1987 R10 Silverado 2wd

Here is a picture of the part the lines connect to, I will try to trace them down tomorrow in the daylight or next week when I get off work.  Hopefully I can get up tomorrow evening before work and trace it down and get it ordered so I can replace it next week when I get off work.

Those are brake lines connected to the brake combination valve.  Are you sure the fluid leak is from the valve or its lines?  That fluid color looks more like power steering fluid than brake fluid.  What color is the fluid in the brake master cylinder?  Check the front pump seal, the reservoir and the hoses for a power steering fluid leak.

Yea it is red fluid and the PS is what I have had to fill the past two days, I just noticed the cap is busted on the corner and I can pull up on it and pop the cap off without unscrewing it.  I washed all the parts that had the fluid on them down tonight and will try to pick up a new cap before driving it and see if that is the problem.





-- After installing the new ignition coil today the truck runs very good, hoping its just the cap and I can start working on the rest of the problem areas and start driving it around for errands.  I set the idle with the IAC on it but have one coming from rock auto as well, it was idled about a 1/8 turn low going from my ears and listening how it would run.....don't have an rpm gauge.  I idled it in Park just where it would idle and not die, if I turn the idle screw back maybe an 1/8 it would start to bog down a little and want to die.

I bet one of the rubber lines for the steering(most likely pressure side) has developed a pinhole leak, and it just happens to be hitting the brake combination valve. The cap may have a little fluid push past it, but nothing like what you are saying.

I can swap that out next week as precaution too, its also cheap.

I finally got some help from my brother on checking the lines today, had him move wheels one side to the other and you were correct when he got to the farthest amount of travel there was a pin hole shooting fluid from the pressure line.

Changed it out today and the leak seems to have gone away, the line they had on there was badly bent at the pump as well.  I thought I had gotten the wrong line until I saw that the last one to install it had bent the line into a box shape instead of how it comes in a U shape.

New IAC Valve came in today from Rock Auto, got it put on and reset.  Going to get a polishing wheel from harbor freight next week and try to get these factory wheels polished up and see if I want to keep them or look for some 18's or 20's instead of the 22's.  Prefer a wheel like the American Racing Nova Chrome or something similar, just need to find out what size and backspacing I can run with a 2-3" drop spindle.

New headliner installed today, we have an auto upholstery store here local and I picked up 10 yards of house brand headliner material and 2 cans of adhesive spray for $70. Was cheaper to buy 10 yards of house material than buy the name brand by the yard for the 3.5 yards I wanted.  Tomorrow I plan to pull the dash out and attempt to repair the cracks and spray paint it black with the krylon fusion paint.  Have had really good results with it on motorcycle fairings.

Ordered my lowering kit, 2.5" spindles and shackles/hangers for 4" drop in rear.  Ordered new brake lines to bend around the new spindles and new brake pads.  The caliper and rotors have some rust on them as well, so I may pick those up when all my other parts get here.  Or hit them with a wire wheel and spray with high temp black spray paint.

Seems they have already been upgraded to the 1.25" rotors as well.

FYI - The top front steering gearbox mounting bolt is missing (upper right corner of image).  Replace the missing bolt and check the others.

Thanks for the heads up, will check them out tomorrow and get the missing bolts replaced.

Good eye on the missing bolt, I have seen some people get a 1/2" longer bolt and put a locknut on the end for more security.

FYI torque for bolts is around 60 to 80 ft-lbs depending on which manual you read.

Perhaps RPO Codes in our Technical Pages will help.

Steering gearbox mounting bolt torque is 75 ft-lbs (1987 Factory Service Manual).

Thanks I got one more code from that sheet still haven't been able to locate the rest.  I was missing the on bolt on the gear box and another one on a  bracket that goes to the front bumper.

After I get my lowering kit installed, I am probably going to order the jegs longtube headers and have a new exhaust welded on it.


Wanting to gave these 3.08 gears swapped out for something like a 3.73 for some more low end go.

Time to get a little Low, 2.5/4 lowering kit.  Have new brake lines and pads, I was going to order upper and lower control arms but Rock auto does not list lower control arms only uppers.  Would like to find a set rather than pressing out the ball joints and bushings.....but looks like I may be rebuilding the ones in it, the lowers atleast can't find them anywhere.


Will also go ahead and replace inner/outer tie rod ends and sleeves, pitman and idler arm while I am in there I guess.

 Climbed back under the truck before I headed to work and all the rubber boots are in pretty bad shape after all and have dirt under them it looks like.
