Seafoam Discussion

[delicat]

I asked because I have 3 one gallon bottles of the stuff

Easy solution for you, just sell me a few of those... ;)

Hey Mr. D, do you remember this http://www.delica.ca/forum/diesel-syste ... ight=purge?

The easiest way is to just take one can when you do a fuel filter change and fill the new filter with the product. However, a certain percentage of it will never make it to the injector nozzels and upper cylinder as it gets returned to the tank.

Would a looped return solve this?

The line directly below the one you quoted

Seafoam can be used for the crank oil flush and an upper cylinder/injection system flush. They recommend for the crank oil that you put it in and do about 100 kms at 100 kms/hr. Then, drop the crank oil immediately. The upper cylinder/fuel injection flush can be done in two ways.

The best is to remove your intake and return lines and run them into an enclosed glass jar. Dump in two cans and run until the jar is nearly empty. This is how I do mine and it makes a huge difference.

Dumping a can in the tank only a bit makes it to the injectors.

A brand new fuel filter filled fresh with seafoam is a good way.

The seafoam jar with intake/outlet injection pump lines and cycling it through is very thorough. It's the equivalent of a supersonic clean at a service shop however it is at your own risk of course.

If I dumped seafoam in when I change my fuel filter having the looped return on would loop it back into the IP vs. sending it to the fuel tank, it would be diluted with diesel but wouldn't be wasted.

screw that, i have 75 litres of seafoam and will just filler up! hahaha!

anyway, just waitin for my filters to arrive then i'll dump a can in the crankcase before changin the oil and then into the filter next time it needs replacing...

as always, awesome tips here folks!

Seafoamed 'er. Just dumped a can into the tank when it was 1/3 full (to get max concentration) and ran it in one trip until it read empty.

Before: ran fine, bit of a rough idle and smoky sometimes on startup.
After: rough idle gone, no more smoke.

tune-up in can indeed!

or you could pull a kramer and wait till the E light goes one which equates to 15L left in the tank (or just under 150K of driving), then drop a can in...more concentrate, heck, add 2 bottles. glad to hear that even at 1/3 tank left with a bottle made a difference (but caution regarding crap at the bottom of the tank). guess each rig is unique in what gunk/crap is stuck in different places..

The tank on an L400 is 75 litres and there is a 12mm bolt at the rear/middle of the tank underneath for draining.

Park on a slight incline and undo the bolt with a catch can/pail/drum to catch the diesel.

I just did a fuel filter change and filled it with seafoam. In the 3 years I've owned my 93 L300 I don't think I've been over 24mpg (US) even on all highway tanks of fuel, but after the seafoam I got 27mpg (US). Same driving conditions as usual. Split between city and highway 60/40.

good to know JF! curious to see what's down thar.

I bought some Seafoam because so many people have raved about it here-- and also because it was on sale at Lordco. I recently had injectors cleaned up & re-done at CVI so they don't need anything right now. My question is; when added to fuel will Seafoam do other good things for the engine or are gummed up FI nozzles the main target and main thing Seafoam helps with? In other words, should I bother using it now or hang on to it for later?
Cheers!

personally, if injectors already done up, I would use it for the "intake" thing and clean the buildup out of your intake side of things and dump what's left in the tank. Hopefully you have already added an oil catcher, or builduip will be back soon.

I've moved this thread from L400 technical to General Discussion as I find it useful for L300 owners as well as L400's.

PS. Do you have any idea how long the sale at Lordco is on for and if it's at all locations?

and how does the price compare to crappy tire? and for the standard can or the intake adapter thing version
