A conundrum if you will - Let's say you have a car with 'low compression'
I did, about 60k miles ago. Way back when at 200k miles. It measured about 50-80 per cylinder (except for the burnt valve on a dead cylinder- that was a "zero")
Mechanic said... "It's dead Jim...."
So I drove it home (cause thats how I roll
). Coming home over the mountain, I noticed a pickup truck ahead of me blowing all sorts of smoke and stuff.
I wasn't.
"Hmmm...." I thought. Got home, pulled the head, found the burnt valve, and the cylinder walls had original honing marks from when they were made.
Hmmmm.... How would a car with no compression have zero wear on the cylinder walls?
My working theory was - "perhaps the rings never even seated"
So I fixed the valve, and enjoyed the car another 60k miles. Now 260K miles
In yo' face mechanic
NOW.....
I can't get good PCV suction in the engine. Just redid the system. There WERE some leaks in the system- but- Engine runs worse. than before I redid the system.
Still no suction.
Perhaps the rings are worn out? Perhaps I did something wrong?
On one hand, the compression test from long ago sucked, but... the car has some variable timing which might affect compression, or maybe compression is compression-
But... there's not one bit of oil or debri or crap on the rear of the car which all my other cars had when the engines really did wear out. No oil plumes or friends laughing at me. My long since gone 944 literally shat oil on a coworker when I started it once and she was walking behind it- that's a
bad sign.
No signs of a rear end nature here.
No "Colon Blow"
What gives?
