Has anyone found a tool that helps in changing the distributor cap, or any other easy way to change the cap for that matter? I have a 1998 Sierra 3500 Dually 4wd. Last time I changed the distributor cap and rotor it was an 8 - 10 hour thing, because the cap is under the intake manifold so it is very difficult to tighten one of the cap's screws. |

Replying to: noobie1 (Nov 30, 2005 9:32 am) I finally found something to post on here. The "piston slap" issue is really a load of crap. Dealers say it does it on start up and goes away, but I have noticed while driving the valves rattle like you have bad gas. The knocking you hear is more than likely the roller lifters with no oil at start up. The excuse piston slap is used is how the design of the engine and where the lifters are placed in the engine. They are held in place with in a grouping of 4 in a container that is bolted to the block. Due to the design the opening is large enough to amplify any engine noise near the pistons and the heads are bolted directly on top of the lifter gallies making it difficult to make this repair. I pulled the valve cover and ran the motor with little or no oil coming thru the pushrods on the lifters. I also have found out that the oil pumps can fail with no warning and have ran as low as 6psi at idle which the dealer says is normal. I am in the process of replacing the oil pump and lifters and hopefully will remedy my situation. It has not burned oil, like I have read on sites where 2-4 quarts of oil between oil changes is normal by dealer or GM customer service standards but it is not normal, I have had several GM's in the past and 1 quart or less in 3-5k was normal. I really love my truck and yes GM has got problems but they better get their stuff together and take care of the customer instead of being in denial or they will not have customers. |

I have a 2002 GMC Denali PU 6.0L W/Quad Steering. Between 30-40MPH I experience a vibration noice (sounds like a heat shield vibrating maybe) When the vibration begins and I hold my speed steady, the vibration will not go away. I do not lose power or feel any change in vehicle handling. It is just anoying. Does anybody have any clues

Replying to: jf3761 (Jun 20, 2006 5:49 pm) and your truck is a 02 I am betting on a loose heat sheild on your cat(s). Those cheap spot welds just break/rust off thus causing the vibration(s). Try driving a few wood wedges between the cat and muffler and see if it cures your problem.

Guys: My father has an 2000' model GMC Sierra with a 5.3L/V8 Vortec Engine. Nice truck with somewhere in the neighborhood of 35,000miles. Lately his blower motor is very loud when using the heater/ac/vent. I told him I would write on here and see if any one had any ideas of why this is. Just the blower motor going bad? or can something else cause this? Thanks guys, kimble989 |

What is the correct placement for the alternator brackets on a 1989 GMC Sierra? I'm rebuilding my engine and can't figure out how to put the brackets on correctly. Any help (pictures especially) would be appreciated. Thanks, -Rich |

Ok, this is a 99 v6 4x4 sierra 1500. The check engine light was on so it was taken to a garage and hooked up to the computer. They said that there was a bad o2 sensor and the computer said the transmission was slipping. We told them that it was surprising since there was nothing noticeable with the transmission. The garage then said to change the transmission (oh, this is an automatic transmission) fluid and filter. Then they would check the computer again. Well, now it noticeably slips.....badly. Even re did everything to make sure something wasn't loose or there was enough fluid. Everything looks fine, but the slipping is horrible. Any ideas? Not sure if anyone can really help but transmission work is so pricey. I'm sure we are gonna have to bite the bullet and spend a good bit of money but I wanted to see if any of you had any problems similar. Thanks to all in advance. J
