hi guys, m8 has just purchased a classic

he has loss of power and lots of smoke, he has changed the turbo but still the same. also he has compression tested and is down on No. 2 cycl...... is this a valve, piston or gasket problem.

using a lot of oil too

thanks

Head Gasket im afraid, same happened to me with my classic, better stop driving it as you are only doing more damage.

smoke is water mixing with the oil causing white ish smoke.

If it is using a lot of oil, my guess is that its a broken piston (probably the ringland)

if its just down on 1 cylinder then unlikely to be gasket as they usually go across 2 cylinders

Could this be the cause of my problem?
i lost all power and had white smoke from the engine on monday, i have the post "My Subaru is Dead".

The compression test said cyl 2, so if its not the gasket then as said b4 its prob more then 1 problem, best advice is to get it to a scooby specialist, and put your m8s mind at ease or at least get the problem identified.

Sry cant be more help.

Holy piston...probably.

The Impreza is known for melting pistons.

Loss of oil+ loss of compression+ lots of smoke are the very symtoms of this problem.

Either way, it doesn't matter if its rings, piston or head gasket as in all cases, the engine has to come out and the cylinder head needs to come off anyway.


If it is a piston; then ensure the cause has been fixed after the engine has been repaired. Otherwise it'lll do it again. ECU malfunction (such as airflow sensor or failing fuel pump/blocked fuel filter), dodgy modifictions (mapped "to the limit", too much boost, bleed valves or boost controllers with fuel cut bypass etc). Or using the wrong fuel on a mapped car or normal unleaded in a 260/280ps Jap import that's not been re-mapped for Uk fuel.

Also, if piston's gone, I bet the bigs ends are on their way out as well. So could well be rebuild time.
