It's probably the front seal, which you don't need to remove the pump to fix. The actual oil pump removal involves dismantling the engine.

RedPath88 Posted July 24, 2007 Share Posted July 24, 2007 GP is right, it's likely just your front seal. Which means your going to be doing the same thing you jsut did, all over again Link to comment Share on other sites More sharing options...

PATHY90 Posted July 31, 2007 Author Share Posted July 31, 2007 it looked like in between when i had her running.right at the joint. and she was leaking bad..usually about a quart a day driving about 40mile. i know it wasn't from the cam seals. i even cleaned it up to check again. and i was definatly from the joint.

Wipe/hose down the entire area as clean as you can get it, dust it with talcum powder or cornstarch, then run the engine again and watch it to see where it's leaking. Most likely, it will be coming from the front main seal. It is, however, possible that you cracked the oil pump housing while doing the timing belt if you pried off the crankshaft sprocket as is preferred. If that's the case, you get to remove the engine to fix it. Link to comment Share on other sites More sharing options...
PATHY90 Posted July 31, 2007 Author Share Posted July 31, 2007 so the end restult is i have no choice but to remove the engine to remoce the oil pump??? dam that sux Link to comment Share on other sites More sharing options...
GhostPath Posted July 31, 2007 Share Posted July 31, 2007 so the end restult is i have no choice but to remove the engine to remoce the oil pump??? dam that sux Only if the oil pump housing is at fault. It's far more likely that it is the crankshaft (not camshaft) seal at fault. Link to comment Share on other sites More sharing options...
PATHY90 Posted July 31, 2007 Author Share Posted July 31, 2007 if the crankshaft seal was a fault wouldn't it be leakig from the front of the engine? instead of were it's leaking now? Link to comment Share on other sites More sharing options...
GhostPath Posted July 31, 2007 Share Posted July 31, 2007 In theory, yes - in practice, the fan can blow oil back beyond where it's leaking. Link to comment Share on other sites More sharing options...
PATHY90 Posted August 1, 2007 Author Share Posted August 1, 2007 understandable but i have no oil near the crank...so i'm ASSUMING it's the pump...BTW y dose the engine have to be taken out to remove the pump? i don't think it's cracked just needs to be reseal.

Sounds like you cracked the housing getting the crankshaft gear off. If memory serves, you must remove the engine to drop the oil pan and crankshaft to get access to the backside of the oil pump housing. You have to detach the pickup for the pump. I've attached a pic of the system below. Edited August 1, 2007 by GhostPath Link to comment Share on other sites More sharing options...
PATHY90 Posted August 3, 2007 Author Share Posted August 3, 2007 DAM. that just sux... now i have to think of a way do go around this...don't have the space and tool to remove the engine... Link to comment Share on other sites More sharing options...
5523Pathfinder Posted August 3, 2007 Share Posted August 3, 2007 (edited) You do not have to remove the motor from the vehicle, just going to take time to drop the front diff. Here are some directon for you..... Disconnect battery ground cable. Remove air duct from engine compartment. Remove cooling fan. Disconnect upper and lower radiator hoses. Remove fan shroud. Remove drive belts. Remove crankshaft pulley and front and lower belt covers. Remove undercover, then drain engine oil. On 4x4 models, proceed as follows: Disconnect front propeller shaft from differential carrier. Remove front driveshaft attaching bolts. Remove front differential carrier member bolts. Support front differential carrier with suitable jack and remove attaching fixing bolts. Remove front differential carrier bleeder hose. On 4x4 models, proceed as follows: Remove differential front mounting bolts. Remove front differential carrier. Remove front differential carrier mounting bracket. On all models, remove idler arm. Remove starter motor. On 4x4 models, proceed as follows: Remove transmission to rear engine mounting bracket attaching nuts. Remove engine mounting bolts or nuts. Remove engine gussets. On 4x4 models, raise engine if necessary and disconnect exhaust tube. On all models, remove oil pan attaching bolts and the oil pan. Loosen bolts in sequence, Fig. 1. Remove oil pump assembly. Reverse procedure to install, noting the following: Apply a continuous bead of suitable sealant .138 - .177 inch wide to oil pan mating surface. Tighten bolts in reverse order of removal. I have done several oil pans without pushing the engine up or even loosening the mounts, but others I have. Make sure you take your time, borrow a torque wrench for the pump so you dont overdo it! I would make sure you are 100% that its the oil pump. I would make that decision after I tore the timing belt back off and make sure you didnt nic a seal or something like that.
