I recommend turning off your CAPS LOCK. People tend to ignore messages typed in ALL CAPS.

Hi all,
I have had my 1990 5.7L Blazer for 17 years and I finally need to change the motor. I am considering trying to convert it to a diesel. Any pointers or show stoppers?

HELP!!!! clunk in front end HELP!!!!!!!

I just bought a 2001 gmc jimmy. Has 100,000 miles. Bought it thinking the clunk was the ball joints or a loose/worn out shock. NOPE!!!! Replaced the ball joints with "Moog" brand. The clunk is only there when you go over bumps that resemble something like going over a set of train tracks. The truck has been to (3) GMC dealers, and (3) high end mechanic shops. NO one can figure out where the clunk is comming from. Trust me.... this thing has been pried, rocked, shook, climbed over, and under, and every part has been grabbed and shook to see what is loose or out of place. NOTHING!!!!!!!! However everyone says that as bad as the clunk is... we should be able to see the damage of what is broken....but we cant find it.....
PLEASE can anyone give some advice of where to look? Could there be a spacer or rubber bushing that is still in place, but worn out? I dont just want to start ripping stuff apart "hoping" it does the trick.

With that many miles the idler arm should have been changed by now. When worn, it makes a really loud clunk going over bumps. My favorite test is to find a road with the little reflector "bumps" down the stripe. Drive down the stripe with the wheels hitting the little bumps and a worn idler arm will really sound off. It doesn't take a lot of play in an idler to create a loud clunk. The driver can usually feel it in the steering wheel also.
About a $50 part, takes about 20 minutes to install, will need a puller to separate the center link from the idler.

I have a jimmy too and it dose that but mine is a loud pop like some thing just Brooke but it only do that when I am backing out my driveway and the wheel role off the sidewalk, one day I let my wife drive it up the sidewalk and I lay flat on my stomach and I saw what made the pop sound it was the tie rod ends I change all of them and the drag link too no more popping sound, but bear in mind that if you are going over a bump with the steering turned all the way there will be a loud clank which dose not mean anything is wrong it's just the way most GM trucks are it's the coil spring that snaps back into position from turning, but any other noise other than turning must be taken seriously.
Hope I was of help.

That sounds great if thats what it is!!!! Question: When I remove the idler arm, is it under force? Do you have to worry about it flying apart? OR is is as simple as you are describing.....just have a puller to seperate the part, and throw the other in, then tighten it up? Sounds simple enough if thats correct!!!!

Thank you for the reply, but it is more along the lines of the other reply to my post. Happens when you go down a "washboard" style dirt road. Im going to put in the idler arm like the other reply said, and prey it stops the clunk. Buying a new to me vehicle is never any fun.....I also found missing bolts(on the oil pan) while I was looking for this clunk. Geese I wonder who was the master mechanic who did that?

Nah, no springs to fly or anything like that. The shaft of the idler arm is tapered where it goes through the center link, so when tightened up it becomes a "press fit". A simple puller will separate the parts easily.
