V40: - Engine has intermittant fault and often blowing blue smoke

1981volvoguy · Mar 26th, 2013, 05:26

Hi,
I have a 1997 Volvo V40 2.0 petrol non turbo, It recently dveloped an intermittamt issue where i suddenly get a lot of vibration and hesitation from the engine and intermittent significant loss of power at the same time. It also blows blue smoke occasionally and a lot when, ( sometimes ) accellerating or coming off the highway.

I took it to my mechanic to check it out,

Got compression tests done;
Results 160 - 180 psi, no cylinder below 160.

He suspects the valve stem seals, does anybody have any ideas or can confirm this diagnosis.

Exhaust stinks like hell,

Cheers
John

Have you driven it like a nun for its life? If so it does sound the likely culprit.

Thanks Anadinolan,

Haven't been too hard on it, currently has 195K Km on the clock, I have had it since 145K KM 2 1/2 years ago.

Mechanic now reckons it might be the oil seals as on investigation the valve stems are protected by a a shield that prevents excess oil entering the top of the stem.

may need a new engine ??

Luckily I have fitted 4 new tyres in Jan when it was still running fine.

Hi Everyone,

I have investigated the problem more and found a different mechanic that is Volvo accredited.

They identified the problem as a faulty ignition coil which they replaced during the diagnosis session. Very professional, efficient and knowledgeable, if anyone needs a Volvo Mechanic in Adelaide I would recommend, "Pulse Auto", absolutely top Class.

They have noted that this will also have contributed to the Smoke issue.

Cheers
John
