so its a wiring fault then, you have proved its not injector why are you going on a compression test before sorting wiring out

Hi good morning. DF041 Cylinder 2 Injector Circuit Open circuit Intermittent DF 056 Master air flow sensor Short circuit to ground or open circuit Intermittent DF056 Mass air flow sensor Offset at min limit Intermittent DF025 Pre- postheating unit diagnostic line No status Permanent When I got it started yesterday. I used quick start. When conected intercoolant pipe back on car died. Done it a few times

[*]It say on Dialogys to check connector c is that the bottom connector on ecu or the top.
[*]Also say I must run test 1 Injector Test ? Not sure what that is. Thanks

That's what Serser69 suggested.

Ok can you please help. Not sure of following
Grey 32 track connector C. Is that top or bottom . What is track G4 ?

 

[serser69]

if engine have large blowby on oilcap or pvc valve,how that cant be mehanic failure ? piston ring or valve seal ?

 

[ours2012]

he needs to sort electrical issues out first to see whats up..
How will a compression test help that

 

[serser69]

you are right, but "vice versa"

 

[Ian John Sinclair]

Thanks guys for your help. I will check wiring then sort out the compression test. On a petrol you do a wet and dry is that the same on Desiel

Hi all again.
Stuart I tested the continuity on the grey and cream wire on plug c and plug to injector all good. I get continuity. I started it again still loud noise. White smoke out exhaust and pvc valve. I had to start with quick start every time. When running and I put intercooling air pipe back on motor dies. If I leave off monitor runs for about 3 min idle and dies. Smoke also coming through inter cooling pipe. I am sure from breather pipe. So looks like I am going to have to do compression test. How do I do the compression test please help

There is a product on the market in spear shop that claims to seal steam seal. I think it also seals piston rings. How good is that do you know?

If I got water some how into the oil chambers well taking the head off. I did disconect the water thermostats housing to let water out before taking head off to check valves. I did not take the oil out. If a small amount of water got into oil. Could this cause the white smoke. And the loud noise.The oil on dipstick is not mayonnaise ish. No white mayonnaise on oil cap. Its synthetic oil. ?

Please help ?

I also did not change the head gasket. It looked new

struggling to work out how an electrical fault will be from inside the engine..


List the fault codes as they appear ,,

Lets see if we can work out whats possible/probable cause before you strip down half your engine..
Pull the breather pipe off the turbo/air flow , start the engine and read/diagnose ..
P.S. What are you using Ian, Wurth, Or Deplhi?

Thanks Stuwart.

I am using Delphi. Will try the breather pipe thing and come back to you. Thanks

Hi Good morning all, Stuart I hope you had a great Christmas.
Have not got a chance to do the Breather pipe disconnect and restart yet.The battery is flat.
I have been googling and came up with this Article
Three Reason for White Smoke.

1.Clogged Fuel Filter
2.Incorrect injection timing (due to a bad injector pump, worn timing gear,or a compromised crankshaft key-way)
3. low cylinder compression (due to compromised valves,cylinder glaze,or a worn or sticking piston ring)

I was wondering if it is not point number 2.
I had a problem with the Key-way on the Camshaft pulley. There was a whole in the pulley wheel, by the key-way. I noticed on a picture from a second hand Pulley that there was a pin, through the pulley for the key way. So I made a new one and inserted it into the hole. It helped for the giding of the pulley to the camshaft. I tighten the pulley as much as I could with the head off, holding the head with my feet, not so tight but I thought I would be able to tighten better once head is on again.I do not recall tightening the bolt again. So I am not sure if the pulley has moved or not. It was as tight as I could tighten it well head was on the tile floor.

I want to take off the bolt and see if the wheel has moved or not. Can I use the key-way Gide on the Camshaft to line up with the mark on the side. How will I know if the head is at DTC ?

 

[ours2012]

If your valve timing is incorrect then you will NEVER get rid of the white smoke.
IF in doubt.... Would be checking that before stripping anything down

 

[Ian John Sinclair]

Hi Ok this is beating me.

I have checked the Cam pulley and took it off. It still lines up with mark and the pin in the pulley is still in place, I have tightened it to 60nm, IS THIS RIGHT?

So I have done the Following.
1.Took off head and Set TDC. Valles on Cylinder 1 and 4 all closed. Put head back on with same Gasket and bolts
2. Checked and set in timing belt, all marks line up.
3 Changed oil from 15w40 normal oil to 5w40 Fully synthetic. Was not smoking with old oil, but now does ???
4.Dash said check injectors, Scan says Check Cylinder 2. Took out and cleaned injector number 2 and cleaned out noses all were blocked , sprayed Quick start and could see 4 holes spraying. Put injector back in, Started no difference.
Swooped injector 1 and 2 around, still same problem.
5. Got Molly Diesel Purge and ran car on 1l, after about 10 seconds, loud noise went away, clatter noise and smoke, then after about halfway through the Purge it started all over again. Carry on till purge almost finished, did not run dry.
6. I can see air bubbles So I loosened Diesel fuel pipe on rail, to get air out, but car just died.
7. Ran Car again cleared scan codes and still Cylinder 2 comes up.
8. Get car running and again Loud noise, White smoke and oil out of PVC valve. Took Breather pipe off and loads of white smoke comes out breather.
9 Strayed Quick start in air intake pipe from inter cooler, get car started then when I put Inter cooler pipe back on car Dies. Start car and runs with out pipe for about 2 min then dies.

Have not done compression test yet, Will Start Car tomorrow and Run with breather pipe off turbo and take scan.

when cylinder 1 and 4 valves were closed, did the timing mark on the sprocket line up correctly to the hole in the Casing
You are checking that the hole in the casing is TDC for cam?

When I had the head off and moved valves to closed position . 1 and 4. The slit in the camshaft is at 12 o clock. When I connected the pulley back on. Pin in slit of camshaft. The sprocket timing mark lined up with Mark on casing. .
You had another way to make sure the head was at tdc by taking off rocker cover. I can not find those steps. Would like to make sure it's right.That way

 

[serser69]

camshaft sprocket/gears 60 Nm

 

[Ian John Sinclair]

Thanks serser69. Do you know how I can now check the camshaft, to determine if its at TDC ?
