What are the P80 V70 S70 C70 Killers & Common Faults

The aim is for the collective to create a single thread that signposts these. NOT to be a highjacking thread on how to sort the various issue, but a collection of links to the solutions.

These cars are known to be good for galactic miles with the caveat that a few items are kept on top of. I'm with RobertDIY of Youtube fame for being a great proponant of this. The things don't rot, unlike Mercs etc of a similar vintage even the W124 supposedly made of granite is rot-box by comparison. Watch a few key points, the P80 V70 S70 C70 Killers don't seem to get near us for 300,000+ miles. Few cars can do this before becoming uneconomic to run, in my experience not a P80 becuase parts are cheap and plentiful.

Doa ll you can to list what you understand to be the things these cars need doing to them to get to 300,000+

REPEAT DO NOT ENTER INTO HOW To Sort the issue or it'll bog down.

I'll kick off:

1) The Heater core. A Known issue. These leak causing head gasket failure and to the breakers piel they go. A £30 part kills many a P80

2) Overheating Auto Transmissions: My hobby horse. Manuals are pretty much bullet-proof, and so are autos if you flush or fit a cooler. Google Gibbons Flush, you'll find all you need ot know. If not most won't get to high miles. I have £50 that says your ATF is black. Damage is being done. Not an issue if you don't drive the thing, but for the rest of us...

3) ETM Late 1998/99 only. This subject ahs been done to death. You want a Sacer ETM module. Contactless, don't bohter with any Magneto Marelli whatever they tell you.

Information only. With links if you can.

Can somebody do the ABS module, door-stay, suspension bushes, etc etc. Who's next`/...

4) PCV:

This one also short and sweet. PCV puts many cars in the crusher. The factory fit system is undersized after cars get outside warranty mileages and clogs. Crankcase pressure builds, blows seals and the job to repalce these cheap as chips seals is so involved (likley the transmission is coming out) to be non-viable. Cars at 120,000+ burn oil or still have less than ideal pressures with factory repalcements. There's many ways to do this. Worst way is to fit more of the same parts that caused the issue in the first. Particualry as the engine is now getting tired, so needs an PCV upgrade. Numerous threads but this one is top of the tree

Until i did the mod. shown in this link, mine still burnt oil. £100 odd for a few bits of hose that kills these cars? - don't buy it, factory kit is overpriced junk, amounting to a few tubes. Works fine for the first 100,000. Hose is Hose. If you drive the thing, ie 150,000+ do it for less and do it better following the link above. Then stick to fully synth oil. Saves a fortune in oil too. Note: Race cars have pumps to reduce crankcase pressure for a reason, can't recommend thsi mod highly enough.

Kind of linked to the PCV avove, rear crank seal sees a few off as it's a gearbox out job to change a £5 seal.

Seems to effect earlier cars more, or perhaps they're more neglected now.

Blocked PCV puts extra strain on all the seals and unfortunately one of the first to go is the hardest to change.

Would also suggest rear delta-link bushes, as they're a ball ache to change so the cost is often uneconomical.

I did two in around an hour on Sunday.... Not sure what the fuss is about!

Yup agree with you there.Did some last year without any speclal tools.
Burn the old one out with a blowlamp and drift the new one in with a copper mallet.

There ia hole in the clip a thin cable tie saves a lot hassle.
