One engine still smoking help

[Seastoke]

So my perkins 225 is still smoking ,i had a fuel leak on to the engine which i take was letting air in, i run it for say 6 hours like this and smoking badly. I cured the leak but the engine is still smoking ,will there be residue still in the engine or could it be some thing else ie injector ! if so i thought i could change one from the outher enine one by one or is this crazy thanks for help .roy

Running a smoking engine could terminate it, the likely cause is a hosing injector which could take the top clean if your piston , I'd be taking them out and having them tested straight away.

ok i live 100miles from boat so could i not take all 6 out and put the good ones in the smoking engine and if no smoke i can have the other ones checked ,or just have them checked ,thanks for reply

Yes you could , how many hours have engine done and how old are the engines?

259hr and about 10 yrs old

 

[Seastoke]

259hr and about 10 yrs old

And we think it is more a while or grey smoke

Would a leak off test show up a problem in this situation?

 

[oldgit]

Perkins manual states the injectors should be pulled after 2 years or 2000 hours.
Perhaps with 270 odd hours they have never been out.?
Simpler to just pull all six in one go and drop them round to your local non marine diesel shop and get the spray pattern checked.
Seems a lot of extra work to do a swap merely to confirm one or two are faulty.
A leaking injector could also seriously thin your lubricating oil,is the oil level remaining constant . ?

V low hrs!

Assume black smoke?

Your thinking 20 years of development on from when your Perkins were blueprints, probably 30!!

Common rail needs a leak off test when the rail pressure drops and it won't start.

As I've said take them out and get them tested before you need a new engine.
If I could post pics I'd send you a nice KAD 43 piston I've just replaced all because of failed tip.

....And if you have decided on getting a new engine, I bags the old one!

I take on board all advice so going to take out injectors and have tested but won't before a couple of weeks will keep u posted and thanks for advice ,it just seems strange that it started with a diesel leak now cured it's still there ,but aim a sparky

 

[Seastoke]

so i now realise the fuel leak has nothing to do with smoking engine ,i have taken the injectors to the local ,to me to be tested and serviced ,but there seems somthing elsr wrong as we are loosing coolant without a leak ,so now i need a workshop manual to carry on

Port side of the block, top, aft, there's a sandwich type oil cooler, known to suffer leaks. Tractor owners of Perkins Phaser change the gaskets regularly.

Do you have a boost gauge? What do they show?

Have you removed the blanket from the Turbo and checked the wastegate is free?

i dont think i have a boost gauge is this for the turbo ,but the springs on top of the head have slight rust which seems water has got in ,hence workshop manual we thought head gasget ,but i remember volvo paul comenting on somthing to do with cooling

seems everyone is going FUEL, but white smoke or steam? I ask this because we found after a long time investigating that the exhaust manifold had a leak, i.e the gases were escaping into the water cooled jacket which when cold pressurised the cooling system, but as the exhaust got hot the gap closed and the gases left through the elbow as expected, As we cooled down the water got into the exhaust pipe and filled up the turbo snail, which we found by accident. The manifold was removed and there was water inside the gas pipes, We had it sectioned and the engineer found what we suspected, the pipe was welded and the jacket refitted (welded) no more smoke no more coolant loss.

Hi what engine was this pls

Ford Sabre 180, 30 years old, still going strong, but the "ancillaries" are showing their age. Sorry I cannot comment on Perkins or the the marinising bits that go with them. It could be the same type of system? The jacket on ours is a stainless steel affair, but the innards are probably Ford cast iron?

Thanks slowly putting ideas what to try

 

[Seastoke]

so has anyone come across rust under the manifold ,coolant low and oil more
