Odd feeling

Jim Haseltine · Apr 23rd, 2011, 08:38

Difficult to describe, but recently when driving I've felt something a bit strange.
Crusing along, constant speed (usually around 70), constant revs, when with no warning it feels as though the car has more power and it surges a bit. It's almost as if something has been slightly blocked and has cleared, no other symptoms, no cough or noise from the engine/exhaust, just a seat of the pants feeling that something is different. Other than that it performs as normal.
If I'm not imagining it, it's happening once or twice in a journey of 25 miles.

Car is a late Classic AWD V70.

Anything I should look at or should I ignore it?

When did you last do a service. Could be that you are running on 4 cylinders and occasionally all 5 are firing?

ETM?

White or yellow label?

Yellow label. What's the difference? One colour suffers the problem more than the other?

It is coming up on service time - I'll have had it a year next week and it was (supposedly) serviced before I bought it. Certainly had clean oil and a new air filter because I checked them but I didn't take a look at the plugs.

I want to do the cambelt soon so I'll probably do the lot in one go. There are slight traces of oil under the top cambelt cover - little specks of old, sticky oil that looks to have been thrown off by either the belt or the cam gears. How difficult is it to change the cam and crank oilseals?

Lots of problem with white label, I believe I'm right in saying the yellow label ones were an upgraded part, so good news there. Just a thought!
