147 1.6 TS Heavy oil consumption and blue smoke
I'm really confused by this one now. I know these engines like a drink of the brown stuff, but it has used about 2 litres in about 200 miles!
It puffs blue smoke abit on start up, then accelerating (not hard) from a standing start through the gears. Once warm, it smokes worse over 3,000rpm but doesn't smoke when cruising or at wide open throttle at low revs.
I've had the inlet manifold off today and re-sealed it, so its not the variator solenoid leaking into the inlet. Compression check on a warm engine results are as follows:
1 - 180 dry, 205 wet
2 - 190 dry, 210 wet
3 - 195 dry, 220 wet
4 - 185 dry, 210 wet
All plugs looked normal, not wet. If anything it looks like it's running a little rich but the exhaust is blowing so I'd expect that.
Appreciate they have all increased with abit of oil added, but the dry figures aren't excessively low and I wouldn't have thought low enough to get through so much oil if it were piston rings?
The head was off recently to replace a damaged valve. At the same time it had new valve stem oil seals and a gasket set. I'd be surprised if it were stem seals as they all went on ok and seemed to seal fine against the valve stems.
The only other thing I've noticed is a couple of exhaust manifold studs are wet from oil. It's obviously losing abit here but I doubt it would account for the whole problem?
