Double drain plug washer
 

Today i changed the oil on my XC60 D4 and later realized i made a very dumb mistake.... Accidentally left the washer on the sump and put a new one on the plug. :shocked:

This is not my first oil change by any means and never happened similar. Can it cause a problem in the future? Can the plug loosen or leak oil?

I torqued it well and felt the washer is tightening completely.

I don't want to drain the expensive Liqui Moly oil if the 2 washers doesn't cause problem. I will keep my eye on the plug btw.

Any comment is appreciated :_:

I have done this before on my 240. Never leaked. Can’t say for sure yours won’t but as long as it’s tightened good you shouldn’t worry. My 2 cents.

Even if it would leak(which i doubt)....it would be no more then a few drops a week.
Normal oil checking with the dipstick and or oillevel sensor should be preventing any (remote) trouble

Next oil change dont use 3 😁

I nearly did this on my last oil change. Fortunately, I spotted this in time. I used a genuine Volvo oil filter which came with a new sump plug washer.

When do mechanic, I always sort all parts what I need. Never know..

Thank you all the replies!

I checked the drain plug every weekend and fortunately there was no leak at all.
I have a super organised workshop and all my tools have a exact position in order to eliminate missing tools and accidents (torx bit in engine cyl, microfibre towel in fan shroud etc..).
I always work per my own check lists and Volvo workshop manual.
But of course this is not my main job only a hobby and now i made a small mistake by applying double washers. Lesson learned.:_:

Thanks again all answers helped me to sleep well after this thing. :regular_smile:

Sounds like my own level of OCD.

Dont forget to make 1000 i shall never sin prayers at the volvo altar:tongwink:

Just a quick follow up, yesterday i changed the oil and inspected the "famous" double washer.
There was only a very small oil leak but no drips. :cool:
Btw i was careful this time and removed the old washers. :tounge_smile:

Thank you again the support!
