Hydrolocked turbo diesel

[rfisher]

Anyone care to give me a step by step guide as to how you would check a hydrolocked tdi engine?

With a petrol engine I would take the air intake off, plugs out, stick a clean plastic tube into the cylinders to suck out any water and then try to turn it over with the plugs still out. If it sounded OK I'd assume the conrods were OK and put on a new air filter, replace or clean the plugs, change oil and water and try to start it.

Don't know how to do this with a diesel.

I'd use a silly straw.

Preferably green.

Your method of "checking" doesn't really check anything at all. It's quite possible for an engine to run with a bent rod.

A compression check would be one of the simplest way of testing the engine.

Same thing but with "glow plug" replacing "plug"?

Although I'd be tempted to check TDC height on all pistons was the same, as it's a slightly more reliable indicator of badly bent con-rods.
