Turbo-disaster / Part two

[LennyK]

Sooooo… after a couple weeks of constant shifts and miserable weather am back into it today.




128826
Just a little oil*** in the inlet pipe leading to the inter-cooler




128827
Have pressure tested the system from the turbo side to the inlet manifold side and it holds 14lbs/in2 no problems and will repeat when it goes back together so that there should be no problems causing over spooling etc.


Then pulled the inter-cooler and pipework out and flushed it out; all clean and no nasty bits from the disintegrating turbo.


[bigsad]Bad stuff….inlet manifold is full of sludge and exhaust manifold is full of oil, so quite a lot of oil went through the engine which might have accounted for the engine knock heard just before shutdown. Anyone have any thoughts???

I presume your hope is that the knocking caused by the oil hydraulicing the cylinders is better than a big end knock caused by no oil pressure. (by the way they both sound very different so this should be a hint)
Maybe it is but i would doubt it, diesel engines usually bend rods in this situation.
Get all the oil you can out of it put your new turbo on it fire it up and see what you have got
A cylinder balance check might show a bent rod and run big ends will be obvious by the noise
Oh and it will smoke badly at first

I still say get a second hand engine from Dazza it will likely be less pain in the long run but you might have been lucky you never know

Before i would fire it up id be cranking over by hand .
If there is a hint of strong resistance id be pulling the glow plugs for starters and see if any oil is in the bores and at worse the injectors [bighmmm]
Doing this with the inj or glow plug`s out should expel anything in the bore`s and save on bent rod`s[thumbsupbig]
The last thing you want is more damage on start up[wink11]

No...The hope is, the two knocks I heard B4 shutting down were due to low oil pressure but at the moment I,m not holding out much hope.

As Lenny isn't my daily and I've never had a diseaseal an engine rebuild will be a learning experience although I was hoping to see out his first summer before working on him.

Working towards this now :bangin:

Turning into a learning experience!!!!….and not necessarily a good one either.

Lenny was bought off of a “MECHANIC” in April with the head having been overhauled in an engine out check that included new clutch etc.

Few weeks later the turbo blows in a big way (bushes totally stuffed)

While pulling parts off today I note that the filter has a date written on the back of it…from when it was last changed I presume which reads 14/11/16 mmmmm. Didn’t want to change that then during the overhaul then. :censored:

Pulling of the inlet manifold I find two of the bolts are stripped…starting to get a little miffed about now.

Not what I really wanted to see....

Really REALLY hating the guy who didn't put a pre-heat in number one cylinder about now. :mad:
