Should just pull off,if it is plastic
Got rubber gaskets, all that's holding it

As you've already realised, this is serious. The engine is more than likely totally shot. Maybe a broken valve and punched a hole in a piston. Broken piston rod maybe. It's been overheated and also probably blown the head gasket and warped a head. You're looking at a complete engine re-build already. I think I'd just buy a rebuilt long block and start fresh.

if it will not turn over then perhaps its the battery is finished ,old age and its died

1991 GMC K1500 | Answered on Dec 08, 2010


If it only turns over a couple of seconds then your batter might not have enough charge. Try charging it and if it soon goes back to not turning over much then you may need to replace it. You can go to an auto store and ask them to test it. Your plugs will not have an effect on how fast your engine turns over when you are starting it. If they have carbon build-up on them it might prevent it from starting at all. if it looks like compression is leaking through the wall of your plug they should be replaced anyway

gearbox out to repair ,no quick fixya solutions sorry

Any polyurethane caulk should work, shoe goo might work, the clear siliconized acrylic latex might do it, silicone won't do it. Depends on the window, is it broken? Just making a winter bubble? front glass? Wind? Hope this helps.

Sounds like you have a bad connection at the light housing. If you have a volt meter check the voltage at the bulb connector when the brakes are applied. You may have a bad wire coming in at the housing. If you do, the connector can be changed.

adjust the rear brakes up manually ,and grind the lip down on the edge of the brake drum so you can adjust brakes right up before you refit the drum

There are lots of solutions ... here is a simple, easy one ... remove the dome light.

Check also your headlight switch dimmer ... it is perhaps turned all the way clock-wise so the light comes on? If so, turn it back off that detent.
