should answer some questions. do you have a way of monitoring the oil temps and pressures?

Now my mind has been overloaded... Do I fit this thing or not?...if so what do I need ?? If not why on a long run pushing it along a bit does the buzzer of dooom sound and stop if I back off a bit???

You've clearly got a problem, and you need to diagnose it properly. Pressure & temp gauges, for sure. Cheap and easy would also be to just put a new high rev sender in, in case that's being paranoid.

Worn main bearings (and other internal wear) will allow the hot pressure to drop, especially with very hot (and therefore thinner) oil. When you look at an oil viscosity rating, the second figure is measured at 100degC. Poor quality oil will thin out rapidly as it gets above that temperature, good quality oil will remain more stable for longer.

No I don't .... Not really sure what to buy in the way of gauges that arn't crap!!

So do I fit gauges to tell me that the oils getting to hot or fit this cooler to stop it getting too hot.....

If your buzzer is going off for a real fault, an oil cooler won't fix it. If it's a faulty sender, the oil cooler won't fix it. It won't harm anything either, but if its going off after a long fast drive, something is up. Do you have fresh oil and filter fitted? Gauges help, but you have to know what is normal first. I had gauges and oil cooler fitted to my last engine, but to protect the engine, not hide a fault.
If i was you (i'm not ) i would replace the sender that causes the buzzer (cheap and easy) then if it still does it, fit oil temp and pressure gauges and record readings when it buzzes. If you fit an oil cooler, don't be tempted by cheap/small bore pipes, you need big bore, mine where 5/8" from memory with about an 1" outside diameter.

Is it getting too hot? <shrug> Or is your problem something else, and you're just not seeing the symptom (excessively low pressure) until the oil gets up to working temperature?

A "motorway run" in UK ambients really isn't overly demanding on an engine, even if you're sitting foot-flat all the time.

neil have you got pics of your setup? is it similar to the systems retro fitted to type 4 engines as much loved by the buses with attitude crew.

So I need to replace the oil and filter
The best oil is...?
The correct filter is...???
Replace the buzzer sender which is located..???
Fit oil press/temp gauges.. Type??
And as for the cooler...????

Kingprawn,

ello!! Don't be drawn into the oil debate....that will rumble on for ever on here. There are those that say semi-synthetic is fine, others only put mineral in. Me...I go with the old school and use mineral. But then I know nothing and go with those that have had a van for many years. The oil cooler debate also rumbles on....but how and where you drive can make a difference

right....in our family we have 3 vans running the 2.1 dj. All are LPG conversions, from the 1.9dg. Only 1 van has an oil cooler fitted, cos I bought a complete 2.1 with ancillaries....whereas the other two are exchange units....the engine place bolted all my 1.9 ancillaries to it. But... I don't live in the scottish highlands, the vans don't spend hours at 70mph (i tend to drive between 55-65 mph) on the motorway and the oil is changed regularly.

Also, no additional guages. Just regular oil changes with the correct grade mineral oil. I think its the 15w40 you want, but please check this.
Get a Mann oil filter.
Oil pressure buzzer....well, that would depend on the age of your van....my 1990 has two (a low and high) and my early 1983 has only the one. One is located down near the water pump pulley, the other between the push rods on the left hand side of the engine as you look at it from the engine bay. Have a look for telltale brown wires disappearing into the depths.

If I was you, I would start with an oil change and filter change.
If buzzer continues, change sensor(s)
then, if buzzer continues, you could try putting a slightly thicker viscosity oil in it....I think this applies to old and very tired engines. This may help the engine retain oil pressure....but again...it isn't fixing the problem...if you need a thicker grade oil to shut the buzzer up, your engine is worn. The thicker oil will help.....but eventually the buzzer will be back.
Once you have the engine performing without buzzer you can think about the oil cooler for that added protection, if you think that you need it...got it anyway so may as well fit it! I decided not to fit the coolers with the engine change a the fitters said it wasn't really necessary in uk ambient temperatures, the vans only do a few thousand a year, and I don't drive like I stole it!

If you haven't already got the haynes manual, I would grab one from ebay.

Good luck

Thanks very much for all that. My DJ has very low mileage as I had a new engine after the original went pop! I've had the van for nearly 10 years now and being in Cornwall use it as you do I expect with no real motorway use and do drive at the 50/70 mph mark. Guess I could change the oil more often!! Didn't realise that the 2.1 had a specific filter so I'll find a Mann one ..... Here goes .. I'd like to use the cooler but not sure about fitting it way up front , I hoped the being an extra I could put it somewhere in the engine bay, also it only came with a couple of meters of hose(large bore).....

[ermie571]

King,

err...if you replaced a 2.1 with a 2.1....chances are you have an oil cooler anyway....

I think for the part you are wanting to potentially put in, pictures would be useful

Also, the 2.1 doesn't have a specific filter.....its just that the Mann filters are known to be the best quality. So folk will recommend mann for 1.9 and 2.1

also....if its low mileage...was it a replacement engine? Worth talking to installers / suppliers about the buzzer?

Thanks Emma ... Yes I realise that I already have a cooler and I guess so did mr ETA-beta! And after reading syncrosimons piece about the potential problem with the 2.1s oil temp I saw this cooler and bought it....

Now my mind has been overloaded... Do I fit this thing or not?...if so what do I need ?? If not why on a long run pushing it along a bit does the buzzer of dooom sound and stop if I back off a bit???

If I were you I would have a cold and hot oil pressure check, that way you KNOW whether it's the engine.

[KINGPRAWN]

Sounds like a plan!!!!

that is the best thing that you can do at given you circumstance at the moment, a good healthy cold pressure at idle will be around the 4/4.5 bar mark. and once the engine is warm (and by warm i mean oil temp of 80c or above), at idle again should be 2bar or above. this should rise with the engine speed, clive goes buy the formular of from 2bar at idle, 1000rpm should see a rise of 1bar or there abouts.

but this is the beauty of having a couple of gauges as you have a real time view of whats going on inside your engine at any time, if you rely on the buzzer of doom it's normally too late.

as emma and adrian said the oil has a lot to do with this, and oil technology has moved on leaps and bounds in the past 20 years, dont fall in to the trap of thinking that you have to put a mineral oil in, there are plenty of suitable alternatives the far exceed the working requirements of the engine,
always buy a good quality filter.
