I am preparing to do the lower intake manifold gaskets, fuel rail gaskets, and valve cover gaskets on my 91 4.0L OHV. I have been referencing this thread, which has been incredibly helpful, but I still have a few questions. My main question is this:
1. Should I try and find a one piece lower intake manifold gasket like the thread I just mentioned suggests? Or can I go with the newer, non-OEM two piece gasket? If I go with the two piece gasket, won't there be issues with leaks around the front and back edges of the engine block in the valley (see yellow circles in pic)? I am confused why the one-piece gasket has a gasket surface on those edges but the two-piece simply doesn't. Is it because RTV is sufficient on those two surfaces with the two-piece? Any advice is appreciated.
Additional questions I have:
2. Any general advice on using RTV sealant. How much do you use? How do you apply it (just with your finger I think)? How long do you wait after putting it down and before joining surfaces?
3. What is the best way to clean gasket surfaces? I have heard of plastic-gasket scrapers. Is that the best way? Acetone?
4. Should I take this opportunity to clean or replace the fuel injectors?
