I have a 2005 Astro , the latch broke with the rear doors closed. How can I get the inside door panels off when I can't get access to some of the screws that hold it on?
Is there a way to jimmy the door open? Thanks for any help!

Ticking/Knocking noise

Our 1999 GMC Safari that has 125,000 developed a ticking/knocking noise on the right side of the engine. I have had some people tell me that it sounds light a collapsed lifter. The runs fine except for this noise. I put in some mystery oil from and the noise is not as nocticable now but I can still hear it. Now when ever I changed the oil, if I do not put a QT of mystery oil in the crack case, the noise come back but after the mystery oil is substituted for 1 QT of engine oil, the noise dies down but you can still faintly hear it. Has anyone else had this problem and is it really a collapsed lifter?

Same thing happened to me. Cheap pot metal latch. Anyway, just bust off any left on the handle until its all gone. Just the piece that moves, not the body. Look in there, and the latch is pointed at the 10-11 O'Clock position.. Doors unlocked, just screwdriver it over to the 1-2 o'clock and it will pop open. You have a 4 screw panel in the side of the door. Take that off so you can see what your doing. What I did it just drill a 1/4" hole in the latch, and ran a bolt through it sticking out the back, to lever the door open. Had to elongate the plate (drill/Dremel/whatever), to get a full swing on the bolt. Worked for years now. The lock is separate, so even like this, no one can break in. Hope this helps. Be gentle with the other latches too. Had to replace the drivers door, and a real pain. Go to a junk yard if ya want, and you will see more. Maybe pick up one now for a spare, as Astros last a long time.

Try a full oil change/filter. Then instead of 5 qts oil, do 4, and get a qt of Risone in there. Comes in a yellow bottle. Run it for 1000, won't hurt anything, might bust up the sludge in the lifter, which is probably whats hanging up.

Perhaps your GM 4.3L engine has Piston Slap? Piston Slap is common on many GM engines. Especially the 4.3.
My 2001 Safari 4.3L has piston slap in really cold weather. Especially during its warm up phase. For more details, surf: http://www.pistonslap.com/photos.htm
For me, I get my local auto shop to install Synthetic "5-w30" during colder weather. In the summer hotter months, use normal Synthetic 10w-30 oil. This seems to help reduce engine noise...
Hope this helps...

The best way to determine a noise is use a automotive stethoscope because a knocking noise you think may be coming from one place will actually resonate from any where,and a stethoscope is the best way to find out.The 350 chevy engine has a push rod driven fuel pump and it's hard to tell how many people that's been charged for lifter replacement that didn't help the problem because it sounds just like a lifter and it's just a worn fuel pump spring or worn push rod.

First, its a 4.3, V6, not a 350 V8. And had many, with never a pump rod go bad. Thing is, the fuel pump is in the tank, electric. And getting a "ear piece scope" in there is very difficult. If its a half speed always "tick", its a lifter. Piston slap will be engine speed, and a slap on the throttle, will increase it. Pretty simple. 50 years Chevy, 175000 my Astro...do what I said..Rislone...or just live with it until the cam gets "wiped", which is many years. Lose a little perfomance, but not worth any major engine work...
