#723 of 3300 intakes - part deux!
Feb 07, 2001 (11:33 am)
The TSB covers all the 4.6L sohc's from 92 through 97 model year vehicles. These engines typically are in Crown Victoria Grand Marquis, Thunderbird/cougars and finally the town cars. The problematic intakes typically experience what is called heat/thaw fatigue which is an accumulative damage as the vehicle undergoes each and every time the plastic resin intakes heats up from the engine being used then finally cooling down after the engine is shut off. Keep in mind the 4.6L engine was released in the 1992 model year and to date no one in the aftermarket makes a replacement other than the one ford sources from it's supplier. Plastic resin was used during the design stages since a cooler incoming charge of air is beneficial to maximum combustion of the air/fuel charge. The Ford engineers also elected to use non metal simply because it would cut down on vehicle weight to improve the CAFE results mandated by the government. Nothing much anyone can do to prolong the longevity of the intakes other than to stay vigilent stress cracks and the dreaded plume of white smoke as the coolant eveporates after contact with the exhaust manifold and other hot engine parts.
#724 of 3300 Intake for a 95?

SWONG1: I read your last message indicating that the TSB covers 92 through 97 engines. Why? My 95 has a aluminum intake manifold. From previous postings, the bulletin only covered 96 and 97 model years. Thanks.

Congratulations R92688 you are one of the select few fortunate enough to have a non plastic intake but for the rest of us not as fortunate that is why Ford's Technical Service Bulletin 97M91 was issued. In your post you neglected to mention what you were driving and since I cannot read minds lately you might want to visit your local Ford dealer and query them on this TSB. Pay special note the "97M91" which I decipher to be model years after 91 and pre 98 which makes a lot of sense since the '91 model year CV was the last year they used the 5-liter 302 block and starting with the model year 98 they used the second revision of the dreaded intake which is now undergoing it's third revision starting in year 2001). You might also want to visit www.corral.net/forums/ and you will get a good taste of Ford quality!

how did you find a '99 Vic with only 400 miles? was it parked behind an Excursion in some dealers lot for 2 years?
#727 of 3300 My 95 CV LX, White (non H/P issued)
Feb 07, 2001 (5:57 pm)
SWONG1: I have a 95 Crown Vi LX with 99500 miles on the odometer. It was a 1 year old program car with 36K on it when I picked it up. The only problem on it was squeaking brakes which I had corrected with new front rotors and pads. My car is not equipped with the H/P options, but I had added cat-back dual turbos (not too loud, but nice sounding)and stiffen the suspension for handling and added a trans cooler. To breath better, I had removed the air cone silencer. Its hard to beat the comfort that the Vi offers and performance and safety. The dual exhaust increased my mpg to 19 in city and 24 on highway. Of course, my car is standard equipped with the 2.73 differential, but it has no problem smoking the wheels. While I'm not young, I do enjoy my 90's muscle car.
I had always admired the CV for its service durability.

I couldn't believe it myself! I was at the dealer and test drove a 2000 and a 1997 and wasn't really happy with either one. As the salesman and I were walking inside, I noticed TWO '99 CV's sitting in a line of F-150 trucks. They were in plain view, not hidden! I walked over, noticed that one was just what I wanted: Dark Green LX, Handling package, lumbar support, ABS, and NEW!!
They immediately dropped 5000 off the sticker plus offered me $1000 for my rusty 1986 Suburban.
I countered with an offer of $18000 bottom line, and we finally agreed on $18400 including all taxes, fees, etc. The only reason I can see that they still had it is because most people would rather spend a few thousand more for a 2001, but I am perfectly happy with this one! It actually drives better than the 2000 I drove.
And.... they have one more still on the lot! It does not have the handling package but it is an LX.
#729 of 3300 Congrats to you Bakertank!

What a great find! Best wishes to you for many many satisfying years of CV ownership. Ken
#730 of 3300 Glad to get input on 97 plastic intake
Feb 08, 2001 (7:54 am)
swong1...much appreciate information, now I know what it is like to be "between a hard place and a rock" as the saying goes. I am concerned about being stranded..as the improved reinforced parts come out,will they fit on the 97 since they will be designed for later years? This car handles well, and we were pleased with it..2001 Consumer's Report still states the 97 and 98 Grand Marquis cars are reliable cars, and have the engine listed as needing no repairs.Maybe their editors should read Edmunds Town Hall! At least when the intake manifold "blows" we will have a clue to what has happened.

wow! I could've bought a '99 Vic without the P/H package and with 19k miles on it for $18k... and I thought that was a good deal... I guess it was your lucky day!
