Ok so I pulled the oil pan and, just for shiggles, also did a compression test. Rod bearigs looked pretty worn, It was shiny and silver in the middle and the outsides were a brass color. Didn't get any pictures because I wasn't thinking about it at the time.(Doh!)
Main bearings were a dull silver color with scratches:
Yes I could feel the scratches on the bearings with my fingernail
A couple of the mains didn't have any size markings like .001 like some did, this one here is an example:
Could it be assumed that these are STD? the rod bearings were either marked .001 or STD. but none of the mains had an STD mark.
Here are some pics of the crank
I also checked the cam, no wearmarks from what I could see, looked real clean.
Also the timing chain had about a 1/4 inch of play in it but there's no sound coming from the front of the engine so I doubt that's the issue.
All the main clearances were around .0015 to .002 nothing over or under that. All rod bearing clearances were between .0015-.0025.
The sound is coming from both the rear of the engine and the middle. Didn't get a chance to check the rear-most main bearing, doing that tomorrow morning.
Also one more question:
I used plastigauge to measure the clearences ond one of them came out fat on one end and skinny on the other. Does this mean there's something wonky with the crank or did I just position the sting weird:
Fixed the pictures sorry about that
