In this video we dismantle and diagnose massive engine failure in a 1.9 TDI PD. In the last video • Stop Being Ripped Off ... we converted the Caddy to run on veg oil, after testing it for 500 miles, fuel leaked into the oil.
This filled our crankcase and caused problems. By examining the engine's tandem pump and camshaft we can see how bad the damage is. While we are at it, and have worked out how to remove the valve cover, we go on and assess the condition of the intercooler, unit injectors, ERG valve and turbo.
Hopefully this video will be of use to you if you have a problem seal in the tandem pump, or need to take apart a pump duse engine to find faults.
The engine here is a VW BLS which is also very similar to engine codes: BJB,
BKC,
BSV and
BXE. These appear in lots of VW, SEAT, Škoda, and Audi cars, but this one's in our Mk3 Volkswagen Caddy.
Quick Links to dismantling and assessing certain engine parts:
00:00 Into to Fuel in Oil problem.
00:30 Draining the oil from the sump.
01:32 Removing the sump pan to asses the condition of the engine (and fix the leak!)
03.05 Checking the turbo to intercooler pipe.
03:53 How and why check the tandem pump?
05:08 Full Tandem Pump teardown / dismantle.
07:37 Camshaft inspection and assessment (including cover removal)

Hi Mr. Elbow, just wanted to let you know that I had the exact same issue with the same engine and tandem pump, but completely unmodified. I drained the oil to find about 8 liters of mixed diesel/oil in the catch can. I searched youtube for an explanation and found only this video. Rebuilt tandem pump with new gaskets and she's fine now. Funny thing, I found no other cases of this happening but yours, and I've been watching and learning from your chainsaw mill videos for years!! Small world :)

Hugely rewarding to both locate the mechanism that failed (tandem pump seal) and recognise why it failed, (over enthusiastic lift pump). Pity you then found a worn cam - though I presume the engine had been running OK prior to the tandem event. With it all in bits the temptation to replace the engine must have been strong though you might have gained a few years use if you had "just" fitted the tandem pump seal kit and put the old engone back together...

Hey Lucas, great to hear from you. Thanks for your kind words - though I'd never claim to be a mechanic - more like someone who tinkers with oil when pushed into it ... lol. I feel you hesitation on big end work. I have an older friend who often tells me about the time he rebuilt and changed big end bearings on a car, on his dads farm yard, worked for an hour or so.... He forgot to put in some kind of minuscule oil channel or something... It's probably why I plumped for the whole new engine in the end - I kinda suspected I may have bent a connecting rod with all that oil/diesel getting into the cylinders... Anyway, best of luck if you have a crack at it, let us know how it goes. Peace, Bongo.

Cam doesn't look bad at all compared to what i have seen in the past. It's normal wear, I would have just got the seal kit for the pump and called it a day.. next time you pull an injector out, twist the injector back and forth a few times and will pop out with almost no stress.

FYI veg oil dries out / makes rubber stiff. So if that seal that blew was in contact with veg oil and is made of rubber then that will probably be why, they get hard and stop flexing so cant do their job of sealing anymore, or at least it could be a contributing factor along with your lift pump setup.

Determine the cause of the fuel contamination. Possible reasons include: Faulty fuel injectors or carburetor: If these components are leaking, fuel may enter the cylinders and eventually make its way into the oil. Compression ring or piston issues: Problems with the engine's internal components can allow fuel to bypass the combustion chamber and mix with the oil. After addressing the issue, monitor the engine closely. Check the oil regularly to ensure that fuel contamination does not recur. If the problem persists or if there are signs of ongoing issues, seek professional assistance.

