Duratec Dry Sump oil change

When I get my car back at the end of the week, I am doing an oil change, removing the Miller CRO 10W/40 running in oil, and replacing with Millers fully synthetic 5W/50 that was supplied with my kit.

I have been given differing advice on the oil drain and refill process. I thought I'd document what I think is the best way, for you guys to review, so I can get a definitive process, and maybe help others in future too.

1. run the car for a few minutes to get the existing oil warmed through a little.

2.  Don't use the sump plug on the oil tank, as apparently its soft and easy to damage the thread. Instead, unscrew both the inlet and outlet pipes at their sump attachments (there is a sacrificial section on the sump in case of any tragic threading, and a LOT cheaper than a new oil tank). 

3. Remove and wipe out the "finger filter" rear LHS of engine

4. Remove oil filter 

Then in reverse pretty much, and when everything is tight again:

1. Replace oil filter with a new one, add a little oil into it before refitting

2. Fill 1 litre into the top of the engine and 4 litres into the dry sump tank. 

3. Unplug inertia switch to stop fueling 

4. Unplug crank position sensor (front RHS bottom of engine) to stop a spark.

5. Crank engine until oil Pressure is noted.

6. Then slowly refill to the top of the 1st baffle that you can see in the oil tank.(potentially around 7 to 7.5 litres).

7. Plug crank position sensor and inertia switch back together.

8. Fire up normally.

 

Does this process sound correct to everyone who has done this before? Anything amendments or alternative perspective would be much appreciated.

Thanks

Marcus

No need to remove oil pipes, next to nothing comes out if you suck tank dry win Pela pump and drain at finger filter after warming.  Change filter and refill with the same amount drained.

Check level after running.

Agree on the use of a Pela vacuum pump/excavator; makes the whole process quick, clean and easy. Well worth investing in.

When I change the oil and filter on my 500D (same configuration as 400D, I'm assuming) I typically find I've manage to remove about 6 litres (maybe just under) of used oil - which becomes the quantity I then add of the new stuff.

Pela Vacuum sounds like the order of the day for me too then, which one do you recommend?

I have a Pela 6000 (6 litre). Had it a few years and it works OK.

Actually, I would recommend the HD 6.5 cylindrical one (also sold as Sealey TP69 I think) but it's quite a bit more expensive. That type is better though, IMO.

Wonder if this would fit the bill as quite a bit cheaper!

Yes, similar to 6000 but smaller which would make change a little messy as you couldn't empty tank in one 'suck'

You can get the 6000 for £30 or so, the HD 6.5 for around £48 I think. Well worth the cost to get a good one.

Never even heard of these! So do you suck the oil out of the top of the tank then? Is it really that simple?

I have found that the easiest way is 

1) warm up engine 

2) blat to Nick Potter 

3) drink coffee and play with dog while Nick does his thing 

4) Hand over a small sum od cash 

5) Blat home via some far off spot the other side of Lincoln

Also interested in where the oil is pulled from, the tank I presume?

Get the bigger pump. You then won't have to empty it halfway through the process. It really is as simple as sticking the tube into the dry sump tank, pumping the pump handle a few times and sucking the oil out. I don't even bother warming the engine. There is very little oil in the sump so not essential to drain that but if you have a sump plug then you could drain the sump too (my Raceline sump doesn't have a plug).

I have a Pace easyclean tank and I just remove the centre breather to get the pump tube down to the bottom of the tank - I guess it's probably similar on the Caterham tank.
