Kane, you have a PM.

Being an engineer

Cool, same. Engineer of what? What qualifications?

Magnets won't hurt but you won't collect much from an aluminium engine but like you say, a small percent of the engine will be ferous metal.

Re: After Market Sumps

Never seen a plastic sump before. Being an engineer, intake manifolds I agree with, but alloy or steel for a sump seems best. I can see why technology is taking over, especially if it's cheaper to produce plastic engine parts.

If it was me wanting a drainable sump, I'd probably buy one from smarttune.co.uk. There will be a little oil left in the bottom, but not much. If the car is jacked up slightly, you might get more out. To be honest, half a cup full of old oil isn't going to do any harm. One thing I've done is stick a magnet on the oil filter (spin-on type), to help collect metallic particles. Not sure if that works? Are main bearing shells magnetic?

Re: After Market Sumps

I see the Mercedes C class now comes with a plastic sump. Material is DuPont™ Zytel® 70G35 HSLR which is a glass-fibre reinforced nylon.
Even some lorries come with plastic sumps these days.

Re: After Market Sumps

Must say though, the plastic sump looks good. But so does a lot of stuff out of China - looks good, no last. Cheers.

Re: After Market Sumps

Greetings, steel is GOOD, hence why the trid is steel not plastic. The steel sump is fine, just a pity merc don't put decent paint on them - with is the problem. I'll consider a plastic sump when merc make the trid out of plastic.
Now, 'o evil one', when are your sumps with drain plug going to be available?? I rather prefer the plug to be on the inboard side of the sump, rather than on the bottom. I just have this feeling about the 'shear' strength of it when it hits something on the road, at 'just' the right height.
As to the plastic being able to withstand 1.5 tones, have they tried having a rather large person/lady, standing on it whilst wearing stiletto heel??
Smart average weight, 750kgs, speed, say 50 MPH, hits brick on road, transferred energy, greater than 1.5 tones. Result, split sump, you might be lucky to see the oil slick build up on the rear window before the engine 'spits' the dummy??????????? Ouch, 2000 quid down the drain. -- No Pun, intended.
Cheers, Ian.

Just don't hit anything - crack - leak - boom

The plastic pan is rather thick. Prototype was tested to 1.5 tonnes before developing cracks.

Re: After Market Sumps

Agreed, hence the redesign. Ours will be chamferred and surface mounted, and properly rust protected.

I have fitted a plastic sump.

Made out of fibre reinforced nylon. No chance it will rust. Drainage is best in class.

Total cost was only 80 pounds including delivery. Came with German fitting instructions, sealant, 5 spare washers, stainless steel bolts and a brand new original oil filter.

Heat loss from the plastic pan is about half that of a steel pan so engine may heat up marginally faster. Not much of any issue for a petrol but a great bonus for a cold running Cdi.

There also appears to be less noise from engine.

Re: After Market Sumps

i used to use engine flush in my city coupe.
added the flush, run it, suck the oil out, fill with oil, run again, suck, and fill with fresh oil.

each to here own though i suppose

Considering you can only get 90% of the oil out using a pump and that engine flush loosens a lot or crud from the engine, you probably have a lot of loose crud and engine flush still running around the engine because you won't have got it all out.

Be aware that the threaded boss on most modified sumps form a mini Hoover dam leaving lots of oil behind.

Re: After Market Sumps

Both the sump with a drain and an oil removal pump are single purchase items so in the long run it's cheaper to buy the pump and it's cleaner, however it's not as efficient at removing the oil, you can't use engine flush and is a slower process.

Re: After Market Sumps

no - we're gonna knock a hole in the bottom of the old sump and drain it that way

What you haven't realised is that a number of sumps get changed when they pin-hole! In which case, there won't be much oil in it anyway!

I'm in the middle of scrapping a car just now - to get the bits I want, I don;t care if some bits I don't need get damaged in the process!

Angle grinders and cars - fabulous fun!

thats why i greased my city coupes sump, and my forfours. just incase it corroded to the point it started leaking

Re: After Market Sumps

i sould have really made myself clear.
your going to have to buy the tool to suck the oil out which will cost arround £10-£50 depending on what you get, then your going to buy the sump with the drain plug, so the oil sucker is going to be gathering cob webs, and will be money wasted.
