Hole in piston BF MKII UTE

[V8bushpig]

Hi fellow members,

 

I am in a spot of bother. I have just bought a second hand bf turbo ute and I have driven it 300kms and now it is blowing smoke out the exhaust and has a misfire on 6.

local mechanic looked at it and is nearly certain it's a hole in the piston.

whats the best option for me to do? 

Should I pull the head off and confirm it is and the. Look for a short motor to re-build it with or look for a exchange motor.

any advice would be much appreciated. 

Cheers alex.

If you want more power (not ridiculous), then replace with a FG F6 short from Ford.

 

If you want the same setup, then get a donor motor from a wreck. If you shop around, you can get them fairly cheap.

 

You'll want to confirm what the issue is, though. A compression test is a cheap to confirm damage.

USB boroacope,cheap as chips online jam that down the spark plug hole before condemning the motor.

Thanks fellas, the fella is doing a compression test tomorrow and also a bore scope and hopefully that will tell me what im up for.

is it possible that the turbo seals could have just let go and a coil pack at the same time causing the misfire?

as the oil on the dipstick is not milky and there is no bubbles coming through into the header tank?

 

If im up for a re-build who would you all recommend and what options would you recommend.

If not which wreckers seems to get the cheap motors? 

 

Thanks again

where are you located. 

 

either a motor from wreckers will get you back on your feet quick enough. straight swap. local mech can do it

I am goin gto pull he head off and see what I find and then go form there.

Has anyone installed a FPV trubo motor from a typhoon into a xr6 turbo ute before?

as I may have to buy a second hand motor and might aswell put a better one in then factory standard.

I want to use the ECU fropm the typhoon, does anyone know if this can be doen or will I have to re-learn all the computers to each other and also who can do that?

Cheers

So found out the side of the piston is missing on cylinder 6 and has also done slight damage to the bore. I will get some pictures later.

I can rebuild it myself I just need to get the maching costs quoted and go from there.

 

I did notice I couldnt find any of the missing pieces that have broken off the top of the piston, there isnt enough damage to the valves or cylinder for it to have been knocking around in the cylinder. there is no damage to the underside of the valves or head, the turbo looks ok and like nothing has gone through it.

 

Is it possible the old owner knew about it and removed the pieces or is it possible they could have melted?

 

Now I need to asses my options to either rebuild or get a second hand FPV f6 motor and drop it in and tune it up. Whats every ones thoughts

If you can rebuild it yourself that's the way I would go. Decent rods & pistons, a new ford timing chain set, good oil pump (atomic if its a manual) , service the head (maybe head studs depending on your goal) As reguards a s/h motor  how do you know your not buying your motor 400 km's ago? If you go a new fg short make sure you sort the dipstick out before you put your sump on.

It is likely that any debris has just been huffed out the exhaust and has taken up residence at the front of your cat. At any rate none of that matters now except maybe checking that the cat isn't partially blocked. If the turbine wheel is damaged you may not see it until you remove it from the housing.

 

If it was fine when you bought it and then broke a while later then I doubt the previous owner knew that the engine was going to break. They may or may not have known of an issue that could cause problems but that's neither here nor there.

 

Pistons don't crack for no reason and there are plenty of points of failure to cause a broken piston. The tune and fuel supply along with anything else will need checking to make sure that the new motor won't suffer the same fate.

why do you want the f6 turbo? not really an upgrade.
