I’m not really concerned about leaking. I’m slightly worried that this stuff could hurt the engine. My engine building guide states “coat the plugs with a Teflon based liquid sealant and tighten firmly”. I’ve used a different brand Teflon sealer that was silky smooth and doesn’t have the “gritty” texture that this stuff has, but I didn’t have it on hand for this build so I used the stuff above. I’m trying to balance the slight risk that this stuff will hurt the engine vs the hassle factor of dropping this thing into the pan. I was given this product by a friend who builds frequently and he says he always uses it. Is there any risk the above stuff could hurt the engine?
