Hello, I live in Owensboro, KY and looking to have my 87 GN engine completely redone and can't find anyone in this area that's familiar with these cars and I don't want just anyone working on it! I just purchased the car with 59K actual miles and was told it had an ignition problem and didn't get to hear it run before I bought it. I have since gotten it cranked and it's pouring blue smoke from the valve covers and out the exhaust! The previous owner stated to me that it was pushing 25LBS of boost before and I thought he was full of it but I guess that's what happened to the engine! The motor has never been worked on and I'm just looking to do a basic rebuild close to factory and was hoping someone on here could point me in the right direction and tell me where I can take the car. I'm willing to travel a few hundred miles to insure it's in the right hands so any info will be greatly appreciated! Thanks for your time and help!!!
Please help point me in the right direction!

Welcome Pilgrim! You came to the right place for help. First check your oil for contamination due to water/coolant in the oil pan. commonly called "a milk-shake". If so, damage to bearings, etc. would have most likely be a result if run under that condition. The blue smoke may be nothing more than the turbo seals gone and the oil is getting into the exhaust down pipe. Bad valve seals would allow for oil getting into the cylinder/s. Boost above 16#s would require racegas or alchy. Does the car have an alchy kit on it? If you run out of alchy or fail to prime the alchy pump prior to high boost, it will eventually blow a head-gasket. It can blow between cylinders or into the valley area and it is more difficult to detect. You can check for bubbles in the radiator. A compression and leak down test can reveal problems. All the cylinders should be at least w/in 10% of each other w/a minimum of 135psi. Some are running lower, in the 120's, but it's a personal preferance.
It would be great if you can list the mod's and more help wil be on the way. No sense in tearing it down if it is not nescessary. H/gaskets are a common sacrifice to save major components. Spend a lot of time reading and asking questions and you will be a "happy owner" like the rest of us that are still hanging in!
