    Default 15P TD5 Block with 18P TD5 Components

    Hi all I am looking for some advice, the previous owner of my Defender had cracked the block of my 18P TD5 block. This was only discovered replacing the head gasket (The head has been pressure tested and is good to go). As there was no loss in compression, oil mixing with water nor any of the other usual signs it went by unnoticed.

    I currently have 2 options.

    1. As there were no tell tale signs of a cracked block I am sending it to the engineers to see if in their opinion it can be fixed (stitch welding etc), all depending on what the pressure test reveals to us. I am hoping it can be fixed as this would be my preferred option, depending of course as to what the engineers report. (I wont have bureaucratic issues with an engine swop if I go down this route)

    2. I have managed to source a second hand stripped 15P TD5 Block, this will need to be pressure tested, acid bathed, rebored and resleeved before I can continue. However once all that is done I am curious to see if there will be any unforeseen challenges in fitting all of the working 18P components to my 15P block?

    Are there any other options aside from a complete engine swop/overhaul that I could look into?

    I have attached a photo of the cracked block, which you can see is on either side of cylinder 3. As well as the 15P block I have managed to find.

    Cheers

    From the head up there's no problem,the 19p head and bits all fit. The 19p piston rings differ from 15p, this should not make a difference as long as you get the correct new rings to match your pistons, they will still fit the 15p block, other than that I don't recall there being any issues. Make sure you use a decent engineering shop, I would hand over all the bits to lrxtreme and let them do the entire job.

    I would rather use the 15p block than try fix the 19p block, it's another "fix" to worry about later on..

    Give Landyluver on the forum a call, he will know for sure.

    If you need any 15p bits to match your block let me know, I have some spare..

    I am all for supporting good service providers, and i know walter runs a tight ship, but do they actually do rebuilds? I was under the impression they outsourced this, like the gearboxes.... so would one not be better off going direct to engineers. In pretoria there is probably no one better than the guys at allen y brink.

    They do outsource the engineering so the engineering shop has probably done many, but they assemble themselves and it all comes with a decent warranty and you get a well done end-to-end job.

    IMO starting from 15P all of them up to 22P(or so) are completely the same so all the parts amongst these shoud be interchangeable
