This afternoon, my Justy started making a gawd awful noise.... It sounds like I'm driving a jackhammer! Did I throw a bearing? Or do I have a stuck valve? What could the problem be?

Give more info. RPM related? does it do it on idle, acceleration, what? Using the phrase "like a jackhammer" doesn't sound minimal. Me thinks you might have a problem. Expound fair sir!

 

 

First Day of Vacation,

It appears to be more pronounced at around 2000rpm. Above there, the engine seems to settle, and once it builds oil pressure, it seems to be ok at idle. It's very pronounced, though, upon first starting the engine.

My thought would be connecting rod...I'm also a pessimist...dammit.

Time to invest in a mechanic (read: needle) stethiscope. Any parts store worth walking into should have some on hand for around $10. Youll be able to diagnose a connecting rod from a push rod (are justys pushrod even?) from a valve etc etc etc

 

"until it builds oil pressure" -- scary...

The only thing I have seen make a suby beyond help is rust.

Well, I talked with a friend of mine... He listened to it, and suspects that one of the bearings has slipped, meaning replacing that, turning the crankshaft, resizing the connecting rod, and resizing the piston. Or, replacing the engine. Far too much work, and too costly. So, it's off to the junk yard for the ol' girl. Sucks, cuz I really like that car, but it needs so much other work.

 

As long as the engine was ok, I didn't mind putting the other work into it. But, now that the engine is shot, the car isn't worth fixing. It'd cost me $2,000 to fix now, and it's just not worth it.

I feel for ya. My 86 "Blubaru" game to a grinding halt last month.:boohoo: Not worth fixing.
