Kwik chip mechanical help needed!!!!

[Oliver3164]

I have a pain in the arse of a kwik chip euroline 160 with a 3 cylinder perkins diesel

 

It was overheating but running normal without any other problems bar the overheating, so after the usual problem of cleaning the rad I thought I would do the head gasket

 

Removed the head, new gasket, had head skimmed an tested for fractures put it back together.

 

Now it has started plooming black/grey smoke for the exhaust and running on after key has been turned off!

 

Had injectors reconned as thought it may be over fuelling, still has problem!

 

I'm assuming it's running on oil? Checked with perkins parts man which I got head gasket from and he's certain it's the correct one!

 

I'm stuck for ideas! Can anyone help?!

 

Thanks

it sounds like its running on its own oil be very careful as it may overspeed is the engine oil diluted with fuel also when its running see how much back pressure the engine has if its been cooked the piston and liners could be bolloxed when you have it running remove the air intake and be ready to choke it with a rag or a glove

also the previous experiences i have had with 3 cyl perkins haven't been good they were absolute poop from what i can remember

You dont need the help of Jez Smithers, the English rep for TS. An engine specialist is needed.

How do I see how much back pressure it has? What confusing me is it was running fine before I did the head no black smoke no running on? Surely if it's knacked pistons etc the problem would be occurring beforehand? Thanks

When the head as checked did the valve guides get checked out? One hasn't been broken and allowing oil into the cylinders?

look at the breather is there steam and fumes flying out of it usually with a fine spray of oil as well

what i do on the cummins engines is fit a t piece in the engine breather and connect one side to a manometer the other gets a 303" restriction in it and you run it at full load full throttle and read what it says then compare it to spec. is the engine turbo charged as the return could be blocked with carbon. there are so many different things it could be.and yes unless its something you've missed i would have expected the problem to be there before you touched it .

[Oliver3164]

No not a turbo and no nothing coming out of the breather pipe! Could the diesel pump timing be out even though it's not been touched?

[Breezeblock]

wouldn't think so, is this a pushrod engine with overhead valves

[Oliver3164]

Yes pushrods
