Hey guys - I am after some know how and advice! So far the forum has offered up some good info but I feel I have now exhausted the search button.
My navara hadn't been running that well since I first brought it. I have researched the forum over the last month since buying it and have tried the easy fixes, as most suggest, to fix her lack of power. I solved it! well partially - air in the fuel line and pukt turbo hoses. Cool I was stoked.
But this is where the fun started. Shes also been making a pretty scary, non rhythmic, rattle type "clack". A serious one I decided... after reading the word "grenade" on the patrol forum! So I took her into the Nissan dealership - thought id get a professional opinion on what it could be. Probably should have asked you fellas first!
A mechanic had a listen and said they had to open her up - off with the timing chain cover. I didn't see the harm in this as it sounded like, and I thought it could be, the timing chain. They said the chain looked ok, although a little slack (aye? its either satisfactory or it isn't, which is it? haha). They said they could replace it but no guarantees it would solve the rattle clack.
Before I had it to the dealers I took it to the bloke who skimmed the head on my jet boat and asked whether it was something in the head. He had a listen and suggested it sounded like something free floating in the head (heart sunk) due to its non rhythmic nature.
So I told the dealership mechanic who said ohk we will take the rocker cover off and have a look. Nothing obvious showed. They suggested they run a compression test as they couldn't 100% identify where the trouble was. They said it ran 420,420,400,380 psi from cylinders 1 - 4. I looked it up and the manual says this is within the 43psi range tolerance (although just). Anyway - they said we have to keep digging further or another option, as pulling it apart was going to cost a ton, why not put a second hand engine in!
So after saying it would cost me 3-4k for a timing chain replacement or 10k for a second hand engine - and a bill for 4 hundy bucks - I had a laugh and towed it home. A mate has lent me his truck for 3 months while hes overseas. So the navs at home till I can save up to fix it. Or i could have a go myself.
I had a poke around after I towed it home and I found metal filings in the oil filter (they hadn't removed it). Wish I had done this before taking it to them. Not a good look.
So that's where I and my Nav are at. Can you help me piece the bits together haha. What could be causing this non-rhythmic clacking sound? How would you go about fixing it?
Cheers - JT
