Water logged 1.9 JTDm engine- options?
I had to get to a meeting and drive (like many others) through tidal water which had come over the road due to the highest spring tide in 30 years on Monday this week. It was up to 250mm deep and lasted about 300 metres. I drove on the centre of the road camber to minimise depth and drove at a steady 5-10 mph with revs about 1500 rpm. The drive through was completely uneventful and went to the meeting and thought nothing more about it.
Five hours later I started the car to go home (tide now low and no flooding). Most ghastly mechanical noise - as if there was something hammering outside the engine! Stopped the car did a visual check of the engine bay and checked the oil and coolant levels- all OK.
I started it again and increased revs past idle and the noise was less physical. As I was 40 miles from home I decided to drive gingerly home. Once up to running temperature I noticed that any form of acceleration produced bad vibration from the engine- the higher the acceleration the worse the vibration. I therefore drove home not just like a nun but like a compete convent doing a sponsored silence! On Tuesday I started to car to find the same loud clattering noises and drove to my local mechanic.
He drove it round the block and straight into the workshop!- Water in at least one cylinder! Obviously due to the ridiculously low location of the air inlet.
There are now hard financial choices to make.
1. Find new engine- massive money
2, Find good used engine- where do I find one, is it likely to be compatible, what sort of cash and do other users engines (Vauxhall, Saab, Fiat etc.) work?
3. Take the engine out and re-build- 98000 mile engine, 2008 which I know and have (until now!) respected.
Have others done this? If so what is the best course of action and likely costs? I love the car, it is in great shape and I wouldn't want something else. Besides which it still has value.
