I have a 95 SSEi w/ the supercharger. At this time I have a fairly significant oil leak on top of the engine. Both sides of the intake manifold appear to be wet...more on the driver'* side than on the passenger. The starter and oil pan are real wet underneath too. The back of the engine is not very wet.
I haven't yet sprayed off the engine to try and start with a totally clean block. I did just change the oil and wiped everything clean with a rag as well as I could. I also cleaned the garage floor so it was spotless. I came home from work and overnight there was a puddle of oil that was roughly 12-15 inches in diameter. It is motor oil, not tranny fluid or coolant.
I have been researching this site and it seems the common problem is coolant leaks with the non supercharged engines.
This car has been relatively trouble free, so I really haven't done much engine work on it. I have replaced the cooler lines on it, so they do not appear to be the problem. It doesn't seem to be the valve cover gaskets...that would be a relatively easy fix.
My questions follow:
Is it very common for this model to have such a significant oil leak from the intake area?
If the engine were off, and there was oil in the intake/upper head area, wouldn't that drain down to the oil pan rather quickly therefore not allowing a large oil puddle to start on the garage floor? Every day this oil puddle becomes about the same size (12-15") after cleaning the floor.
Is it that tough to replace the intake gaskets on this model?
A lot of the data here speaks about the non supercharged models. Are these much more difficult to do?
I've been thinking about doing this myself simply becuase it seems whenever you bring it to a garage, they damage or break something else and try to get you for other repairs. The mechanic I've been bringing my vehicles to for years is getting close to retirement and doesn't want to go on a leak hunting expedition, so I either have to find another reputable mechanic soon (hard to find) or do it myself. I feel confident I could do this, it'* just that I don't want to break off a bolt in a head and turn this into a major project. Time is also a factor. I work 50-60 hours a week. It'* hard to find the time to do a job like this. Plus I'd have to rent a car while mine was down.
If anybody has done this job (replacing intake gaskets on a supercharged 1995), how long did it take you?
