Is there supposed to be a cover beneath the spoiler to prevent rain getting into the engine bay?

[DW964]

Hi,

My first thread and maybe most stupid question seen on this forum yet...

Is there supposed to be something underneath the spoiler / engine cover which prevents rain from going through the vents directly onto the engine and electricals?? My '91 964 has never had one in the time that I've owned it and I notice that it gets a little jumpy on start up if it has rained hard overnight. Seems odd that it would be designed such that rain falls almost directly onto the distributors!

If I'm missing a component, let me know. Pics and / or details of where I can get one would also be appreciated!

Cheers,

Dominic.

nope - the rain passes through the grill and onto the engine. I suspect at speed a lot of water flows off and what does not get zapped by the hot engine. The distributors are water tight and any morning grumpiness is probably due to air moisture rather than rain - that said spaying the electricals with an auto repellant is fine if the cars sits in rain a lot, ie in the UK...

Yep, agree with Alex's reply. When I recently changed my engine mounts I noticed that Porsche had even put drain holes in those because they're dished and potentially could collect water (wouldn't be an issue with normal mounts). Engineering design at its finest []

Welcome Dominic... hope you post many threads.

The only thing I've ever done in this area when I first got the 964 was to get a roll of self amalgamating tape and with some of the more 'exposed' connections/components with cabling attached I simply taped up the joints into the component. Peace of mind really and looks more like a heat shrinked sleeve than the odd bare cable or two sticking out of sensors etc here and there, if you know what I mean. However, follow Alex's suggestion regardless anyway...

I bet it's a lot cheaper than going to a vet![]

Thanks everyone for your quick replies!

Alex - any examples of teh type of spRay repellant / sealant (brand name, idea of cost, where to buy etc)? ...One that will allow my car to continue to dream of settling down, starting a family...he he []

...Geez, what am I talking about...?

Cheers,

My 964 used to rubbish in the wet until I changed the distributor caps and rotor arms so you might want to check what state they are in. Cured the problem.

 

[DW964]

Yep, done all that and more (see my replies on thread for 964 as a daily driver).

New dizzy caps, rotor arms, ignition units, coils etc have certainly improved running and early winter morning behaviour but it can still be a little jumpy after particularly heavy rain in the night - and I mean those monsoon style summer downpours. The wiring loom was replaced about 10 years ago but I guess thats plenty of time for it to begin breaking down.

Its not a big problem to be honest - sorts itself out in 30 secs or so usually.

Cheers,

Dominic.

Just guessing... but wouldnt the spoiler curtain cover the dizzy's somewhat when the spoiler is down folded away. It does have to be somewhere and the dizzy's are in the lower half of the engine space.............

Que???? You lost me with the curtains...

 

[DW964]

Cheers Gaz, you've got me thinking that maybe this curtain thingy is the bit that I may be missing (even if it doesn't actually fix the problem). I can't recall ever seeing a curtain but I'm going to go play with the manual spoiler actuator to find out! Any excuse...
