I have a 1997, 3500 with 412+000 miles on it and the intake manifold gaskets were leaking. Replacing them did the trick but while all of that was apart I also had the fuel pressure regulator replaced also. It's alot easier to do it now than later since it is located inside the intake manifold. If you've noticed it takes a few more cranks for the engine to start that's usually the problem.

I saw your post about replacing the intake gaskets on your 99 Chevy Express. I have a leak and wasn't sure if the intake gasket is the gasket between the water pump and the engine? Please confirm. Thanks.
#38 of 92 intake gasket

the intake gasket is two large peices and two small bridges. The intake is the peice that is directly in the center top of teh engine. On a 99 the tbi bolts to it. The end gaskets are just rubber bridges that most mechanics never use. Most used permatex instead as a bead along the top of the engine block. I use "the right stuff"
The side (actual intake gasket) sits on the cylinder heads on each side, the intake bolts down to the heads with the bridge of the block itself in the middle at teh front and back about 7 inches across.
An intake gasket leak would be rare, and might be possle to fix just by tightening the intake down a bit. Most common is an oil leak from the back along the bridge area. I think the information regarding the fp regulator being in the intake is incorrect. Most are on the the intake, but on a tbi injected 99 model I dont think its even near the tb. It ma even be regulated in the tank.
The gaskets are about 20-30$.......and it would take awhile to do. In my van I have to remove the front seats just to get the dog house off.......

This will sound over simplisticbut double check your fuses there is one that says brake,. and one on the bottom that says stop.
#40 of 92 disc brake conversion
Apr 17, 2009 (2:26 pm)
I have a 1999 gmc savana conversion van that I would like to convert the rear brakes to disc, it has 11in drums currently. does anyone know of a kit that will convert without mods??

most of the stopping power is on the front. Itmat serve you much better to do the front first. There are many options, I know there is a 14 inch rotor kit for about 650$ that goes on the front. This will substantially improve braking. Drums actually work very well (even better then discs) when only used once. For one stop drums are fine. For repeated stops, racing, trying to slow a heavy load going down a hill is where drums fade, and discs shine.
you do need atleast 18 wheels to clear the large rotors. I scored a bear brake systems aluma brake system from a guy with a denali trading it in. The bear system is (4) 14 inch rotors with 4 piston calipers, I ve never been into brakle systems....I build power for going fast. So far the bears have saved it twice from accidents....and the stopping is incredible. I run 20 inch wheel with 275 tires too.

What year was the denali & did the rear disc work without any mods?
#43 of 92 Electrical problem
Jun 15, 2009 (5:24 pm)
I have a 2002 Savana 3500 cutaway box truck with 5.7 L gas. The other day I noticed my speedometer seemed to be hanging up and not working correctly. When I got out of the truck with it still running my daytime running lights(which in 2002 is still part of the headlights) were alternating like an emergency vehicle. When I turned the actual headlights on at the switch the alternating stopped but when switch was turned off they started alternating again. This has happened only one time since but both times it involved the same symptoms with the speedometer acting up and the drl's alternating. Anyone have any ideas?

Mar 29, 2010 (6:04 pm)
Our 2005 Forrest River motor home has this same symptom. My mechanic said it sounds like over heating but I never ride the brakes and 99% there is no sign of vibration. It only shows up when you need good braking the most, going down steep passes even if I'm crawling. I have had the brake lines replaced because they collapsed and the antilock brake control board has been replaced. These repairs had no effect on this problem.
#45 of 92 brake shudder in rear
Sep 07, 2010 (3:20 am)
I have a 2000 chevy express that has developed a shudder in the rear brakes. At a low speed the brakes will grab very hard causing a shudder in the rear end. It does not do it when stopping from a high speed just as you creep thru a parking lot at low speeds. The only way to stop it for a time is to drive in reverse and let them adjust themselves. I have replaced the rear shoes and installed new hardware kits. Still same problem. This van is used as a taxi and all 3 of us in the shop are stumped. Anyone have an answer for us?
