I'm starting to think that putting on some RTV -- instead of Permatex Spay Sealant -- might be a better idea, simply because I suspect the spray sealant will end up creating a massive mess, since I can barely get back in there to mask things off, let alone hold the spray can... plus since it's near the top of the engine, all the excess will run down and coat everything below
Q: can anyone suggest the best RTV to use?
I saw a new special *flexible* version of Permatex Ultra Black Maximum Oil Resistance at the store... maybe that's a good idea since I am at the junction between 3 major parts of the engine
I suppose the most important criteria is which RTV will stick the best to the probably slightly oily surfaces, and also will hold up over time at high temperatures
I'm also thinking that I could apply the RTV using a small brush, instead of my finger, for best coverage/adhesion
it will be difficult no matter what, because the area in question is at back of the engine, not visible at all (except with a mirror), and the working space is very tight
