can anyone help me please. i have a 1999 s80 t6 and ive just received the gasket and o ring for the turbo return pipe but i cant seem to see how i can get to the return pip to change them. it needs doing because it leaks oil and im forever topping up. any diagrams or explainations would be much helpfull. i have managed to change the deal & gasket on my s70 t5 which was a stroll in the park compared to what it looks like on my s80.
thanks in advance

Sorry but I really can't find anything on the S80 for the turbo oil return line. I thought there was something in Bay13 for this but I was mistaken. However, there is a hint here: http://volvospeed.com/vs_forum/index.ph ... opic=67112
Also, I know (and from reading the description in VADIS) that there are 2 turbo's...the one deals with cylinders 1-3 and the second 4-6? Anyway, VADIS says that if you change one thing on one, you need to do it to the second, so if there are 2 return lines, you should do both gaskets and o-rings. Sorry that I couldn't be more specific.

thanks for getting back to me.
it looks like i have to remove the 0/s right hand side driveshaft to make access easier. i found the turbo return pipe gasket and o ring a common problem of leaking oil as the original seals i am led to believe are red and made of the incorrect compound. replacements are green and can withstand the higher temperatures.

regarding the faulty gearbox, since you sent me the diagram, i found the leads into the four solenoids and put voltage across them to test them without opening up the gearbox, they all work fine. i found one of the negative/ground leads (marked k) an open circuit into the box an open circuit where they all connect to ground on the right hand side wing near the ecu box. a simple fix, but i have decided to replace the complete wire on that part of the circuit with better connections.

im beginning to learn about this and once ive got my s80 t6 up and running i will post some posts of how to do the jobs im doing. unfortunately, im hopeless at my computer so it will just be a brief description without pictures.

regards,
les

les,
In about an hour I'm off for about an 8 hour drive to the beach! However, though limited, I will have access to the internet and this site during my 9 days away from home and will be able to post pictures. If you have a digital camera, go ahead and take pictures- I'll help you post them.
Also, I would like to thank you ahead of time for your write-ups. Obviously, there aren't that many for the S80 as this site has been gravely lacking of content for these cars. Any descriptions of repairs would be a great addition to MVS.

hi dave,

thanks,

i will think of something, i think the best way to do it is by describing the diagram, from what i found it looks to me like a very common fault in the same area. i read the other day someone on here was experiencing the same fult code readings as i was, i will try and find the post, because if i was a betting man, i would put a bet on that he has the same fault in the same place as i did.

enjoy your visit to the coast.

8 hours drive!!!

im only 2 minutes walk from the coast here, ha ha.

reilly my german shepherd loves a walk along there at 4 or 5 am in the morning !!!

catch you later.

i am going to have another look under the car, its nearly all back together now all i need to do is fit the n/s driveshaft and bleed the brakes.

i think it may be easier for the turbo return pipes to be accessed by taking the bar off which on the body hiding the exaust pipes.
