Focus 1.6 TDCI - Remove Turbo Internals and Blank Off Oil Supply ? - Ian Co

Just wondering is it possible to Remove the Turbo Internals on a Focus 1.6 TDCI, and blank of the oil supply, and run the car as a non turbo essentially ?

will this cause any other issues ? apart form bieng very slow of course !

If you do post the results here!

Because I've no idea other than it's a bad idea.

And it seems a bit extreme.

After all all you have to do to keep a turbo working on these is go back to the old ways and change the oil and filter every 6 K.

And I think you underestimating just how slow it would be.

And if the oil feed pipe has a tiny gauze filter in it, make sure its checked and cleaned.

I'm not sure on this but, I'd have thought that without a working turbo the ECU will light up the MIL with the possibility of the car ending up permanently in limp home mode.

While pondering on these engines the other day I wondered if fitting a decent remote oil filter in the oil feed pipe to the turbo might make the turbo last a lifetime rather than 300miles or so. The article I read on them indicated that the turbo failures are down to carbon deposits from the engine blocking the oil feed to the turbo. If I had one of these cars with a worn out turbo, It's something I would try.

well i have exactly that, i have been given an 05 which had turbo failure, new turbo fitted same old story its gone again, so as it cost me nothing that was my idea block the oil feed take the internals out of the turbo unit and hope for the best !

it wont cost me anything to try but i was thinkingthe ecu probably wont like it and end up in limp mode for some other reason.

any yeah i bet it would be like driving an old transit !

but its not really worth spending money on and its done 150k

You failed to ask the most basic question : WHY had the old turbo failed.

Most of them fail due to lack of oil supply - those carbon-clogged pipes.

If you'd changed the oil feed and return pipes, and given the entire block a good flushout and an oil change at the same time as the turbo, you'd probably have had a perfectly viable car.

Focus 1.6 TDCI - Remove Turbo Internals and Blank Off Oil Supply ? - Ian Co

Yes your probably right. but i already have two cars that work perfectly (because they are japanese) and i was given this for free, ive heard so many horror stories about these engines im not going to spend any money on it. even ford now recommend an engine change if the turbo fails on this car.

The point of it was would it work ? would the car run with no turbo intenals,and the oil supply blanked off ?

Im not bothered why it failed or what would fix it properly, would the workaround that cost nothing work ?

I very much doubt it would give any worthwhile performance without the turbo.

It is however, not that hard (or expensive) to fix. The problem is the little finger sized filter in the turbo oil feed pipe. Nothing to do with the pipes carboning up. Fit a new turbo cartridge (available from e-bay for £100). Dig the filter out of the oil supply pipe. Check if there is blow by on the injectors, if there is (carbon around them) remove them (OK, that might be easier said than done) and fit new seals. Remove the vac pump and clean the inlet gauze. Remove the sump, and rip the strainer out of the oil pick up. It should now run OK.

Turbo went on our C4 Picasso at 70k. Removed the turbo filter, and fitted a new oil pick up, but with the strainer in place. Got low oil pressure after about 7k (which ruined the vac pump). Removed the sump and cleaned the strainer - ran out of oil pressure again after about 7k. Removed the sump again and ripped the strainer out. Done nearly 20k since then without turbo or oil pressure problems (3 out of 4 injector seals have been done in the mean time). Had the filter been fitted in the turbo feed it would have knackered the new turbo long before we got to low oil pressure. Despite 2 low oil pressure events (the first at motorway speed) the engine is fine; so the base unit is fundamentally strong, it's just the ancilliaries that let it down.

And here's the filter in question, alongside a penny to give an idea of just how small it is!

Cheers but blimey thats a fair amount of work !

ECU MIGHT just compensate for the lower air by reducing the fuel injected, in which case you'd just be rather down on power. Depends how the control is done on that engine, which I don't know .

No turbo lag, which is nice. Cam profile might be wrong though.

If its REALLY little trouble to try it (?) then I'd be quite interested in your findings.

While you are at it, you might try to get some of the lost power back with gas injection, very popular in Australia.

A proper pro installation would be big bucks, but you could probably get a feel for it just by plonking a propane cylinder in the passenger footwell and bleeding some gas into the air intake. Diesels run way lean so fine stochiometric tuning probably isn't required.