Hello, I own a Kia Cerato 1.6 crdi 136 HP vehicle. My car is at 86,000 km. Diesel is mixed with the engine oil, the oil level is constantly rising. There is no problem in the operation of my vehicle, the idle is normal, there is no noticeable black or white smoke from the exhaust. It works immediately with a single start in the morning, there is no problem. The technician said it could be the DPF and he removed the DPF and cleaned it in the machine. The DPF was around 40% full, but it was still cleaned. But that was not the solution either. Engine oil level continues to rise in my vehicle. I think there is no problem with diesel injectors because there is no indication of injector failure. The vehicle engine has a timing chain. Could it be from the high pressure diesel pump seal? Or what could be the problem? Could you help? Have you ever heard of such a common problem for vehicles of this segment? Urgent. Thanks in advance

Great video worth the wait(suspence)Your EGR valve is quite clean.My 1.9Tdi was smoking and lumpy on cold start then running well after 45 seconds/I last cleaned EGR when car was purchased nearly 3 years ago but happend to check it last week as on holiday and it was 85% blocked again so cleaned and car goes like a rocket again.You are not saying veg oil caused the failure but the fuel lift pump on the diesel circuit which is interesting.Can you list the pressure of the pump you eventually fit I suppose if you can find the pressure of the stock VAG in tank lift pump you should match it.There is also a modification people do to PD engines running veg they modify the in tank lift pump with a by pass hose kzfaq.info/get/bejne/f8WZdcKHtcfYkZc.html so any excess fuel just stays in the tank they generally use this to improve the fuel feed on non Tdi engines like mine with a dedicated fuel injection pump(non PD engines)Last year when I was researching converting PD enines I did speak to a chap via eBay who said he has successfully converted several PD engines using a similar method.The lift pump situation on PD engines has been my stumbling block (switching and type of pump to use )hence the interest in yours channel.Keep it up.If you seen my channel I use a loop system on the feed to my Bosch pump(non PD)so the pump has less work to do as it is not constantly drawing fuel from the tank then sending unused fuel back again.I think If you get time to watch this 2toc video at 3mins 50 seconds he point out a loop system and I believe its on car with lift pumps? kzfaq.info/get/bejne/nMp4abdoz67SiZ8.html Does he use a lift pump with a pressure relief valve?do such things exist?I have seen lift pumps on ebay that are veg oil tolerent.Good Luck Great Channel.Once you find a cheap source (or free)you could look at running your heating syatem at home with a veg oil burner?Start on heating fuel then once warm switch to veg thats heated from the hot water via a heated fuel filter or just a heat exchanger.?Heating oil is about 50p per litre?

Hi Simon, Great to hear from you again. I hope lockdown isn't so bad for you. That's really interesting to hear about your ERG experiences. Just saw your e-mail with the pic - I see how that would choke the engine... I have heard people say they don't play nicely with veg oil - any truth to that? Yes, as far as I know the veg oil itself didn't cause any of the problem... I think it was mostly the lift pump I fitted that caused the seal to go, although those seals do just fail anyway occasionally (or so I hear). The pump I have fitted now is this www.demon-tweeks.com/uk/facet-interrupter-electronic-fuel-pump-243226/ Not the cheapest, but recommended to me by a few people. When I tested it, the pressure doesn't go too high, no more than 1/2 bar, but flow rate is a touch higher than the stock lift pump. There are such things as pressure relief valves - and I thought there was one in the tandem pump itself (so I guess I was wrong or it was malfunctioning). I saw a few for sale at demon tweaks - but none seemed to be designed for diesel fuel... I'll watch the 2toc vid now. Peace, Bongo. PS interesting idea with the heating oil.. Will need to find a good free supply first, with is not happening any time soon with lockdown..

I see the closed loop system you are talking about. I wonder if overheating may be a concern? I think the tandem pump heats the fuel quite a lot, and maybe relies on incoming fuel to cool its component parts? That and the problem with polymerising in the small channels of the engine head? It's all hearsay and speculation though... I'm unsure.

EGR glogging with veg is probably the same as with diesel just check the EGR every 12 months,Dont forget diesel is dirty fuel as you will find out your heated veg oil filter element will be super clean even after several years if youve filtered used oil well whereas a diesel filter will be filthy after 12 months.
