F6 Tyhpoon With 20k Rebuild?

[YLD-11Z]

Hi All

On the weekend I drove to Sydney for a holiday, halfway there I decided to give it a bit while passing my mate when all of a sudden the car backed off and the oil pressure gauge showed no oil pressure. I pulled over straight away, the oil and engine light came on and the car sounded like it was running on 5 cylinders. I ended up having to wait for a tow truck and it got taken to McCarther Ford. They rang me this morning saying that the oil pump blew and sent sh*t through the motor and it’s going to need a rebuild.

Firstly, is this possible considering its only done 20000kms?

Secondly, I was thinking of getting atomic performance to do a rebuild on it, are they any good or can anyone recommend something better?

Im not looking to spend alot of money but in saying that I dont want this problem to occur again so all opions welcome, thanks

siemens injectors

4 inch exhaust and cat

RAPID high flow v3 intercooler system

CV performance tune

If you've hit the limiter a few times it's likely that the pump gears have let go. For what it's gonna cost you to get a new F6 bottom end put in by ford, you might as well get an Atomic motor for a little extra with the addition of Kostecki Oil Pump Gears

Andrew, stock oil pump gears are quite brittle - was the car cold? Did you hit the limiter hard? These things aren't too un-common, but obviously aren't an everyday occurence.

Have you bounced the car off rev limiter previously? What sort of oil do you run?

Bad luck mate.

Like the guys have said, over revving will do it.

You can hit the limiter plenty of times and all is good, then one day, bang.

Atomic's are good, lots of guys making big power with them.

How do the gears shred when hitting the limiter? Is it only when bouncing on and off it or is it the same if your just hitting it once, like if you spin the wheels and it just flys up to the limiter then you back off????

It's the shock loading that does it, also the oil pump works basically in relation to RPM, so the higher rpm, the faster it pumps - the stock pump isn't really designed to flow oil at a rate over 6000rpm, some tuned cars have their limiters raised, this can cause problems too.

Yeah since getting the mods done, I have hit the rev limiter a number of times. Its had a fair flogging the last few months so I guess I should have expected it. The car was not cold, I was half way to Sydney. We pulled over for a stop and when we got going again I reved it out in every until 4th, moving up to 220kmh and 6000rpm then the car just back off and the oil light came on and the gauge showed no oil pressure so I pulled over straight away.

I have never hit the rev limiter in my ute but if it is a hard cut there would be big load on the gears then all of a sudden no load as the fuel or inition is cut and then a big load on the gears again when the revs drop and the engine kicks back into life. That on/off knock effect on the oil pump gears is what would do the damage.

that's the cause of the problem
