Info needed: Questions on a ford engine

[serge]

Hi JACQUES

I would take advantage of your good kowledge about engine to ask you an other question please.
I would like to inquiry about the link between the oil filter canister and the engine. At the rear (left side) of the engine we found two parts*: one is an electrical sensor (which aim is to indiquate the value of oil pressure when the engine is running) and the second is an outlet which is used to link a pipe to the upper inlet of the oil canister. (It's the ouput of the oil pump).

At the bottom of the oil canister there is an other outlet which should be used to return the oil to the engine with a second pipe and my problem is that there is no inlet for these pipe on the engine.

Having read some forum about these subject, I learned that these inlet should be below the exhaust pipe. I have clean out of paint the below of the engine but I have found no entry for the return of oil.

Please did you have an explanation about the behaviour.

Best regards Serge

into the oil pan, not the block.

Hi Serge,

As Harry pointed out the return line from the filter goes straight back into the oil pan.

There is an SAE inverted flare elbow at the forward end of the pan where the return line attaches. See photo.

Just looking at your photo it seems you have used copper tubing to the filter.
May I suggest you use steel Bundy tubing instead for two reasons:

Copper tubing can work harden and get brittle with vibration as can occur on any machinery part. If it fractures, there could be a catastrophic loss of oil pressure.

The other reason is that the fittings are designed for SAE inverted (double) flares. These are the type of flares required wherever there is liquid under pressure inside the tubes to ensure a leakproof seal. Steel lines with double flares are used throughout the braking system for this reason. Despite the appearance, all my tubing on the truck is steel Bundy tubing. Bundy tubing has a copper patina caused by the way it is made.

If you do not have the fitting on your oil pan, or a place for it, you may have a civilian car engine pan which did not usually have filters fitted.

If so, you may have to add a fitting or a doubler plate to the pan and drill and tap it for a 90 degree elbow.

Hope this is of some help.

Cheers,

Jacques, some of them returned oil to the oil filler housing (fuel pump mounted to it) I don't think it lasted long. Probably too much oil blown out when there was blow by.

Hi Lynn,

Spotted this on Gumtree Australia. Looks like the one you mentioned.

Cheers and a Merry Christmas from across the Ditch.

[Lynn Eades]

Yes Jacques, that would be it. Happy Christmas to you too. Stay safe and covid free.

Kind of a long shot but I don't suppose anyone would have a modern part number for the vacuum breaker fitting off the intake manifold.

Post-war engines had the Oil Return feed through a modified Dipstick boss. This type of boss is available as a new part to replace the older boss from retailers such as Mac's or Van Pelt Sales (I got the pic from their site). Saves having to drill and tap holes in an otherwise perfectly good pan.

Hi Lynn and Tony,

Didn't know they existed but that is a great item and a lot easier solution for Serge if required. Especially useful to a guy like me who hates extra holes where they never existed on a vehicle. I usually spend time filling in those type holes.

Cheers,
