V6 misfire, water in no. 6 and scuttle foam sodden
« on: 31 December 2017, 20:32:28 »

As above. I have removed all plugs and found water in no. 6. I shall remove scuttle next. Is it forum policy to remove the foam?

It works for me ;)

Others might advocate sealing the scuttle, but ultimately it is the foam that retains the moisture which drips onto the cam covers and coil/dis packs...

Only petrol Omega not to have this issue, ie nothing below the foam for the water to drip on, is the 2.2 ;)

Not really.

Make sure that both parts of the trim are securely attached to the base of the windscreen.

When I got the Project MV6 from James he had just replaced the coil packs. After a little while I discovered that the scuttle foam was soaking wet and that the windscreen trim was insecure. I ended up pulling the trim off (and separating both parts) and giving it a good scrub to get all the moss out.

Since I did that the foam has remained dry. Pulling the foam off doesn't prevent the leaks it merely gets rid of the evidence..........

Removing it does allow the water run down/back to the bulkhead and on towards the chassis rail which is in turn designed and attached in such a way as to not retain water ;)

I did. All symptoms and effects of the scuttle leaking instantly stopped, with no downsides. It's quick, easy and effective so why wouldn't you?

A nice bead of silicone where the scuttle sits on the bulkhead always worked for me, and if the foam stays dry you know its sealed.  :y

I pulled the foam from mine,however I'm hoping to get another scuttle soon[mine's had a piece broken off it since I bought it.Assuming the replacement comes with foam then I'll try the sealant route.Ibelieve I've seen on here that sealant around the wiper spindle holes can also be a good idea.

The trim comprises a hard plastic channel that is a push fit on the bottom edge of the glass and a rubber cover trim that clips into the hard trim.

Get everything clean and  it won't leak.

Seal the water (and moss) in and it will make the metal frame behind the screen wet and promote corrosion.

Yep, there are 2 aspects to sealing the scuttle:

Make sure the strip attached to the glass is solidly fixed, or the water will, as Andy H says, find its' way under the seal and back behind the scuttle channel.

Seal the scuttle channel to the cabin filter box, using silicone if necessary as often the original foam has deteriorated. The wiper hole inn the centre of the scuttle is also critical as it allows water to drip straight onto the 1,3,5 coil pack if it drips. A little silicone here, or doubling up on the felt washers, often helps.

This is what I meant earlier by sealing the scuttle to the bulkhead, as the cabin filter box is part of the bulkhead really.   ;)

Do NOT remove foam. Its there for a reason (noise). Fix the original issue of the leak, not the symptom. Make sure the seal is fully on the lower windscreen edge, and that the scuttle is correction in the same seal.

Problem solved.

My thanks to all for advice.
I have removed the foam. It was sodden, heavy with water, if squeezed water dripped out. It was easily removed, I just removed 5 clips and it came off. I could replace it, but doubt I shall. I presumed its function was sound insulation, but car is not noticeably noisier without it.
