Hmmm - I have never had a problem with this plastic piece. What are the symptoms?
My 1995 Oldsmobile 88 Royale is at 118k and the only one major repair to be had was the intake manifold. Replaced it and it runs like new. When I took it to the shop the mechanic knew exactly what it was and had my car done the same day. It still gets nearly 30 MPG highway and 20 MPG city even with the mileage. If you are considering a solid used car buy, this is it!
The eventual failure sounds like what I had with my '95 88 Royale. Ended up being the drivetrain PCM that needed to be replaced.
God that was expensive, but not as expensive as having the plastic intake manifold replaced... that was a $700 dealership repair that I was not ready for. : (
Happy owner of a 2000 Ford Crown Vic now :)
My 1995 Olds 88 has really done well. I blew an engine (my fault) @ 104K. It now has 190K. Still runs tight, but lots of little things every couple of months, i.e. master cylinder, brakes, O2 valve, etc. I'm torn about keeping for another year, or should I get rid of it while I still have $ in my pocket?
"Hmmm - I have never had a problem with this plastic piece. What are the symptoms?" On mine, it was running great. I shut it off to buy gas, and it wouldn't restart. Some first symptom! There was antifreeze in the cylinders and it turned out to be this. On the bright side, this was at about 140,000 miles and it'd just started burning oil, about a quart every 2000 miles, and after this repair it never burned another drop. I'd probably still have it if it weren't for the wreck.
