Help!

Firstly 4 weeks ago I broke the sump without realising on a rough road and ran on low oil for 2 miles until engine stopped.

Then replaced sump and oil and ran for 10miles before losing power and cloud of smoke from exhaust. I assumed broken turbo and engine damage so sourced a second hand one.

Have put engine and turbo in now - started immediately but at fast idle liquid oil is pouring from exhaust pipe with only minimal smoke. (at least 2 egg cup fulls)

Is this likely to be a turbo problem or engine? Obviously v frustrating to spend 3 days swapping engine over only to find I've put dodgy stuff in! If it's just the turbo this is easier to sort.

The original turbo looked obviously damaged when removed with lots of play in axel/shaft. The 'new' one had a solid axel.

Engine and turbo bought via e-bay with alleged '2 month warranty' - don't fancy my chances of much refund though...

Could it just be what was left in the system from your old engine failure?

Maybe run the engine for a while to see if the new engine is losing oil and any more from the exhaust.

What he said.

The oil from the previous failure will more than likely be pooled in the cat, pipes, boxes, etc and is likely to take some time to eliminate.

Don't stand behind the car when the engine is running or park with the rear of the car facing white walls. :eek:

i agree, have changed a few engines in cars at work, took exhaust off, and left it up right in a bucket, there was probably a good 1l come out of 1.

Thanks! This is slightly comforting. Need to sort the gear-selector and clutch out now and give it a test drive! Certainly nowhere near a litre out yet, and I guess the fact that it's not v smokey and is actual liquid means it's unlikely to be engine/combusted.

I guess come MOT time it would fail emissions and need a cat, but just to get it that far I'll be jumping for joy!

No emissions test in UK, just smoke test.

when you get it back on the road, drive like it's stolen for a while, 3000rpm+ on motorway so that the heat and pressure blows out the remaining oil. That will take care of soot and anything that got fixed to the walls by the oil in the exhaust.

Most of the oil will get blown out. New engine oil does very little damage to the cat (which is the case here). It is the impurities in used/cooked engine oil that can poison the cat and reduce its efficiency. The cat operates at high temperatures so will be clear in a few hours of normal driving.

Asked a friendly mechanic and apparently also when original turbo went it would have squirted plenty of oil into intercooler. Took that off today and swilled it out with petrol and plenty of oily sludge in there! Car certainly seems to run OK and oil level maintained but smoke++ on motorway. Am waiting until it's dark to burn it some more so less conspicuous. Will be great if CAT isn't damaged too though.
