Smoky, smelly and slow.

Just noticed the oil was over filled about 1/4 of a litre. may have been more as it's been driven about 150 miles since it was last topped up. I only checked to see if it was sludgy not the level  :embarassed: What have i done to it?
Just drained off the excess cleaned everything i can get to, put in fuel cleaner and run it for a bit to clear it out.  Still weird exhaust.  Help

Over filling oil increases the oil pressure, a little bit over might make it smoke a bit but too much causes damage.

Oh  Thanks for the reply. What sort of damage should i be checking for?

over filling oil dosen't increase oil pressure.   1/4 ltr isn't going to do any damage ether

if you extreemly overfill oil the enigne will start blowing oil out the breather or the cranck will start whipping it up,  usual result is a big plume of blue smoke from exhaust and it'll murder the cat and any lambdas  but a mk2 don't have a cat or lambdas

I would be looking at the cast exhaust manifold. These are known to blow with age and can cause a drop in power and the noise you describe. THe smoke is more likely related to your over fill of oil.

Thanks I will check it out.  Would a crack in the eqhaust there change the exhaust note actually coming out the tail pipe. it doesn't sound like its coming from the front?

It can do.
