Timing chain early warning

lookskyward1 · Dec 11, 2013

As some of you will recall, I had an issue with my sump being rusted.

After draining the oil I removed the sump to find these pieces of plastic chain guides in and around the oil pickup.

As you can imagine this really freaked me out as I was not aware of any 'chain slap' noise so I've got myself a wee project to do. I have bought a new FAI single chain direct replacement from Ebay although Eurocarparts are doing it cheaper now.

I am at the point of needing to remove the crankshaft pulley. and trying to make up a tool to lock the pulley so I can undo the bolt.

My Navara is a 2007 Euro4 model with manual transmission. it has 106k miles. I suggest that if anyone has anywhere near this mileage that they remove the sump to check for debris.

Why aren't you duplexing it?

Bad news Keith but good you've found it in time.

Think I'll drop my sump when I change the oil next. Just to check. Thanks for the heads up.

Cost basically. The kit cost me £268 delivered. but it was going to be £850ish for the conversion kit.

The present setup has lasted the 106k, 26k of that in the last three and a half years by me. I doubt if I am going to do another 100k while I own it, it would take me 26 years at this rate :lol:

I can understand that, pointless if your flogging it.
I'll keep mine til it rots to death, hmmm ... Perhaps I don't need to do my chain either :lol:

I also fitted that FAI kit, quality seems second to none, and so far so good. my chain wasn't near as bad as your's though, the plastic guides had wear grooves but they weren't broken, you'll also find one of the guides in the new kit is modified and longer at the point where the original wore away the most. I went for the more expensive kit with replacement cog gears.

About the crank pulley, I managed to get it loose by jamming a nail bar/crow bar thingy into it, and put it in such a way that the chassis leg resisted it from turning, I then got a huge 5 foot tube and put it on the end of my ratchet, and pulled it as hard as I could,. You'll be amazed at how much force is needed to crack the bugger.

Don't you just love these motors !
Good news on the find

That's me starting the rebuild now, it has been a bit tricky up till now but hopefully everything I've done will be OK.

The old lower chain was really sloppy, the tensioner piston was almost popping out of the cylinder :nailbiting

Here's the lower tensioner chain guide, it has worn right down. fortunately there is no damage to the casings.

OMG... I am surprised you have not had the chain snap already!!
Talk about dodging a bullet mate! Phew!!

You caught that just in the nick of time, I'll post up pics of mine if I can find them, Mine's looked like new compared to that.

Is there a way of getting a endoscope in to see if there ok ?
Or is it a sump off and have a look ?

I doubt it could be seen without a stripdown, even with an endoscope.

There is an alloy main sump and the much smaller steel sump pan underneath that which is about 250mm behind where the chain is.

That's a bit of a pain ,think I'll pull the sump to see if I have any bits in there
I alway thought I would here the chain but after seeing your pics iam not so sure
