Hi,

 

I have a 1.9tdi octavia. Seems to be abit of swarf on the dipstick (206k miles).
Been told to drop a litre of oil, put a litre of diesel in, let it run for abit, then drain it all out, and put the new oil in. 

Any advice on this? 

This sounds mental to me. PD engines are quite sensitive to oil so I would be worried about buggering your injectors.

 

I'd just get the engine good and hot, stick it straight up in the air and change the oil and filter for a good quality one, and hope the grit had gone away!

is not a bad advice,I would rather use a CRC engine flush wich is very good and powerfoul

most 'proper' oil flushes are only paraffin anyhow so what you're proposing is no different however i wouldn't do it on a pd lump if that's what you have.

It's a 2003 Ambiente (is that right?)

So unsure if it's PD or previous. Don't even know the bhp, but presume it's 90bhp.

already blanked the egr, cleaned it, took inlet manifold off and cleaned that too (best i could) that free'd it up abit, but still no rocket ship. 

flushing the engine will also flush the bearings...   its scetchy....

 

drain the oil....fill with new oil... run it up to temp.. and change the oil again.... safest option in my opinion... 

Update for any curious.

I drained the old oil out. 

Put in some 5w-30 my dad had in his shed. Ran it up for about 5 mins then drained that out. 

Took old oil filter out, and got as much out of the oil filter housing as possible. 

Filled with fresh oil (from VW as was the filter) and then tightened the sump plug when I noticed a big nut under the oil filter housing/pump, I think if I undone this I'd of been able to get some more of the old oil out? 

Anyway, first oil drain was black as you like, No swarf though. Oil must have conjealed abit because it was sat for 6 months when I initially checked the car over.
Second drain, still black as you like. Again, no swarf, noticed a small small amount of debris in the oil pan, but could have been from anywhere.
Then the new oil and filter, after a couple hundred miles, It's not "clean" but it's not as black as the second flush either, so that's something.

Also flushed the power steering fluid, which was pretty dark in colour, and filled with new. Quite easy, and can be done without getting underneath the car. Hardest bit was fitting my cut up bottles in to catch the fluid! 

Your new oil will be black after a very short period as you have a diesel engine!

If in doubt use a cheap oi/filter and change for some good stuff soon after

ahhh I see gone are the days where my 5 month old oil was still the colour it went in.   

power steering fluid that came out if anyones interested.

Car is on 206k so I guess it's that old. 





It looks worse than what it was. I don't think any ATF was added judging by the colour. But all fresh now
