2010 MK7 2.2 ENGINE P8FA (PIC HEAVY)

[M88NY]

ive done many and they all like that even the 2.4 do it as well

the only theory i have is lack of oil/low oil pressure due to the poor desgin of the oil pump

This making sway more to getting rid what happened to hassle free motoring. God knows what the inside of mine looks like ..
Think I'll try the pcm again and have a serious think on whether or not to get rid

Was thinking of fitting a brand new water pump to this engine.

But then bagged this complete assembly from Ebay.
Power steering pump with water pump. Removed from a 2014 Transit Custom - Bargain price of £42



Yes it's the same fitted to mk7 2.2

All good stuff Paul

Please don't forget to take the old pump apart

BHM

Oil pumps fitted to mk7's are the same used on Transit mk6 - Part no 1S7Q-6600-ROZEA
Stripped down old oil pump today. Here is the outcome.

Black arrow is oil flow path





Gear shows signs of wear on teeth.





Pump housing has excessive wear & scoring.







Relief valve worn on one side.



Relief valve bore also worn & pitted.





Conclusion

No pump specs available - Unable to determine manufacturing defect within pump itself

Excessive wear due to ether: -

Not serviced when due.
Wrong grade / type of oil used
Cheap/ poor quality oil used.
Oil contamination - diesel/coolant.
High mileage (Not the case for this engine)

Many thx Paul,
can you determine if there is any wear on the gear shaft/bearings and associated housing bearings?
One image seems to show a simple aluminium bearing for one shaft and the other shaft having some
sort of bearing insert.

Looks a bit like its been pumping some sort of solids for a while

Glad I change my oil every 10K

There are no separate bearings. Gearhshafts rely on oil pressure just like camshafts do.
There is some wear present on them. Without pump specs can't say if excessive or not.
Pump manufacturer is Pierburg.

Hi there,I'm in the process of building one of these engines atm,I've built 8 of these previously For a hire company I work for and never changed the main bearing and big end bearing cap bolts but have read that these bolts are tty/stretch bolts,do you guys replace these or reuse the original ones because I can't find a supplier for the big end bolts anywhere in UK ?.......thanks guys

Same here. I've used old ones.

There's nothing in Ford specs regarding replacement of mains & BE bearing cap bolts.
Although Ford specs to state....

Discard & fit new -

Cylinder head bolts.
Rear crankshaft seal bolts.
Valve cover studs.
Crankshaft pulley bolts can only be used 3 times, After which fit new ones.
Injector clamp bolts

Cheers guys.....Paul it says on Autodata that you should renew main and big end bolts that's where I got it from....many thanks
