Engine Rebuild
After about 16 months away from cars to get head space I've split the failed B5234T5 engine down into its constituent parts.
So plan is to go for full rebuild. Looking for information if possible for the part numbers required for the following:
Also seeking unbroken timing belt backing plastic that the timing belt cover is bolted onto with the 12mm bolt. Part number 9135040 - specific to turbo B5234T units. Also on look out for an S60R exhaust manifold P/N: 30637921 Cheers.

waste of time, just get an RN 2.4 T5 and fit that.
your bores wont be parallel and probably have a settle groove up top, Mahle rings are hard to get hold of ( i do have a source that said ), and a rebore plus pistons is NOT cheap. Youll need oversize Wisecos or CP pistons as a result, a hone wont do it.

Timing had slipped so all exhaust valves bent back in Feb/March 2017 at ~30 mph so no over all damage to block etc. Ended up at the time buying a brand new ford focus ST line while i was considering my options. Mileage was not massive on engine - 143k approx. The strip down of the engine (it was always losing oil from seals) has resulted in good findings on the internals. No wear or striation marks on the piston sleeves. They are as polished as I presume they were the day they were fabricated for use. The mechanic I'm using specialises in engine builds and he seems more than happy with the condition of the internals - As above he was concerned about potential internal wear etc but said with spares he has stored from working on other engines etc that he can outfit a good engine once we source all the volvo parts (gaskets/bearings etc and piston rings) so as he has done good work for me before without issue I'm happy to go with his recommendation. I've had the misfortune of having bought 2 so-called "mint", "perfectly running" engines for said 855 AWD as considerable cost from breakers etc in UK and neither have lasted more than 8-14k miles despite having done stage zero rebuilds on each - either they burned oil or had internal knocking after a few thosand miles. So will never buy a £500 engine again with unknown history. Least with this engine i have undergoing a full rebuild I'll know it will be good for many years ahead. And as I've had time to re-evaluate what I am going to do with the AWD and the realisation of how rare a car it now is, esp in Ireland (Only remaining 1 of the 5 originally imported for sale in 1996) I feel the expense is worth it. I've budgeted for it and have the money set aside as it will only add to the value of the car as the years pass by and it becomes even more rare. Alluding to a post i have in my build thread there were only every 309 RHD versions of the 855 AWD built. 245 of which were sold into the UK, 5 into Ireland and the remaining 57 sold to RHD markets world wide. Considering the expense put into the car since 2011, it makes sense to do the final push (with rebuilt gearbox, awd system, suspension, interior, wiring, and due to its aforementioned rarity etc.,) and have the car running again by early to mid-2019.

Also ,youre being hypocritical, youre willing the run used internals yet you wont run with a used sealed engine? Doesnt make sense mate. A half arsed build wont last 5 minutes. You dont need to do it expensively sensible, just do sensible. If that means using a newer engine as a baseline then tbh why would you consider anything else? Only looking out for you man, apologies if i come across abrupt but when youre considering spending a fair figure on something, ploughing money into one option without understanding or considering other options isnt very savvy.

]Mahle or AE make the factory pistons.
Hah cheers I didn’t know that as presumed incorrectly off the top of my head mahl etc were aftermarket. 😋 Still able to get the standard bearings with the bearing numbers so all good with that. polished bores arent a good thing. It means they dont let oil 'hang' on the honing, therefore wearing everything out quicker. Thats rings, cylinders and piston skirts. Probably didn’t explain that properly as I’m not trained to give a good description of the interior of an engine. But mechanic has all his own machinery to do engines and with years of experience behind him and his crew I’m happy to let him make the choices in the rebuild. has he mic'ed everything and plastigauged it twice? theres no way he could determine it acceptable to build on in such a short space of time with no more than a visual inspection. Ive been part of a fair few forged bulds now and ive yet to find a block thats ready to go without a rebore. Ovalised and bowed cylinder walls are terribly common on a 20y/o engine, regardless of mileage, hence my suggestion of using an RN 2.4 T5 - far younger, more likely got better cylinder walls thru running a slightly longer rod so avoiding thrust wear on combustion stroke. As above he is best able to make those decisions on exploratory work. Not me 😂 Also ,youre being hypocritical, youre willing the run used internals yet you wont run with a used sealed engine? Doesnt make sense mate. A half arsed build wont last 5 minutes. You dont need to dont it expensively sensible, just do sensible. If that means using a newer engine as a baseline then tbh why would you consider anything else? Yeah I hadn’t thought about that when I said I was going to use old internals. May have written that incorrectly as as I’ve made up a list of required new internal components the engine will be rebuilt with new parts. Only looking out for you man, apologies if i come across abrupt but when youre considering spending a fair figure on something, ploughing money into one option without understanding or considering other options isnt very savvy. Cheers I put down your abruptness due to England throwing away the game there😂😂😂😂 Thanks for advice on the 2.4 RN though.
