156 Sportwagon

Hmmm 156 Oil Level Conundrum

Firstly, I although a design engineer, I no rather little about the workings of internal combustion engines so please be gentle

I have a 156 2.4JTD Sportwagon (2001) which I imported into Ireland recently from the UK. It was serviced by a trusted specialist in the UK just before importation and runs sweet as a nut. As part of importing it it has to undergo an NCT test here in the emerald isle (similar to UK MOT).

It failed the first test as they thought the oil level was high (when I checked the stick it did look high). I took the car to a main dealer in Dublin and asked them to change the oil, which they did, and the oil level looked OK afterwards. Took it for a re-test and it failed again on high engine oil level. Took the car back to the dealer who confirmed this is correct oil level, and wont touch it.

I have two questions
1) The oil level generally seems to sit just above the flattened area on the dipstick. is this actually too high?
2) How much influence should the engine being hot / cold or just turned over have on the level
3) If I need to take matters into my own hands and dump out 1/2 a litre, any idea what fiting the sump plug is so I can run out and grab the tools?

Any help greatly appreciated, as my third test is on Thursday and if I fail this......it won't be good. The car is going back to the main deler in Wednesday to resolve another (electrical) fault, so if possible I would to get them to finally resolve the issue.

Fails for too much oil How strict???

Can you change the oil yourself? Drain it and refill with the quantity staed in the handbook. If it still shows too high drain a bit off for the test.

The oil will increase in volume through expansion (not much surely?) but would take this into consideration?

Re: 156 Oil Level Conundrum

I've never checked the oil on a JTD, but I can't see it being much different to a TS setup.
On the TS you need the marked side of the dipstick facing the engine and don't twist the dipstick. Because it goes in at an angle, one side (the unmarked side) will read higher than the other.

Re: 156 Oil Level Conundrum

Checking the oil on a JTD is a pain to be honest...I have to do it two or three times and even then I'm not sure...and that's with using the trick mentioned above.