Prior to leaving for Taiwan I bought a 40 quid diesel Maestro which would have been perfect for this kind of messing about. Really liked it, but my brother scrapped it a long time ago.

Interesing i just found this on the web elsewhere.....

Yes it can,BUT::::::

1-you have to block the oil supply pipe to the turbo; (VERY easy)

2-you have to remove the turbo and GUT IT: remove turbine/shaft,bearings,rings,compressor wheel,EVERYTHING;

3-Make a round plate(stainless steel is best) just like the turbo´s heat shield,BUT WITHOUT the big central hole,so that the exhaust gases do not go into the intake(or you would have a permanent EGR-not good)

4-re-assemble turbo,using that plate you made

5-mount turbo to car,using all the original manifolds,gaskets,bolts,plates,etc; if you have new ones custom made it will cost you A FORTUNE,in which case you would buy a new turbo in the first place;

Now it will run forever,BUT: you have a camshaft made for the turbo engine; camshafts for engines with no turbos are different(diff.timing/angles); so,go to the junkyard and get a proper camshaft; A LOT of work,as you can see; that,s why almost nobody does it; I have done it SEVERAL times (half of the times keeping the same cam) - over 40 years working in cars-,for people who really could not afford a turbo at the moment; BUT you will loose HALF of the hp; if you had 100 hp,now you will have 50 or so;

Oh, and NO smoke at all,since your turbo is now not passing any oil to the intake,since you blocked it off(you absolutely must,or ALL the oil will gush out in 30 seconds); why NO smoke at all? Because the electronics MATCH the diesel to the air; they(map or map)take care of that;

Yes,I have done it,did one just today,a 1998 Rover 200 2.0 TD; has a Garrett GT 1549 turbo; poor girl has little money,will bring it back(?) when she can to install another turbo ,

I'm surprised someone hasn't come up with an oil spinner kit for the Diesel of Doom, system as fitted to industrial and lorry engines, it removes almost all the nasties in the oil, some enterprising individuals have fitted spinners to their own Diesel cars and pick ups, not to extend servicing but to keep the oil clean.

Perish the thought any car manufacturer got wind and started retro fitting such things or some suit in marketing would come up with 60k oil service intevals as a sales pitch to fleets.

My 1964 Honda motorcycle had something similar driven off the crankshaft-also fitted to a number of car engines in lieu of an oil filter.

I had a Fiat 850 with a centrifugal oil filter on the crankshaft. Removed it once for cleaning and it had a 10mm thick coating with the consistency of a pencil eraser on the inside with tiny metal particles embedded in it.

Seemed to be an efficient filter.

Why does the turbo need its own oil filter? It looks as though it can easily be more of a hindrance than help. Isn't the main oil filter good enough? If not, why not?

One thing I never see advised for oil change procedure (and something garages will never bother to do) is to jack the car so the drain hole really is the lowest part of the sump and leave it to drip brown gunge for several hours, preferably overnight, before renewing the oil and filter. I would think this is especially useful advice for those with engines requiring the fuel of satan.

Well maintained cars don't get brown gunge or sludge - it's the others that do.

Surprisingly cheap, though that's without the plumbing.

All the Honda motorcycles that I had circa 60's manufacture had one of these centrifugal filters & nothing else.

The oil used to come out of a drilling down the centre of the crankshaft, presumably after lubricating the big ends.

It discharged into a small cup like cylinder bolted to the crankshaft with a removable end cap for cleaning.

All my bikes were secondhand so cleaning this was a priority on ownership.

They were always neglected & you could usually scrape out at least a 5mm thick crust.

Oil changes were 1500 miles then.

I think Honda started using paper filters late 60's & unfortunately the centrifugal one was dropped.

Bean counters even in those days.

Most of the motorcycles (as opposed to the commoner scooters) here have engines based on the Honda CG or CB 125, which have a centrifugal filter. The snag is that they have to be cleaned out, and that tends not to happen, especially here.

Its on my to do list for a Sym Wild Wolf I acquired a while ago. Probably never been done so I expect it'll be full.
