Hi. Does anyone know which is the appropriate turbo unit to use as a replacement for my messed up current version on a 1998 v70XC? There seems to be a few different kinds out there, but I am looking to get this on ebay and there isn;t a whole lot of detail offered there as to mathing the turbo unit to the specific engine number eg B5254T requires X turbo unit.

 

According to the link below you should have a 13G turbo.

thanks, that what i thought, but the 15g pops up all over the place and seems to be an upgrade... i am not going to mess with it, though and replace with the 13. any thoughts on where to get a tutorial/play by play on the procedure?

It's not all that bad. There might be one on Volvospeed.com
Is yours locked up?
Or is the car just smoking?

 

car is moking like a son of a gun. i was told when i purchased it that it was the pcv system, but another guy, a mechanic told me that a clog there wouldn't make it smoke like that. so i am going to do both procedures, i think. unless someone tells me it could just be the pcv. car doesn't seem to be lacking any power.

 

I would do the PCV system before sinking the $$$$ into it for a turbo.

 

thanks, that's what i thought. can the pcv be responsible for copious amounts of smoke out the exhaust, though?

 

If it is fully clogged it will continue to pump oil into the motor.

 

would that smoe get into the axhaust or just leak out the dipstick/filler cap?

 

It would pump oil into the motor and it would burn the oil.

 

thanks for the help! i am definitely going to do the pcv job first then see where that leaves me, though it seems like this might actually be just as challenging as the turbo swap!

 

It's really not all that bad just take your time and mark things and you will be fine.

 

Now I am seeing white/tan sludge on the dipstick and some streaking on the oil cap. I guess this means a blown head gasket? This is quickly turning into a pretty lame car purchase over all.

 

It does not always mean blown headgasket.
To be sure you can do a block test.

It might be there from constant short trips.

 

i hate to keep bugging you with this, but generally, how is a block test performed? and is there a link to a step by step?

thanks for all your help.

 

You will need to buy a kit from an auto parts store. It is a tube looking thing you put some of the liquid stuff into that comes with it. You stick the tube in the top of the coolant bottle with the car running. If the liquid changes colors from Blue to Yellow the headgasket is blown.

 

okay... I drove this thing a little this morning (about 4o miles) and it seems i have lost about a half a quart of oil in that time. Are any of the above discussed culprits possibilities given this huge loss of oil? I am afraid even to think of the rear main seal. it was smoking like a bastard except at around 1700 rpm where it cleared up a little. Some genius actually came up beside me in a Volvo and said "you have a blown engine, you know that right?" To which I replied "you must be a mechanic." He said "no, but i work in an auto parts store."

 

It is possible. I would check the things listed then go from there.

 

Well, I pulled the PCV system apart and was astonished at how clogged it was. There was no way anything was going in or out of that box, and furthermore, there was a small vacuum hose that is supposed to connect to the intake manifold that was completely hamburgered and just hanging there. I wonder if this was the start of the trouble and whether this hose's funcition is one of vacuum and keeping things flowing in and out of the fire box since it is connected to the intake manifold.

We then took a shop vac and cleared the blockage in the lower firebox/engine block inlet and it finally broke free and yielded a ton of very, very dirt brown oil, but happily not streaked with antifreeze.

Question is would this type of blockage lead to oil being blown up and out of the filler cap and out from under the valve cover?

Thanks,

Liam

 

Being that clogged with build so much pressure it will blow seals out.
