one of the claims the seafoam people make is that you can dump half a bottle into your crank case to clean out the sludge. so, unless you're driven a ton of miles with that crap in there, you should be fine as long as you do an oil and filter change. I'd do a second change after 500 miles or so.

but what made you think you needed to do a seafoam treatment in the first place ? I've only seen that stuff do more harm than good and add a wasted quick fix step to the process of finding real root cause

 

When you consider what the inside of a high miles neglected engine can look like, part of a can of Seafoam will just get a little of what is in there. There are industrial level solvents that will get it all, but they eat away all the seals as well. People have all sorts of "liquid mechanic", from kero to ATF to fancy formulas. Anything that works real fast can break down the sludge into chunks that clog up the oil intake screen. Slow over a period of time would be better.

In one of the pix you can see where the Seafoaming got a little of the intake cleaned up, but mine were so dirty that several Seafoams did not clear them off. On the D1 the PCV system puts oil fumes into the intake to burn, but some of it coats the metal and attracts dirt. In mine the hose from the driver side was bringing in oil as the PCV on the other side was blocked up.

Seafoam and other such wrenchless formulas may keep a clean engine running clean, but can't take on the severe sludge. Frequent oil changes are best thing you can do if you have a clean one.

 

It's not that I thought it "needed" the treatment. My Disco is still new to me, and it doesn't seem like it has a lot of "get up n go". Maybe that's just a characteristic of Disco 1's, I'm not real sure yet. Wanted the see if the Seafoam would change that at all. I did lots of online researching before I decided to use the Seafoam, and I conlcuded that I was willing to give it a try.

How does everyone feel about me adding the last half or so straight into a half filled fuel tank?

 

it may make the injectors a little cleaner, but its not going to make the car any faster. A dog is a dog, no matter which end you examine it from. the real magic is off road, otherwise... think about it more as getting there in style, eventually

 

That hose you poured the snake oil into is the crank case ventilation hose, so poured the Seafoam into the engine oil.
No big deal, wont hurt anything.
I wouldnt bother doing a induction cleaning with Seafoam.
I never have.

 

Well on the bright side, my oil need changed anyway. Hadn't gotten to it since I bought the Disco a month ago. As per recommendations here on the forum, I used Rotella 15w40 diesel oil and a Wix #51515 filter.
