John.
I have just gone down this path myself check my previous email around
mid June. Same symptoms after highway run spotting of oil on the rear
tailgate. My case there was compression in the crankcase. Caused by
gasses being blown by the rings. When checking the engine I noticed
the rubber hose running from the breather tower to the air inlet elbow,
(thats the S shapped rubber hose between the air flow meter and the
plenium on the inlet maniflods some may call it by a different name )
had collapsed thereby not allowing the gases to recirculate in the air
system. This hose is a tricky little devil and looked ok at first look
BUT on closer inspection it proved to be kaput which when rubber and oil
mix regularly happens often. There has been some posts recently on this
same issue. Tip go and take out a bank loan for the cost of the pipe.
I paid $25.00Aust. for 7inches. No funny wise cracks.
In your particular case I note that you are thinking of seals and I hope
that this is the case. Unfortunately my engine has a blown No 3
piston. Just to be on the safe side I would suggest having a
compression test done to check the state of your rings. My remedy I am
waiting to transplant a 2.7 Subar flat 6 into my van.
PS. I have been off line for some time due to system failure. I have
lost my address book entries. Some of you are shouting for joy I know.
Mark if you read this email me with your arrival dates again I also
lost all your previous mails.
