Mk7 ford transit 2.4tdci

[Boonjason]

Can anyone confirm if the engine drops 2 piston ring the engine will not start and the oil light would be on cause there would not have any oil presure only asking as someone took there truck to a garage theve told I'm is fuel pump had gone that cost £675 then he told I'm that is injectors where no good cost £900 now he's been told it's dropped a couple of piston rings it starts up but it doesn't sound good like the timing is out but I don't want to touch it in case I end up getting the blame and end up in court thanks for any advice just trying to help this bloke out

Oil pressure is separate from the pistons, so unless it has no oil in there shouldn't be a problem there, should still make pressure to turn the light off. I know that the Transit engines are prone for cracking pistons, this is due to faulty injectors.

Like anything it could have major problems, I personally wouldn't touch someone else's work, as we live in a blame culture now, last person to touch fault.

Thanks for the reply and yes your right about touching someone else's work the truck starts but breathing heavy but it isn't smoking and I thought if it had dropped a piston it would be burning oil and smoking badly and sounds like the timing is wrong as it will not rev up and sounds ruff and other trucks that have dropped a piston normally smoke badly and I'm thinking when they fitted the fuel pump they've not set the timing up corectly

Its just a high pressure pump on a 2.4 tdci, so the pump doesn't really need timing up...

As motorman116 said, the fuel pumps on the Mk7 TDCi's don not need timing and they rarely fail. If the cam timing was not correct on the Mk7, it will not start at all as they need cam/crank sync to start.

Oil pressure has nothing to do with piston rings. 2.4's are not usually prone to burning pistons, this is more common on the 2.2.

What work was actually done to it..?? If the pump and injectors were replaced, were the injectors coded into the PCM and all the learns done. If it is breathing heavy, the copper injector sealing washers are probably not well.

Hi knobby1 mate the engine is no good starting from cold sounds very rough then soon as it gets hot it cuts out and locks up and struggles to turn over all the injector seals have been checked and are all good someone says it may of dropped a couple of rings so just got a replacement engine to go in it and don't fancy a cheap recon engine with cheap sh*t parts that's going last 5 minutes

The basic Puma engine on these are quite robust, the rings rarely fail...it's usually the accessories attached to them which fail first. Sounds like your starter may not be well. Poor/hard to start when cold is often due to air ingress, the fuel siphons back to tank when stood for a while, then it takes quite a while for the fuel to be drawn back up from the tank when starting from cold, live data will show any issues with fuel pressure etc. Cutting out when hot is sometimes a poorly SCV/PRV. Hot starting issues can often be a poor starter. But there are a number of things which can also cause these symptoms.

Let us know how you get on.

Hi knobby1 mate it's had a brand new starter motor new batterys it starts when cold won't tick over right and cuts out when hot and the engine struggles to turn over after that so the owner looking for another engine as he doesn't want spend anymore money on that engine and I don't want get the blame and end up in court mate thanks for the info though much appreciated thank you mate

EGR valve can also cause a lot of running/starting issues....Again, live data can help diagnose things.

Probably wrong but I got advice on probably the pump gone wrong after I replaced SCV and PRV and had similar symptoms, although I did have massive diesel knock on cold start and white/blue smoke when cold and it cut out when hot. No fault codes or lights. Fuel pressure was insanely high. Had no idea the ecu could go that wrong or seemingly adjust to failing components without so much as a fault code or a warning light. All got solved. What does engine locks mean? How long after stalling warm will the engine restart and does it start from cold fine?

When you replaced the SCV and PRV, were the learns done..??

Not completely sure mate. They said fuel pressure was off the scale and adjusted it, are a good injection specialist so presume they did they learns as I wrote down what I'd done and hadn't but didn't ask. Can you relearn a learn at any time to be sure? Would have done it myself, but was convinced it was f@@ked, so didn't bother. Turns out in the end I'd 98% fixed it.

"They said fuel pressure was off the scale and adjusted it" ..?? It's not adjustable as such, it's all controlled by the PCM & SCV when the learns are done. If the pressure was as they say.... "off the scale" it would have blown the PRV.

You can do the learns at any time.

Hi knobby1 I told the bloke I wasn't happy to mess with it as he was just after someone to blame and started saying I'll see you in court so I didn't touch it and sent im packing on the back of a recovery truck
