View Full Version : This is very funny (engine blew up)!! hahahahah
Ok so its NOT funny but you got to laugh coz otherwise ill cry then smash everyting in sight. Its not totaly blown up either. OK so its totaly my fault. I let it run VERY low on oil, why? coz im a fool! So the damage is a knackered crank and shell bearings. Everything else seems fine. i have been told the crank cant be re-ground and they dont have oversized shells. I have been told a new crank is £714!!.....NICE!!......i may have to buy a new engine off E-bay for about £400. its harsh i know but i have no choice now. I have bought a kawasaki ZX7R ninja to get me about on for now. Its a '98 model zx7r and will do the justice till my baby is fixed. i thought id share this with you all.......Mart

Got to laugh or you'll cry, eh :( Just sent you a wee PM...
Im just counting time till mine pops, makes some odd sounds sometimes. Its been down several times still running for a while after, done a stressfull Euro trip and running very very low on oil. So i dont expect much more from it, but who knows..

Seems to be a recurring theme on here, engines failing after low oil. Is the SV engine particularly prone to it or are we not good at checking levels, as a group?

They're maybe a wee bit more sensetive to not having enough oil than some engine... I ran my Virago with less than 300ml of oil for, ooh, probably ages and it was fine. Well, it was a wreck, but the engine was fine... Can't do that with an SV. But at the end of the day it's still operator error unfortunately.

Unlucky skulpt. I've got 2 engines for a CG125 in my garage if any parts will come in handy ;) lmao

Yep, good point. Pretty rare though, unless one of the drains hasn't been fitted right.

The warning light on both SVs (and most bikes) is oil pressure not oil level, do not get these confused or, well, you'll spin your big end bearings.
So Baph, what happened to the CG? Well curious now...

:oops: oil pressure?? against what?? :oops:
Yes folks the funny thing is i was intending to do a full oil change that same day but was waiting on a filter. This is the first and last time i do this ever again..

was your light on??
& what dose oil pressure mean?
So Baph, what happened to the CG? Well curious now...
Started her up for my commute home, and knew something was wrong, clutch out, and an odd noise when in neutral. But I checked the oil, and it was a little low, but nothing too serious. Thought nothing of it, afterall, CG's are pretty bullet proof, right?
So off I toddled.
Came to the A55, a good 40mile from where I'd set of, and all of a sudden the rear locked up on me, pushing the top side of 70, overtaking (downhill with a good wind behind me :lol:). This caused several problems:
1) BIG black line down the road, leaving a nice flat spot on the tyre.
2) Similar line, but different colour, and a little closer to me than the road. :oops:
3) Me, stranded in the middle of the A55, with 2 mobile phones :)
4) One mobile had a flat battery, the other no credit, and a quickly dying battery.
So had to call out Plod to help me off the A55.
Still haven't gotten around to looking at exactly what went wrong, but she definately still won't kick. Couldn't say no at the cost of the other engine, £35.
Sorry for the derail folks, but he asked :oops:
Hovi5, I'm told, that if the oil light comes on, about the only thing you can do to prevent too much engine damage, is hit the kill switch & pull the clutch in. Do it fast enough, and save the engine.

:oops: oil pressure?? against what?? :oops:The sensor! Oil pressure is built up by the oil pump to push the oil around the engine. Most engines will have an oil pressure sensor to warn of low pressure which can lead to damage and can be an indication of low oil level.
However the sensor might be placed in such a way as to be no use, i.e. by the time the light comes on, vital parts are already starved of oil, engine goes bang! Looks like the SV oil pressure light is in this category. Check you oil level before every ride.

Oil pressure is the pressure at which your oil is. When pressurised. If it drops, it's because there's not enough oil, or because of the oil pump. The oil doesn't just sit in the engine, it gets sprayed all over. That's why oil level meters are hard to do right- the casing's full of oil mist and spray, there's the main jet doing its thing, and the crank and rods thrashing around at ridiculous speeds. Think of using a powerwasher inside a shed, then imagine the shed has a massive, 9000rpm fan in it...
:smt017 whats the point of an oil pressure light? a warning light to tell you your oil is low would be better

That'd only work on a cold engine. Once the engine warms up due to running, you have the fine mist sprayed around (reason given by northy for dipsticks being crap).
If you're thinking a float like in the fuel tank, think of all that high pressure oil pushing the switch back & foth. It'd flash constantly.

I did the exact same thing, so I bought another engine for £300 delivered. Thinking of getting my original bored out to 700cc in a few years time when i come to sell the bike.

STEP 1: Check the oil when the engine is warm. Oil expands when it's hot and contracts when it's cold; different temperatures will give you different readings.

"Engine oil level check"
Follow the proedure below to inspect the engine oil level
1)Start the engine and run it for a few minutes
2)Stop the engine and wait for three minutes"
There should never be any risk of starting the engine with a dangerously low level, since oil doesn't vanish. If i start my bike tomorrow and there's no oil in it, then either there was no oil in it when I parked it tonight, or there'll be a load of oil on the floor.
:winner: razor, looks like YOU will be needing the muppet emoticon after all :lol:
I actualy did think the light was an oil level light which is why i let it run so low. Well you live and learn. I wont do this to my ZX7R that is for sure!!!!

