Ouch - I think you're dead on the mark with regards to the rings. If the motor got that hot, I surprized the head gaskets are still intact. You could use a ball hone to break the glaze on the cylinder bores and add a new set of rings...assuming that you want to go that far... It's also pretty realistic that the valve seals are failing as well. Does it smoke when you start it? I'm in the process of replacing the heads on my 383 smblk. It never overheated, but one cast iron head actually rotted thru and started leaking on number 5 cylinder last week. Bought a pair of Aluminum Perform RPM 64 cc'd heads \new RPM intake and am trashing the old castings - -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of I. M.

However, some of the recent answers started me wondering about the two Oldsmobiles I also own. Both are the "Y" type 307 CID engines. If anyone has owned one of these they know they run forever. These are everyday drivers. Anyway, in both cases, the engines started excessive oil burning after overheating. One blew a lower radiator hose and my son didn't shut it off until steam started coming out under the car. In the other case, I was cruising along the interstate and my temperature guage started climbing and ended up in the red zone. I shut it off when I noticed a leak in the thermostat gasket. I bought a couple gallons of Prestone which got me to my destination. Again, I stopped when the temp climbed into the red area and added 50:50 antifreeze to the overfill tank. My conclusion was that the rings were shot so I just keep putting oil in as required. Before these disasters, I could go 2000 miles without adding oil. Now it is a quart every 300 to 500 miles depending upon the type of driving. Does anyone think that this could be something as simple as worn valve seals? If so, is there any way to inspect them or check them without removing the springs? >From: "nick visciani" <[EMAIL PROTECTED]> >Reply-To: [EMAIL PROTECTED] >To: <[EMAIL PROTECTED]> >Subject: RE: [Chevelle-List] oil consumpsion >Date: Tue, 15 Jan 2002 12:33:31 -0500 > > >Replies to this message are sent to The Chevelle Mailing List >------------------------------------------------------------ > >Hey Brian - >Yup, I believe Fel-Pro or Sealed-Power has them.
