Thread: This is not how my D2 V8 should sound!

Sounds like liner moving in block..do a search on rover V8 liners moving..unfortunately a common fault especially if the engine has been overheated at some point, sorry to be the bad news person.
They can be fixed with a new set of liners(top hat) and bored out to suit pistons, however if it were me I would get new pistons and make it a 4.6.
I have had 2 3.5V8's converted to 3.9 using new liners and bored out, but you need someone who knows what they are doing with the Rover V8.

Awesome thanks Brad, no such thing as bad news, just another challenge to overcome really.

When arriving there tonight, I spoke to the senior mechanic, who actually mentioned that this may be the case and that tomorrow he and another mechanic from Land Rover with whom he worked will be taking a look into these items. He did not mention that it may have been due to an overheated engine! Does this mean it more than likely has been overheated, or could it be down to mileage and something else, the engine has 226000 kms on it.

I will be going past in the afternoon again to take a look and see what they have concluded.

In the interim, the call on the oil pump was a good one, it actually has a crack in the outer ring, I will post a pic (The mechanic was good enough to give me the spares as a souvenir), I inserted a toothpic between the crack to open it up for people to see. My real concern now is, has any thing else being damaged due to this been faulty and not getting enough oil around the engine. Especially to bearings and shafts. And how does an item like this crack, it is not like it is a piece of sheet metal. Basically what items should I be paying special attention to now?

When you say it can be fixed with a new set of liners(top hat) and bored out to suit pistons, what all does this entail?

Re bore to 4.6? Hmmm, sounds like a plan.... but the cost of petrol this side is killing us at the moment, not to mention this would probably mean an entire strip and rebuild engine wise correct.

Thanks again for your feedback, one of the main reasons I wanted an LR is because of the great people who own them.

Will post the next update tomorrow.

The bore for a 4.0 & a 4.6 is identical. To achieve a 4.6 will require a new 4.6 crankshaft and connecting rods, not an overbore.
If the engine has suffered from overheating & oil starvation there are likely to be other related problems, camshaft, lifters, followers and the possibility that the block has softened.
Looking on the bright side, you may end up with a reconditioned engine at no cost, apart from inconvenience, under warranty.
Best of luck.

How many km's did you do with the new lifters,why i ask this is you really shouldn't fit new lifters to an old cam as the cam will wear the lifters out prematurely.

Thank you for the replies. I don't think the dealer will grant me the wish of the 4.6 and parts, so I may have to end up paying for that luxury. But it is good to know what will be required. The vehicle has not even been driven since the new lifters were inserted, because the noise remains, and I am not taking it back until it is all sorted.

After looking over the web last night, the more I am beginning to think it may be sleeves. These are some of the clues I picked up.

- The noise is only there when the engine warms up.
- The noise does dissipate when revving the engine a little.
- On idle, the noise is there, and then sometimes goes away, and sometimes not but decreases somewhat.
- After these small part changes the noise is quieter, but still there.

Based on the outcome of my meeting with them this afternoon, do you think it may be a good idea to start hinting on a reconditioned engine, to save time and cost on their behalf.

basically,yes,But they may try to get you a used engine
this site will give you an idea of costs.

It wouldn't be a plug pinging would it?

What does a pinging plug sound like Swarvey.... I am going there just now to check on progress. However, after a very lengthy discussion on Friday, it has been narrowed down to the left hand side (passenger side) and is toward the rear of the engine and could possibly be a valve seat that is loose. I am just waiting to get another opinion from some other "engineer" today and then we will know the way forward.

If this is the case, reconditioned heads will be inserted and then lets hold thumbs. It is a frustrating lengthy process, they seem to want to go item by item, so I may end up with a reconditioned engine at the end if it does end up being a dropped liner.... well so they say.

But I will keep you posted on more progress tonight.
