<div> <font size="3">Not all RTV sealants are created equal. Some will tolerate engine oil and others, not so sure. Check the manufacturer's data sheet (which are typically only available online). I have not found one that is tolerant of gasoline. If the sealant is not tolerant it will swell up and flow globules as you mention. Frankly, I'm only comfortable using RTV on coolant applications but I have used it to stick my new Silicone valve cover gasket to my valve cover. I prefer Hylomar for paper gaskets. Perhaps those You-Tubers are getting compensation for product placement. (Jus' sayin')<br>

<div><font size="3">One recommendation I heard is to apply the RTV sparingly but equally, assemble the parts and tighten the fasteners finger-tight. Wait about half an hour and THEN torque down the fasteners. This will allow the RTV to take a set and not ooze out into the space where it should not go.</font><br>

Subject: [Shop-talk] Using RTV gasket maker<br>
<br>
<div dir="ltr">Seems like every video of someone working on an engine has them using RTV gasket maker with a paper gasket, yet buried in the manufactures literature it specifically says not to use it to hold a paper gasket in place. <br>
</div>
<div dir="ltr">I’ll admit I’ve done it and haven’t had any problems. <br>
</div>
<div dir="ltr">What says the group, what do you use on gaskets?<br>

<div dir="ltr">PS: and yes I’m aware of the “ globs” problem of fouling the oil pump screen. I use a thin coat placed closer to the outside edge.<br>
