Hi all,

I have a technical question (or two) = pulled the oil stick on the Daimler V8 the other day, and oil level was above max Rolling Eyes Sad

Then I removed the radiator cap, and saw the water level was only 2 third up in the radiator Rolling Eyes Crying or Very sad
Tonight I then wanted to see if my suspicion was right, so I removed the drain plug, and sure enough, some water came out first Rolling Eyes Crying or Very sad
but only a small amount = less than half a cup (if that much ?) then immediately followed by Black oil. I didnt know if its a combustion chamber that have leaked or what ? but the engine turns freely = gave it a few full turns.

My question(s) are as follows = could there be water in the oilfilter ? cant see how it should get there ? then there is a matter of checking the engine, to see if I still can use it ?
I am thinking of draining the rest of the water, pour some oil into her, and then start her, and while she is running start pouring fresh water mixed with cylender block sealer into the radiator - how do that sound ?
Something like this = http://gobdp.com/blog/repairing-cracked-engine-block/

My other idea, was to use a Webasto engine heater, on the cooling system, pour the water & sealer in, and leave it running for half an hour, without starting the engine.
That way I dont risk ruining new oil, as I will not fit the oil drain plug , this way I can see if the water leak stop, before I fit the plug.

Any thoughts or better ideas are welcome Smile

Ohh and before you start commenting = here is the story on the engine.

I found it in a very sad state Crying or Very sad the alloy between all spark plug holes in the heads, were cracked (big chunks of alloy separated from the heads)
The block was cracked on the middle half way up, and all frost plugs were pushed out.
I had the heads & pieces welded back together, and the block was also welded up.
The engine was not 100% sealed first time, so I used some engine sealer for the radiator system, and it worked Cool used her for more than 10 years, without any problems at all.

Hi Jens, If you have recovered it from that level of disaster and it has been trouble free for 10 years and the quantity of water is very small I suspect that a weld somewhere has become porous or your previous sealer has given up. I would change the oil and try more radiator sealer before attempting anything more fundamental. Here's to the next 10 years!!

Hello Jens, exactly as Paul said, new oil fresh water new sealant. Even if it costs you two oil changes and two filters you are way ahead!
Good work resuscitating and using the engine for so long against such odds!

Hi guys Smile

Thanks for your nice compliments, and advice Cool

Someone suggested that the water might come from condensation, but I really dont think so (given the history of it)

I used Holts engine sealer last time, and it worked really nice.

Back then there was no chemical metal, that would have been handy.


I did buy a spare engine last summer

but that will also take a lot of work to get going, and I am one of them types that dont like to throw away things, especially if they can be repaired.

Drain the oil. If possible remove the sump. Fill radiator with water, then pressure test the radiator/cooling system, borrow or buy one of these:

Thanks, but I know where its leaking, so that wont be an option, I want to see if I can seal it again, before I do any more work.
If it wont seal, ill just put in the original B18B engine I have for her.

has anyone any idea which is the best rad/cylinder head seal? My Lanchester 14 is losing water, where from I don't know. No steamy exhausts anyway.

I've cured minor leaks in the past with K-Seal, much better than Radweld IMO. Last time I used the latter it gummed up my heater tap, so I've not touched it since. I have however used K-Seal on a couple of occasions with success. Although if the leak is serious, it would warrant a deeper investigation.

I've found Redex Soldrit to be good, but sadly I think it's no longer available—I'd be happy to be proved wrong on that point.

These heads were always prone to corrosion, I would guess some of the old welding has failed. K seal is supposed to be the best sealer, but it wont stop a radiator leaking with a 15 lb. cap

The Goo you see in the picture is all from above the sparkplugs (in the holes they sit in) not inside.

Bores & pistons are all clean & dry.

Engine spins nice too.

I will connect my Webasto car heater to the cooling system, and run it a few times, while I watch for water at the oil plug hole, and in the cylenders.

Hope to do the test this week.

Jens,

Can you get hold of a radiator pressure tester? Pump it up to whatever your cap pressure is and leave it a while and monitor the oil drain for water. If you do get water in a cylinder it will hydraulic lock and won’t turn over.

Is the oil down the spark plug tubes because the tube seal have failed/hardened?
