Thread: TD5 Oil in o verflow tank

Fingers crossed for an easy resolution!

so haven't had a chance to look into it yet.
drove it back from grafton, nursing it all the way.
just took it down the shops this morning after cheking cooland and oil levels are ok.
when i started it at the shops the oil pressure light stayed on up to about 2000 rpm. on again at idle. checked oil, not low in oil, so its losing oil pressure somewhere. will wait a bit and see how much oil has ended up in the water.
still undecided on oil cooler or headgasket until i start pulling it down tomorrow.
possibly both ?
has symptoms of oil cooler leaking and headgasket leaking or cracked head. was pressurising the coolant system on way home from grafton. every half hour or so the low water level engine saver would alarm. stop, bleed it up again and away i would go, although it lost very little if any coolant. so really not sure.
all ponderings until i get it in bits

G'day Roscoe.
Mate I hope it is the cooler.
I'd be pulling the heat exchanger out first. If it is just the core that needs replacing, try ARE in Brendal for a price ( are.com.au). When mine let go, thecheapest price I could get locally for the assembly (only way it is available) was ~$900. They made me a replacement core up for ~$600.
Hope this helps.

When my oil cooler went about 18 mths ago, the wifey and I heard a sort of running water sound from the dash area.

It pumped a fair bit of oil into the cooling system, not long after it was fixed I blew a few (6) coolant hoses over a period of a few months so watch out for this as they might have been overstressed.

yeah, i have just replaced one of the coolant hoses a week before this trip as it was looking a bit sad, should have seen the warning signs then i guess.
the oil cooler bypass hose looks a bit ordinary, and that's a fair sing the cooler is the main culprit. oh well, cooler out first thing tomorrow and then i can go from there.

soooooo....................
dropped the coolant, lots of oil. took off turbo, oil filter housings, and then oil cooler. then realised i forgot to undo the large 28mm ? bolts on the housing that hold the cooler into the housing before i took the housing off. "damnit" says me. they are ****ing tight. will need to put the housing in the vice to get them undone now. line it all up and put the socket on the bolt only to find it a tiny bit more than finger tight. as with the second one. so my guess is the o-rings has collapsed allowing the bolts to be a little loose and hopefully that is where the oil is going as the cooler still looks in good nick.

my only concern is does this mean its gotten really hot for the o-rings to collapse ?

If it's the oil cooler core paddocks have them for $225 + postage, Bob

oil cooler is in being pressure tested, but all looks ok from outside. the orings on the other hand look not so good. hoping its just the orings.
