    Heads or not?

    Got a coolant leak on the passenger side engine rear of my Discovery 2 V8 2002. Photos show leak from above and below. Heads are stamped C. Ignore the valley pan oil leak.

    Could this be anything other than a head gasket? Do I need testing to confirm or is this proof enough?

    All these confirm is you have a leak somewhere,, the second pic is just a drip, the first looks more like spray, those small pink bubbles will be just spray on oil.
    any excuse to get rid of the pink coolant though. Just Do It.

    I used to hve this problem with my 3.9 even with new heads.

    I was told that the Elring gaskets (OE) were good for compression but bad for leaks.

    My theory is that the blocks relax over time and are actually a bit bowed so the coolant leaks out of the ends.

    It is not a big deal as the coolant passages are right at the end , and it does not imply that there are compression leaks.
    If you are a perfectionist like me , you will probably replace the head gaskets but now I am older I would probably just live with it as you only usually lose a small amount of coolant.

    I noticed the same thing on my 2004 D2a when I first got it and ignored it, 20,000K's later it cost me over $5K to get the engine fixed (including new head gaskets), Nip it in the bud early is my advice

    I would remove the spark plugs. Check for the smallest amount of moisture in any of the cylinders. If non, all good. Should be a gasket issue which in all fairness is easy to replace.

    If there is moisture in any cylinder I would be concerned. The level of concern would also very. If water is in any cylinders near the firewall or radiator I would be less concerned than the other four.

    (I had a disco with a dodgy lower block. In hindsight it was a very disappointing way to end my relationship with the disco. A combination of LR fingers crossed and crap manufacture).

    The motor looks to pretty clean. I hope it wasn't a recent purchase.

    There are some people with low morals out there with respect to offloading cars with terminal issues.

    The D2 I think are a complete risk to own and honestly you have to have rocks in the head to be buying one.

    Look it is very unlikely that this is any more than a leaking head gasket.
    slipped sleeves etc do not show external leaks, as the water goes out of the exhaust, and they generally only affect the centre 2 cylinders.

    V8 heads generally do not crack either in my experience.

    If you want to gain some experience you can replace the gaskets yourself .

    regards Philip A

    Thanks all

    Thanks for the replies everyone. I'll be skipping the leak down testing and taking the engine apart this weekend to replace the head gaskets. Good to know it doesn't look like more than leaks. Spark plugs and cylinders looked dry when I replaced the plugs and leads 200 km ago.

    The motor isn't that clean, just been degreasing it to find the oil leak. The leaks aren't terminal, no overheating yet, and most vehicles, discos or not, will need an engine refresh when they've done 200000 km.

    Will be nice when it doesn't smell like syrup, as my kids say. Been a few requests for pancakes this week.
