Tx for the read..I cut to the bottom of the article and just as I suspected, user error
is the prime suspect. Which is what I previously said, not everyone knows how to properly apply it. (you actually helped me prove my point, tx) People pick up a tube at the parts store and think, "I got this - what could go wrong!"... turns out a lot, if you don't know what the heck you're doing! The problem wasn't with the RTV, it was (likely) with the person applying the RTV.
I can not argue that in a high volume shop, preformed gaskets may provide some advantages over RTV. I say may
because there are RTV's that do allow you to place the vehicle back into service immediately. But whatever, using a preform in that environment is an equally intelligent option likewise, so I'm not going to beat that horse any further. Use preform or whatever you think is best for your business, what do I care. But this discussion wasn't (originally) about whether or not RTV is the best option for shops, it was about it's suitability in a particular application. But again, I digress...
Fwiw, I used RTV for my tstat housing, valve covers and oil pan instead of preform. Not a single problem; no clogged oil passage ways, no floating itsy bitsy parts collecting in my oil filter or radiator - nada, zilch! I guess that just makes me a freaking God amongst men when it comes to using RTV - you guys hiring, maybe I could be your RTV specialist guy or give a class on how to properly use it??? (before you get ur panties in a wad, I'm just kidding🤣)
...oh, and since we're boasting about "experience" with RTV, I've been using the stuff personally and professionally for oh, maybe 30yrs now. So there's that..🤔
Anywho... thanks for the discussion, it's been real and it's been fun...but not real fun. Have a great Memorial holiday!
