Fuel Leak using veggie

[johnsiddle]

Hi Matt

I filled it up then took the heater pipe off and put the hose on until water came out of the heater pipe also the filler.

Did a short run and all seemed OK but when parked it I could hear bubbling in the expansion tank, some water ended up in the tank but it didnt overflow, so I went for a longer run (about 2 miles) thro the village, the temp went to hot.
I limped home and left it for an hour and checked and there didnt seem to be any water left.

I refilled and started it with the filler off and there was a constant flow of air bubbles. I parked it up and left it, when I started it this afternoon, it having been left all night, I took the filler cap off almost as soon as I started it and WHOOOSH loads of water shot out.

It apparently had a new head fitted about a year ago (supplied by Milners and fitted by a garage in Anglesea) but it would pressurise the water from then on.
When I took the head of there was evidence of blowing into about three waterways, but no serious damage. So I fitted a new head gasket, I did have to get a longer head bolt cuz the thread pulled out of the block (bolt 12 I think).
I had high hopes for this... but now?????

Getting there. 2.4TD

Well we have a bit of a result.
This afternoon I heated the engine up then removed the rocker top and got another quarter turn on the head bolts and BINGO no more overheating.

Did a 4/5 mile run and the temp stays right in the middle. I also have heat coming from the heater ( something I didnt have last night)

Just one smallish problem left, the Turbo light does not come on when driving although it does come on when the ignition is turned on.

I can not see any wires on the Turbo so any ideas???

Also I appear to have a spare connector a sort of beige or brown colour, it is in the vicinity of the injector pump but I can not see where it plugs in.
Can someone with a 2.4TD have a look and see if they have a spare if not where does it go.

the turbo pressure sensor is on the side of the airbox, the 'spare' plug is probably that.

Spare Connector

Thanks Tony, I will have another look. I do have a black connector on the top of the air box which is connected.
This spare one has'nt got very long wires on it so I doubt it could stretch as far as the airbox unless it is underneath.

Spare connector

Whilst looking for somewhere to stuff the spare connector I found another one spare.
Eventually found that they both plug onto the injector pump under the top connector and above the capacitor.

However the Turbo light still does'nt come on. The turbo is spinning, the car seems to drive OK with absolutely no smoke, not even a whiff.
It is running on about 60% veggie.

The only sensor I could find is on the top of the airbox in a rubber grommet, is that the turbo switch??? Just looks like a black plastic prod.

Glad it's running ok and hopefully cured, not sure which bit your on abaout but there is a vac connector on the side of the air filter box, stick a pic of your one on and i'll check it against mine

road test

Did a 14 mile road test this evening, and all the time the temp was in the middle.
When I arrived home there was some bubbling in the expansion tank but it stopped quite quickly.

I am a bit annoyed about the Turbo light not coming on and was wondering where the turbo sensor is, incase I havnt reconnected it.
Any idea's.? Matt said it was on the airbox, but all I could find was the connection on the top. I pulled the sensor out of the rubber grommet and it just looked like a small plastic toy rocket, it looks more like temperature sensor than pressure .
Anyway disconnecting it did not bring the light on neither did shorting it out.

Going back to my spare connectors, the strange thing is having them connected or not made no difference to the running of the engine, they are connected to something in the injector pump.

on the 2.4 the boost pressure sensor is behind the back of the airbox (not actually attached to it), low down on top of the inner arch, (shite description i know, but...).

It has a vac pipe that goes into the bottom of it, the other end goes off to a plastic filter/valve on a bracket above the throttle body, which then has a L shaped hose coming out the other side and going into something else. This L shaped pipe comes off or splits fairly easily at the other end, but a split/blocked/leaking pipe anywhere among that lot would stop the turbo light coming on.

Turbo Light

Thanks for that NeroI think I know the bit you are talking about.
Would one of you try something for me.
On the airbox top there is a sensor of some sort as in pic1 ( which is what I thought was the turbo switch ) it is pushed into a rubber grommet into the air supply.
Would you pull this sensor out with your engine idling and tell me if there is a vacuum at the grommet or is there air pulsing out.
Then rev the engine and see if it changes.

On mine when idling air is blowing out and when you rev it changes to a slight suck.

Turbo Switch

Been and had a look under the bonnet.
Do the attached pictures look correct, have I understood you correct, ie: this is the Turbo switch???

[gwh200]

yes thats correctly piped, and the pictured turbo sensor is .....the turbo sensor

[johnsiddle]

Thanks

Thanks mate.
I will have better play with it tomorrow.

[gwh200]

your welcome.

mine played up a wee bit, till i superglued the connector on the sensor back together

Turbo Light

It seems that my pictures of my piping was incorrect.
Remembering what Nero said about a plastic filter I checked and found I had crossed this pipe with one that goes down the side of the head. Corrected this and all is working now.
Thanks guy's.
I still dont know what that sensor in the airway is... But who cares..

All sorted now then well done mate, not sure what that "sensor" is either unless it was to block up the hole caused by the grommet!! i expect theres a warning light on the dash somewhere that says "sensors fell out the grommet" opperated by a sensor failure sensor or it could be a choked air filter sensor buggered if i know,
anyway you goin on about turbos made me think!! think i'll ask
