weil mclain oil boiler whirling noise

Good Morning folks-
I have the above boiler it is a WGO-4
It has been making a loud whirring or whirling noise after about 5 minutes of running. Lastnight I noticed the noise went away after it was running for a bit and then returned.
A new pump and squirrel cage was put in Sat. the person doing the work suspected those two might be the cause.
The furnace was new to us and I had to clean it up as it was prety bad-clogged to the point where light did not come through from the fire box.
The flu was not as bad, but enough so that it took about 25 minutes to clean.
A few other notes on this-
I cleaned it because it needed to be done, but also the service tech thought this was then the issue-
since I cleaned it the air controller on the flue flaps non stop.
From the fire box I can see the light of the flames on the bottom (no flame-the light reflecting off of the basement floor.slab)
the sound seems to get louder as the boiler heats up and the second floor is not nearly as warm as the first floor.
here you have it-any ideas??
Thanks
Bob

Beckett oil burner, right?

Did anyone remove the cover on the oil pump and replace the filter screen inside? I bet it's plugged up...

Wait... you said the pump was replaced... hmmmmm...
I dunno! That woulda been my first choice. I don't have a second one yet.

HUH? No, this don't sound right at all... you mean you can see the light from the flame UNDER the boiler?

since I cleaned it the air controller on the flue flaps non stop.
By air controller, you mean the 'barometric damper', the part with the flapper and the weight on it?

When you say it 'flaps', you mean it just wiggles around a little bit, or does it actually swing open and closed a lot?

If the latter, I would think you have an unstable flame... pulsating...

Did the technician replace the nozzle, and clean/adjust/gap the electrodes?

Did he do any combustion testing?

DO YOU HAVE CO DETECTORS IN THE HOME?

I meant flapping open and closed-the dampener.
The flame light is from the loss of a part of the door gasket.
When I say pump-I mean the larger round motor to the right side of the firing gun.
I do not have a CO Det. It is a pretty old draty house-The nozzle was replaced but with a .85-60B not the 1.25 80B
Should I put the nozzle in (I have the right one because I thought I should get it...
The tech. is coming Sat to fix the gasket.
I am worried about the noise though-where is the screen?
Thanks
Bob

First off, WHAT BURNER is installed? is it a Weil-McLain? or is it a Beckett, or what?

The OIL PUMP is on the left side... probably black, the oil lines go into it.

Another thing that must be checked is the FUEL PUMP PRESSURE.

The oil filter has been changed, correct?

The nozzle being changed that far is probably part of the problem with the unstable flame. You really shouldn't try to 'downfire' the burner that far. And the 'pattern' 60 vs. 80 is probably not advisable either.

The gasket missing is a problem with combustion also, you can't have 'air leaks' like that.

Are you sure you've got the right tech working on this?

I ask again, DID HE DO ANY COMBUSTION TESTING?

The pump screen has been changed
The motor is a Beckett and is was checked and the squirrel cage changed
The filter at the tank was changed
I also put the correct nozzle- 1.20 80B
The fire box, boiler piped and flu cleaed.
It is a weil mclain boiler
He did not do a combustion test.
Since I replaced the nozzle, filter and the screen the flu dampener is no longer flapping however, the original noise is there!!! a whirling sound!

Is the gasket still damaged? I wonder if you could be hearing air getting sucked in through that opening?

I am very puzzled though.

Yes, please do let us know if the gasket fixes the noise!

And hopefully your technician will be able to test the combustion when it's all fixed up? While some of the old pros can get pretty close setting a flame up by eye, it still should be done with proper instruments.

Well-
We were all wrong on this-there was a clog in the boiler!
Sounds perfect now!

How on earth did you get a clog in the boiler?

What was done to 'fix' the problem?

Did he do any combustion testing?

I can only guess. It was a used unit and for all I know a kid threw a old rag in it.
It has been going though for a couple of years-so, it might be the hard, well water?? We have a sed. filt. on the house line...

I was having him put an indirect. tank on and after it was drained it worked perfectly-so, there is an assumption that there was a clog.
No, he did not do a test.
