MG TD TF 1500 - Fitting the Oil Pipes

I'm progressing with my TD engine reassembly and need help with fitting the oil pipes from the pump to the filter housing and block. Neither pipe fits well.

I recall when I received the car that the pipes held the original filter housing a bit akimbo so the pipes were bent sometime over the car's decades long storage. I forgot about it since I had so many other problems to correct.

The photo shows what I rediscovered when I tried to connect the pipes to the new spin off filter housing from Butch Taras.

To fit, for the pipe from the pump to meet the filter housing would need bent downward and the pipe end may need turned. The pipe from the block now strikes the block where it starts its outward curve and the filter end is too high to mate with the filter housing.

What to do? Can I apply heat and bend these pipes? Also, can I apply heat to the brass end pieces and rotate them to improve their fit?


Thanks,

The easiest solution is to buy flexible pipes or the original style from someone. But if that is not an option I would heat the pipes and bend them. You can heat the ends until the brazing melts rotate them and rebraze. But it appears from the photo that if you bend the pipes correctly the ends will line up without having to be rotated. In your photo it looks like if you rotate the filter housing CCW it would line up with the pipe from the block.

There's one on EBAY that might help for one of them. EBAY # 233190772760

Tim,

Thanks, I ran with your suggestion...I took the pipes to the vice and started bending them with a large crescent wrench. Back and forth to the engine until they fit well. I shaped the pipes and turned the end fittings until all mated easily. This repair was much easier than I expected.

Have you started the engine to check for oil leaks...it takes a VERY ...VERY small misalignment to end up with a leak.

Charlie.
The tubes are brass, so you should be able to heat and gently bend them. Ends are soldered in (not sure if it is silver solder or ?, so you can heat it and turn then tub at the fitting.

I have a spare set if you happen to damage it or I can send it to you to check it against yours to get it bent correctly.

It isn't unusual to have to slightly bend them when changing filter types. I make small bends by hand. Try not to bend back and forth, as this will harden the pipe and risk a future fracture.

Charlie, well done.

Looking good Charlie--
Just a little word of warning--
With this style of filter adapter the oil flows through the filter in a reverse direction to normal,-Not sure if you were aware of that--
When selecting a spin-on for it you 'have to' make sure there isn't a one way check valve built into the filter

Good looking engine by the way, impressed with the wired gallery bungs, nice touch

To correct, or add to that, not all these adapters are the same--some do the reverse flow thing and some don't--ie, some are cross drilled inside,others not

Normal flow for a filter is in the outside holes and out the centre
Your adapter has the oil going in the centre at the top so it will depend on what is happening inside the adapter as to which way the oil will flow through the filter

Easy to check, remove the top banjo bolt and if you have an air supply blow in the banjo hole and have a feel underneath to see if the air comes from the outer hole (correct) or from the centre stub-----hopefully it will come out the outer hole

Willy, I just had a mental picture of Charlie covered in oil. :-)

go with the flexible pipes,Marino used to make them up. Mine have been on for over 20 years and they are still holding up. I have seen the copper ones break to often. When they do, boom, you is out of oil right now.

The adapter that Charlie is using has the oil flowing the correct direction. The oil coming in at the top goes thru a hole drilled at an angle to let the oil flow into the filter around the outside. The output flows from the center to the outlet on the side.

Cheers Butch
I was just a bit concerned as I had heard of an adapter that runs the oil backwards through the filter ,making filter choice very important
Why they would do that, I don't know--easy to make i guess---but just waiting for 'THE' mistake to happen------then no oil pressure
But if Charlie's is definately cross drilled all will be well--

Thanks Willy. I make them the best I can.

Thanks for all the helpful comments!

At Butch's suggestion, I annealed the pipes. I was able to get within 1/4 inch of the ends without distrubing flux. If I encounter leaks, I may promptly go the the flexible pipes.
