What a lot of crap!!!! change sump plug with every oil change. Washer OK if needed.

Didn't need doing on any of my previous cars. So are the sump covers or plugs so inferior.
To need this much attention?

Example had an Australian (parts Jap:, Aus: assembled) Skyline, for sixteen years from new
covered 200,000Ks, can only remember changing the sump plug once,
Washer, yes on occasion if it looked to need it. No problems!!

Engine still mint condition when I decided to change over.

Ive seen and herad of this happening, i believe its because cars are slowly changing from metal sumps and plugs to more eco-friendly plastic setups. This negative of this is that the plug in particular wears very quickly, but is cheaper to replace.
 
With the cars at work, newer small capacity motors actually use a plastic sump plug and a plastic sump. The plug must be replaced everytime the oil is. (The same as many transmission pan's since early 2000's). As Donki said cheaper to replace the entire plug than just the o-ring, and also to note is how flimsy the plug is. I'd imagine it probably deforms a bit too.

All others are steel plug in an alloy sump or if you go reaaall old, steel plug into steel sump. On all steel bolts we replace the copper washer each oil service, and only ever the bolt if it has suffered abuse from poor workmanship prior. Always replacing the washer is a bit of CYA (covering your ass) on our behalf.
 
Difficult to get under car at my age!! Isn't sump and plug steel in myMY15 CJ lancer?

If it is, makes me want to chick the car out!!!! Wouldn't have bought it if I new it had el cheapo sump!

PS can a steel sump be bought if it is plastic?
 
:DChecked with my Mitsubishi dealer, both sump and sump plug are steel. Thank God!!!!
 
Mines an MY15, I only replace the washer every few oil changes. Never had to change the plug yet
 
Owners handbook says plug and washer should be replaced every time.

Bet dealers don't do this either.
My car still has another 3 free services to go. Will mark the plug and see what happens!
 
As sump is one of the major items prone to and that can be affected by stone, boulder and high items .
To me plastic doesn't make sense. Plus its one of the the most taken off and put back on items, in the car.
Even a child's (substantial) toy on the driveway could cause havoc!!!

In many instances Eco friendly is a word used for ell cheapo!

Agreed, personally not a fan, but mass production, cost per weight and "strength" per weight - plastic wins for many applications. Rocker covers, intake manifolds, ect. It's the future, and we don't have a choice haha.
 
Agreed but the locations you mention seem appropriate . Lets hope they keep it there.

Not sure about inlet manifolds though! Can they be water cooled or don't they need to be?
Yes I know mine is plastic!
 
Inlet manifolds are fine in plastic, I'd be more concerned about plastic rocker covers hahah

On some new "B" generation BMW motors, they now have an integrated coolant circuit through the intake manifold, but these are aluminium not plastic.

I think with the plastic there would perhaps be too great a difference in temperatures in different sections of the manifold for a cooling circuit and there's probably less heat transfer from the head into plastic anyway.

Had them for years in Euros.. They're really cool for integrated PCV piping/valves, and keeping weight down.
