I am very pleased to announce that the shop that told me that my engine
was shot at 133k miles was full of shit. I took my car in to an auto
electric shop to see why my knock sensor and atmospheric pressure sensor
kept triggering ECU error codes. Thay told me that my car had terrible
blow-by and that one cylinder was down 40psi from the other three. They
said that pressure in the crankcase was causing all my problems. I was
devastated. Even though I own spare EJ22T and EJ20G engines, it is a
matter of personal pride for me to get maximum life out of any engine
that I am currently abusing. My car has never used a drop of oil and it
has never given a puff of smoke, even on start-up. I just couldn't
accept their grim prognosis. I took it in to another shop for a leak
down test and they told me that it has 150lbs compression on all four,
with two showing 5% leak down and two showing 10% leak down. I believe
that is pretty damn good. Does anyone else have any compression and/or
leak down data to share for perspective?
The guy at TuneTech suggested that my knock sensor errors are caused by
carbon bbuild-up and that I should get the engine warmed up and allow it
to drink one cup of cold water through a vacuum line that will feed all
four cylinders. He mentioned some miracle tiger-pee-in-a-can called Sea
Foam, but he said that straight water does the trick. It is important
to keep the revs up so as not to kill the engine. Does anyone else have
any experience with decarbonizing procedures?
TuneTech also said that my pressure control solenoid valve might be
causing my atmospheric pressure sensor errors.

Good Leak Down Test
Bill, Although I have yet to have a compression test done, my Leakdown test
with around 124,000 miles were about 4 percent in three cylinders and around
5-6 percent in the other one, so yours aren't too far off. I have also seen
these numbers come down after people use some kind of "carbon cleaner" or
the water trick as you described. I suppose it lets the rings and valves do
a better job of sealing after the built-up carbon is off. I would surely
test it again after you are done with the cleaning and see if it changes
any. Mopar Combustion Chamber Cleaner is supposed to work wonders as well.
There's just something about letting the motor ingest water that gives me
the creeps

Good Leak Down Test
I had my 90 leg test a year ago and all were in the 185psi compression
range.

Good Leak Down Test
Hi-just went through the same thing today (3 cyls @ 155 & 1 supposedly @
118)-I understand devastated! Out of curiosity, was the `low` cyl the one by
the brake booster? Could it be that cyl is the hardest to get an accurate
reading? After a leak-down test of that cyl, no noticeable air past valves
or rings; motor never burns or uses oil between changes every 3k miles-I`m
perplexed! A related question-anyone every done a valve job & found worn cam
lobes or followers @ 144k +? Any related experience with upgrading cams on a
N/A 2.2? Anxiously awaiting answers!-ROD
