Title: Smoking
Post by: Carlton on 15 February 2010, 09:49:12

Hello

Just wanted your advice, started to notice that when the miggy is firsgt started (especially from cold) there is a grey/blue smoke puff from the exhaust.

Is this common or the start of something serious

TIA

Unless there is a great deal of 'smoke' & it is constant, then it sounds pretty normal to me. Don't forget that in this cold weather, any water vapour coming from the exhaust will show as 'steam/smoke'. Keep an eye on it for a while to see if it gets worse. HTH :y

Thanks for that info.

Definately smoke as oppossed to vapour as you can smell it. Like I said tho its only happens with the first couple of revs.

Its common on the 2.6 due to valve stem oil seals. Just keep an eye on oil levels

as ElitePete said it's a known problem on certain 2,6 engines, the seals were changed during production. Wonder if any 3,2 has the same problem? And to fix you need to have the heads off, or am I wrong?

You can change with the heads fitted if you have the correct tools.

Its an issue that affects the first 12 months or so of 2.6 engine production (note ENGINE production, not vehicle) but, is not seen on the 3.2.

The fault is caused by some low life purchasing scrote who decided to save a penny on each stem seal.....

What you will have fitted is a red coloured seal which goes hard and causes oil to pass down the valve stem as it becomes loose on the valve guide....

Heres a few pictures:

And the correct tools are...? Spring compressor, what kind? Any pics? Adapter to put air on cylinder, anything else special?

No pics sadly.

Its a bar with 2 brackets on. Each bracket screws into where the front and rear cam caps go....the tool than uses this bar as a pivot with a lever to operate said device at one end and a fork type setup to compress the spring at the other.

Feed string/cord down the bore when the piston is down the bore & slowly lift the piston till the string is slightly squashed against the valves. That's how we did a car (Ford) of my Dad's.
I'm sure Mark will give a pointer to the actual tools required to compress the valve springs in situ  ::)  ::)  ::)

Valve seals

It would be rude not to fit 3.0 cams and inlet divider!
