I posted a thread the other day asking about my truck smoking upon start up after it sits for awhile. Some people replied that they all do it and I seem to remember some people saying it could be valve seals. Well today I stopped by the SVT dealer and they seem to think it is the valve seals. My question is, is it worth it to have them mess with the truck, with the chance of them screwing it up, or do I leave it alone and not let them touch it? Will it eventually hurt something? Any help would be greatly appreciated. Thanks.

 

i would atleast see what they have to say, because it might be something that needs to be taken care of.

 

If its your valve seals, your heads will have to come off and be taken all apart to change them seals. Id personall ask the dealer if they could just change out my heads instead for a set of 03 heads that come with full sparkplug threads Id definately fix it, cause it will only get worse and the oil will cause your plugs to foul often.

 

Have you adressed the all too common PCV oil sucking problem yet ? If not...... it's probably the cause.

Some of the pictures people have posted on here of intercoolers and lower intake manifolds SOAKED with oil are almost unbelievable. Looks like a big gooey tar pit.

Fix that problem first and see if the smoking goes away

Perhaps for a few weeks you could cap off the PVC system altogether and just run breathers on the valve covers. That would absolutely rule out any chance of oil getting in the intake through the PCV system .

If the smoking stops, then you could hook the PCV system back up along with one of the many common fixes.... such as... oil separator, EV98 PCV valve, or whatever.

I would just hate to see someone dump big money into doing valve seals and have it not be the real problem.
