I should have left well enough alone in this case, but at least my engine is clean. They are pretty good engines. I drove a crew cab 2009 model in a previous job with the 3 valve 292 hp and six speed transmission and was able to get 16-17 mpg in town and 20-21 mpg highway! These differences were generally small and resulted from different piston stroke configurations. All in all, I have been quite happy with the service I have received out of mine. It still ran well but rust from daily city driving was getting to it.
Your application you referenced as 99. He contacted me a while back to see if I could be interested in it as he remembered how much I liked the now old 97. . The guy decided to stay with a 4. But please, stop calling them Windsors. I always coat the threads with anti-seize goo.
Quite the mpg difference in one model year. It is a very reliable truck. The intake manifold leaks coolant into the 4 plug 121,800 miles or 63,000 on the new motor. I took it home and washed the engine at a car wash and had a misfire as soon as I started it up. There is a similar issue with spark plugs on the 3 valve 4. The Marauder engine is basically the same as used in the Aviator and Mach 1 but only in the Marauder was it backed by a 4R7xW so you need a Marauder controller.
If the shell does break free then there are tools to remove it relatively quickly. Previous owner towed a sprint car with it for a couple of years, but you would never know. I have always been upset by the lack of respect the Modulars get, they have always proven more than adequate and the newer 5. Contacted manufacturer, no recalls or assistance. No problem getting them out. Fortunately the author has not encountered this on any of the 4.
Hope to still be hauling the boat to the lake with this little engine in 20 years, which at my current use would only bring it to about 200k miles. I know this truck will go another 100,000 miles with out anymore problems. They are pretty good engines. Sorry for the venting, just wanted to share the problem with the Marquis. General Comments: This truck by far is the best truck that I have ever owned. The manufacturer knows this is a problem and should step up and do the right thing.
The 4V motors are beautiful though. The only weak point was the big end cap set-up which could fail at the bolts if the engine was taken beyond the red-line habitually 5,500rpm max no problem with the factory bottom end. Sure it was smooth and quiet and relatively economical but the acceleration was glacial. Current thinking was that small bore, long stroke motors would be easier to control emissions in better swirl if I remember correctly. To order direct, call 1—888—490—6837. In regards to the oil consumption and the valve guide seals, I have not seen it as a big of an issue as many make it out to be.
Drivers seat sags a little toward the door from getting in and out, a piece is broken off and stick through the seat once when I was getting in. The consumer exited the vehicle and discovered it was not the tire. Ford will not even consider the thought of making this manufacturer's defect right. This is the same procedure I have used on all of my Corvairs; also equipped with aluminum heads. Did a fast and furious imitation.
I owned it until 2010, had 131K miles, well maintained, sold it, and now the 2nd owner wants to sell it due to his health issues, It presently has 210,411 miles on engine, most of his driving were all highway miles, and rarely driven much in Indiana winters but put in his barn. Times have changed as the aftermarket has caught up with demand. On to the car itself, I love it!!! All versions operated with the same firing order--1-3-7-2-6-5-4-8. This not only is an obvious mfgr. It had 631,000 kms on it. The only issue I have seen is spark plugs and intake manifolds.
