1986 GN with salvage title (due to theft, I believe) Hard top Pretty clean interior except for the lower part of the driver's seat which is torn (even the headliner is still intact) Approx 120K on the chassis Only has moderate body damage where the front of the driver's door meets...

I'm about to install a camshaft in a motor I'm rebuilding and although this might be a stupid question, I'd like to know if degreeing it is really necessary. I've replaced camshafts in several different motors over the years and have always just lined up the dots on the timing gears and have...

Probably a dumb question but does anybody know where I can buy a new one? I'm in the process of putting my motor back together and as I install each additional piston it's becoming increasingly difficult to keep turning it over to make sure the pistons aren't binding up. Thanks in...

I just bought these on March 11th but decided that I want to go with the ET Street Radials instead: Mickey Thompson Performance Tires & Wheels They're the 17" size (26X11.50-17LT to be exact) and only have 6 passes on them (all from last week at Infineon Raceway). I paid just under...

A guy here locally is selling a used GN motor for $1500 complete with everything (turbo, brackets, alternator etc.). He said that it only has 50K miles and can prove it, but since it's currently not in the car I'm not sure how he'd be able to do that. Even if he can't though, does this...

I've never had a GN motor rebuilt before so I'm not sure if it sounded reasonable or not. Please freel free to chime in with any and all opinions. Thanks, Christopher

After changing a timing chain, how long do you need to prime it for? What happened with mine is that I used a priming tool but only for about 30 seconds as once I saw about 40psi on my gauge I figured that was all it needed. After putting the cam sensor back in and firing it up, the oil...

After just having finished replacing my timing chain, I was trying to prime the oil pump but something very strange is happening. For some unknown reason, the oil pump shaft appears to be binding up somehow. While using a drill and priming tool, I originally thought that I just didn't...

I found a rebuilt GN long block for sale for a $1000 and was curious as to whether this was a kicka** deal or only just so-so. The story behind the engine is that the guy "inherited" it from a friend of his who owed him some money so he's just trying to recoup some of that back. The...

I have a question about replacing the rear main seal and although I know I'll probably get a lot of responses along the lines of "if you've already dropped the oil pan then just go ahead and replace it", I'm going to ask it anyway. ;) As mentioned, I do have the oil pan off as I had to...

While fixing my timing chain issue (link shown below) I decided to drop my oil pan and clean out the chunks of nylon in the pickup (yes, there were lots). http://www.turbobuick.com/forums/engine-tech/240599-changing-my-timing-chain-does-look-like-normal-wear-tear.html Since I have a slight...

I just pulled off the front timing cover and removed my timing chain to fix the no-start problem I had a couple of weeks back. Here's what my timing gear looked like alongside a brand new one: My concern is whether this is considered "normal" wear and tear for a worn out timing...

My car died last week and wouldn't start again but I *thought* I had solved the problem tonight. I changed the crank sensor and went through all the tests in the "No Start" tree to verify that it should have in fact started up: - I had good fuel pressure - I changed the crank sensor and...

I'm still in the process of trying to diagnose the no-start problem with my 87 GN from last Monday and despite trying virtually everything suggested, I still can't get it to start. I just pulled the cap from the cam sensor to verify that it was turning while the motor was cranking and noticed...

I was just in the process of taking my son home and my 87 GN quit running all of a sudden. The car's got 110K miles on it and although the motor needs rebuilding (it has a rod knock when it's cold) the car's been running great up until now. What happened was that I was doing about 30mph...

After a long hiatus from the GN community, I’m just starting to build two project cars (86 & 87) that I purchased recently. The primary reason for this thread is to determine whether purchasing an aftermarket system like DFI, XFI or BS3 falls into the category of nice to have or need to have...

I can't pull it and replace just the parts that are needed? I know some people might accuse me of trying to be cheap, but since I've got two engines that need to be done, I wanted to do a basic rebuild on what will be the daily driver and then splurge on what will eventually become the track...

I recently rejoined the ranks of GN owner with the purchase of two project cars. I'm not sure of the gear ratio that I have but I'm curious as to how fast the engine should be turning while I'm on the freeway doing 65. I just checked while coming home and saw that it showed around 2600...

I've loosened the 12 bolts but still have the bumpers attached. Using a piece of wood and my floor jack I've tried lifting the body up a little from a few different places around the car but every time the frame also lifts up too. All the bolts came loose quite easily (it's a CA car) but I'm...
