ok i posted a thred about 2 weeks ago sayin my plugs keep fouling i suspected it was my rings but i dont think their the colpret now since i noticed that it doest chug smoke all the time but just does it when you rev it up , asked my dad who knos just about everything about cars if it might be the vavle seals in he said it might be , i totaly cleaned out all the carbon in oil out of the intake and valve ports to see if that would help it does idle alot better now thow but the plugs are still fouling i did a compression test today in it came up bad! 1st cly read about 75 and about 40 on the 4th one the two middle cyl's didnt come up with nothing iduno if its a bad compression gauge or what but still sumthin should have came up on the two middle cly's if it came up with 75 and 40 on the other ones , i did the test about 4 times just to make sure , might it be the head gasket??? theres no antifreez in the oil and vice versa and the temp gauge reads fine no overheating, could the gasket have blown out strait from the cly and not have gotten to enything else :confused:

the cars got about 180 K on it
 
havent got to cleanin all the carbon off the pistons yet (waitin for a warm day to come so i wont freez my ass offas much)
 
Sounds like rings or pistons. I had an engine (my first one) that had low compression and when I took it apart pistons 2 and 3 fell apart as I removed them from the cylinders. Lucky thing mitsu parts are cheap.
 
how exactly did the pistons fall apart? wouldnt they have bursted apart already underload by the engine. im just curious but bout how much did the pistons cost in do you have to buy them by the set (4) or can you get em individualy j/w what im in for as of cost wise if it is the pistons

ohh yea in anuther thing what should the ring-gap alowance (sp) be in a turbo engine im gonna check those if it aint the pistons

Your motor is used up, and for the love of DSM get a spellchecker. :rolleyes:
 
Just do what I did and build a stroker motor its pretty simple if you are mechanically inclined. Parts are cheap and its fun.
 
i would if i could (money wise) but im just lookin to get it runing right so i can have sumthin reliable to drive agin w/o breaking down on me

in Defiant whats with the "spell check" coment, thats for nerds get with the times LOL just messin, sorry though i was in'a hurry in kind of stressed in well i im just aliterate most the time
enyways back to the subject i guess
 
compression tester is crap now, i was doing the tests agin after i put a capfull of oil in the cly to see if that would change enything and when i was trying to unscrew the hose/bolt from the sparkplug hole the damn thing broke and left half of the compression tester down in the well still screwed in :mad: well now i gotta get that out somehow, but the good thing is that now im not sure if my first tests were right since after this happend, damn gauge still read 0 too! ahhhhh goin crazy
 
In my experience there is no such thing as a dsm that doesnt break down. If its not one thing its another. But then again we sure abuse them on a regular basis trying to beat 8 cylinder vehicles.
 
Dude in my opinion you need a rebuild. Or if you are lucky the compression tester is junk, sounds like it might be.

You can buy a new one and try compression test one more time. After that, and then putting a little oil in the cylinder you will know. But that compression you listed sounds really bad.

Besides the smoking, does it drive good and always start? Got enough power to get you around ok?


If you are really low on funds, and need a cheap fix (assuming it does get you around OK), just put some Luca Oil Stabilizer in it. That might help keep it from smoking as much. I only use this stuff in a worn out motor, not a tight one. I use it in my 1990 NT, and it works great. That car without iit, smokes alot and uses/burns oil. With Lucas in it (one bottle every 1500 miles), it doesn't use much at all, hardly any.

One of two ways to use it:

1. (recommended) Change your oil, use 4 quarts of whatever oil you want, and 1 quart of Lucas. Best way to do it is put in the 4 quarts first, start the car and let it idle up to temp. Then, while the engine is runnin at idle, slowly pour in the Lucas, allowing it to mix into your oil. After you puor it in, take it for a drive, drive nice and easy for a bit, allowing it to mix into your oil completely. After a while, you may motice it smokes less. It takes a day or two before you notice the improvement.

2. Or, just wait till you need to add a quart of oil, but use the Lucas instead of a quart of oil, do it the same way as mentioned, while idling, after it's warmed up.

Your other options are all much more expensive then a $9 quart of Lucas.

This stuff works pretty good on worn motors.

By the way, I would use it with just 10W30, don't wanna go to thick as this stuff thickens the oil a bit. And I would do it with an oil change at the same time, cause the way your car is runnig, you probably got some shitty lookin oil, might be bits of metaL in there.

If you try it post back let me know if it helped or not.


And by the way, if one quart helps al ittle you can go as far as substituting 2 quarts if you want to. This shit is thick, might help with the compreesion issue a bit.
 
thanx man! i think i'll try it , im running 5w20 right now i think? cant remember but it was a realy thick oil for old engines in its getting cold out ,im gonna see if enybody else has a compression tester i can barrow, the car starts up fine when i first start it up but after a while of running it in shut it off it wont start back up for a while, and at 75,0,0,40 do you eaven think that it would attemp to start up beause cars need the 4 basic things to run and thats spark,fuel,compression,and oil right
 
Wow that is really frign low. Umm well you could try it, in this case thicker might be better. I'd go with the thickest shit there is LOL.

5W30 is very thin by the way, not thick. 20W50 is thick.

In the winter you normally want thinner oil, but with this engine I'd put in thick oil and try the Lucas. 4 quarts of 20W50, and a Quart of lucas.

It'll probablt make a little difference. You could go with 3 quarts of oil and 2 Lucas. Depends on how cold it is. If really cold go with only 1 quart.

Or go with 3 quarts of 10W30, two quarts of Lucas. The lucas is kinda spendy, but it can help seal up those rings.
 
yea 20w50 is what i ment sorry but its eather 25w50 or that, im not sure i'll think i'll leave it in to see if it'a help my engine when it gets colder, whats the spec compression for a turbo and does enyone know what the allowance compression for them are
 
Check it out dude:

:laser: I'd throw a quart of the Lucas in there and see how it works. Drain a quart of oil out or do it when you are a quart low. You should add it with the car idling at normal running temp if you can.

Looks like your motor is pretty toasted, unless you did the compression test wrong. :(
 
Bad rings... ?

Smoke smell like burned engine oil? If yes, start saving your pennies. If it is an oil burning smell, try some Lucas oil stabilizer as a test. Did that help? If no, possibly (very remote) other problem than rings. If it did, it probably confirms the rings diagnosis.

Consider a compression test. Get it done by a compentent mechanic.
