Default 52 plate TD5 Sump filling with diesel

I have recently brought a discovery td5 on a 52 plate with 112,000 on the clock, upon purchasing i was told that the injector seals had been replaced. after owning car for 1 week only the sump again filled with diesel so I had the seals re done. the car was then parked up for 3 weeks and then used for approx. 180 miles and guess what the sump filled with diesel again. I have been told that this could possibly be a cracked head or does anyone know of anything else that cause this? Also with the sump filling with diesel would this have damaged the bottom end? I am unsure whether to find and mend the fault or try and sell the vehicle...

Afraid I cant help, I know nothing about TD5. It may make you feel better to hear that a friend has a brand new top spec Isuzu pick up, which is doing exactly the same. The oil level rises and oil is diluted wit diesel. Isuzu dealer are unsure what the problem is.

Had the same happen to me, it turned out to be a cracked head. Luckily mine didn't have any bottom end damage as it was discovered before it filled to much and wasn't used.

Likely hood is a cracked head, be careful the engine doesn't run off on you!

My first thoughts

Don't run it until the situation is resolved, I'm surprised it hasn't run away before now. By the time you get something to block the air intake it'll be too late and even more serious damage will be done. I agree the most likely problem to be a cracked head which will of course require skimming once it's repaired (if it can be repaired). Land Rover say that the TD5 head must not be skimmed, however it can be skimmed and I know of several instances where cracked heads have been repaired, skimmed and put back into use without any problems. Might of course be cheaper just to get a recon head.

How would the head crack if I may ask? What conditions would cause it to crack?

Had exact same symptoms as the OP on my 02 TD5 150k miles this summer.

With the injectors out, I could just see the crack by eye. I sent my head off to the chap who advertises on e bay... he welded it up and re machined it ..see photo below (injector #1 on rhs) (he also skimmed my exhaust manifold that had warped).

I put it all back together, new gaskets, seals, glow plugs, head bolts, new fluids and filters. And hey presto all fixed I've done more than 5k miles since, and the oil level hasn't moved, and shes as sweet as a nut.

IMO this was the best way forward, the alternative is to get a Turner head ()



I've found that you need to be very careful when checking the oil level, that the vehicle is on perfectly level ground, otherwise you will get a false reading.. possibly leading to a false diagnosis.

Ally welding is a skilled job as the whole piece needs to be pre heated otherwise the weld wont take. Ally sucks heat away from the weld too quickly otherwise. Having said that if its done properly the weld is as strong as the original casting.

How are you getting on with it now, did you find the crack??
