woke up this morning got in the vx, only to notice when i started it a slight knocking that gets louder whe i give it some gas. wtf??? oil was a little lower than normal, got the oil changed with 10w40 today with a new filter. knocking isnt as loud but i can still hear it. im having a bad day.
is it too late to ask for a new 3.5 for christmas?:_crying:
Is it actual mechanical knocking, or could it possibly be the "dieseling" knocking that happens when that nut at the bottom of the egr tube comes loose?
im not sure. its almost non existant at idle and i can only hear it now if i pop the hood and rev the engine.Quote:

will do man.
my mechanic also said sont worry about it unless it gets worse
check that nut under the egr valve,mine didnt git put back in when i had my intake gaskets replace and made noise that sounded like my engine was tapping,i was so relieved when my noise was gone after i put it back in.:)
will do. ill keep you posted
Depending on current mileage, maybe your mechanic(s) are just thinking it may be close to valve adjustment time. It's difficult to differentiate between the two (valve noise and loose egr nut) without actually hearing it though.
well he didnt say anything bout that. but i have about 52000 milesQuote:

:_brickwalwell the knocking got wayyyy worse.
going to the dealer tomorrow. hope its covered under warrenty.
That sucks. When my Xterra's engine started knocking, it wasn't very long before it went kaboom.
Keep us posted.

i think im gonna hang out with my buddy jack daniels tonight.:cryy:
From the showroom floor, my VX always had "some" knock to it. On some vehicles, knock is a "feature", like on Subarus. Boxer engines come with a luxurious slight knock that you get used to. I always assumed this was pretty much the case with our 3.5.
Since putting my S/C in though, the knock has increased slightly as well as the added S/C ticking. The knocking got much quieter when I switched to synthetic, but by the next oil change, it was back. I did some heavy inspecting when I had the engine torn down when I did the S/C install, but nothing stood out. I guess its just one of those things....
Good luck and keep us posted.
yes in my research i found that a small knock is ok. however it sounds like something "inside" the block wants to get "outside". im going down the dealer in a few to talk to the mechanic. ill keep you all postedQuote:

any thoughts???
the warrenty does not say anything about when a motor isnt covered.
In all honesty, if you have the time, money, and care to keep the vehicle, its worth it. Otherwise, its really probably just a hassle. It all comes down to, how much does the VX mean to you. :confused:
Sounds like the dealer just doesn't want to mess with it. I've never heard of an engine that was still running that couldn't be rebuilt cheaper than a replacement ('course I'm not a mechanic so I could be talkin out-my-arse).
my friend works at this particular dealership. if he says its not worth fixing then i believe him.Quote:

"if he says its not worth fixing then i believe him"
Not to be anal retentive but I'd love to know what he's basing that on.
I was told once that I had a blown engine (throwing oil everywhere - too much head pressure). It ended up that all it needed was a PCV & oil breather ($8 & 5 min labor). That was back in the good old days though when shade tree mechanics could actually fix their rigs. Engines are more complicated now so he may be justified - maybe I just think too much.:)
i understand where youre comming from. its not a little issue. when i say "something inside sounds ike it wants to get outside", you can here big chunks of metal moving around inside.
but they are going to tear apart the motor to see exactly what went wrong,per the warrenty company. so ill keep you guys posted. and ill try to take some pictures
oh, and thank you guys for all your help... seriously thanks!!!
well got a call for the dealership today. they tore the 3.5 down and it spun a bearing. the warrenty company is going to come down and take a look at it. i hope they dont try to screw me .
took some pics

check out the bearing in the middle of the first pic.
the warrenty company wants to tear it down even further. i think they are just dragging out the inevitable
The way it sheared, it looks like a defective bearing (but I'm no expert).

had to get the lawers in this. he is calling the insurrance commisioner today.
why cant people just be honest insted of triing to screw the little guy all the time...
i just want my truck back.
the warrenty company wanted to have the top part of the engine torn apart. for some reason they wouldnt tell me that, soooo i quess any progress is good progress.
now that i have the motor out of the vx, what should be replaced on the 3.5 now? (besides the parts that are broken.):_confused
front suspension system and axle, transmission, engine, transfer case, driveshafts, tires... :p
Always, always, always replace the torque converter seal when you have an engine out. Sometimes just the mucking about can ruin them and it's just so easy while the engine is out.Quote:

If you get the crank ground at all make EXTRA sure they nitride it & stuff or you'll be sorry. I'd try really hard to find a "new old stock" crank - I think I've seen them listed on a few auto parts sites.
The 3.5 requires new head bolts, since they're torque-to-yield. I've seen kits on Ebay for much cheaper than the dealer charges, so be sure to get those sooner than later. It also calls for new torque converter bolts, but you can get those from the Help! section at Autozone, etc..
A lot of people like to replace valve seals & stuff when they have the heads out of a car. Personally I don't mess with them unless it has been blowing smoke. If you do go after them, just pay a shop to recondition the heads - they'll come back in near-brand-new condition and be sure to seal properly the first time.
I bought one of those gasket sets from Ebay when I first tore into my engine right after I bought it. The intake gaskets that come with that kit are crap, but the head gaskets seem to have held up OK. If I had to do it over, I'd order an OEM kit or something like Felpro.
Good luck!
thanks. printed....(not yours zeus!!!!)
anything else?
Think about a Tranny dip-stick - easier to add while it's out of the VX.

Oil pump, egr tube, and water pump are things I have heard mentioned before as well. Check Dino's posts for working on the fuel pressure regulator too - should be easier with the motor out.
got a call from the mechanic today. the inspector for the warrenty company is out there looking at it.. i really hope they dont try to screw me!
