have a 94 ,2.7 td and went through a puddle that was a bit deeper than thought. The water went up to head lights and turned it off quick . Towed it out and took the air filter out soaked through no water in the filter housing. started first time but now misses a bit about 1500rpm and has white /blueish smoke . apart from that it runs fine no loss of power could it be a bent con rod or valve? It seems to clear a bit when driving but smokey when ticking over any help appretiated cheers.
