Guest alistair Posted March 31, 2005 Share Posted March 31, 2005 (edited) My Pathfinder 91 4wd automatic gives a knocking noise once it heats up. Also checked the water pump and the belts noting!! My mechanic is sugesting low oil presuure or oil pump problem. Please help desperate. Could you also give me any self help on how i could fix. The oil light does not come on. The mechanic said the oil flow is not at its full. But he said to try it out for a week as I did a flush on he engine. I do not know if this will effect but I also get high smells of fuel when I start the engine. Also the noise comes only when the car is heated up. Also the description of the car on idle is a long kurrrrrr......and then skip and again a kurrrrr..... Could someone please send me advice on the above. I would love to fix the problem myself if I had some advice. Edited March 31, 2005 by alistair Link to comment Share on other sites More sharing options...
k9sar Posted March 31, 2005 Share Posted March 31, 2005 you need to know where the knocking is coming from. While it's running (and making noise), see if you can tell if it's from the valve covers, oil pan, or elsewhere. Link to comment Share on other sites More sharing options...

Guest alistair Posted April 1, 2005 Share Posted April 1, 2005 Tried all that the only part left is the engine. Link to comment Share on other sites More sharing options...
k9sar Posted April 1, 2005 Share Posted April 1, 2005 there are many parts to the engine. Knocking in some of them is easily fixed. Knocking in others is fatal. Could be a lifter, could be a piston, could be bad main bearings, could be a stick jammed in the fan blades. Don't just assume the engine is shot. Figure out what part of the engine and we can be of much more help. Link to comment Share on other sites More sharing options...
94extreme Posted April 1, 2005 Share Posted April 1, 2005 could be timing or all kinds of other things.. Link to comment Share on other sites More sharing options...

SC88Pathy Posted April 12, 2005 Share Posted April 12, 2005 It's not politicians it's the stupid DMV. Of course you could still do the swap not tell anyone and maybe "grease the wheels" of your local smog shop. sssh Oh and then never get pulled over.

Slick Posted April 14, 2005 Share Posted April 14, 2005 unfortunately my "friendly" smog shop got busted and closed down a couple years ago. This Dec will be my first time smogging the Pathy (I bought her Sept '03 with smog cert)... I do so hate Cali for all the very EXPENSIVE laws they have here..... Oregon is looking better everyday.... then I could have my 350... and do all kinds of wicked cool stuff to her.. darn..... :contract: :furious: @ California Link to comment Share on other sites More sharing options...
SC88Pathy Posted April 15, 2005 Share Posted April 15, 2005 (edited) If you absolutely can't pass smog slick you could drive to Watsonville, I'v heard that the smog shops there are very friendly, especially with Washington, Lincoln, and Jackson. sssh As for my Pathy it's been smogged twice since it's been in my families possesion. And it better pass next time I get it smoged since we spent quite a bit getting the EGR system fixed. :furious: Edited April 15, 2005 by SC88Pathy Link to comment Share on other sites More sharing options...
