Chrysler 2.5s don't make 300,000? Oil blowback.

[89ARIES]

I was shocked and dismayed this morning cause when Bill and I pulled the throttle body, we saw pooled oil in the bottom of it. Bill was telling
me that the Chryslers had a design flaw, where on average as early as 75,000 miles, oil pressure starting forcing oil into the throttle body where it
was burned with the gas. Of course my first concern was rings, but my engine has excellent compression, power, and no blue smoke. In fact, when Butch and I pulled
the head in 2009 at 160,000 miles, the engine looked quite healthy bottom-end wise. Bill was telling me no matter what you do, its a matter of time before the rings wear
out. 150,000 is when a K-car is considered high mileage. Mine is already 187,000. Now, when Rick, another family mechanic, did my first headgasket job in 2004
at 66,000 miles, he charged me $1300 and replaced other parts of the motor. He may have replaced the rings, but not sure. So, then maybe my engine could
be considered high mileage at 216,000 miles, not 150,000. But, I am not sure if he did replace the rings. Also, oil seems to be leaking from multiple places now
on my motor, like forced out around the dipstick tube. So, naturally I check the oil level frequently and top it off. With all the repairable leaks and seals, I think I am losing
about a quart to 1 1/4th quart every 3,000 miles. Most Ks for sale seem to be a little low on oil. Bottomline, don't top of the oil, don't have a K-car. So, can someone hear fill me in?
Can I get my car to 300,000 or maybe its time to stop driving it all the time before I wear out the engine.

Doesn't help by the way you drive the thing....our 86 Reliant had 375,000 miles it was a 2.2, didn't burn oil nor did it have blowby, of course we changed the oil every 2500 miles. and maintained her like a new car even though she was severely rusty.

[88 aries]

Lets see flooring the thing up to 90 MPH that equals 5,000 RPM at the lest, maintaining high speed freeway speeds is around the 3,000-4,000 RPMS, take in mind thats why I got a V6 corsica instead of the four cylinder, I can cruise 75-80 at a lowly 2500

[89ARIES]

That doesn't help explain to me anything. I don't floor it up to 90 all the time. Maybe the 2.2 is a better design. I also did oil changes every 3,000 miles. It really pisses me off this oil thing.

[88 aries]

you drive those freeways all the time..you keep up with traffic. at 75-80ish im guessing, Let me put it this way the faster you go the more life you take out of your engine... the 2.2 is the same design as the 2.5, Its all in the matter of how well you treat your car, you my friend don't treat yours well...if you want to go fast go out and purchase a 426 HEMI or something.. and the thing about the oil in the air filter is a bunch of bull**** my 2.2 has 100,000 on her and she is dry as the day it left the factory, my 88 has around 140,000 miles and its dry, the 81 has 85,000 miles and its dry as a bone as well.... our 92 Buick lesabre with the famous 3800 series I has 389,000 miles and it doesnt burn a drop of oil nor does it make any kinds of sounds, only the body is severely rusted...

Your 89 2.5 liter is a better designed engine than the 86 2.2 liter if you compare Mopar 4 cylinders.

Occassional abuse of the car can cause permanent damage. Also driving a car that that is not running properly with the correct fuel mixture causes premature wear to the engine. If you run it too rich, the extra fuel in the cylinders tends to reduce the lubrication of the cylinder walls resulting in premature wear. If you run it too lean you can sometimes get higher local temperatures within the combustion chmber and do damage like burning valves. Lots of other factors also contribute to engine life: initial break in, quality of oil used, having a dusty air environment, potential damage done when the car is overheated, percentage of city driving vs highway driving, bad driving tendencies such as jackrabbit starts, rapid accelerations, opening up the car at the top end, and revving the engine excessively under no load.

Okay, so lets say the rings are fine, but the oil is still somehow getting by, how many miles do I have left before it fails smog. Should I just drive it like an old lady?

[88 aries]

how do you know the rings are good? you just cant go assuming... as for the 89 engines being better umm personally I dont think so.. we had an 89 aries that burned oil, and had blow by,it was a POS.. we didn' t have it long

[89ARIES]

Well, I assumed the rings were good because of a compression test. At what point though does oil consumption cause smog fail, low compression, and low gas mileage? I am just curious cause mine is still in the 20s.

[88 aries]

don't know we dont get smog tested here...
