1998 S70 T5 PCV relief?

Post by **erikv11** » 23 Oct 2015, 17:20

Super rare for a 150k turbo to be bad on a 98 S70.

A good online rebuilder is G-Pop shop http://gpopshop.com/, they also sell turbos if it comes to that.

Paying a dealer to do these simple maintenance jobs will quickly surpass the value of the car. The real value of this website is the detailed info and help you will get to DIY your Volvo.

First thing to do is take a compression test. If it's very low, or there's a bad valve or cylinder there is no need to spend money on PCV systems or turbos.

You seem hung up on making assumptions as to just what's wrong, and you're OK just throwing money at it. Sorry if I sound harsh but I'm trying to save you potentially a LOT of money

unfortunately, the dealer doesn't care but just curious.

You do the T-belt when it's due. When was it done last? Do you have any records?

Huh? Why do you think smoke = pressure? If you remove the oil filler cap off of an engine that is 200+ degrees, and the outside temp is lower than the 200 degrees, smoke will come out.

The PCV and timing belt is not connected in any way. The only benefit in having both done at the same time is that you only have to drop the car off and pick it up once.

Is this tread real? I feel like this is myth busters for Volvo's.

Tons of PCV's are bad and need/have been serviced with NO effect on the turbo.

This ^^^

But, if you are ready to pull the trigger on those maintenance items, I doubt you'll do a compression test.

A super clogged PCV will dump oil into the turbo and pour smoke out the exhaust, my GLT was like this when I got it.

Is this if the "catch can" is full? The PCV system is supposed to dump pressure into the intake pipe, some oil travels with it, and then it's in the air flow. All of my Volvos have had oil in all air hoses - it's supposed to be there. Though, the amount can probably be discussed from here to sunset.

As for the OP...
- A '98 S70 T5 doesn't need a new turbo unless it's been physically damaged. It's not worn out, and it still has thousands and thousands of miles left in it. Leave it alone.

- You can handle the PCV job yourself. The first time it can take you a day, but then you know it.

While these cars will run hundreds of thousands of miles, the cost of them comes from dropping it off at dealserships (stealerships) for minor maintenance. Don't do that. Check the DIY database here, and don't be afraid to try doing things yourself. The worst result you're likely to get from a DIY is that the car gets mad at you and won't start. And then we'll tell you how to fix it.

I've done many repairs myself but at 62 with arthritis, it's not an option on some repairs. Getting under the car is impossible for me. Anyway -- thanks for the info. The compression seems good, mileage is about 19 city so there you go. Getting this PCV repair done will give me peace of mind. Thempg did drop off (17 or so) with some sluggish performance a couple of months ago -- so hopefully it's related to the PCV/turbo issue. New plugs, new plug wires, new rotor and cap about a year ago. Timing belt won't be due for another 20K.I use synthetic mobil 1 oil and tran fluid, drive like a grandmother and shooting for at least 200K with this car. I don't know what my next issue will be, hopefully smooth sailing till then unless someone can also tell me some things to look out for.
Given up on the *^$()( ABS module and the P0442 code (maybe the PCV rebuild will fix that?). Keeping my fingers crossed the transmission will keep going without problems. Engine "sounds" good.
