I'm having compression issues with my year 2000 TD5 and I wonder if anyone has any info on piston rings. My pistons are standard and probably original but after fitting new rings I'm finding a loss of compression. After a lot of head scratching (and eliminating everything else it could be) I did...

Update: with the MAF unplugged it doesn’t surge. With it plugged in, it does. It’s a new genuine MAF sensor.

It’s more noticeable when stationary and holding the throttle but I do get the sensation when driving it that there’s a very slight (you wouldn’t notice it if you weren’t looking for it) surge in power now and then. I just assumed it was normal. But stationary, it’s very noticeable and instant...

My TD5 seems to be randomly altering it's revs by about 100 rpm. If I set it at 2000rpm and wait; now and then it will bump up to 2100 for a few seconds and then drop again. It's instant and very obvious both up and down. Has anyone seen this before?

It dances a bit and there is visible mist chuffing out around it. However, when I took the breather pipe off and put my thumb on the pipe to see what kind of pressure there was it blew out the plastic cap at the front of head within about 5 seconds. That’s when I started to get that sinking...

I’ve just done a complete TD5 10p rebuild. The only thing I regret using was a Britpart head gasket. It is now breathing quite excessively. Whether it did from day one I don’t know as only noticed it by chance when checking the oil after 500 miles. It’s puzzling me. What have I missed?

Ok. Thanks for the advice 👍

Yeah I know what you mean. I’ll see if I can track one down. I’m sure no one will lie about it being ok🤣

I have no Cat or EGR so no problem there. I have noticed tonight that it is breathing far more than it should. Having done 500 miles since a full rebuild I’m starting to think that the problem may be more serious than I first thought! 🙄

Is that for a 15p or 10p? Mine is a 10p and I’m fairly sure (not 100%) that is a standard turbo. To be honest, I haven’t really looked into it because it all looks ok and like I said, no one has mentioned it. I know everyone is going to have a different opinion on these maps and it’s never a...

I didn’t remap it to gain more power and I didn’t know there was anything wrong with the engine. I just wanted to set it up properly. I’m not sure what ECU was in it. I was told but I can’t remember. I bought the truck as a project and put it straight in the garage and stripped it of all the...

No it was all over the place. The previous owner had all kinds of ideas, and not very good ones. Britpart crap was all over it giving massively out of range signals to the ECU (which turned out to be from a Discovery anyway). Genuine senders and sensors brought everything within tolerance and...

I'm looking for some advice on my 10p TD5. I'm led to believe that it's haunted by a mysterious LR entity and it's a lost cause! I have done a complete rebuild, which I'm told they just don't like for some weird reason. All parts and sensors were replaced (except the Britpart head gasket) with...
