Darksidesm Posted August 20, 2018 Share Posted August 20, 2018 I got my truck started up on Sunday. Got it to idle just fine. I do have some white smoke coming from the passenger side from under the exhaust manifold shield I believe. I'm assuming a break or a bad gasket. 1. If it is broken, what's a good replacement? Where to buy? 2. I also think my valve cover gaskets are shot. See pics below. Lots of oil. So valve cover gaskets. Where to buy? Cork or rubber? Do I need a sealant? 3. I have a few wires running across the top of my engine. Should I wrap these in electrical tap or use a plastic cover? Most of the old covers are rotted off and the wire is touching the engine. 4. Anyone have the additional battery for a camper? Mine appears to be factory installed. Has anyone ever disconnected this system? 5. Anyone ever bought covers for the "I believe they are called pockets" a long the top bed rail? I'm tired of chasing wasps out of them. Here is the smoke. Not real easy to see. Here is a valve cover bolt. Thanks Link to comment Share on other sites More sharing options...
ctubutis Posted August 20, 2018 Share Posted August 20, 2018 My guess is oil from the leaking valve covers is burning off the exhaust manifold. I like the rubber gaskets myself, I glue them to the valve covers using some sort of gasket sealant (Permatex No 2, for example) then just snug 'em down with the bolts, this allows the valve covers to be removed & reinstalled easily in the future. Don't overtighten, valve covers are pretty flimsy material and the sealing surface should be flat & clean. Link to comment Share on other sites More sharing options...

I will have to pull that shield off and check. Hopefully it's just the leaking oil. One last thing to replace. I will look at some rubber gaskets and that sealant. Thanks Is there anything I should check or replace while I have the valve covers off and the emissions spaghetti out of the way? Link to comment Share on other sites More sharing options...

Yes, check all the vacuum lines for cracks, melted areas particularly where they pass over the exhaust crossover are of the intake manifold. On the "spiders" (air pipes to the exhaust ports) lots of penetrating oil and use a flare nut wrench on them lest they round off and you can't get them out. They have to come out to get the valve covers off. Link to comment Share on other sites More sharing options...
