- 190e/1993/2.3 8 valve
Hi guys,
I bought a 1993 2.3 L, 4 cylinder, 190e a few months back. It has 94k miles on the original motor. Since I owned it, it had an issue with starting when warm. Cold start is really fast generally. Yet the car drives really well once you get it started. Did a complete tune up, changed Oxygen sensor. Then I decided to do a compression test and a leak down test and surprisingly got these results:
1st cyl - 105 lbs; 25 % leak
2nd cyl - 80 lbs; 85 % leak
3rd cyl - 75 lbs; 85% leak
4th cyl - 50 lbs; 85% leak
How could this be possible, given the car runs so well? Some history on the car: owned by an old couple; always dealer-maintained, no major service done to it. It was stored in a barn for about 5 years, by their son, since they passed away. Any way there are just some stuck valves/rings that some good old additives can fix?! Or am I just being delusional here. Could this engine just crap out this soon (94k)?
It has poor idle. While driving however, cannot even tell that anything is wrong with it, other than a bit of loss of power up hills. Driving along the other day, pulled over to the side of the road to wait for my friend behind me (that is how well it drives! ) and the car crapped out. I got stuck there; it didn't want to restart. Even after 6 hours of waiting for it to cool (after the tow home), didn't want to start. Any thoughts would sure be appreciated.
