Todays problem (again)

[transitgeoff]

Hi, well here we go again!, todays problem is on a year 2000 Xreg 350 2.4. well where do i start well i bought it from ebay as a non-runner, when i spoke to the owner he has had nothing but agg with it ,he says being slow was the original fault so it went into a Ford agent where it was fitted with a brand new fuel pump which is evident, then he says he had some bleeding problems where it went back to Ford dealer for a new filter and housing, then back in again for injectors well hes spent a fortune i bought it not running so i towed it round the corner from the guys house, bled it towed it and away it went well i started driving it home and it seemed ok,if a bit sluggish when all of a sudden the temp guage shot into the red smoke was pumping out the exhaust like a smoke screen and it sounded like someone emptied a bag of spanners into me engine, i pulled onto the hard shoulder where it wouldnt turn off so i had to stall it and get the RAC to recover me, i think the knocking was a diesel knock rather than a mechanical knock,,any ideas anyone??

IS IT THE FOO FOO VALVE

[transitgeoff]

could be but ive lost me chopsticks

[chrisuk]

Lots of smoke, mmmmm turbo failure pumping hot oil into engine and could be the reason it wouldnt trun off, dont want to really know how much you paid for it, if its just the turbo Im sure you can sourse a 2nd hand unit somewhere, I too have the same van, just finished today insulatin the back and its has made one hell of a difference, they may be a bit on the slower side but the rear wheel version does feel alot more firmer on the road, Im less likely to push it hard due to the lower power rating and it will prove its self when it tows my caravan shortly...

Best of luck

geoff thats a tricky one mate! sounds like its running on its own oil maybe, is it a 125????? every time i go to fords they allways have them in for new engines! i hope it isnt to bad mate!

[transitgeoff]

cheers Mark,its a 90ps, bought it from the guy saying its done 70k miles but he gives me the mot with 6 months remaining saying 136,000 !! the turbo thing sounds good the only thing is the temp guage, that shot into the red, even though i dont beleive it actually was over hot

[100ps_drw_hicube]

could be a bent mot we bought a vehicle once with 12 months mot when we studied the cert the chassis no was about 5 no's out

[chrisuk]

Pity it wasnt a dealer as there is a law that is strictly enforced, any 2nd hand sale is automatically covored by a 1 month garrantee

[MrMPuk]

I can't see how as he bought it as a non runner!

[Nighthawk]

Whats the oil level like ?


The temp sensor doesn't read water temperature directly, it's quite possible that increased RPM and compromised combustion could create high cylinder temperatures and confuse the sender.

Without seeing it when it does it though, it's hard to say for sure.

Does it sound like an old sherpa and want to cut out ?
scan it for codes, if it has P0149 and P1564 you could be looking at a defective injection timing control solenoid. Again without seeing or hearing it i'm not 100%

[transitgeoff]

Hi Mr Nighthawk havent touched the thing yet its still where the RAC left it, i will have a butchers in the morning ,havent checked it for codes either, where is the injection timing control solonoid situated? the engine sounded good but was light to quite heavy smoking all the time i was driving, i was driving it very gently and it sounded fine, until i went to overtake the caravan that was being towed by a snail then diesel knock central and my own personal smoke screen machine had to stall it in the hard shoulder on the M2 as it wouldnt turn off, i tried to start it this morning , nothing, must be airlocked again

[Nighthawk]

The injection control solenoid is on the back of the pump below the injector pipes, if you wouldn't turn off I'm doubting that as being the cause.

Have you had chance to check the oil level yet?

[transitgeoff]

going outside now ,to check level.

[transitgeoff]

your on the ball oil about 6 inches above max, very thin do you think its full of diesel??

[Nighthawk]

Exactly

My guess is.......get a seat handy cause this might go on

Somewhere along the line a botched repair has been carried out.

When the original fuel pump was replaced, i'll bet the system wasn't cleaned out to remove the swarf from the pump. That swarf is allowed to circulate in the system where it contaminates the injectors causing them to stick.

Compression from the cyinders forces air up the injector.....along the pipe and into the pump, from there on it blows the front seal on the fuel pump and allows diesel fuel to leak into the engine oil.

The level increases and thins to the point of failure, the turbo gets hold of it and away it goes doing it's F1 wanna be impression.

The air ingress into the fuel system is also enough to cause this bleed to start issue on a cold start.


The only sure way to nail this issue and make it go like a good un again is

Replace the pump and injectors
replace the leak off pipe (curly one)
replace the filter element

Drain and clean the tank and wash out the tank. you should also wash out the plastic fuel lines and the filter head while it's pulled apart.

The injector high pressure pipes are supposed to be replaced but you can get away with that.....just give them a blow through though


Before you commence the repair.....pull off the fuel filter element and cut the top off it using tin snips, carefully lift out the inards and see how much metal is in the bottom of it. Don't use a hacksaw to open it or it'll put more swarf in there.
Or.....if you can't be bothered to cut it open hold it over a clean container and undo the water drain as quickly as you can. most of the crud will leave the filter but some always stays inside.

Wait for daylight though m8......it's a bit chilly out there
