Have I done the head gasket

<< < (4/6) > >>

Hi

Last post was not quite correct. I have modified it!

Yes it was hydraulic locked. I came to start it again to charge the battery up a bit after it had stood for 3 days (for when I came to re-start it after I'd done the head gasket) and it turned a quarter of a turn and locked solid.

When I think about it you are indeed correct for it to have a hydraulic lock on cylinder 3 then the valves must have been closed for the compression.

Trouble is cylinder 3 is the one that is at the top and cylinder 2 is not full of water or oil and its too low in the bore to have locked up.

My worry is that its actually the turbo that is the problem and that its chucked all this oil into the cylinder.

Still its not a big job and its going to be better for having had a head gasket but I really should check the intercooler I suppose to see if its full of engine oil?

Cheers

Yes, turbo good point.  If the turbo had failed though I'd expect you to be getting a runaway engine (runs on it' sown oil, then explodes) rather than this, somehow the oil is only running into the engine after it has stopped :-k

Easy to tell, pull the top intercooler hose off and check for oil.  With the engine running you will soon find outif any oil is being blown through the intercooler.

top pipe has a little heavy oil in it but nothing more than you would expect and certainly not any engine oil!

Suppose I can out the turbo idea to bed.

Only other things I guess could be a cracked head or block?

May get the head pressure tested to be on the safe side.

if it still isn't right when i put it together then I may well be found crying in my beer!

Range Rover Blues:
Just noticed it#s a 200TDi too, I know how much a new head will cost :'(

On the plus side, I strongly suspect it won't be a leaking head, there isn't any oil under pressure anywhere near No.3 cylinder AFAIK.

Have you noticed any oily deposits on the back of No.3 inlet valve or in the port, or inside the plenum come to that?

Hi

Okay here is the news...

I got the head pressure tested and it was fine.

I had it skimmed (did not really need it but I insisted!).

I out it all back together and its the same as before.

Still getting massive clouds of blue/white smoke under load when its cold.

Its fine when its warmed up.

So I know its not the head or the head gasket.

I don't think its the turbo as its not running on and there is no sign of engine oil in the inlet (just some small bits of heavy oil).

The injectors on cylinders 2 and 3 and the glow plugs were covered in engine oil when I removed them.

So anyone got any suggestions?

I guess a leak down test?

I fear that its maybe curtains for this engine.

The bores did not look worn at all on it and its only done 123K which is not excessive for one of these engines.

I dunno what to do next. Its got me stumped it has :-(
