Subaru_dude Posted March 1, 2007 Share Posted March 1, 2007 '89 gl ea82i think i have a knock. i just changed the oil pump cuz i was bored and my oil pressure seemed to be low. so... i'm bleeding the coolant and as the car warms up... a faint "knock knock knock" and as it gets warmer, it gets louder. at first I thought I left a belt tensioner loose so I took the covers off and checked. nope, they were fine. I find a 2x4 laying in the yard and press it against the driver side head and put my ear against it... "KNOCK KNOCK KNOCK". to make sure it was coming from the block itself, i put the piece of wood on several other parts of the engine and didn't hear it nearly as loud as through the block. the car suffered from TOD before the oil pump swap, but upon startup showed no signs whatsoever of ticking and had plenty of oil pressure. checked around the oil pump pretty gradually after letting it sit there and run for about 15 mins. no leaks. checked everything over a couple times, everything's good and tight. I hopped in the car and closed the door... and it was there, but I just never noticed it before. i guess it came kinda gradually. is my soob gonna die? if i have spun a bearing, is there any way I could fix this without pulling the motor? and if there is wouldn't it just be easier to go ahead and pull it? should I just go ej22 and forget about it?

Skip Posted March 1, 2007 Share Posted March 1, 2007 1) Did you use any RTV or other silicone sealant? 2) How did you hold the "mickey mouse" gasket in place? 1) - if so some could have plugged up a passage 2) - it may have slipped and the pump is now sucking air Quote Link to comment Share on other sites More sharing options...

DaveT Posted March 3, 2007 Share Posted March 3, 2007 and i read somewhere that it may be possible to just pull the oil pan to do rod bearings? To get at the rod bearings remove the heads. Remove the pistons. You cant get at the nuts from the oil pan. Quote Link to comment Share on other sites More sharing options...
