#107 of 400 Re: EGR Valve [paulcha]
Jul 03, 2005 (2:02 pm)
I hope someone can lead me in the right direction. Here is my problem I have a 1995 Chevy S-10 Blazer 4x4 it seems that my egr valve keeps getting clogged up with carbon I went ahead and took it off and cleaned it out but that only lasted a couple of weeks it's doing the same thing again I took it apart again and found more carbon they were almost like little rocks of carbon. I tried looking online for some help on cleaning out the egr and I guess the intake but not much help found can someone help me resolve this problem. Is there something I can buy to clean out the carbon and is there somewhere I can get directions on how to take apart the intake if I have to. Thank You for the help!!!!!!
#108 of 400 hard starting chevy S10 pickup
Jul 07, 2005 (7:37 am)
My chevy S10 pickup will become hard to start when the fuel level goes below about one-quarter of a tank. It starts well with a full tank. A local garage said their tests showed the computer to be at fault. I now have a new computer in the truck but it is still hard to start when the gas is low. Any suggestions?

If you don't have a manual, which you should have had b4 you took the heads off, get a manual. Don't rely on the parts store people, not trying to put anyone that works/worked at a parts store, but in most cases many are just working there to get a check. This will have a listing of torque specifications, tightening sequence, also will have pic of the wire routing. You seriously need the book and need to read it before you dive back in.
Second, you may have the distributor 180-out. I'm guessing you didn't bring #1 to TDC, mark the position of the rotor to the relation of the body before you took everything apart. Or just left the motor as is, mark the locations, pull the distributor straight out, left that alone, and put it back in? Did you at least mark the distributor where the wires went and how they were routed? One trick you can try, and it doesn't work all the time be may in this case, is to place the old distributor cap w/wires still connected (they're still connected right?), onto the distributor, and go one at a time, longest to short, and see where they fall. This could at least give you a guesstimate. Not sure distributor caps are marked anymore. Last ones I saw marked where the FOMOCOs, and that was LONG time ago. But again, get a manual!!
Tightening the rocker arms won't help on the compression, who told you that? Pull a Moe/Larry/Curly and give them a slap on the head and an eye-gouge. It'll help if you have pushrod noise, tightening a little can quiet a pushrod down. But in terms of raising compression, haven't heard that one before. Is the idea that the valve is staying open and by tightening/loosening the rocker the valve will move up/down and eventually stay close? If that's the case, then either the valve job was bad, the seats/valves are at a major mismatch,letting air/fuel mix just blow-by or the heads are junk. Assuming you had the valve job done due to excessive blow-by? Also, don't tighten too much or you will ruin the lifter and cam lobe in a hurry.
Sounds like you may have a ring problem. Do you hear air passing through anything or any openings? How's the cranking, strong? With those low compressions you're engine isn't going to start, period. I would want to pull those heads off, make sure they're flat, check the seat/bowl/valve areas for cracks or other damage, then re-torque them (correct procedure, sequence, torque spec.).
As a last resort, tow the Blazer to some that knows what they're doing and have them get it in running order. Or call them over. But in any even get a manual and read it.

Yeah, my 94 S10Blazer, 115,000 Tahoe LT 4.3 V6 Automatic is doing that exact same thing. I bout it 3 weeks ago and had barely put 1200 miles on it before it started. Yesterday i took it into a shop and they messed around with it for a couple hours looking at stuff. They had to drive it and They told me it was the Front Diff Assembly. They said the part for it was 412.00 and labor would be 500.
So, i'm hoping that they're wrong, i'm going to bring it to another mechanich tomarrow. You don't happen to know what it is do you?
#111 of 400 Bozie- S 10 Electrical problem's
Jul 15, 2005 (1:33 am)
Help me someone. This is posted on the open forum 7-14-05. But here goes again. My 87-Tahao S-10 has developed an electrical problem with the courtesy light's. Believe it or not I have exchange 5 batteries in the last 5-month's due to this problem. Walmart's and O'riely's have been kind in this matter but it was O'riely's that that convienced me that I had a drain instead of battery problem. Now I've traced the problem down to the area of the fuse block. Pull the fuse for the courtesy light's , they want go off, pull the fuse for the horn and they go off. These are 20-amp fuses's. The horn fuse is just above the courtesy light fuse. How difficult is it to drop the fuse assembly board? Also it it possiable that that is where the problem is? Thank's, Bozie

After turning key on to start, let all the buzzer's and horn's stop blowing and then try starting. Or like I do hit the starter for a few turn's and shut off then try again. Work's for me. Probably a weak elec. fuel pump. Bozie
#113 of 400 93 blazer s10 brake probs
Jul 18, 2005 (1:00 pm)
i have a prob with my brakes. It starts and drives fine but every once in awhile ill go to hit my brakes and they will be hard as a rock. i cant budge them at all. the abs light comes on when it hit 15 mph and turns off when i drop below that. and sometimes the brake light will come on as well. the code reads 38(wheel speed error) but i cant see how that would cause the pedal to lock up like that. the booster seems to work fine and the master still seems to be good. I would appreciate any insight anyone has on this since no mechanic i have talked with has ever dealt with something like this.

by brakes i mean just the pedal.
#115 of 400 87 S-10 Blazer tailgate won't open
Jul 20, 2005 (11:07 am)
I have a (new to me) 87 blazer and the tailgate lock does not open the tailgate itself. It will release the window and makes a clicking sound, but nothing.
Is there a way to open the tailgate manually? I would like to change out the lock and so on, but can't get to it.
Thanks for any help!!!
#116 of 400 Oil Pan cange S-10 4.3l
Jul 20, 2005 (12:55 pm)
I have a 1989 S-10 Blazer, 4.3L V6. I stripped the oil pan plug thread and thinking about replacing the oil pan. I looked under there and it seemed rather simple: take off the screws around it, pop it off, get new gasket, sealant, etc. However, on some Japanese cars I had to jack up the transmission, remove the support in order to get to the last 3 screws of the oil pan. That seems like a job for a mechanic. Please let me know what is involved.
