    What is this part I found under the dash?

    It's funny that I was working on wipers and this mystery part is something for the wipers. I looked it up and it is a delay module. So new question, where do these plugs that come out of it plug in? They were unplugged when I removed it so they have never been plugged in since I've owned the truck.

    1985 K5 350 always running rich?

    The PCV is new but the grommet around it is not in the best of shape, I wouldn't think just the grommet would cause this though right? yes, my bad. I must've confused the two in my head when writing the post. It does burn he eyes a little, the fumes are inside the cab and just as bad when...

    1985 K5 keeps breaking starters, help!

    Engine starts perfectly smooth. I know it has to be hitting or it wouldn’t break I just can’t pin point when it hits. I have already checked the clearance with a drill bit and it was perfect and had the brace and proper bolts so I know it didn’t move and still broke the starter. I have a flex...

    Thanks for the advice, I currently have it running on two extremely thin shims, waiting for the inevitable failure and will probably upgrade to an ac delco starter to see if it last longer.

    @Bextreme04 it has an external cooler, never had any fluid out of vent tube, have not checked the level while running or the temp of the lines. It’s making a boiling/bubbling/popping noise inside of the pan.
