valid point, but just from a risk/reward perspective and with the option for a free exit, I think I know what I'd do.

Tricky call.

2010 TDV8 HSE - ooo laa laaaaaaaaa
2007 TDV8 HSE - superb car and very reliable
============
2012 - dearly departed, sadly missed.. to return in late 2013 with a new TDV8!

Thanks RRS I think I will cry myself to sleep tonight and go put a deposit on a newer one tomorrow to cheer me up.......  2009 3.6 TDV8 HST

Ok, Just had a call off the "SPECIALIST" who said that the have concluded that there is a Turbo issue with the RRS. They have said that they want to put some Seafoam through the system to see if that rectifies my problem.

Does this sound worthwhile??????? I am dubious!!!!!  2009 3.6 TDV8 HST

The silence is deafening!!!!!!! I take it no one has any Seafoam esperience????  2009 3.6 TDV8 HST

Nope, sorry Personally, i would just book it in at a trusted dealer and ask them to ring me when they have found the fault instead of everyone guessing.

I think he is reluctant to send to a main dealer due to high rates so I think I may have to just get my cash back!!  2009 3.6 TDV8 HST

Ive Seafoamed the oil, fuel system and engine and I can definitely say it is worth it. The benefits are; more power in the low range or better said, restored power. The fuel efficiency also improved. Not by much but it was noticeable. Lastly there is the satisfaction of knowing that there is less Carbon buildup in the system. I can't vouch for any other engine than the 5.0 supercharged petrol.

It was all much easier than I thought. If anyone wants I can do a video the next time I seafoam the induction system.

When used properly Seafoam is a great way to clean your engine and fuel system.

Seafoam sounds great, but all the crap it flushes from the engine has to pass the lambada sensors and also through the cats...

So they go through the cats. I don't know how they work but I have NEVER had a catalytic converter clog or go bad. Has anyone? I've read this argument before and yes it makes sense but how big are these particles and does a catalytic converter filter it or just let it go through? Can anyone accurately answer that?... WAIT, I'll Google it lol

Ok I just googled it and basically the way a catalytic converter works is by heating up the elements inside so much that it burns off EVERYTHING and what comes out is just water, carbon dioxide and Nitrogen. Yes it looks like a filter but I will bet that any small chunks of carbon will just get burnt off and dissipate as a gas. The temps in there are in excess of 700 degrees Celsius (From what I saw/read) so that should be enough to change things around as it is intended to do.

I would say that Seafoaming a car that has not had the treatment done in 100,000 miles is probably not a great idea but using a fuel cleaner 4 or 5 times in a row PRIOR to Seafoaming the induction system is better. Again, MY opinion but it only seems logical to me to get rid of the easy to remove carbon build up in small steps before doing a Seafoam treatment.

Seafoaming is 'Italian tuneup' for people who do not have any opportunity to drive their car floored for 2 hours straight. Yes, it may remove some carbon buildup. In an engine that holds the oil inside the block because it is sealed with these deposits this will lead to excess oil usage and, eventually, to a catastrophical failure.
Seafoaming is OK if the engine is treated every 25-30k miles from new. I wouldn't recommend it for first use in a +100k miles engine. Regards etc.,

He's referring to catalytic converters when he mentions high temps and burning stuff.

As for this Seafoam stuff, it sounds a lot like RedEx to me.

Simplest thing is to just buy decent quality fuel. Adding stuff to the tank etc is mostly snake oil. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

I agree a lot of the stuff IS snake oil but let me rebut by showing you this video.

I'll also note that the treatment in the vid is NOT on a Range Rover or an 8 cylinder engine but it does testify to the power of the product. This for me was the deal maker and what prompted me to do the treatment.

Now then, I tried this method and it there was not sufficient product to treat the 8 cylinder engine. So I sprayed the contents into a small cup and used the vac line and suction method instead and it yielded far better results. My recommendation is to get the full bottle instead of a spray can to do a Range Rover 8 Cylinder.

I've not looked at how seafoam works, but I'll take your word that it raises engine temps etc. Surely though this's is worse than leaving any carbon deposits in situe ? I mean if the temps are that high they could make the carbon burn and pit the surface it is adheared to, not only that but as these lumps fall off they've got to go some where, so could end up trapped in piston rings and scour your liners. A well timed piece could get trapped between the valve and head, stick and then prevent the valve from closing properly until it is cleaned and rebedded.. the list goes on. I'll stick with a can of BG44 every couple of months or so.
