Angry Low Compression On #3

Had a code P0303 and took car to the dealer for check. The guy came back and told me I needed a new engine. Runs great but has a rough idle. Did my own compression check and got 190 on all but #3. It ran 90 dry and 150 wet. My question is can I keep driving until the spring when the weather permits a driveway ring job. Right now I'm flushing this puppy out and putting in some synthetic to keep the wear where it is right now and avoid any new problems. 85k is too young for this sh-----. Any ideas, any body.

Well, I definitely think you are right on the money with the ring job and yea, you can drive the car and just get used to the shittiness and then re-ring when you have the time/space. Unfortunately, sometimes these things happen in the worst times, but oh well.

Yep its a 2.7 and now I found peanut butter in the coolant. Whats the chance that I can be lucky enough to just have a blown head gasket? could the wet and dry compression test (90 dry and 150) wet mean just the head gasket?

It could be just the headgasket, but if you may recall, the 2.7's have an oil sludge problem and looks like you found it. Luckily, you found it before it's too late and the engine's dead, so now would be as good a time as any to have your oiling system flushed with a machine (I personally like Pep Boys' Bilstein oil flush service) and then inspect other parts. The compression leak could be the headgasket, definitely.

Thanks, there's a pep boys near the house and that's probably better that what I was going to do. (flush in a can type stuff and then change the oil). Have you seen anybody take the heads off this motor in place? I'm an old chevy small block guy with no overhead cam experience. Anything thats not in the Haynes book I should look out for?

You can take off the heads with the engine in the car (at least I think). I only know this because I have seen pics with the heads off the engine while it is still in the car. I haven't done it myself.

After you do an oil flush put a liter of Lucas Oil stabilizer in. I have a bad ring in my 5.0, getting blow by out of the oil fill cap. I put some lucas in and it cut the blow by shooting out of the oil fill cap by more than half.

Funny you should mention that, I had blow-by so bad that it actually pushed the vacuum hose out of the breather elbow on the passenger valve cover (PCV is in the driver's cover). What I did to fix that problem was take off every single vacuum hose and clean it out real good and man, I found so much gunk in there that I had to push really really hard with a coat hanger to poke through it, so no wonder it kept coming out. Of course, it only dawned on me to do that after I had tightened the grommet and elbow so tight that the oil blew out of the dipstick tube, yes, even after it shot the dipstick up enough that I got a huge oil stain on my hood padding. You might want to try that before you find time and money for a re-ringing. Oh, and speaking of SBC experience, thought I'd throw in a pic of the car I'm currently losing my hair over.

Funny thing is i think i have about 3 or 4 vacuum lines on my car. Lets see, one for the brake booster, one for my vacuum advance, and one for my PCV valve. Its not burning any oil though. And yesturday i was changing the thermostat gasket and I stripped the threads out of the thermostat holes on the intake. Doh. Helicoil time. Or maybe...weiland stealth intake manifold time...weeeeeee.
