Hi I was just looking in under my oil cap and the rust buildup is worse then I thought. There is rust pieces all along the pipe and at the bottom if I shine a light threw it there is a jam up with rust I mean it is covering the bottom with a layer of rust how can I solve this. I heard some people used a shop vac and sucked it out will this work?

 

What happens when you take a shower and there is no ceiling fan except for a bathroon window.

Simple, the room needs to be filled with steam before the steam exits through the window. based on that logic, what happens to the bathroon ceiling and upper section of the bathroom walls.

 

I have no idea what you said or mean by that logic.

 

Maybe needs a poot fan?

Sent from my iPad using RX7Club. how bout that!

 

I think it has just been neglected I don't think the engine has been clean since the 80's there is a 1 inch layer of oil on every single inch of the motor.

 

Mildew will build up. With the motor, condensation will not vent properly. As the result, you will see milky substance on your filler neck and cap.

Ps. If im not making sense, myapologies as i have been working on my dd and drinking all day lol

 

Nothing like that. Just the rust buildup the oil looks fine when I check the dip stick. But the oil was just changed and not really driven.

 

Condensation turn into rust over time. Thats why we dojt recommend starting the motor and then shut it down without a full warmup.

 

So how can I fix it?

 

Drill a few tiny holes on your cap or one large hole where you can screw-in 90* fuel fitting (any size you want). Be sure to clean the cap prior to installing it so you can see the difference. Thats the simplest thing to do

 

And what is that going to do. Do I need to clean out the rust in there first?

 

The hole in the filler cap lets the steam or condensation out. It's as easy to understand as that.

Now ask yourself how are you going to "clean" the rust out? You might knock off more loose rust than you can possibly clean and it will fall down into the oil pan. You might just leave it alone for now.

Drill the cap for now. If you don't have a 90 degree fitting, don't worry about it for now. Just drill it and it will let the moisture out which, on your car, is causing the rust.

 

You can remove the oil filler neck also but tappping it with a rubber mallet. then use a wire brush attached to drill but you need to be creative for this. to reinstall, recoat the base of the tube with silicone and let it dry. With silicone, the right stuff is the best IMHO to keep it in there. All others dont hold well

 

I don't know what I am doing with the engine yet I mean it looks like this engine has not been taking care of at all like it sound I might take it apart clean it make sure everything is good and put it back together if I am putting it in a new shell want to make sure everything is right.

 

i have the same problem with the oil filler tube as well. i recently bought my rx7 a few months ago, does tapping the oil filler tube with a rubber mallet really work on removing it?

 

Yes since its pressed in

 

ok, thanks ill try it out tomo
