I got my bobcat oil pan and dip stick last week, but I have not installed them yet. I will need to put in the new dipstick and an oil fill. I am would like to see your filler. Are you going to use a AN bulkhead fitting with a o-ring and jam nut? or tap for threads?
Does anyone know if there is a replacement valve cover gasket available that is re-useable silicone?

I taped it for threads. I will probably use an O ring to seal it to the valve cover and some Blue Loctite to secure the AN fitting to the Valve Cover. I will have to mark the bottom of the AN fitting to throw on my lathe to remove the excess threads that protrude inside of the valve cover.

Tomorrow I will update my thread with Pictures on the Oil Fill.

what size fitting? So O-ring on the inside or outside? I would think that you could put the jam nut on the inside and like you said trim down the left over. Hopefully it will clear the valve train.
are you going in from the flat top. It is too late, to go out to the shop. but if I remember there is a angled flat just off the topside of the VC towards the front of the engine on the drivers side.
I was thinking to weld a fill fitting on there. but a AN-12 bulkhead would work well too.

I believe I am going to use an AN-12 fitting. But no on the Nut as from what I have read from FTE that the rubber plug would contact the valve train and that rubber plug is probably not nearly as thick as a nut.

There is a spot on the front of the valve cover on top that looks like a knock out but it isnt :). I drilled in the center of that and tapped it for the AN-12 fitting. So the fitting will be threaded in from the top as well as the O ring on the AN-12 fitting.

The place that also looks like a knock out but smaller at a 45 Degree angle on the valve cover I will probably tap and use an AN fitting for return oil from the Isuzu Vacuum Pump like what Rangemar did. But I will have to ask him to make sure.

AWWWWWWWWWWWWW heck I will be back in about Ten minutes with a picture. :)

This shows the other part that looks like a knock out but is not. I believe that Rangemar used this as a oil return from the Vacuum pump.

Sorry it is all still dirty.
I was going to clean it all up and paint it. Then take pictures along the way. So these are now a Before. :)

By the way I have decided to paint the Engine Orange. Yes like the Newer Kubota Tractor. :) Kubota calls it Orange II but I hope to get close with a Krylon Orange made for painting Engines.

I'm just a litte curious why you went with the an fitting. I cut it with a 1 3/4 hole saw and used a gm oil cap from a s-10. It was $2.50 at autozone. But maybe I'm just cheap.

I just remembered that FTE said the bottom of the rubber plug would interfere with the valve train as in not letting a valve fully close. That is the main reason. And I had the fittings laying around. :)

No interference issues with mine the rubber doesn't even go to the bottom of the original divot in the valve cover

Rangmar I would like to ask are you also using the valve cover for the return for the Vacuum pump Oil and the Turbo? And if so how? Thought I would ask while I have the valve cover off for clean up and making holes and paint. Chevy Orange. :)

And if I should get lucky and have room I may add this 1 Gallon Canadian Windshield Washer to use as an Inter Cooler Water Sprayer with 50% Water 50% Alcohol as it gets darn HOT in South Texas.

Well the parts are now on there way from Leonard's. :) But they will not be here till Dec,3rd.

---AutoMerged DoublePost---

Well I am no Pro Painter or have a fancy Camera just a flip phone but it is good enough to go on an Engine and get greasy. :) Still looking for information for any further holes I need to make in it. But otherwise I think it looks decent in Chevy Orange.
