Fumes in cab - V6 ?

[Jim the Box]

... is it just a case of removing the 4 holding down bolts for the seat runners and removing the front seat completely and then tilting the hatch up.

There's a fifth bolt behind the seat that secures the seat belt mounting track to the hatch. There will also be a connector to disconnect, but as long as the bolts come undone ok (not too tight), then you can whip the seat out in under 5 minutes. Good opportunity to check the gearbox oil, power steering fluid and air filter while you have easy access.

Raining again today, will check drivers side this week first chance I get, new to this so it will help me get familiar with the engine.The passenger side of the engine was spotless, fingers crossed its the same on the drivers side. Thanks for all the help and advice.

What would we do without forums?
I found this thread whilst searching for my problem similar to those in the original post.
i too get fumes in the cab, but it only seems to happen once the engine is up to temperature and the thrmostatt is fully opened. then i get the fumes for a minute or two.
I have checked the drive for signs of an oil leak, but as it is dark when i get home from work i haven't looked in the engine bay yet, but i will look for the signs as described in previous posts.
if i don't come up with a satisfatory explanation does anyone know of any Bongo friendly garages in the South Essex part of the country.
for the record, i have a V6 petrol
many thanks

What sort of fumes are they? Is it oily, exhausty, rubbery or plasticky? Try pulling the HT leads off the plugs and look down inside. It's not uncommon for the rocker cover gasket to leak which lets oil down into the spark plug bores.

We've had one or two v6s with this problem which i think, from memory turned out be leaky (crankcase?) seals, dropping oil onto hot (exhaust?) surfaces. Maybe Simon can recall the details?

[Simon Jones]

Vaguely rings a bell. There's no substitute for a decent torch and your own nose when it comes to trying to find this sort of thing. Any oil leak will leave a trace and if it's dripping onto the exhaust you should be able to see smoke coming off the hot surface.

I finally got the rocker cover seals replaced on my V6 last week. Apparently the seals had gone fragile with age, Oct 95. Cam and crank seals appear fine, but I intend to add some Forte cam sealent in the hope of prolonging things as long as possible. Does anyone have a contact where I can get hold of this? Geoff found a source on eBay I believe. There was a bit of oil in one cylinder, so this might have been causing the slight whiff I have experiencing occasionaly. Not much though the plug was fine.

Now I just need some more cold weather to check if the occasional stall on changing over to LPG has gone. Difficult to tell as I have changed my driving style and now give it a slight rev if I have to stop when it is near the changeover point. This has taken me through the last weeks of freezing mornings without any repeat.

I think it was Simon or Mike (apologies if I have got the names wrong ) who helped me source products which when added to the engine oil soften the oil seals and reduce the leakage, one was a whinns product, can't remember the name of the other, however one I added to my Renault Master van which seems to have stopped the leak, the other is in my bongo which appeared not to be leaking but i thought I would add it as a precaution anyway. If it does not do any harm I feel anyone with a V6 should add this as a precautionary measure and should help to prolong the life of the seals.

Its still available on Ebay http://www.ebay.co.uk/itm/FORTE-SEAL-CO ... 3ccd2e355d
Ours has definitely started leaking again, so it will have to be in for the work to be done shortly.

Forte Seal ordered. Unlikely to do any harm and it might do a lot of good, if the other seals are approaching the state of the rocker cover seals.
