Engine Running Without Sump

[FireFox]

This is an old Lancer that was destined for a scrap yard so the guy removed the sump and valve cover and started the engine.

 

Shows the speeds the engine is actually operating at, also shows why oil is so damn important lol

 

 

The average car idles at around 900-1,000rpm when up to temperature (otherwise it's around 1,200rpm or so) which is about 16 revolutions per second, while driving the engine could easily be around 2,500rpm (depending on the engine and gear ratio's) which is around 41 revolutions per second.

 

The amount of cars we've worked on because people seem to forget that oil is needed and run it for years is barely anything in is insane and the fact that it's so easy to remove the dipstick and check the level once a week or so and because you generally need to fill up the screen wash bottle anyway, checking the dipstick would only take a few seconds out of your day just to check.

 

Because I don't know a huge amount on computers (a fair bit, mainly hardware) and I want to be kind of informative and helpful I thought I'd share a few things on how engines work and what not, I kind of feel useless just hanging around the off-topic section and not really contributing.

 

If anyone genuinely needs any advice on this kind of subject then please feel free to send me a message and I'll try and help to the best of my ability.

First time I've seen an engine run without the sump... nice! 

 

At this rate, there should be a sub forum for car discussions :P

Would be pretty good, I'd like to contribute but there are a lot more people better than me at computers so to be honest there isn't much point in me taking part a lot of the time

 

I know a fair bit mainly about hardware but can only speak from experience and most of the issues I've seen here I've luckily never en-counted so a lot of the times I'm not really sure what to say other than trying to think methodically.

I drove an old moped without oil for a fair amount of time. It was a two stroke but only the left cranckshaft bearing was oiled through the gas, the right one needed ATF.

Fourstrokes need oil a lot more, especially for the camshaft and the crankshaft which are both (usually) plain bearing :D

My mom drives a Rover and the head gasket blew once, putting coolant all through the oil/oil through the coolant :D

Luckily the damage wasn't too much

2 strokes have oil mixed in it with its fuel. So were you running normal unleaded?

thats depressing seeing motor's die like that, I much prefer it to happen like this

Have never seen this done intentionally before or with the sump completely removed, had to be a fellow Irishman :lol:

Did better than I would have thought, nice post :) Agree on the car subforum, most other tech sites have them.

It is had the Rover K Series engine then they are prone to head gasket trouble, mainly due to the engine having a sandwich construction and as a result there is too much movement

Of course it hat oil through the fuel, otherwise it wouldn't have survived one minute

The oil in the actual engine was missing

Two stroke engines don't hold any oil within the engine at all, maybe big two stroke diesel engines do but I'm not sure, I'll have to take a look.

I saw video where 2 guys did this on ford sierra -> went up in flames.

Really damn

But they do. Transmission needs oil as well

Would you like to post a picture, the small two stroke engines I've encounted don't hold any oil inside the engine like a four stroke.

 

All transmissions need to have oil in them otherwise those gears won't last that long

 

Also here is a crude video showing how a two stroke works

In a small engine I can't see how they would work if they contained the oil inside the engine

I think we had a miscommunication - Twostrokes don't hold oil ''inside'' the engine as in under the crankshaft/piston (because that's lubricated through gas), but it has oil in the clutch/gears department, which is what I meant :p

Ahh sorry, yea damn miscommunication stikes out of the blue :)

Oh the Irish!

I've been a Diesel Mechanic (18 wheelers) for 11 years now and its amazing how many people don't check the oil on there trucks seeing as they run nearly 24hrs a day it boggles my mind. Then they wonder why there is a hole on the side of there engine the size of there head.

Yea, big bloody connecting rods give out they make a mess.

[Nicktrance]

Yeah it's amazing to see how few people check their oil, tires, brake fluid etc. regularly, or consider oil leaks beneath the car as "normal".
