Hi All,
      Well here goes..I changed my cam cover gaskets again..but because I did not have time to finish the job..I left it overnight still needing reassembling..last night we had rain of biblical proportions..the upshot being the inlet manifold is now full of water!!...any ides what to do next..or what damage is likely if any to have been caused....I did try to seal the area off but with the high winds overnight it did not work!....any ideas guys??

Cheers Gord.

Can you get a syringe or pipet and suck the water out.....

Hi Mark,
         I've sucked the water out of the manifold..but what chances are there that water will have got into the cylinders? if so what then ?.

Cheers Gord.

Suck out as much water as poss, soak up any remaining with kitchen towel.
Take plugs out, remove both purple relays from ecu box then crank engine to blow out any water that may have got into the cylinders. If you think there is a risk of one or more cylinders being full of water then turn over by hand using socket on crank pulley bolt and suck out or absorb any water that comes out of the plug holes BEFORE cranking on starter.
A bit of wd40 in the inlets wouldnt go amis once you get the water out

Were both camcovers on? If not there could be water in the sump, the oil floats on top of the water so the pump would pick up water rather than oil. If so drain and refill

Hi,
  Yes both cam covers were on...I'm more worried about any damage that might happen due to water ingress into the cylinders? or the after effects ie water getting pushed trough the exhaust system..damage to cat's and such?

Cheers Gord.

Cats should be OK, they create water in normal use so should be OK once they warm up fully.

Cheers for that! I will try your method (if it ever stops raining here  )

Cheers Gord

Ps has enyone ever had this happen to them?  

[wigan pier]

Well I tried the method described previous..two of my cylinders were full of water I managed to feed a pump top off a window cleaner bottle (the trigger type with the long thin tube) down a plug hole to get rid of a lot of the water..then spun the engine to pump the rest out (well most of it)....then the rain started again .....oh well I hope there is no damage done! time will tell (fingers crossed).

Just need the rain to stop again (not that it seems likely).

Also check the dipstick for signs of water in the oil.  If you aren't running the engine today then spray some WD40 in the cylinders.

Hi,
I have checked the oil so far so good..and WD40 sprayed down the inlet manifold..just wish the rain would stop   ...the main reason for the water getting in was the scuttle was removed and my atempt to seal the engine compartment off failed  ...hopefully no long term damage  [smiley=undecided.gif]

Cheers Gord.

I meant down the spark plug holes of the affected cylinders.  This isn't a huge deal unless you leave it a really long time, however you don't want rust in the cylinders.  Therefore, unless you get the car running in the next couple of days I would suggest spraying WD40 in the cylinders and turning the engine over every few days just to be careful.  You know how brakes look after a heavy rain!

Yeah good point I will do what you suggest....someone else suggested the inlet manifold I suppose it can't do any harm to do both  

Cheers Gord.

If you remove as much water as you can, and if the water does not affect the spark plugs and the engine actually starts, you'll be OK. Water by itself will not cause damage - to the engine or cats - in fact in the early '90 there used to be a retro-fit water injection kit that injected water into the inlet manifold - it was supposed to help get a more controlled combustion process. The water will clear itself - but again as long as it is not excessive i.e. flooded cylinders etc.

There are many more... little water in the intake manifold is not an issue.
