My ZR died, was fixed, but is now dying again. Details of events below. Any ideas would be much appreciated. (This car is the bain of my life!)

It had been playing up for a couple of weeks - the engine occasionally started to shake when driving along like it was running out of diesel say (when it wasn't). This happened a few times over the couple of weeks and then it finally died. Would not turn over at all. Completely dead.

Had my mechanic friend look at it and he eventually (after taking the whole engine apart) managed to find the cause (or so he thought). He found that one of the valve seats in the head cylinder had broken away - there were about 5/6 small little bits of metal from the seat that had been flying about the engine, clearly getting in the way of the pistons as they had small metal crushing marks on them.

Had the valve seat replaced at an engine specialist and didn't need to worry about the pistons (apparently). Friend put back together and got it going. Seemed lumpy at first because it hadn't been driven for about 4 weeks - he said that that was normal and it should start running normally again soon.

However, the next morning I started it and it was back to how it was before it finally died on me the first time. The symptoms include whole car/engine shaking when on tick over (coughing and spluttering) and only seems to disappear after I've revved gently and had it running for a while.

Because of the fact that my friend got it going from it being completely dead after he found the valve seat problem, do you think it's still something to do with this area or something completely different? He did mention something about the diesel fuel pump timing but that's no where near to obviously where he fixed the head cylinder/valve seat???

PLEASE HELP!

Many, many thanks if you reply with any suggestions.

To do any work on the valves, the head would have to have been removed, and the fuel pump timing belt removed as well.

L-series diesel fuel pump timing is absolutely critical, just a tiny smidge out and it'll bring the engine crawling to it's knees. Probably a good idea to take it to someone familiar with the engine and get the pump timing checked out. Anyone who works on early LR Freelander diesels should be able to help, as they share the same engine. :)

That's great, thanks. That makes so much sense too. I'll start looking around for anywhere familiar with ZR diesel engines and the fuel pump timing in particular.

Just one question - have you got a rough idea of how much it should/would cost for someone to fix the diesel fuel pump timing?

Many, many thanks again.

Shouldn't be much, as it's really not a particularly involved job, it just needs to be done absolutely right. :)

I certainly wouldn't want to be paying anywhere near £100 for someone to check and reset the pump timing, personally. Whereabouts in the country are you?

Might be worth posting over in the diesel section, as there may be someone local who could pop over and take a look for you!
