Timing chain oiler

[simonandjuliet]

As Most Fulvia owners know, there is an oiler pipe/nozzle just above the crankshaft that often gets broken when a timing chain is changed and can lead to low oil pressure

I am putting a spare HF engine together and no surprise, the oiler has been snapped off (and braised up and re-drilled).

My question/request is if anyone has any "tricks of the trade" for removing the old stump, without damaging the crankcase. I know that the original flange was pressed over the oiler after fitting. I am sure that I can slowly cut away the flange, but it is a bit uncouth !

Anyone tried a very small hole-saw for example?

Thanks

As requested ..... although you know what it looks like , Tim !!

Alongside the braised oiler is a spare, s/h, original

Thanks again

Drill a hole in the centre, then use a stud extractor?

[simonandjuliet]

Thanks Richard, once the flange has been removed, I think that is a good solution, it is how best to remove  the flange

Maybe this photo explains better ( been playing with photoshop for the first time !)

Put a self tapping screw in and use a small slide hammer/bearing puller, or small pry bars? I have removed ring dowels by inserting an appropriate size thread tap. perhaps if you cut it flush to the block?

Put a self tapping screw in and leave it there.  The oiler is one of Lancia's overrefinements and deleting it makes little or no difference to the life of the chain.

And gives potential good oil pressure elsewhere (taking into account the pressure release valve) On an assembled engine the self tapping screw can be fitted by removing the crankshaft pulley.

My 2p worth
Don't need the oiler nozzle and the idea of brazing over a broken one and drilling a wee hole is brilliant
Reason for my view is that my last Fulvia decided to have the nozzle break off for no reason while sat at traffic lights
Said broken nozzle then jammed the lower chain between sprocket and the chain and completely immobilized the car 
Alistair Cunningham (many many thanks) towed me from centre of Edinburgh and we fixed it however haven't forgot

Bought my Fulvia Zagato in 1986 with a broken oil nozzle and excellent oil pressure ever since, Andrea

One thing that transformed my oil pressure was a new pressure gauge sender(!)

[SJWhite]

Said Alistair Cunningham had Black Tape over the lowest part of the Oil Pressure Gauge
So he couldn't see the pressure going to 'Zero'
Never had any problems

Surely the oiler nozzle feeds oil to the skew gears on the crankshaft, which drives the oil pump / fuel pump cross shaft.  Nothing to do with lubricating the chain.

I thought I would resurrect this thread as I am replacing this oil nozzle in a couple of crank cases.

The removal process is fairly straight forward but because of the risk of swarf getting into the oil ways it is recommended not to do this in situ but when the crank case is dismantled so the oil ways can be thoroughly cleaned out afterward. Also to fit the new nozzle correctly the crank case needs to be heated up to around 150C (difficult to put the car in an oven!).

The process was written up in Neale Sheppard's article in VL on Fulvia Oil Pressure (Can't remember which VL it was published in).

Essentially you drill a 5mm hole into the centre of the remains and tap an M6 thread. Then with some M6 studding inserted the remains of the oiler can be pulled out breaking cleanly as you see in the photos the swaging of the original installation. The new nozzle is an interference fit so heat the crank case up to 150C in an oven and push in the cold oiler home into the crank case with some loctite bearing fit.

Note the oiler supplied by Omicron is more of a push fit so a loctite bearing fit adhesive is required. I also applied some hi performance Devcon aluminium loaded epoxy to fill the recess.
