Hooked up a 5 gallon removable saddle tank to my on board air so I can run air tools if I ever want to.

Finally got around to installing the new parking brake cables that I have had laying around for a month or so. I even used my new air system.

Pulled the siezed 258 out and opened it up. Good news theres not and metal peices or bent rod any where to be found only found the engine bearings to be damaged, not sure if that the correct terminology for it (metal sleves that go in between the connectiong rod and crank. ) found them to be practiclly welded to crank on #5 and #6. My only guess was oil starvation. Any ony else have any clue what might have cause it?

Connecting rod bearings...probably an oil problem. If you intend to rebuild it then you need to send it off to have the block flushed and you need a new oil pump and pickup tube. BTW, I've seen FAR worse.

thanks for the info. Is that what can cause a motor to seize?

Im going to take it for a complete rebuild. Called around and its between two shops. they are about $200 diff btwn the two. One is $1900 and the other $2100. Both 30 years+ in the buisness.


I thought it was something catostrophic that it was going to be a cmplt loss on the block

There are some different variables and alot of times the just plain wear out. Whichever machine shop you use, take your crank to them also. They may be able to polish it, it may have to be reground or you may need to track down a new one.

Take the crank to the machine shop first. It may be cheaper to find a used engine ir just trade your engine as a core on a rebuilt long block.

After a week of pulling my hair out with the brakes, new calipers, new rotors, pads, lines, rear cylinders, small parts kit, proportioning valve and 2L of fluids pumped through i was ready to call it quits and bring in an expert. I couldnt get a hard pedal or effective brakes whatever i did. I did suspect the booster was stuffed BUT i should have brakes regardless and it should have been hard to press if the booster/master was stuffed.

Started to remove the booster and found the pin holding shaft that goes into the booster wasnt connected and was pushing the booster rod a little then sliding under it. God knows how the PO drove this thing like that. The booster shaft was actually worn on the underside so it had been like that for a while.

I now have BRAKES!

Booster is stuffed as with the engine running when i press the brake the engine stalls indicating a vac leak inside the booster but thats an easy fix.
