3.0 valve stem seals

[harlowmaverick]

Any of you guys know if you can change the valve stem seals on a 3.0 in situ without taking the head off?
I'm getting plumes of grey/blue smoke on start up but it clears after a bit.

That will be a head off job I think, certainly was when my Fiesta was done :thumb2

Are you sure it's the seals, how is it starting ?, could it be the glow plugs ? I once had an issue of lots of smoke suddenly, I poured injector cleaner into the tank and it cleared the smoke problem, worth a try :thumb2

2.7 can be done in situ, do not know about the three, will have a look at the workshop manual, Rick

 

[solarman216]

do not have a 3 to look but if what I see on the book is right then it is a double overhead camshaft job so not straight forward at all, but could be looking at the wrong engine as getting double vision now Rick

 

[harlowmaverick]

Double vision eh!
Lol to much partying I think lolol

It starts fine, fires up without any issue apart from the plume of smoke!

Correct it is a double overhead cam and 16 valves, so guess it wouldn't be a simple job either way?

Are you just meaning you get an initial plume of smoke on startup or is it more than that?

I get a small puff of smoke out the exhaust when I start her up after a cold (near freezing or lower) night but all my diesels have done that and I've always considered that normal with older diesel engines :nenau

My old Shogun was terrible when cold and you should see the smog patch my 40 year old tractor leaves!

 

[Timbo_1975]

Is this starting from cold or hot or both?

If only from cold, cycle the glow plugs twice and see if that makes any difference.

I would personally be surprised if it was stem seals...

Called it :augie

The 2.7 can be done in situ, I've seen one done on YouTube :thumb2

 

[harlowmaverick]

This happens from cold, but can happen even when I have left it to cool down for an hour or two.
I start her up and a plume of this smoke comes out, not all of the time mind you, I Rev her up a few times and it clears.
I'm sure that it is valve stem seals because of these factors.
It starts on the button, every time.

Can you post a video of it ?
Is it using engine oil ? does it smell of burnt oil or is it diesel smelling smoke.
