Hi!!!!
I got a 98 Dicovery with the 4.0 V8----I am starting to develop a slight "Knock" from the upper end of the engine on the drivers side----oil changes have been done religiously at 3500 miles with castrol GTX oil----Has anybody come across this before??? Are the rocker arms/pushrods adjustable, as this could cause it, but I dunno

Anybody, is it normal for a slight sound on initial start with engine of something like a pinging or valve clatter, the noise goes away when the RPM reaches about 1000, then the noise dissapears. Any help would be appreciated. Thanks.

Oil pump failure by merediths

I have a 2003 Disco and the oil pump went out on me. 1400 to repair and they aren't sure if it has done any engine damage. They are saying at least $10,000 if the engine went out. Only 57,000miles. I am so scared right now. Any suggestions on what to do if the worst case scenario comes true. It has been in EXCELLENT condition until this. Does anybody have any suggestions? Thanks. Poor Texas Girl!

I have a situation very similar to yours. 03 Disco, just had its 60k service ($1000) in Dec 06 now last Friday the oil pump failed. I tried to work with the Land Rover North America customer reps, no resolution. I went to the NHTSA and submitted a complaint, this is the start of a potential recall process. I recommend you do the same and if you hear of anyone with the same issue have them do it also. That is the forum to get resolution. I have had two Land Rovers, now both have had significant service problems that Land Rover wouldn't help with. They were right owning one is an adventure, good luck.

Land Rover 2003 Discovery Oil Pump Failure by pummell

Land Rover owners and potential owners beware. I just had my $1000 60,000 mile service a month later the oil pump failed. It cost $1700 to fix. I tried to work with Land Rover at the corporate level and no help. Their opinion is that it is my responsibility.
 
Be very very careful before purchasing a Land Rover. I have now owned 2 and both have had significant flaws one led to a coolant recall and I am now working the oil pump issue. I think it is time to shop for a Jeep or Toyota.

hey guys,
   2003 discovery 4 days after warranty expired, the oil light went on and the engine blew. 44K miles. Land Rover told me tough luck. There is a Tech Alert they issued for the 03 and 04 discoverys regarding a defect in the oil pump. I'm fighting them. If you have the same problem or hav had it, contact me and I'll give you the alert and who to talk to over at Land Rover. thanks

We have had the EXACT same problem, down to the mileage. 44,274 miles (changing the oil every 3,000 miles)and the oil light went on and the engine blew. Our warranty ended 28 days before this happened. Land Rover of Milford said they'd pay for 1/2 the engine. We knew about the oil pump problem, however they said it would have blown by 20,000 miles of that was in fact the problem. Now I hear about you and the other person at 57,000 miles. Obviously there is a serious issue if all of these oil pumps are blowing out. I am going to file a complaint with the NHTSB like the other person, maybe if we all do something can get done. Keep me updated and I'll do likewise.

Did you have any luck? We had the exact same thing happen and thanks to your suggestion, just filed a complaint with the NHTSA. Let me know what LR did for you, if anything. This is our 2nd Discovery and our first problem in 10 years with them. They have always been great for us until now.

Hey guys, im new to this forum but wanted to put my two cents in as well. I purchaced my Disco '03 in July of '06 with 34,000 miles on it. About a week ago (at 44,000 miles) the oil light came on and I noticed heavy leaking from the hoses on bottom. Anyways, I took it in and yes, it was the oil pump for me as well. They said the gear broke in 3 places. I believe that since I have the extended warranty they it will be covered, but what really got me upset was the fact that they were going to charge me $360 for the disassemble to get to the pump to find out the problem.
 
I dont know how severe the damage is. I am assuming that it isnt that bad since i cought it in time and there was no knocking or wraping. But this should be something that '03 Disco Owners should be aware of and Land Rover should make a more Pro-active attempt to let the owners know, since they do have the Vin numbers of what cars could be affected by this.
