My 92 has developed a little bit of a knock, at idle and hot. The oil pressure is low, about 3psi hot at idle, above 1000 rpms the oil pressure is good, and the knock goes away. I did a compression test and had 125-130psi on all cylinders. I also have alot of smoke on startup and am going to rebuild the head. I do have to replace the oil pan gasket, so I will have access to the rod and main bearing. I am debating just throwing new rod and maybe main bearing in it while its open. Obviously if the rod or crank journals are trashed then there is no point in this. My thought is I drive the thing a few hundred miles per month, I really just want to stop the cloud of smoke on startup and stop the oil leaks that are ruining my garage floor. I am hoping that when I open up the pan the pickup is cloged up and that is my oil pressure problem, but thats doubtful. I am thinking that replacing the rod, and maybe main bearings would up the oil pressure if they are worn. Oh, btw, 175k, and not sure the previous owner new they were supposed to change the oil....Any thoughts on just doing bearings? The head is a given, the valve seals I believe are shot.
