Whats your thoughts on the terra clean business?

anybody had it done?

is it as good as they say?

Caddyshack

Had it done on my m135i and I believe it was better. The theory works.

Carlos-Titx

Mate had his scooby done and said it was great after.

Need to get my jeep done.

thinking of getting my 3 series done, dpf warning has gone off and may just need some help cleaning the engine out after some heavy mileage it's done.

Carlos-Titx

I've 140 k nearly on my jeep so probably worth doing.

Just smash the dpf out!

It's a load of balls.

A friend had a Diesel Pug done, took the head off 40 or 50 miles afterwards and there was still a load of carbon stuck inside the engine.

That's because the process doesnt actually send the miracle cleaning fluid anywhere that actually needs cleaned. Even more so on a diesel.


You'd be better off throwing some metal balls into the fuel tank, then some tablets and finally sticking a load of magnets to the fuel lines.

I got quite involved with euro 5 emissions faults on the Daf xf105 with Daf technical. We had a fleet of 5 that was using yada air one ad blue. It was glazing the cats over and bring the eas warning lights on. And at 5 grand a cat they don't just sling them on lol. 4 of them ended up with cats the other had had something called nano irons tipped in with the fuel. It's very very minute particles that sort of shot blasted the cat surface. Out on road test watching the nox levels before and after the cat it took little time for the stuff to bring the levels after back into line. Dafs worry was if it would damage the 6 fuel pumping units the injectors or the coating on the cylinder walls. I've not seen or heard of it used again.

Exactly, just think of the effort it takes to get carbon build up off valves, no miracle fluid is gonna help with that!

stevieturbo

Especially on a diesel or direct injection engine where the fluid never even touches the valves lol

I personally think it's just an expensive fuel additive u could pay £10 for and chuck in the tank. Used to see good results from the forte additives when I had my garage. But then I'm no expert on terraclean but I'm always very sceptical of these things as always seems like a money spinner

Carlos-Titx

From what I looked at a local 'cleaner' (is that the term?) he said they disconnect the fuel and plug their stuff in which will run the engine but cleans everything the exhaust gasses come into to.

I would love to see a before and after of an egr valve on a high mileage diesel or something else that gets clogged easy like breather pipes or something????

But reports I've seen rate it. It is a facebook page for local guy to me.

Be good a proper test. Dyno before and dyno after.

Hit reply instead of edit like a moron.

It works but the carbon builds up again within 10k

Fullflush

I took my EGR valve off once and fuck me that stuff on the inside is insane to get off

Carlos-Titx

Carbon build up couldn't be No where near what it was surely?

Suppose though if it makes a big difference you could use it as a service interval every Few year??

stevieturbo

it does not work, it does not come into contact with anything in the intake tract on a diesel, so it is impossible for it to clean anything there

You'd be far better spending your money on some Greek lottery tickets than wasting it on Terranonsense

Bailes1992

It does work, I've seen it first hand.
If you have a fully operational EGR then the chemicals will come back around and clean the intake too.

I saw one having a DPF clean as well as a normal Terraclean and there was loads of crap ooozing out of the exhaust.

stevieturbo

DPF clean only may be a different matter.


Anyone who thinks that it does clean the intake etc really needs to take a look at the parts after the process.

Yep, they'll still be filthy. And if by some miracle all the crud did get removed from the intake..where will it go ? Straight into the chamber and out the exhaust blocking the cat or DPF.

Really...save your money for something worthwhile, like tax.

Stevie your missing the point, the cosworth isn't a diesel has not got any gay egr valves ect. From what I've read so far on This page, the feedback from people with PETROL powered cars suggest that it will work on the OP's cosworth.

stevieturbo

And as I've already clearly said, as this flui passes through the fuel system, which injectors directly to the back of the intake valve.

So it is physically impossible for it to clean anything in the intake prior to that.

And the rest shouldnt have any real dirt issues in the first place because the fuel would be keeping it clean

robvirgo

on diesels try the bg 234 product, ran it in a few diesels and makes a big difference,stuck petrol version in the 3dr cossie but difference not as noticable...

robvirgo

sorry bg44

How does the Terraclean go through the EGR?

The whole thing is utter snake oil. The original Terraclean was a petrol treatment they discovered by mistake. They then realised that there was a big market for diesels so concocted some stuff for the derv market, but it's completely different from the petrol treatment.

I had my 140K mile Mondeo diesel treated - and was the perfect candidate as I'd been logging my mpg every tank ever since I bought the car (can't recall the exact figures but IIRC it was over 10K worth). The Terracleaning (carried out by their 'expert' as it was for a mag feature) did absolutely nothing, the car drove exactly the same, and the mpg was completely unchanged by the process.

Terraclean, and a bunch of similar treatments rely on the owner wanting it to work, and wanting to believe the hype. Save your money and spend it on a service instead!

BG Induction cleaning process is FAR better. I wanted to become a dealer for both but once I saw how Terraclean worked I dropped the idea totally and went with BG.

Harris.

Then your facts are way off line,i know 3 Rs4 owners that have had it done due to the nasty carbon build up problem with these engines and it does WORK but as said 10k later its back , so advised to do it every 25/30k .

Caddyshack

I read a lot about the RS4 when I was thinking of getting an R8 as they have similar problems, I read a lot of good reports.

Harris.

Mines been spot on so far , had it nearly a year already with no dramas .


I will get a carbon clean done on its next service . Bhp level drops to around 395 and once done rises back to 414 bhp after reading many things about it .Mainly Due to being a high Reving V8. they don't like low down revs around town and found giving it a good blast clears it out .

Ronnie Scott

could u enlighten me further on the BG induction cleaning stu?

Adam-M

So the conclusion is it works on a petrol car but not a diesel so if you want it to work sell the diseasal and buy a petrol. I'd of thought petrol would of been a good cleaner anyway.
