<VV> Loose Oil Pickup Fit

[JVHRoberts at aol.com]

Well, it IS elastic, it IS fully captured, and as long as the surfaces are  
clean, it WILL stick. 
The abuses of RTV are well known and numerous, in these days of modern  
engines sealed by the stuff. The operative word is ABUSE. A thin coating on a  
clean tube inserted in a clean bore should be a no brainer. Done it several  
times, NEVER had a problem. 
In other words, used AS INTENDED, RTV will work flawlessly.

I'm not  implying RTV is not appropriate for a close tolorance fit. Heck, 
even the  factory uses it for valve cover and oil pan gaskets when properly 
applied and  cured. And that "close" tolerance is 1/8" +. I'm sticking my neck out 
on a  loose fit, where vibration can loosen material and hot oil washes 
against it.  Try leaving your valve cover bolts loose and see how long the RTV holds 
up  under vibration and hot oil. The oil pick up is held by one bolt if the 
end is  loose in the hole (original poster said it was loose), so vibration is 
an  issue in this case. As I said, if you have to "drive" the pick up in, then 
RTV  should not have to hold against vibration.

Others have seen so many  abuses of RTV with slivers in the oil that they are 
leary of using it anywhere  in the oil system.
