Advice/Opinions Required

[Philious]

Well the other night I took my 6r out in the foul weather, the side roads were covered in ice and I managed to drop it at 2mph by touching the front brake.

Since then my oil pressure light has been glowing bright red and I've recorded a video of the bike idling to get your opinions.

The oil level is fine, its in need of a change but I had no problems before dropping it.

This is exactly the reason I wanted a shitty second bike for the winter

maybe the sensors got knackered,or the plug on its come loose from the fall

I checked the wiring for it, and its fine the bulb lights up when i earth the wire on the crank case, could be the sensor but the clackety sound makes me suspect something's not right.

Well I can hear a couple of things in that video.

Firstly sounds like the clutch basket is a little rattly, thats normal.

However is sounds like someone had dropped a bag of screws into the top end. I think its oil starvation to the head which is consistent with the light being on.

Its possible the drop has disturbed some crap in the oil lines.

What ever you do DON'T run the engine again.

I would do an oil and filter change before I did anything else. If the light hasn't gone out after that I would then do an oil pressure check. If that was okay, its possible it could be electrically related.

Worst thing you could have done, is what you have done. Ignored it and though 'it will be okay'. Anything to do with oil lights on the dash should not be ignored.

How long was it on it's side?
And was the engine still running, while it was so inclined?
The drop could have casued many maledies, from the simple, oil-pressure sensor cap coming off, but also possible that running at an unintended angle, the oil pimp pick'up was above the oil level, sucking air, not oil.
Turning the motor side on, also likely to have dislodged sediment from the bottom of the sump. That could have clogged the sump-strainer, and or relief by-pass valve.
Ultimately, its a piece of string, job...
But I'd start by changing the oil, and seeing what comes out.

It was on its side for a couple of seconds and I got it straight back up, it cut out when it went down.

The bike hasnt been ridden like this and it was only run for a few seconds tops.

The connector to the oil pressure switch is clean as is the switch, is there any easy way of taking the switch out and checking if its functioning properly?

I obviously wont be doing an oil change until i can confirm the switch is working/not working as these are prone to having the light come on after an oil/filter change.

I'm gonna get it picked up monday by the garage if theres no easy way of checking the pressure switch.

Might just need burping

[whitedevil]

Burping gets trapped air out the system, all you do is slightly loosen the oil filter, start the bike and as soon as oil pisses out the lose filter kill the engine and tighten up the filter.

Ok so this evening I hauled it into the downstairs hallway and dropped the oil out and apart from being dark rustic browny colour there was no metal flakes in the oil, no sparkles, no grey bits and nothing at the bottom of the oil container after emptying it.

The filter also shows no signs of metal.

Is there any easy way of getting to this filter inside the engine?

Or any ideas how easy/difficult the oil pump is to replace?

Sorry to bump this up again but I'm rather miffed.

So I had the guy from the garage pick my bike up monday, he checked the oil pump, took the sump off and checked all the oilways were clear.

He said there was a bit of swarf on the oil pressure relief valve, but couldn't give me a straight answer as to what caused it. But after reassembling the bike the oil light now goes straight back out again.

Struggling to understand why you are miffed?
New engines might contain small bits of metal but not what I would consider swarf. Either way, whatever crap is in the engine tends to either end up in the filter or sitting at the bottom of the sump. You dropped it and disturbed it causing it to move into the normal oil flow.

The pressure relief valve will circumvent the normal flow of oil, usually dumping straight back to the sump rather than feeding the head. Be grateful more damage hadn't been caused.

I can only speak from experience. Oil feed pressure to to the head is pretty much reliant on the fact that all is well. Reduce the pressure and the head suffers. I know for a fact that the bore size to the head of a CBR6 is 1mm. Honda messed up and fitted gaskets with 0.8mm feed hole. I have pictures to show what happened, unlubed alloy and hardened steel don't mix.

I agree with Chris, take a look inside the cam cover.
This is the damage from oil starvation on one of my bikes, can you see the swarf around the valves?

[0l0dom0l0]

Is it possible that the prv opened because the swarf jammed up the normal oil ways, or doesn't it work like that?

If the swarf was in the bottom of the sump, and got disturbed and thus sucked up through the oil ways when it was dropped blocking them and then the prv opened allowing the oil to circulate.

Or am I way off here lol? just trying to understand it all a bit better

[Ichy]

Absolutely right. Anything that causes the pressure to rise to a specified pressure will cause the valve to open. The OP mentioned that the mechanic said that there was swarf on the valve but the oilways were clear.

[0l0dom0l0]

Yeah exactly.

It just depends on the amount of swarf that came out the oil. Any swarf is bad news and suggests oil starvation to something.