One of these threads "I blew my engine up after running low on oil" should be a sticky on here really.Don't matter which thread as there's plenty to choose from.
As for whether to check it hot or cold I don't think it matters much,but what does matter is that you check it often,like every few days,or every few hundred miles.
northwind
14-12-06, 09:26 PM
I check mine very rarely tbh, I just observe whether it's burning or dropping. Since it's doing neither, I probably check it about once a fortnight. Not recommending this as a course of action, but over that sort of timsecale any losses should be visible. To me, at least :)
Still. If everyone spent as much time checking their oil as they did talking on the internet about which oil to use, less bikes would blow up :)

It doesn't matter where the oil pressure switch is placed, it's on the pressure side of the pump somewhere in the pressurised oil, doesn't matter where in that system it is, if there's pressure the switch will be pressurised. Suzuki haven't put the switch in the wrong place.

Call me anal if you want but I cannot believe the number of peeps on here thta have written engines off because they did not, don't know how to check their oil level. Surley this is one of the basic safety checks, I for one am willing to help anyone on here out who needs a bit of education. You never knopw all that boring stuff you couldn't be bothered to listen to or read (owners handbook) might just save you a load of cash.

Sorry to go off topic but i couldnt resist as I had exactly the same problem with my cg125 that baph described.
Baph if you ever get round to pulling the cg's engine apart i think you will find the little end bearing has disintegrated, the cg uses a nedle roller bearing for the little end and it appears it can break up resulting in the needles getting chewed up and sliced into little bits.
I found this out when my cg siezed up on me on the M4 about 10 miles from Bath at 3am, and i tell you its no fun when you pull the clutch in a hurry only to find the headlight goes out at the same time, huzzah for the generator powered headlight.
It took me about 12 hours to push the heap of crap the 10 miles to bath, stopping to sleep and get sunburnt buy the side of the road :)
I did rebuild the engine and it didnt cost too much but later the crank bearing failed which i suspect was due to me missing a bit of needle roller in the crank case (the crank bearing was subsequently replaced too) but to be fair I rode the bike from Bangor to Northampton with a knackerd crank bearing, and by god did it sound bad.
Just for good measure I also manage to fracture the piston (twice!) and snap the kickstart off as well as dropping it at least twice on ice.
I finally gave it away to a young kid who wanted a project and hes now using it to commute to work, it an L reg so its 13 years old but it was stood in a car port for 9 or 10 of those.
It may be a crap bike but it hard wearing LOL
Oh and you were never doing 70 on it, not unless they have tuned the engine alot in the last 10 years, mine would do about 55mph tops :)
sorry for the off topic.

I really cannot believe how inept some contributors to this forum are. How could anyone confuse oil pressure and level. The only way to check level is with the bike upright on a flat surface. It is less than a 1 minute job, so there is never any excuse for not giving the level a quick glance.
IMHO if the pressure light comes on, it is already too late. The pressure is required to generate a wedge to separate bearing surfaces and to drive the lubricant through the oil ways to the cams etc. If the pressure drops enough to light the warning light damage is already being done.
Things like a blocked filter can cause oil starvation, check the level and it is fine, but the pressure will be down etc. For the cost of a filter I see no reason not to change the filter at each oil change. Maybe because I learned to ride in an era when an engine seizure was a regular occurrence, you soon realised a quick check was preferable to being spat off.
It is a known fact, some SVs use oil. so why risk it.
:oops: i do check the oil ......but i thought the warning light was for low oil? i cant see the point in having a light come on after the damage is done???
but i have learnt somthing so im happy :oops:
Here we go again. Oil goes in 2 ways:
1) Slowly. There is pressure in the system (so the light's off) but the level is low meaning not enough oil is available at all parts. This is easily prevented by checking your oil level regularly, if it's cold, hot, cooling or whatever will make a difference but what's most important is that it's a regular check.
2) Quickly. If a sump plug comes out, or a pointy oil line to the oil cooler blows then no amount of morning checks will help as the level will go from perfect to empty in about 40 seconds or something helped by a good bit of pressure from the pump. This is why you have an oil light, at this point the engine still has a coating of oil, it will not disastrously explode 0.01 seconds after the light comes on but should be stopped as soon as physically possible.
Suzuki did not screw up, this is how all bike engines are. The majority of car engines are the same, although some new ones have nifty volume metres.

You should never ever run an engine low on oil, especially a bike engine.
The pistons and cylinder walls in modern engines are lubricated by oil splash caused by the crankshaft rotating in the oil pool. Low oil means no splash.
The oil also acts as a coolant in some of the hottest parts of the engine where water or air cannot be used.
In a bike the engine oil also protects the gearbox.
Don't scrimp on a couple of quid by not topping up your oil, you'll lose out in the end.

Unless like me, you have lowers and they block the sight glass :(
I think the main reason they recommend you run the engine for several minutes then leave it for several minutes is;
Warm engine for several minutes:
Warm oil is thinner, easier to see in the sight glass.
Let it sit for several minutes:
Allows the oil that has been splashed around time to settle back into the bottom of the engine/gearbox.
Just my £0.02
