As above, my 2004 V70 has an oil leak which appears to be welling up around an injector. :-\
It's 100% oil, not diesel, and as far as I can tell there is a fitting kit available with clamp and seals for about £30, which I assume will solve the problem. I don't know anything about injectors though and have never pulled one out, but it doesn't look too difficult. :-\
Should oil be able to leak from an injector? ??? :-\ ::) ;D

Injector fitting kit linky. (https://www.ebay.co.uk/itm/GENUINE-VOLVO-D5-INJECTOR-CLAMP-SEAL-WASHER-FITTING-KIT-30650390-XC90-S60-V70/223186526236?epid=1217031729&hash=item33f6f4201c:g:htcAAOSwQg9bwII2)
Am I on the right track with this? ??? TIA! :y

Is that the oil filter housing bottom right of picture?
-
No it's the filler cap. I don't think that's leaking, as I've given the area a good clean and the oil reappears in the recess that the injector sits in.
The engine starts and runs fine BTW. :y
-
I thought it looked like the 710 filler cap , did you have a little accident ;D
could be the 710 cap seal leaking
I'd clean it all and check it's not traveling into the injector well from elsewhere

No. Unless it is an oil cooled injector, which means it would have separate oil pipes attached!!! :y

Cam cover gasket then...

No the injector sits in a recess of the cam cover, so the gasket is below that pool of oil. ;)
As you have to remove the injectors to take the cam cover off, I guess there is a seal or o-ring that seals the hole in the cam cover that the injector sits in.
This must be what has failed. :y
The only other place where it could come from is the inlet. Part of which you can see between the two injectors, but I'm pretty sure that is OK. :y
-
My guess would be that it's coming up the threads of one of the bolts highlighted here - that top one looks particularly suspicious, and I'm also suspicious I am seeing what looks like RTV on a mating face just below and to the right of it (down in the recess) - or maybe it's dried oily gunk?

RTV? ??? :-\

RTV? ??? :-\
Silicone sealant :y

Thanks Henry. :)
I'm also wondering if the breather is blocked, as I can clean it all up and leave it ticking over for a bit and there is no sign of leakage, but go for a short drive and that recess is full of oil again. :-\
-

I've got a two and a half hour drive tonight, so if we get a momentary break in the deluge today I'll clean it all up again, especially around those bolts and see what's what in the morning. :y
-
I’d agree with Dave, oil fill cap seal leaking under crankcase pressure, a good clean of the breather system may help and is free :y these diesels are a messy lot. I had this problem when the ringlands went on my Evo it would be worse under boost doubt very much if it would be pistons on your Volvo though they’re pretty tough on diesels.
-
Well gave it all a good clean today, ragged it up the road and this time could clearly see that the oil is leaking from the cap. :y
So good call Dave and Rae, many thanks! :y
I'll give the breathers a clean tomorrow and take it from there. :)

vauxhall do the rubber seal for the 710 cap as a spare part , it's very common item to leak on tractor juice engines :(
I wonder if volvo do the same as a spare , or if you have to replace the cap complete
or remove the o ring seal and back it and refit ,probably cheap enough to just replace the cap :-\
-
👍
-
A quick look on ebay shows the seal for £3.50 and a new cap for £25.
Strange thing though, even though I've cleaned it up a couple of times, there was no sign of oil coming from the cap, until today when I properly ragged it up the hill. :-\
I cleaned it up at the top and pulled the dipstick out a little so it could vent, before I ragged it back down the hill, and it was still leaking. I'll still check the breather tomorrow though. :y
-
Oi! Keep off my hill ;D
-
The cams are still flinging 710 about regardless of the breathers
at £3.50 ,I'd replace the seal

710? ??? :-\

710 . OIL
depends which way up you read the cap :y
is there a oil trap with PCV valve on these engines :-\
what year ?

Ah yes.... ::) :-[ ;D

I think so. There's a breather pipe which goes from the cam cover into a box, handily tucked behind the intake, fuel rail and injector loom. Can't see a valve of any type. I'll remove the breather pipe later and investigate further. :y
I'm a little reluctant to seal up the filler cap though in case something else goes which is more involved, but given it still leaked with the dip stick loosened.... :-\
-
clicky (https://www.volvopartswebstore.com/cars/Volvo/0/Engine/car-parts.html)
blown up part diagrams show the breather set up
but only you know what year :D
some diagrams showing a 710 separator with PCV valve about £30 ,obviously maybe cheaper elsewhere :y
select the correct year and engine will save you looking in the wind and rain ,if you have the same weather as here ;D
that said,the 710 cap should never leak 710 ,so the seal is poor
maybe due to duff PCV ,or just worn
-
Sorry it's a 2004 MY/Phase 2 V70. :) Can't see the D5 on that site Dave? :-\
So I've been out and had another look and as well as the pipe from the crank case to the oil trap/box already mentioned, there's a second pipe which goes from the box to the inlet just before the turbo at the back of the engine. There is what appears to be a sensor or valve with an electrical connection, which I assume is the PCV?
-
quick google points to 2004 ph2 is changeover year for M/Y 2005
D5 Dirty diesel 5 cylinders :P

PCV is part of the trap ,just a 1 way valve with membrane diaphragm
the electrical sensor or valve may be a solenoid :-\
plenty of youtube vids on how to test volvo PCV ,just select which annoying accent or language :D ;D
-
I've been out and come back clutching some jubilee clips, so will strip it down tomorrow and clean it all and then see what's what. :y
-
The electrical bit is to do with a heater element to stop freezing cold oil air mix going into the turbo inlet.

I would just try the oil cap seal first as there is always a fair bit of blowby with high compression diesels and the fact that the dipstick didn’t blow out leads me to think it could well just be the seal.if it’s the trap type system it can be a bit of a job to do properly and pipes plastic bits etc would most likely get broken too. I believe the whole lot can be bought for about £150. But I would try just the seal as why fix it if it ain’t broke :y.
293062977946. That’s the item number for the seal.
