    I found some parts on obstruckparts.org. Is this a legitimate site?

    Knocking

    My ‘98 factory 5.7 makes a knocking sound after a cold start. I do have a good bit of engine experience but I haven’t come across anything quite like this. It starts the knock about 3-4 seconds after the start and continues for about 20 seconds then goes away. It doesn’t seem like a lifter...

    Tight budget performance mods. What do you think?

    My 98 has the stock L31 with 162,000 mi and in excellent shape. Uses no oil; had mobil 1 most of its life and compression test is great. I’m thinking about upgrading to the newer spider, 0411, lightly ported heads w good springs and more lift capacity (heads are done) and a Bullett recommended...

    Need help with steering wheel airbag.

    I’m having a problem trying to remove the steering wheel airbag on my ‘98 1500. I’ve seen YouTube videos and I have service manuals for the ‘96 model year but I can’t find the right technique for releasing the springs from the retainers. Is the 96 the same? Videos only say how to do it but for...

    WTB hood.

    I need a good stock hood for my ‘98 GMT. I’m sure I can find one at a salvage yard but I’d rather someone on this forum be able to benefit from a sale. I’m willing to travel within 100 miles of the Memphis, Tn area. I’m sure shipping is prohibitive considering how inexpensive a used hood should be.

    Turning and Handling

    I looked but didn’t see a post on this. Please forgive me if I missed it but I have a 98 rcsb that i need to do some front suspension repair. Is there a rack and pinion setup available for this truck? I would like to do that to get better handling if possible. Thanks.

    Knock after startup

    I hope I’m not dragging up something that’s been discussed and worn out. If so I’m sorry. My 1998 5.7 has 162,000 mi and runs great. During it’s life it has had a valve job while it was in for intake gasket replacement. Very early in its life it developed a knock or tapping sound after a cold...

    1998 Chevy Silverado Repair and Restore

    This is my new-to-me 1998 Silverado rcsb that I obtained from a friend. I was actually with him when he bought the truck new so I know everything about it. It has 158,00 well-maintained miles. When I took possession it had a disintegrated dash, non-working stop lamps, worn carpet and broken air...
