I switched back to ceramic coated stock headers. These are in decent condition and didn't leak when I pulled them off. The turbo flange has been resurfaced within the last couple years. Asking $400 but will entertain all reasonable offers. I'm located in the Everett area, just a few minutes from...

call me stupid....so that paper thin gasket between the oil pump and filter housing. i used i very thin layer of gasket maker on either side of that. I just read somewhere that is kinda a no-no? i didn't pack it with Vaseline either. all i was going in there to do was replace that gasket. also...

ok so here i am again. pulled the timing chain cover off and replaced the timing chain. i turned it over a couple times by hand to get to TDC. So my question is what do I have to do to get the cam position sensor set? I pulled the whole sensor out of the cover and put it back exactly where it...

I looked around couldn't find anything about this. What is the torque on the head bolts? I have ARP head bolts that I just got. I believe they are torque to yield? so I should have a torque number then how much farther do I need to go for the yield part? and what is the sequence? do I start in...

stock cast iron heads off of my 87 GN. If I where to have a valve job done what kind of angle would you guys recommend or would you even bother with doing a valve job? thanks

what do you guys recommend for headers? I have ATR on the car and they suck big time! had to take them off 3 times to get welded cause they keep cracking and the up pipe surface is not flat so it leaks out of there. Has anybody used these: 1986 1987 BUICK GRAND NATIONAL V6 GN STAINLESS...

1987 GN. has coolant coming out of headers. I did a compression check with all plugs out. 1,3,5 120,120,120 2,4,6 119, 115, 112. seems ok to me? (im at 6,200ft elevation) also did a cooling system pressure test held 16psi. started it up let it run and it built cooling system pressure like it is...

Ok so here is the story...my GN has sat in the garage for the better part of the last 4 years. I drove it about 2 months ago and parked it again. was doing some work on the turbo and getting it ready to drive. I was toping off all the fluids when i noticed the coolant was about 6" low in the...

Hey All, My brother had a little remote start/shifter linkage malfunction a couple weeks ago that resulted in my GN starting in gear and bumping into a suburban. I need a new bumper/header panel/driver side fender/headlight assembly etc. I've tried contacting some of the posters of the "parts...

Anyone run the Competition Engineering Adjustable Shocks? CE Shocks I'm sure they work fine for the 1/4, but would they be drivable on the street?

I'm trying to find a replacement for my piece of junk ATR wastegate. Can anyone tell me the pro's/con's of the Tial 38mm/Deltagate II/Deltagate evolution? Will they all be a bolt-on replacement onto my ATR headers? Thanks:biggrin:

I'm going to start collecting parts for a hydroboost/ABS conversion, and I'm trying to figure out how much of a project it's going to be. Also, does anyone know if the ABS pump on the Astros is separate from the master cylinder? Will any Astro hydroboost master cylinder work? Thoughts...

My car recently started miss-firing and sputtering. It started happening intermittently under moderate (but not high) boost, and now happens at anything over a 1.2-1.4 TPS voltage. It pops, seems to backfire, and misses badly. Pulling it down a gear usually helps a bit to smooth it out, and it...

So I'm installing a rally pack in my slow car (speedo/tach/guages) and I need to get it in fully working order before I install it. Anyone know of a local place that does speedo/tach calibration/re-calibration? Odometer repair? :confused:

So I'm looking at getting a set of 17X8 rims with 4.5" backspacing for my GN. Does anybody know if I'll run into problems with those on the front with a 255-45-R17 tire? (it's the same diameter as a 215-65-R15 . . .what's on there now).

I'm looking for a set of widened (less than 10") stock GN wheels. I could get them made for around $200 a wheel but that seems pretty steep for what I want to do. I'd prefer less-than-perfect used wheels since it's a driver, not a show car. Anybody have ideas?

So I'm looking into upgrading my ECM. I started out looking at programmable boost controllers and came across this: e-boost2 but was told by a friend that that's close to the price of a low end engine management system. In my search for a programmable engine management/boost controller I came...

So I was looking at the new Challenger concept and had a thought. When they designed the Challenger they actually took a 1970 Challenger into to design studio, and I think the result is faithful to the original. And IMO far and away the best looking new car in the last 10-15 years...

I'm looking for a good high quality image of a GN to frame and hang on my living room wall. Something 24X30 or so would be nice. Anybody know where I could find that? Painting or photograph doesn't really matter. . .
