Oil Buzzer after changing sump 😰

August 03, 2025, 09:06:54 AM

Hi All,
I went to replace my leaky sump gasket and noticed the sum had lots of fairly large bits of god knows what in the bottom and was really rough itself, so decided to change it for a new one from Heritage.
It took a few days to arrive which meant the car was 'sumpless' for almost a week in the garage but I thought, as I would be putting plenty of oil in anyway, this wouldn't be too much of an issue.

After replacing it all (and filling with oil of course) it was really noisy when started. I though id leave it idling to get the oil distributed and then a gentle drive of about 200m down the road and back.

When I got back the oil buzzer came on so I went to put it back in the garage to inslect and the engine cut out.

I haven't started it again since as Im scared somethings really badly wrong. Please can someone give me a little advice on what to do next?

Really appreciate the help. Thanks in advance ☺️

Ok, few things could have set off the oil buzzer;
You could have a blocked pickup, did you inspect it when the sump was off?
You could have not put enough oil in/some has leaked back out, that will also set off the oil buzzer.
You could have used the incorrect weight oil and put too thin in, again causing a drop in pressure.
Unfortunately, the oil pickup could also have collapsed (the god knows what you described in your oil).
When you reassembled the sump, did you inspect the crank? did you see a build up of any dust or debris where you'd left it open?

If I were you, I'd check the level of the oil, then see if you can turn the engine by hand.
This will give you an idea of the condition of the engine and what has happened to it.
If there's enough in there and the engine turns over by hand, you're safe to attempt a restart,
Then pull off the dizzy king lead (so it won't start) and crank it till the oil pressure light goes out.
This will ensure oil has gotten around the engine again and it'll be safe to attempt another start.
Keep your eye on the oil pressure light and oil temp (if you can).

If you can't turn it over by hand, then unfortunately, something bad has happened and the engine has picked up.
If the oil pressure light doesn't go out when cranking for 30-50 secs, you're not getting oil everywhere, stop cranking, drop the oil sump back off and inspect the oil that comes out and the oil pickup on the oil pump. You might get away with fitting a new pump and trying again.

Was the stuff in there hard black plastic bits? If so probably the baffle, I grounded mine one day and dinged the sump it broke into pieces and some got sucked in the pump pick up.

Thanks both really appreciate the reply and the help.
@Monkey the engine has been solid for the last 5 years but hardly gets used nowadays tbh.
I'll go through the steps and update.
In the meantime I've created a link to the pictures I took of the stuff in the Sump and from underneath which may give a bit more context.

Those red bits look like the dipstick tube red bit has broken before and gone into the sump, probably been replaced.

Agreed, I can't think of any other red plastic that gets anywhere near getting that close to the oil supply.
Can't get my head around what that collet it though, was it in the sump? Looks like one of those collets that go around bolts in modern engine rocker gaskets.

Either way, that oil doesn't appear glittery, so that's a big positive.
You could just have a dead oil pump.

The engine is turning freely with little resistance which is great news.

Yeh @t2000 its weird. The little.metal ring was in there too which was more concerning but a quick goole and it looks like a rocker cover spacer maybe? Apparently does happen if someone has replaced the rocker cover before and dropped one in 😫

Going to try and do what you said @monkey and maybe put more oil in and try it without the dizzy lead attached so it wont start and see if that works.

I suppose its been left to drip dry for a few days and as such the level needs to be 'too high' on the dipstick markers for it to pick up and recirculate right?

Good to hear the engine is still spinning, fingers crossed, you may get away with it.
Must admit, I keep coming back every couple of days just to see how you're getting on!

Thinking about it, it might be that there was just an air lock around the oil pump and it didn't pick any up.
I wouldn't try and overfill the engine, just fill it up to full, pull the king lead and then turn it over for a minute.
The slower speed of the pump should pick the oil up and send it around everywhere, once you see the oil light go out, you know you have pressure. Give it a minute or two and look at the oil level again (you may need a small amount more), then replace the lead and attempt a restart.

So ive just done what you said and the engine is truning over but then slows down as if there is resistance so i darent try much longer.

I found a video by ChrisFix on youtube which suggested spraying some 'fogging oil' into the spark plug slots to lubricate the cylinders? Not sure if this is a possibility maybe?

Would another idea be that maybe the system has drained completely while it was stood and when I turned it over fist time it siphoned out the last bit of oil from the system and caused an air block maybe?

Going to try and fill the oil filter up with oil and crank it without the dizzy king lead on to see if it gets it circulating.
Clutching at straws here 😫

I do really like those Chris Fix videos, shame he's slowed down producing them.

So how slow was the cranking getting?
As oil pressure builds up, you will notice it slow a little, also, your battery is probably starting to get tired (unless you're charging it between fault finding sessions).
One thing you didn't mention, did the oil light go out?
If it goes out, you've got good oil pressure again and can attempt a start.

Another thing you could try is to take out all four spark plugs, this will remove the resistance caused by the engines compression, it should spin pretty quickly then and get oil everywhere it needs to go.

So ive taken off the sump to inspect and it wll looks the same but what was a little strange was that when I tapped the grill inside it blipped a little and then leaked more oil so thinking maybe an air block of somesort?

Ps the cranking slows as if its struggling due to friction/resistance if that makes sense so decided to inspect.
