I have oil seeping from the base of my filler tube. Does this just unscrew from the valve cover? Or do I have to pull the valve cover to remove it?

Also, what's the seal, an o-ring?

Thanks,
-Michael

Just unscrew the cap, then unscrew the filler tube, then replace the cap on the valve cover with no more filler tube. Problem solved.

Either that or take a spare light-bulb o-ring off of a junkyard car and put it around the bottom of the fill tube. That'll get you a few thousand miles. The only real way to solve the seepage problem is a new fill tube.

Thanks! I got it unscrewed, it came out no problem. I wasn't sure how difficult it should be to turn, didn't want to break anything. Saw the o-ring that was in there, replaced that and put some RTV on the threads. Will see what happens with the seepage.

Thanks again,
-Michael

Having the same issue- read the posts . . .
turning the tube seems to "catch"- dont want to break anything off in there, is there a trick to getting the tube off.

I'm presuming straight up lefty loosey, but then the tube seems to get tight and catch. My 9C1 is a mid 1995 model/LT1.

That works only on the '95 and '96, not '94.

I have seen people use silicone as a temporary fix. IMO the tube is ugly and the engine looks better without it, but it's practical when you don't have a funnel handy. ;)

It sure worked on my 94 and many other 94 I have seen. Maybe D body were different.

Dunno...maybe you're right. I've seen it work on '95 and '96 D body, but on my '94 Fleetwood the filler cap would not fit into the valve cover without the filler neck. I got a set of '95 stock valve covers to solve that problem. :)
