So I have been given a 1994 Plymouth Sundance 4-door with the 2.5L 4-cylinder engine. It has only 98,000 miles on it, and the body is like new, but the engine knocks loudly. Also, the “check engine” light is on, and the speedometer does not appear to work. I am interested in restoring this car, m…

There used to be a machine that would regrind and polish the throw on a crankshaft without removing the engine from the car. The oil pan had to removed of course. The machine was portable and there were machinists who would travel and provide this service to auto repair shops. I saw a machine ope…

A remanufactured crankshaft with rod and main bearings is $195 from O’Reilly Auto Parts, shop around, you may find a crankshaft kit for less.

If OP is just doing some diy’er experiments to see if something or the other is possible or not as entertainment and relaxation, good for them. Just take care to do it safely is all. OP may discover something new in the process, who’s to say? As posted repeatedly above, if the ultimate objective i…

I got the abrasive cloth in the mail today, and decided to pull the remaining 3 bearings and do whatever sanding is necessary. Other than cylinder #1, the bearings had only minor light scratches, and the crankshaft journals looked smooth and scratch-free. I decided to use the nicest-looking used b…

I have removed the engine block and transmission from the car, and they are now sitting on a dolly. The engine and transmission are still bolted together, but I did remove the 4 bolts connecting the flex plate to the torque converter before unbolting the motor mounts and hoisting it out. So now I …

I wouldn’t go through the labor of pulling the engine and transmission without putting in a new crankshaft, main, and rod bearings at least. And, as much as I’ve always preferred Chrysler products, a Sundance would not be one of them. This car belongs in the junkyard.

Hard to advise at all here since we have no clue what we are talking about… Make? Model? I feel like we are discussing a Honda for some reason but… Could also be Chrysler/Mitsu but again…guessing.

[image] bcohen2010: This is the “numbers matching” original motor Absolutely no one cares about that, nor should you. Pull the head, yank the bad piston and rod, take it to a machine shop to have the big end checked and re-sized if needed. Bring the crank and have it ground undersize, buy t…

Whoa…I dont know why or how but I didn’t begin reading from post #1… LOL That was strange… Oops Anywho…on one hand I want to discourage you from investing so much time and energy in a 94’ Plymouth Sundance…and on the other I respect your Gumption and willingness to wrench. It seems you are cap…
