I have a 91 EB with about 183K miles.
I have just replaced both heads with new ones as both of them cracked around 135K and 150K.
Yes, it did run that long with cracked heads.
Apparently, I had alot of sludge because (on the advice of some smart guys on this forum) I recently used SeaFoam and saw my oil pressure at Idle go from about 8 to about 20.
Along the way, my engine has developed a noticeable "clacking noise" and I am worried that it is a rod knock.
The noise seems to start pretty consistently around 3000 RPM, but it will generally start at lower RPM under heavier load, higher under lower load.
It seems to happen much less when the engine is cold.
I dont think it is lifter noise because I recently changed out all my lifters and I heard no difference.
Is there a good way to tell if this is a rod knock?
Does anyone have a rebuild short block they would like to sell?
Or a short block core in socal that they would like me to haul away?
