My 2012 XF Portfolio has been a totally trouble free car with 56K miles. With that 5L V8 with Mina's exhaust, I absolutely love the car.
Given the resale value of these cars, it makes sense to keep it. As far as I know, some of the major problem areas have been taken care of including the water pump, coolant manifold pipe etc .

Looking for inputs from you all from a preventive maintenance stand point so that I can minimize the chances of a huge repair bill

- 2012 XF Portfolio with 56K miles. Was a certified pre owned car when I bought it 3 years back

- Changed the following at 38K in 2016 August. Water pump C2Z31587, Tube C2Z18658, O-Ring AJ811539, Pipe Outlet AJ89664, Hose C2Z4547

- 45k Service done. Air filters, Brake pads etc changed

- Regular oil change every 5k miles

Pl let me know your thoughts and comments

 

Good . it will be needing a transmission fluid and filter change before 60k also think of changing the supercharged oil it will have evaporated some and the remaining oil will be a dark brown foul smelling gunk car will thank you

 

>changing the supercharged oil
Can anyone explain how that is done? Just curious at this point...

You missed the crossover pipe in the rear of the engine. That's a ticking time bomb and you're basically doing a repeat of the work you did before to get to it. Much better to do ALL the plastic at one time instead of repeating a horrible job every time a new piece fails.

 

as a Portfolio car, you dont have a supercharger, so you dont need to worry about that.
as a V8, you should make sure the timing chain and tensioner are in good working order

 

Oh, yeah, timing chains. Basically the death of the car considering how difficult and expensive it is to repair, and the repair can easily be a failed one that means doing it again or replacing the engine.

 

Any one knows the part number for the cross over pipe? I can double check with the dealership whether they changed it

 

Brake fluid? Supposed to be done every 2 years up to 3 in a dry climate. Wish I had a dollar for every brake master cylinder, caliper, wheel cylinder, clutch master cylinder, etc. that I've tossed in the scrap metal bin because it was too far gone to rebuild....

I'd also get under it and check all the suspension links, ball joints, etc. I know I've got a couple of rubber boots split in the rear and I'm coming up on 47K. They seem to naturally rest at a pretty extreme angle which I'm sure is pretty stressful on the rubber. Ordered new parts out of England (SNG Barratt) a few months back and just haven't gotten around to installing yet.

I plan to do the rear crossover pipe before too long but I'm hoping to go at least another year without it forcing that issue. That's not a one-weekend job and I've got about 500 weekends worth of other car projects lined up ahead of it not to mention several years worth of home improvement projects. If it happens to need doing in the next year, I'm probably going to have to pay somebody to do it. Unfortunately or fortunately depending on how well the latest version holds up, the water pump has already been done multiple times. And from all I've read about the timing chain guides on the forum, it sounds like we shouldn't need those until about 85K at the earliest. That will be fine as I think I'll be ready for a newer daily driver by 2025.
