A Good day to all,
I will try and keep this short.
I have had small end bearing damage in one conrod and I have noticed prior to this ring wear on stripping engine down, so I am changing all the rings and bearings whilst the engines dismantled. It's the first time I have done this work.
The main issue I need help/info with is:- ''I have a problem with sourcing rings. I checked on various sales catalogues and basically for what i believed was my vehicle I.D over the years was as above and an FXFA code on vin searches too and other parts ordered.
All or most searches come back as ring size Ring 1, 2.50 mm Ring 2, 2.00 and ring 3 and 3.00mm. Like an idiot but due to everything else going on I spent some time and ordered a set of rings at those specs, yet took it as fact.
When they arrived I started to clean pistons and remove old rings and noticed they were all 2.00mm.

If I try and find 2.00mm rings the closest I get is for a JFXA code and others, but all are in a very different engine group from the F4FA 75ps, D2FA,D2FB,HEFA 90ps, ''FXFA 115ps'', D4FA, DFFA 120ps, DOFA 125ps and the H9FA 135ps group.

Mine has always come up as TDE too and mainly MK6 TDE but sometimes MK5 TDE with years from 200 t0 2006 but often 2004-2006.

I can find many for the 2mm for the bore size of 89.9 and would be happy fitting these if bores just need a hone after taking checking ring end gaps in situ, which I hope will be fine as there is still much crosshatching inside the bores. Currently at 165,000 miles.

I would appreciate anyone's experience and or knowledge on this. I will check regularly to respond to replies.

There's questions I need to ask, but I will save them for the none technical area's of the forum.

I hope I have the correct section.

Thank you.

May I add,
one of the things i can think off is someone has put in a different bottom end or my engine was a one off line and or someone has put an old type cylinder block on top of the post 2006 TDCI engine. which only seems to point to a different group, but would that not match? Or someone before me has put in the right size pistons with the thinner 2.0mm rings?
The ring sets I can only find for 2.0mm too come up as 115ps 85 kw but are for tdci up to 2014? Maybe, but there abouts.
carcar.info comes up with 2.00mm under part number1369688 (class A)? for a full piston and ring set once I search for that number elsewhere and check the ring specs. I come up with Ring 1, R 2 Crk. Ring 2 NM 2 P. Ring 3 DSF 2 N. Which is what I am inclined to go for, minus pistons. It's the only place I can find rings to fit these pistons, everywhere else states different spec rings. 2.5mm 2mm and oil ring 3mm.

Its a conundrum don't want to order wrong size or metal type for piston again.
Any help re the above would be appreciated.
I have had this my van for 7 years and done a lot of work on it and want to keep it on the road and get things right.
Thank you.

Cant offer you any help on the rings, other than order through ford dealer, then you are bound ton get the right ones, but will point this out as regards small end failing . there are oil jets that squirt oil into the bore and under the pistons make sure they are all clear ..as it is likely that one of those failed and is why the small end failed.

Thank You That sounds like very good advice. I am wondering why it failed and trying to work it out. I will get some cleaner into the oil ports and then compressed air. I don't want it happening again. All the tolerances, clearances so far for the other pistons seem fine. I changed the oil and filters regularly but on inspection inside the rocker block and sump, I may of been a little over enthusiastic, rushed with the sealant after a timing gear change etc. Oil pressure down was another thought, but that was fine and would of effected more, I guess.
I did have the timing go out on me twice and that piston was scored by the valve heads, but i am not sure that was the main issue as the small end bearing looked as if it had fused due to lack of lubrication as you have suggested.
Thank you

For some reason I never thought of asking Ford main dealer. Perhaps I will give them a ring tomorrow and reply back here afterwards.

Someone may have re-built the engine before with aftermarket pistons/rings..?? Hence the different rings & pistons.

Mk6 engine is vastly different to the Mk5. All Mk6 2.4 engine blocks are essentially the same.

It's the only thing I can really think of myself. The engine was in a very oily mess when I went for it, but was running fine. I realised after two attempts at a rather high learning curve about timing and getting the right timing gear, tensioner. Lol That that may of been the reason and now looks like it was rebuilt too, as your good self suggests. I'm happy to go with that. Thing is the chassis and underneath was in such good condition due to it being covered in oil for what must of been a long time, there was virtually no rust. ''WAS'' Lol but I am still on it, given where I now live, on a valley side in a forest, drizzle and mist, just over the last two years have started to do it's best.
I'll do a good check tomorrow on the block and cylinder and write down the codes, numbers and see where I go from there.
Thank you Lord Knobrot ''Knobby1'' I find your reliable when it comes to reading your comments on such things.
