Thread: TD5 External Oil Filter Installation

I'm sorry I can't help on where to tap into, but if you're serious about extending oil drains then really watch your UOA's carefully and be ready to do a dump and refill if anything is remotely out.
Really watch your Fe, K, Na, Si, TBN, TAN and soot levels.

Also remember your Fe might be ok'ish but your PQ Index could be through the roof when a conponent fail's as the chunks are big.

I think you missed some more letter`s out of the alphabet rick

He missed out Cr, Mo, Al, Ni Cu, Bi, Pb, all could maybe be found in oil. No chance of He, Xe, Ar, Po, U, Pu.

Why add another external oil filter? 2 not enough?

.. each to their own I guess .. but Ricks comment should be taken more seriously than just a passing glance.
Oil will look nice and clean at 150K klms, but it's ability to lubricate will be severely diminished long before that.

I remember my dad use one of those external filter contraptions on his '67 Cadillac and basically killed it after a couple of years.
Saved himself about 4 oil changes(in todays money that'd be around $200-300 or so) ... but cost him in a few K's in an engine rebuild instead!

Again I am not trying to convince anyone however my cousin ran his taxi in Toowoomba on the same 4 litres of oil for 1.4 million km in the early 80's using one of these filters, it was a petrol holden red motor though. And I fitted one to my fathers 83 Fairmount Gear and we changed the oil once after 10 years before selling the car 10 years after that. We always took oil samples and had them analyzed by a professional lab to monitor the condition of the oil regularly. I can't say what caused your father's engine to fail, it could be many things, silica is the biggest engine killer and is usually due to a problem in your air intake - regular oil sampling will provide preventative evidence of such problems long before critical damage is done. Whatever the cause of early engine failure was sorry you had a bad experience with your external filter, I think there is mountains of scientific evidence that proves beyond any doubt external oil filters work.

As for what Rick said above, the quality of the oil can easily be confirmed with regular samples and lab reports.

Does anyone know if the TD5 has an existing port in the block that could be used for the return line? Is it possible to drill and tap the gallery on the spin on filter mount? Or perhaps the return on the centrifugal filter gallery?

This is great information Rick thank you, looks like you really know your lab results

Hi,

I hear what your saying but yes according to the manufacture, I asked them the same questions personally and the said it just filters a small portion of oil at a time but over 1000's of km it cleans the whole system.

How much was the filter kit?

I' not sure if tapping the oil filler cap is a good idea. You'd be introducing a large volume of oil, are the return galleries up to this?
