Subject: [1992 LT1/MN6] My Engine is dying... by bogus on 2007/10/26 3:25:50 after 164k miles... I think it's on it's last legs. I have more diags to perform, but I am of the mindset to replace the long block and move on. Here are the issue: 1. There is a bit of a random miss. 2. The engine is eating coolant. I have a new DeWitts aluminum radiator in there and there are no leaks anywhere. If the waterpump was leaking, I would expect there to be a belt slippage issue, and there isn't. I just topped it off, and I was down 1/2 gallon in the surge tank. This is happening about every 4~6 weeks. 3. My own stupidity. Three years ago, I beleived Tom at Carolina Clutches that the Fidenza doesn't need to be match balanced. Was I ever wrong. I have a vibration that starts at about 4000 RPM and gets worse... I give up at 4300... It's that bad. I have found a 1992 LT1 long block at www.vette2vette.com. It's got low miles, 25k, for $1500. It's got the dual mass flywheel attached, so worst case, I get the flywheels match balanced. My current clutch is 40k miles old, so the pressure plate should be ok, and I can replace the insert on the Fidenza. The motor is from a theft recovery, and was stripped of it's accessories before recovery. The engine has been properly pickled since removal about 2 years ago. I might have some room on the engine, money wise. I am going to counter offer on it. Mainly, $1500 and include shipping... I am also thinking of doing roller rockers... or maybe just getting a hot cam kit... for $570 at Summit, it sure is a deal. Any better deals on that? Thoughts, gang? Thanks! :thumbright: |
