Hello, I am trying to figure out the specs for a 5.3’s cylinder bores,
i need the range of acceptable sizes. I can’t seem to find it in the shop manual, it just states that it should be 3.543 but no + or - specifications are given.
Thanks.
That gets into the A and B spec liners. You’re not supposed to care what the tolerances are, if there’s anything wrong with the bores you’re just supposed to replace the liners.
Okay good to know, so if its out of spec (3.543) at all then you just replace them? That makes it easy then, is there a specific way to replace them? I’ve never dealt with a sleeved engine before.
Yep. Just go down to your neighborhood Jaguar dealer with a wheelbarrow full of money.
Seriously, those liners are probably difficult to find any more. If yours need work, you might consider Lutz’s plan of boring them a bit and installing Chevy 305 pistons.

If i am not mistaken SNG Barrett and Terry’sJag sell them. but it seems that they are only available for the Pre H.E. engines. do the liners generally wear all that much? or are they pretty stout?
I don’t think they’re different! The pistons are different for sure, and I think the liners for the 6.0 are different, but I don’t think there’s any difference between the pre-H.E. and H.E. liners. I’m sure someone will correct me if this is wrong.

Well, that would be cool! for reference these are the ones i am talking about. I would be very interested to know for sure if they are the same.

SNG: https://www.sngbarratt.com/us/#!/English/parts/4bf51fbf-4128-41c8-a8ac-f7547ad71fae
They look the same! It’d be good if somebody compared part numbers.
I didn’t see any mention of A vs. B on that listing. If you’re reusing pistons – which I suppose is unlikely - you’d want to match the piston. If you’re using new pistons, you’d want to match the piston.
I wouldn’t recommend any more than 92mm bore using std. liners. Chev 305 pistons are 95mm and require larger liners.
Well if I get a chance I will buy one of these sleeves and compare it with the OE H.E. sleeve and report back. but that may be quite a while.

Don’t waste your money, 5.3 and 6.0 liners are the same, there is only a 8.5mm increase in stroke.
Even for my 7.5L. with 90mm. stroke the liner used is the same as I use for the std. 70mm. stroke crank.

If custom sizes are needed there are a fair number of built-to-order cylinder liner places out there. I don’t know how prices compare to off-the-shelf units but among them are:

Mahle has apparently made them too - but I can’t find a catalog reference… maybe a phone call would work?
I’m sure there are more.
I know Rob Beere supplies a set of 96mm liners for about 1000 UK pounds. I think anything over a standard liner bored to 92mm requires the block be worked to allow for a bigger liner.
As noted the 6.0 and 5.3L HE sleeves should be the same. I wouldn’t be surprised if the pre-HE sleeve is the same, but it’s not being listed as such: e.g.: https://www.scparts.co.uk/sc_en/cylinder-27115.html
Pistons for the 5.3L HE are NLA so I understand, but at the point where you’re replacing internal stuff like that usually an OK used set can be sourced, OR, once enlarging, it becomes far easier just to either have custom pistons made, or bake your own combo, or use recipes already available --> Normal Lutz, etc.
For very large displacement changes (getting into the high 6.x / 7 liter range) - any that require a block spacer - Donald Miles supplies a head spacer with sleeve spacers that go at the bottom of the sleeve bringing them upwards, and preventing the bottom of the sleeves from having to be modified to clear rod throws.

Cylinder liners are all the same with a small difference that makes no difference… The 6.0L liner is about 3mm shorter making more clearance for the crank.
For those with a 5.3L engine the compression hight is (at least on the Pre-HE but not on the 6.0L) 39.7mm. You can get off the shelf from Mahle a 92mm Volvo piston with a 24mm wrist pin and the same compression height. Jaguar wrist pin is 23,8 and enough material in the small end busch it to enlarge it to 24mm.
The Volvo piston comes in different shapes (dish) depending on turbo or non turbo…
Have fun 
Do you know the compression height of the HE 5.3 engines?
Robert, i can supply a 95mm Liner that uses KB 305 Chev pistons that you can source locally.
A set of liners cost US$ 750.

My 7.5L engine is done using my standard 95mm Liner, without a head spacer .
What most people don’t realise is that the V12 block is the same deck height as the 350 Chev (9.027"). So allowing the use of a lot of Chev parts.
For a pre HE 7.5L I use the Chev 5.7" rod, and for the HE 7.5L, either the 5.7 or a 6.0" rod, both with a 305 Chev style piston.

Thanks Norman! That fills in a blank spot for me - the deck height.
Now that I look through the pictures I have and pictures online, it seems the piston I have in hand is a 6.0L piston which has a compression height of about 37.9mm also ( measured by plastic caliper…) Looks like about a 1.5mm dish in it.
*edit out - nope… had my math wrong here * ignore… wrong stroke used.
That gives a 4mm + gasket quench distance on the std 6.0L.
< end edit>
So… math… 6.0L:
(1/2 stroke + rod length + compression height) < Deck Height w. gasket.
(78.5mm x 0.5) + 151.4mm rod + 37.9mm comp height = 228.55mm
So the gasket has to be 0.264+ mm with those numbers.
(I have a spare of the piston on the left.)
Doesn’t the block need to be bored a bit to allow the 95mm liners to fit? If so what do you think the avg machine cost is on that?

Paul, I don’t know what your shop rates are, but if you work on $100 per bore, you won’t be far wrong.
