Hydro-Locked, I think it should be......

Basically it is where the engine sucks water in the through the air intake and forces it into the cylinders and fills the combustion chamber with water..... water won't compress, so locks the engine...unless you get it quick enough it can be terminal.... several thousand pounds of scrap metal under the bonnet as they need most bits to fx.....

That's the theory anyway.....

That sounds worse than it is though . . . . . a decent spanner man should be able to sort it in no time . . . . . not realy high tech aint TDi's . . . . that right dude?  :wink:


Me, I'd dry it all out first, then go for the compression check. If you get widely varying readings from that you can be pretty sure you need a serious engine strip.


Hope it's ok fella.

solihull-mick:
Just a quick note i had a customer that did the same, did get it running in a fashion, and i did compression check it, all the same psi readings, when i took the head and sump off cylinder no 2 had indeed bent the conrod, but no compression loss, i guess it ran rough due to the piston not reaching tdc there for not burning correctly, but still gave a good psi reading,

So beware if you get good compressions dont rule out a bent conrod :wink:
