Can't believe what I'm hearing.
Feel for you mate.
Like the Jamaicans say.
Let get together and feel alright.

Mate I can't believe what I just read....

snip/.....Might even be able to make this one,,, if you can PM the address,

Mate. Don't get us all excited for the, erm third? Time. I think we are just going to have to drug you "BA Baracus" style and just bring you over....
Lol.

I can't find the other thread about your engine problems so I'll put my thoughts here, it's been said it was possibly a hydraulic lock but I don't think so because it either
A: would have been locked up and wouldn't start or
B: locked up straight after starting, not 20 minutes down the road. The other thought I had is in the old days before intercoolers & Computerised truck engines if the turbo shit itself it would pump oil through the engine and King rev to the point where you couldn't stop it apart from stalling the engine . I realise Andys engine is intercooled but I would've thought if enough oil passed through the intercooler to enter the combustion chamber it would burn rather than accumulate and hydraulic lock . I could be wrong on all accounts it was just a thought I had .

Hey mate, it is certainly possible and has happened before where a hydro lock doesn't necessarily lock up from the liquid when it enters, especially in small amounts like in my situation.

It is possible that the oil has entered the engine causing number two to restrict and cause the conrod to bend (Wouldn't know yourself this has happened). The vehicle was not driven afterwards until the very first hill causing stress and ultimately breaking the conrod.

All theory of course until I can get this engine out and assess the crank properly.

So far the crank looks fine and so far the damage looks only to be caused by number 2 piston and as you can see in the pics the tell tale signs of a severely bent conrod shows all signs of a lock.

We know for a fact a litre of oil went into the engine.

We know for a fact it was also being burnt as you mentioned above.

I have many bends in my IC piping and I also have a silicone 3" reducer to 40mm going directly into the OEM elbow to inlet manifold. When I first found out I lost oil you may remember pulling the piping off to find a substantial amount (couple of tea spoons) pooling in the reducer just before the intake which could feed significant amounts into the chamber(s).

Also, I can confirm when running my own tests that the old turbo's leak was getting worse after the engine was running for 30 minutes.

All theory at this stage but so far it is indeed very very plausible pending crank inspection of course.

FWIW it may have been an overpressure rather than a total lock IE sufficient oil in the chamber to raise the cylinder pressure enough to cause the initial damage... then, tick, tick tick, BOOM... just like a... nah... better not say it

Exactly, I'll have more conclusive answers soon!

So if he cleaned the maf this might not have happened.?
