ticking lifters- through the oil as the ticking sound is a blocked check valve in one of the lifters causing it to slap against the camshaft.
(wynns hydraulic valve lifter treatment from the uk works wonders too)

for cleaning injectors- through gas

just for an engine flush id put half in oil and half in gas run for 50 or so miles and then do an oil change. the gas will take care of itself.

hope this helps...

I need to find the air intake hose on my buick regal 1996 to add seafoam, where is it? Oh yea its a 3.8 v6


There is an Air box under the hood near the front of the engine compartment right behind the headlight housing. But I wouldn't use that if you want to seafoam the engine. You would have to bypass the mass airflow sensor in order not to damage it. Your best bet is to disconnect the brake booster vacuum hose line and administer the seafoam through that.

ENGINE IDLES ROUGH, BUT RUNS FINE WHILE DRIVING. My car is a 1995 Buick Regal Gran Sport with the 3800 series motor with 212000 miles. The rough idle tarted after driving through some muddy and wet roads


go the cheapest route. replace fuel filter and add SEAFOAM to tank of premiun fuel. replace filter before 500 miles. then add SEAFOAM to gas every 3000 miles to keep lines.engine,fuel pump, and emissions systems clean, ETHANOL problem number 3000

Do a three-part Seafoam treatment to see if it helps. You can buy Seafoam at a parts store or in the auto section of walmart. Get two cans.

Pour one entire can into the gas tank. This will clean the tank, lines, filter, injector pintles, etc.

With the other can, pour half into the oil, drive 60 miles or so, and change the oil and filter. This will remove oil sludge, varnishes, and deposits.

Remove the vacuum line from the vacuum pump on the back of the engine (or any other vacuum line into the engine), start the car, and with someone holding about 2000 RPM on the engine, allow the engine to **** up the last half can of Seafoam. It will stumble and run rough. Let it run for about 10 seconds after the Seafoam is sucked up. Then shut it down for 10-15 minutes so the Seafoam can go to work breaking down the carbon deposits in the engine's vacuum system. Then restart the car, let it idle for a couple minutes, then rev it several times to 4-5000 RPM. You should be seeing a LOT of smoke out the back of the car. Let it idle again and rev it up every couple minutes. Do this until you're not seeing much or any smoke. A little bit the next time you drive is fine - it'll finish burning off.

I've done this on many cars (most of them Audis) and it's made nice differences in smoothness, economy, and a little power even.

Also, make sure your other fluids are topped off, your air filter is clear and clean, the tires are inflated properly, and that you have no stored codes in the computer (stop at AutoZone and ask them to scan the ECU for codes - some latent codes won't trip a check-engine light but can alter the car's performance).

Rev counter


The idle speed controller is having trouble regulating the idle RPM to the speed the computer is asking. Go to the parts store and get some Seafoam (about $8/can). Pop a vacuum line off the intake manifold, while the engine is running, and feel for suction. When you find it (it should be sucking air into the manifold), put a tube into the can of Seafoam, and allow the engine to **** up about half the can. You may need someone in the car to hold the RPM around 2000 (the engine will bog and may want to stall out while it's taking in the Seafoam). When half the can has been pulled in, pull out the tube, wait for the engine to stabilize a bit, and put the vacuum line back on. Let the car idle for about 15 minutes so it can burn away the carbon deposits that the Seafoam is freeing up. Rev it up to about 4000 RPM every 10 seconds or so for a minute, and then periodically while the car is idling. You won't believe the smoke that comes out the back of the car, but that's what is supposed to happen - that's the Seafoam burning away the carbon that has gotten all over the inside of the engine, and is likely clogging up vacuum lines, the idle controller, EGR system, etc. It's great stuff.

Save the other half of the can to treat the car again in a week or so, or dump it into the oil, drive 30 miles, and change the oil and filter (it can break down oil sludge and deposits as well). Don't drive more than 30 or so miles though because the oil will be thined out and too much more mileage than that may compromise the oil's ability to properly lube and protect the engine.

You can get a second can of the Seafoam and pour it directly into the gas tank as well, and it'll de-resin the tank and lines, clean the injectors, and clean out the fuel pressure regulator as well. The stuff is as close to magic as you're gonna get and it works great. I've done about 20 cars with it now, and not one person has called back saying that they're car isn't much more peppy, efficient, and smooth.

I would try to replace the fuel filter then run the cleaner through with the follow up use of seafoam, seafoam is an engine cleaner that you can use in different ways, through the fuel, through a major vacuum line or in the oil. If you go to your local auto parts store and ask for a can of seafoam and describe your problem to them they should show you how to best use it.

Egr trouble code 35 keeps turning light on


It could simply be that the EGR valve is clogged. You could try doing a Seafoam treatment on the vacuum system to see if that can free up the EGR (you can get the Seafoam at AutoZone or any other parts store, and it's cheap). You'd need to find a vacuum line you can easily remove, and feel suction into the engine from. Pour some Seafoam into a bowl (maybe 1/3 of the bottle), and use a small piece of vinyl hose to get it into the engine. Put the hose into the vacuum nipple, seal around it with tape, and dip the other end into the bowl. Rev the engine as needed to allow the engine to **** up the fluid. You may need to rev it up during the first couple minutes following the ingestion of the Seafoam - the car will blow black smoke out of the tailpipes and may stumble and run rough. This will let up as the engine burns off the excess carbon inside, and afterward your car should run quite a bit better. Put the vacuum line back on and you're good to go.
