Default Where to mount oil catch can

A few days ago I got the oil catch can I ordered a while back. My thought has been to mount it somewhere in the engine bay but.. now I realize there just is no space even for a component of this limited size. So where to mount? In the space inside the right hand side front fender?

Pardon me for asking but..........what oil are you catching? Breather overflow? And yes, there likely is room in the right front fender. I just had my inner fender off and there is a catch bottle of some kind (I didn't investigate) hidden in there with maybe enough room for yours. Easy enough to take off. Nice looking piece you have there. TM

The bottle on the right side behind the well liner is the coolant overflow.

When I installed my catch can I just did the part load breather side and didn’t bother with the full load. Can’t help you with the location though, I removed the air box and there was space in that corner in my case.

Correct, it is the oil mist from crankcase ventilation I want to avoid feeding into the intake system.

Yes there should be sufficient space in the fender, I had the inner fender liner off before and from what I remember at least to the front there are a lot of empty space.

Wondering where others have put their cans, even though this is not a very common mod I know some folks has done it.

One con with mounting the catch can in the fender is that emptying it will require the liner to come off

Since this engine uses the traditional fuel injectors on the backside of the valves there is absolutely no risk of "oil vapor" causing massive carbon buildup.
I have opened up Jaguar V8s and found no serious carbon issue.
There exists the possibility that engineers factor this oil vapor into the design to provide a little lubrication. When one frustrates this occurrence, perhaps other things do not go as planned.
Oil vapor will not matter to this type of engine. If there is way too much vaporization of oil, look to other causes such as excessive blow-by or temperatures, failure of the PCV system or even the quality of the oil.
In other words, worry about something else.

The catch tank is now mounted in right hand side fender, lots of space available there. Full load breather hose connected to the tank.


Just got a new part load breather hose delivered from Sng Barratt. I see that the "middle" connector on the hose is supposed to attach to the intake elbow, right? And if I instead want to direct the fumes to my catch tank, that connector is where I need to tap from?





The other end of the part load breather hose is fitted with a short regular rubber hose



That hose is connected to a olive green pipe that rises up from beneath the coolant expansion tank. Where does that pipe go and for what reason?

This is the olive green plastic pipe beside the coolant expansion tank. Anyone who knows where that leads?

the intercoolers look disgusting from all the trapped oil vapor.

it is probably too late to make a difference anyhow unless you’re a fan of water/meth injection

Yes the interior of my intercoolers where covered in a brownish/greyish baked layer of something. Oil vapors was most likely one of the ingredients in the recipe. Worries or not, I prefer not to further add to what is already there

Also, the full load breather hose feeds into the air intake tube. Cannot see what good the puddle of oil at the bottom of the pipe will do?

The coating of the inter-cooler and other areas with varnish is another reason to use motor oil with low vaporization characteristics which we see with synthetics. Products like Mobil 1 synthetic have been around for a long time in my market. Side by side of nearly identical engines, mileage and usage over sometimes thirty years, i can see major differences when i help people to service or rework them even after hundreds of thousands of miles.
