Thread: A question for the Td5 Guru's if I may

It also drops a few drops of fuel from around the fuel filter overnight. I've only noticed this over the last couple of nights because I've been parking it on clean concrete and not on the grass.

Mark, might be worth checking the air bleed valve on the fuel filter housing.
Might be the source of your hard starting.

Paul.

The block that the fuel filter screws into can get porous and as mentioned there is a valve in there. Check if the filter block looks damp. Then the fuel pressure regulator on the rear drivers side of the engine. Check for diesel there also. If your washers need replacing the fuel will be in the sump so you should be able to smell that on the dipstick or see the level is up.

Also ensure that there are not 2 'O' ring seals on the fuel filter. I know of a case where the old seal was not removed when changing the filter and after a while with 2 seals fitted they began to leak.

Yep, I've seen this too.

Well it looks very much like I'm facing two issues here.

The fuel filter is leaking around the top where it screws in so a new filter and o-ring should fix that.

The other issue is a bit more serious. After a few high mileage days the oil level has risen ever so slightly therefore washers and O-rings are well and truly in the frame especially when coupled with the other symptoms.

Looks like those incompetent fools that did the head replacement failed to fit the washers and O-rings properly (five times). I'd dearly love to take it back to them and tell them to fix it but they've proven that they can't be trusted to do the job right. There's a trusted indy in Morwell who I'll take it to and while he's at it he can do the oils and filters as well.

To say I'm annoyed about the rising oil level would be a considerable understatement.

Thankfully the FPR is fine. Dry as a bone around there. The fuel is very slowly weeping out where the filter screws in. I've loosened it and re-tightened it but the slight weep is still there.
