A thought occurred to me as I worked on my spider set up, that the partial flattening out of the PCV hose as it clears the other breather elbow at the turbo end of th air duct pipe, is that it gets a bit squashed and may not breathe as efficient as planned by the engineers.

A 100km drive up and down the highway the other day , parked the beast, and for the first time I see an oil leak evident on the floor. Dropping directly from the gearbox drain plug (lowest point?)

I am yet to smell gearbox oil to see if it is engine or the pungent 80W90 stuff.

The 80mm dia spread on the floor had no smell - so likely engine oil, likely rear main oil seal that has 600km on it

Only did it in the last 100km, not the great mix of driving for previous 500km

I am thinking I need to rig up a catch can, breather and hose config to reduce the possibility of the factory PCV system not coping.

There is very little chance of getting factory breather hose to PCV valve to full flow capacity in its tight fit

Anyone else considered this with the spiders?

edit >> I should add that the PCV valve is nice and clean, works etc

Catch cans are great as long as they are close to the PCV and don't have hoses trailing all over the engine bay.

Why?

On my brumby I did just that. I put in a catch can to eliminate extra oil vapour. only to have the nearly 2m of hose and catch can create condensation in the can and pipes.

With my last EA81 as it developed the death knock in the mains, also started with PCV issues - so much that the oil cap blew off! The next engine also had same issues and had me worried in its early days with 370,000km on it. I connected a rescue cord to the oil cap after the second loss , to save the next guy on the highway from trying to toot me at 120 kph. Never blown off again ?? I then hooked up a catch can to LHS rocker vent then to feed to PCV. It has caught very little oil, or it leaks out at an acceptable rate

My ideas with the EA82TS is to use a spare oil fill tube and fit up a breather pipe to a can or just hook can up between LHS rocker and continue on or catch it at the back of the spider where it resembles a pretzel.

Hmm...maybe cut a filler tube shorter and fit a breather to the cap??

I don't think I've ever had high crank case pressure problems with my EA82Ts . I've never had a cap escape , actually maybe one because the seal was shot . The current one may have two seals and possibly one from something else .

At USMB they spoke often of ratty PCV valves and the fix was to buy a new OE one .

The cheats way to get formed hoses is to dig through heater hoses .
