It looks like the first listing has had the engine lifted and twisted which is never ideal.

I'd prefer to go with what I know and have my engine rebuilt. I've been ripped off with recycled parts off low mileage cars that come with an incredible amount of bearing play. If your own engine block is rebuilt you can then decide how far to take it. If you intend keeping it for a few years then I'd look at renewing the oil cooler, turbos and EGR at the same time. Then you should have your few years into the future trouble free and the cost can be amortised over a ppm or £/year to become a sensible figure.

So finally got around to looking at my poorly engine. Decided to pull it and see what damage has been done, hopefully as it was still running and the knock sounded like a big end as opposed to a main bearing it maybe salvageable.

Me and a good freind spent 5 hours over Sunday pulling the front end off, working on it outside on the drive as we decided the garage is needed for removed parts and maybe the engine stripdown.

So, 5 hours in and this is where we got to: -




Awful lot of pipe work, even once the Radpack is out of the way.





Had another couple of hours on it yesterday and here it is!




Left a big wide empty engine bay to stare at!





At this point we decided on pulling all ancillaries to amke it a bit easier to work with, it's a heavy old thing.




As we were doing quite well and no disasters, I couldn't wait any longer to get the sump off to see waht had failed, so here it is!

On removing cylinder 3 big end cap you could clearly see that the shell had spun about 10 degrees, obviously enough to restrict the oil supply. The lower shell had more wear than the upper and had picked up on the crank journal.

Plan is to get the bottom end over into a mates workshop as he has a parts hot washer and machining facilites. Gonna pull the crank and go for a regrind, quickly checking I see that King Bearings go upto 25 thou o/s, so should be plenty of meat to work with. Obviously a good degrease and a few hours in the parts washer to make sure it's all clean.

Only thing I'm not sure about at the moment, is whether I pull the heads off or not as the workshop manual states they are not machineable and there are only standard gasket sizes available. Max deviation measured diagonally is .2mm, so If I pull them and they exceed this figure, I'm then in for a couple of heads - going to weigh up the pros and cons, once it's a bit more stripped.

Any comments, tips or suggestions would be very welcome!

All the best

For the reason that Craig mentioned earlier, I’d strip and clean it and put it back together to have peace of mind of no bits of metal lying about.

But it’d be a case of remove and refit with new gaskets etc. if it’s not showing any signs of being of line then I’d be happy to work on that basis. V8 or else ...

If I get a bit of time tomorrow, I'm going to pull the crank out, inlet manifolds, cams & followers etc. and give it a good wash through in the cleaner and see what it looks like. Ultimately if I need to take the heads off to be happy that's what I'll do.

My mates workshop in Telford where I'm going to take the block to faces cylinder heads for a living and says he's very sceptical of pulling the heads without any warpage. He's saying that if we do and they are warped he can face it and drop the valve seats etc. to allow for a standard gasket (as no thicker items are available).

All other parts can go in the hot wash, obviously new genuine LR pump & re-worked turbos for the rebuild.

Got a local guy who does a lot of crank grinding for Matt Lewis Motorsport and he's happy we can grind the crank & go with oversize shells, which are available upto 50 thou o/s.

You might want to see if bearing sets are available with 1 side notched to then have the caps notched. I understand they're available for the TDV6.

That's a good idea, the ones I've managed to find so far are however as per standard design. I'll keep looking Thumbs Up L405 SV Autobiography LWB SDV8, finished in Aston Martin China Grey by ETO division.

So, it's been a while.... some good and some bad news!

Turned out the crank was 4 thou outside of tolerance to grind and therefore I had the dilema of whether to source a secondhand genuine crank or go with an aftermarket item. Speaking to a few people the consensus was the Chinese cranks (Apex and the likes) are to be avoided as they have been known to have balancing issues. The Turkish manufactured cranks (Rotweiss) are much better, but still not OEM by a long way.

So mind made up, I managed to source a secondhand shortblock (block, crank, rods & pistons). The crank was perfect and measured up as Std size so it had never been ground. The block was much better than mine wear-wise so decided to use the donor block. I went for my good 7 rods and used one from the donor short block as I didn't want to use my No.3 rod as this is the one that spun the bearing and whilst it measured ok with a bore gauge for ovality, I didn't want to risk it, even though there were no signs of over heating.

Took the block & crank to Hayden at Gee Engineering (top man) and his opinion was even though the bores had minimal wear, which he could hone, he would reccomend boring to first oversize and he could source oversize OEM pistons. In for a penny and all that, so that's where I ended up!

Got the short block back last Monday (half term skiing got in the way) and started the build. Put everything through Dave's (Head Technique, Telford) hot wash and the heads through the acid bath, first (lots of carbon build up in the inlet tracts) Dave then skimmed 4 thou off the heads (and sunk the valves by the same amount) to ensure a mirror finish, ready for the new gaskets.

Here we go at last!

Brought the engine home on Friday after work and continued for a few hours today (Saturday), added genuine LR timing chains, tensioners and guides and timed it up. Could not get any of the other required special tools aftermarket so had to invest in the LH bank sprocket locking tool (JLR-310-247).

Click image to enlarge


Timed up the HP fuel pump ready for assembly with tool JLR-310-248, apparently a lot of people don't bother timing it but as it is a 2 port pump (similar scenario to the SDV6 pump) it should be timed to make sure the correct bank is on pressure, otherwise it can lead to rough idle and poor mpg.

That's it for today, other duties to complete for SWMBO, hopefully I'll then be free all day tomorrow to finish the build.

Any comments or advice, please feel free to chip in! L405 SV Autobiography LWB SDV8, finished in Aston Martin China Grey by ETO division.

Have you considered fitting a sensor for an oil pressure gauge whilst easily fitted, even if you wouldn't normally have a gauge fitted?
I fitted one the my L322's 4.4 TDV8, installing a T in place of the switch which was then mounted on a 90 deg fitting to ensure that the switch didn't interfere with anything else. In the picture the switch is foremost with the pressure sensor behind. The pressure sensor is 0-150 psi in a kit with a 0-100 psi gauge. 0-100 psi sensors are available and would be more accurate but I couldn't find one in a kit with a gauge.
