2.25 Petrol Engine Positive Crankcase Ventilation

Hi everyone,

Before I take Putt-Putt to one of our trusted Land Rover mechanics for diagnosis and repair, I'm looking for the some potential input to addressing the positive crankcase ventilation on the 2.25L petrol engine or lack thereof.

At high engine revolutions, e.g. driving down Hwy 1 at 85km/hr, the inside of my engine compartment becomes well lubricated by oil spewing out of the engine breather cap fitted to the oil filler pipe. To date, I have been covering this cap with a perforated plastic bag in order to minimize lubrication of the engine compartment and contamination of our precious environment.

Note that the rocker cover breather on my 2.25L is connected to the air intake elbow via a rubber breather hose. Previous examination of this hose found that white condensate appears to have accumulated in this hose.

Potential courses of action that I am contemplating include:

1. Take truck to mechanic.

2. Remove the filters and wash the gauze thouroughly by swilling the units in petrol. Re-wet the gauzes by dipping in clean engine oil and shake off the surplus. Replace the engine breather filter and connect breather hose.

3. Complete 2 above but also remove the rocker cover, clean our condensate (if found), refit rocker cover including a new rocker cover gasket.

Your guidance to addressing this as inexpensively as possible is most appreciated!

I really need more information but .......if you are running the engine with the dip stick oil on the top mark you likely have too much oil in the sump especially for highway work. The top mark is really the "maximum level" not the "correct level". Depending on the stick the level should be between the two lines.

Does the engine run well otherwise?
