Orangetang Posted May 25, 2010 Share Posted May 25, 2010 The poor Pathfinder got a little too deep, once again and subsequently bogged out in some muddy water. I winched it out and gave it a turn with the starter and it did about a half rotation before stopping. Pulled the coil packs, plugs, and cleaned the wet ones up, turned the engine over and put the plugs back in. It fired up and ran fine after a couple of tries. I checked the oil and there seemed to be no water in it, and the level hadn't chaged. After an hour or so heading it developed a slight knock around 3500 rpm at which point i checked the oil again. No oil. ?! No leaks, no blue smoke and no oil in the coolant. The filler cap had some sludge in it so I figured it gummed up and wasn't being pumped, or somehow burnt up or evaporated? A friend towed me to the highway and I called AMA... Before bed I drained the oil or what was left of it, refilled and started it up. Still knocking, and not idling properly... Will stall on its own in Park. I changed the oil again and went for a drive. The engine is knocking at a lower RPM now, basically 2000 and up, and has little power but feels balanced and sounds nearly perfect. No shakes or vibrations. I might be optimistic in wondering, but could a wet/dirty coilpack or plug cause a knock? My guess is bent piston arm or valve, or worse, even though any case is pretty much a write off with these things. Any help is much appreciated. The last engine I did this to has a two bent piston arms, and thats about as far as I looked at it, though it drank a lot of water, this one not so much.

GrimGreg Posted May 25, 2010 Share Posted May 25, 2010 Wet wiring at the MAF or other sensors, wet coils or wires can cause poor running. Link to comment Share on other sites More sharing options...

87BeachCruiser Posted May 25, 2010 Share Posted May 25, 2010 Pray that GrimGreg is correct. Yeah, you went from best case scenario to worst case Ontario in two posts there. Good luck. Link to comment Share on other sites More sharing options...
Orangetang Posted May 27, 2010 Author Share Posted May 27, 2010 I think I probably flattened a rod bearing when I tried to crank it over. That was probably my big mistake, since it pretty much stalled out without locking at first, or as far as I know. That probably covers the knock, that or also running out of oil... The unsteady operation is more than likely wet electric something. It sometimes idles fine for several minutes and then just turns off. Sadly I'm not even going to try and diagnose. Gov't of Canada is giving $3000 to recycle a vehicle such as this when buying a new F-150, and since that is above what I could get on trade-in, or sale. With that and the huge discount my company gets, I'm going to try and buy one. I already miss the Pathfinder and it hasn't happened yet. Link to comment Share on other sites More sharing options...

Tungsten Posted May 29, 2010 Share Posted May 29, 2010 I would take the R50 over an F150 any day. Link to comment Share on other sites More sharing options...
Orangetang Posted May 29, 2010 Author Share Posted May 29, 2010 (edited) So I've got an 09 Honda Fit and 02' Pathfinder representing Japan in the driveway and an all-American, Microsoft infused F-150 taking up the rest of it. I can't believe how big this truck is for a 1/2 ton... ARB, winch, lights, stereo, scanguage, tires/rims, etc, all coming out of the Pathfinder before they pick it up next week. I drove it around for an hour or so today, probably for the last time Stay tuned for a parts thread if you really want the bumper or whatever. I'll be reasonable. Shipping is probably brutal though. PARTS THREAD YEAH! Edited May 30, 2010 by Orangetang Link to comment Share on other sites More sharing options...
Orangetang Posted June 8, 2010 Author Share Posted June 8, 2010 I guess we are out of the 'pick-up' region, so I drove it out to the Dimsdale, AB auto wrecker on Saturday. No more Pathfinder Link to comment Share on other sites More sharing options...
adamzan Posted June 8, 2010 Share Posted June 8, 2010 You sent it to the wreckers with that arb on it? Link to comment Share on other sites More sharing options...
Orangetang Posted June 10, 2010 Author Share Posted June 10, 2010 No I sent it to the wrecker stripped of everything I put into it. There is a parts thread above if you're interested. ARB is sold. Link to comment Share on other sites More sharing options...
