I am debating on going ahead and getting the head gasket replaced on my 1995 e320 wagon with 127,000 on the clock. Right now all it is doing is leaking oil out of the rear and out of the timing chain cover in the front. The car does not burn any oil but it does leak about a quart every 3 months. I plan on keeping the car for another 100k if everything holds up. EGR is also plugged.
Question, should I let it go until it has to be replaced or go ahead and spend the money and not worry about it any more. Also, if I did it now should I get the head worked on or just replace the gasket.
On a scale of 1 to 10 how difficult of a job is this. I would like to do it myself or should it be left to a pro.
Thanks
