I know the alternator is a weak point when playing in water with a classic but has anyone found muddy water getting into cam belt area behind plastic covers , mine don't appear to be the most robust of things and not sure how well they seal , with more offroading planned next year I didn't want to have premature cam belt failure due to muddy water ingress

dont think that should affect it really but I am no expert in this matter

Not heard of any problems with this,but if you do end up doing some serious wading it might be wise to remove the cover and do a bit of house work after you've been off road.You should always wash down underneath and clean the brakes after a day in the mud anyway...

My timing belt jumped a tooth in the water during a forum outing at Inverness, on taking the covers off there was plenty of evidence of dirty water having got in, however I put it down to an incorrectly tensioned belt being aided to slip by the water.

I put a gates belt on and was in the water with it several times after that with no issues.

is there there a crankshaft breather available for the l200 like you get for the land rover 300tdi engines or is the cuver not sealed on the l200 engine

The l200 engine only has a plastic cover over belts , not much there to stop water and mud ingress

I get in some muddy water there allmoste every time I am out but no problems so far, just giving it a good clean.
