Oil in coolant

[460cixy]

Looking At a cheap high mileage d3 with 2.7 diesel that's developed an issue with the engine oil getting in to the coolant I'm thinking it may be a oil cooler problem and a cheap easy fix is this common or do they have other faults with the same symptoms?

[DiscoJeffster]

That is a reasonable diagnosis HOWEVER, if it’s not, you’re probably up for a new Ford Territory replacement engine.

Yeah I don't really want to go down that road on a 3k disco if I could be sure it's a common issue I'd jump at it and fix it

Sounds like MJRs $5k Disco project ha ha

How high mileage?

That’s the logical theory but we are all dying to know if it works for you.

While you are doing that job you’d be blanking egrs and replacing the coolant junction on top of motor.

It's got 300 ish on the clock I'm going to have a look after work tomorrow and yeah blocking egr and replacing all the hoses will be a must now it's been contaminated owner says its recently had a radiator and cross over pipe replaced vac pump inter cooler hoses lower arms ect all the usual stuff. It could be a bargain or a disaster

[DiscoJeffster]

Haha. I only just clicked on the overlapping threads of new D4 and old D3.

Good luck with it. Keep us informed.

Yep some proof this is is a source of contamination is of great interest.

Tread with caution, Most owners would have diagnosed the car and know exactly what it needs and are trying to cut their losses.
I doubt it will be an "easy fix' - but if you're up to the challange and can do the labour yourself, you can still save a packet.

Do keep us informed!

My D3 has recently shown up some trace indications of coolant in my last handful of oil samples. Just currently shy of 330,000km on the donk. I've read a little around the traps about oil cooler failures, which seem to show up as oil in the coolant so I think Im looking at the beginnings of a likely head gasket issue.

Na or trace glycol showing up Shane?

Oil cooler and head gaskets are two completely different issues.

[shanegtr]

Glycol is not testing in my samples, however showing Na and K. Gone from typical 2-3 on Na to 7-8 and 1 or less on K to between 5-11

Agree, but both could cause a cross contamination of coolant/oil. Just which way around the contamination goes could vary depending on the actual issue

Hows the Si?

Elevated K with Si can be dirt, too.

Had a spike two samples earlier, but settled down after that.

Ok so I got to work on reg the disco one of the previous owners kids called it reg and it's stuck soon as I got it home I dumped the coolant to prevent further damage to the hoses and was pleasantly surprised to find it was 99% coolant and looked a lot worse than it was

Getting the cooler out is a fair old challenge to the patience couple of things who ever thought split tube over the wireing and who came up with the oil seperator needs a serious flogging.

trying to keep the brittle tubing out of the filter housing was a serious task I ended up using a vacuum cleaner to suck it all out .

A couple of low pressure quick release fittings broke too but a trip to the wreckers sorted those and the elbow on the hose that attaches with the wire clip snapped as soon as I touched it so now need a complete hose to replace it. I actually bodged it up well enough to hold water to flush the system.

Yep I noticed on my last job that those split tubes are brittle and crumble when touched. The vacuum is a good tip before and during.

Also a good rubber glove peeled over the top of the filter housing when I vacced I went round all the crumbly split tube and and crushed it in my fingers next to the nozzle I need to get back in and tape up the loom or re split tube it I think with the engine cover left off it won't be a problem again as the heat won't be trapped

Would not be hard to replace at same time with new tube is my thought

Looking at the engine pic I clearly see the issue. Your engine is upside down!!! [tonguewink][tonguewink]

Yeah it works better in the Southern Hemisphere. Got it out in the bush this weekend on a trip to my mates bush block went faultlessly did a little sand driving along the river and performed much better than expected
