L series diesel,Mayo in the coolant

I have lots of mayo in the coolant expansion tank. I have searched the forum already and 1.8 petrols apart have only found reference to this problem on TD4s with blown oil coolers. Has anyone had this prob with the L series. Is it likely to be the oil cooler rather than the head gasket.

Probably head gasket they are notorious for it. Your best bet would be to do a prussure test.

The diesels aren't the petrols are

Well, the 1.8 petrol is. The V6 is much more reliable, all you have to do is look after it properly!

I'd be happy to argue that point.
From a head-gasket point of view the V6 is much more reliable than the 1.8.
Even my L series blew a head gasket at around 150k miles, but my V6 didn't despite having no coolant at one point.
We never hear about dropping cylinder liners on a V6, do we?

Or have you got any evidence to the contrary?

The V6 was Rovers most reliable petrol engine once the initial bugs had been ironed out.
The V6 suffers less HG problems because of the more conventional head bolt design. On the V6 the head bolts only bolt the head on. On the K4 the head bolts are much longer as they bolt the whole engine together in a sandwich between the bearing caps and the head. These long bolts suffer expansion and contraction every time the engine heats up and cools down again. This constant movement over time relaxes clamping loads. This and lots of other factors limit HG life.
The KV6 doesn't suffer from these K4 peculiarities.
The KV6 does pop HGs on occasion but mostly because of coolant leakage from the thermostat O rings. The lightweight design will not tolerate low coolant.
I've been running the K4 and KV6 for many years myself and worked on loads more in that time. The KV6 is much more reliable than the K4.

Sorry but t series was far more reliable

Link out the oil cooler, drain and refill coolant and run it for a while to see if the problem reappears.
Oil coolers can fail, oil in the coolant without coolant in the oil is a common sign.

Only if you carry a gallon of oil in the boot to ready to refill the sump every time you fill the tank with fuel.
And then there was timing belt failures that were pretty common. Or the sticking exhaust valves that were very persistent on some heads.
All engines suffer quirks. Some are worse than others but that adds to the character of them

Sorry your talking crap I worked at an independent land rover and rover specialist and although the head gasket oil ways did leak at 100 k they were neither unreliable or short lived.

Further to this the v6 engine suffers liner problems etc and ****ting itself .

I think your suffering I own one so it is the best syndrome and least we not forget recently the wrong advice you made on k series cam timing.

The 1.1 in rover 100 or metro if you like was okay, the 1.4 was reasonable and there on to 1.8 wasn't reliable. Now you can argue all you like but I know my local machine shop owner since I was 15 and he has similar views.

Maybe you could offer the OP some advice rather than putting down other's that do? After all you must have a wealth of experience in Rover products working for an independent!!
You obviously know more than me, so I'll leave you to answer all queries from now on, I just can't be arsed any more

The AA guy who I saw a few days ago said the V6 is a good motor, just don't buy a 1.8 whatever you do.
Mind you he was driving a Disco 4 so maybe he knows nothing also...

When you give wrong advice on k series 1.8 to make error is human, but your a zealot with regards kv6 and it really isn't that reliable with liner issues and plastic components failing.

Now if your giving good reliable reasoned advice that is one thing, but if your not sure it is better to check what your saying is correct or word it as a question rather than a statement.
