I'm going to be changing the upper tesinors on my 99 xj8l. I am needing some info on the zip tie method. I can't seem to find any. Thank u. Also the car has a bit of a stumble when u first push the gas then it smooths right out. At an idel in park if I just push the gas pedel really easy it almost dies. But it I push it on down it revs on up like nothing is wrong.

 

The reason you cannot 'search' on 'zip tie' is that the forum software will not search on less than 4 characters in a word.

Here is the link to the original posting on the zip tie procedure but there are others with pictures that I cannot find at the moment.

Hi
I copied these 3 links for you:
This one shows you the ziptie that has been placed on the timing chain.

Next one is a PDF with instructions and pictures on how to take the cam (valve) covers off to inspect the secondary timing chain tensioners.

The last is a webpage link to the thread on how to do the ziptie method.

Look at the early posts #1 thur #8.

Hope this helps you.

Thanks guys for all the help!!l

 

Hey I'm back Im still loving my jag!! but my grandfather gave me a 00 lincoln ls with a 3.9 v8 i know the motor is really close to the same as my 4.0 in my jag. Any one know it the timing chain tensonies are the same? It really needs them changed but I'm finding limited info on the web. I know this is the jag forum but I know u guys are great on these motors and questions thank u

 

I don't know but would guess yes as you can use the Ford parts on the Jag I assume they evolved at the same time.

 

The Lincoln LS 3.9L is really the same as the Jaguar 4.0L and the Lincoln tensioners and lots of other parts are commonly used on the Jaguars. The Lincoln never came with plastic tensioners and should not need attention there.

 

Well my 00 ls does have plastsiic tensioners I can post pics if you want the passenger side was really bad I took it apart last night just to see and same red plastic ones as my jag but was in far worse shape now I know where my top end rattle was coming from

 

Thanks for the reply and correction! Never heard of a Lincoln LS tensioner issue.

 

Tensioner failure is very common on the LS V8s. For LS info I use

Lincoln LS - Lincoln vs Cadillac

I've owned an LS for 8 years and love it. Someone hit it while parked and that's why I'm looking at this site (possible replacement).

 

After reading the part about your LS I'm going to pop the hoods and compare the engine in my 02 T Bird with my 03 vdp. I assume they are very similar also.

Engines in the t-bird and the VPJ should be very similar.

My LS is a V6. I've been driving 34 years and so far I've only owned cars with manual transmissions and RWD. One of the things I'm still on the fence about on XJ8s is the auto transmission. I do my own work and while I've changed clutches I usually get over 150K out of them so it no big deal. The MT's only need simple fluid changes and are not fussy as to what fluid is used. Going auto will be a big change for me.

In the type of car I'm seeking (4 door rwd) manual transmissions are few and far between (at least in the US), especially used ones.

 

So just a fast question the tensioner on the passenger side of my Lincoln the top was totally broke off that is were all the noise was coming from. The car was running but really ruff with no light on. Is it possible that it could have jumped one tooth on the timing and if so can I just move the cam back to where the flats line up when I get the new tensioners I ordered?

 

It all depends on how much it slipped, 1 tooth ok, 2 teeth bent valves.

My suggestion....do a compression test by using a bar, socket and hand turn the engine over on the crankshaft pulley nut, to test each cylinder, it should pump in the region of 160-180psi for a happy smiley face.

If it checks out ok, it's a case of replace the tensioners and time it, then button back up.

 

I have already done the compression test and all were fine just wanted to make sure it was OK to move that lower cam while I had it lose back to where the flats line up

 

ok so looks like bad news i put the new secondary tensioner in the passanger side and looked good turned motor over by hand and at one point and its where the cam flats are lined up there is enough slack in the chain to put my finger between it and the tensioner but if you turn it just a bit past it is tight agian is this ok or is the chain streached to bad and i need to get a new one and if so anybody had any luck with the chains that have master links?

 

The tensioners (by definition) are supposed to take the slack out of the chain. However, they are designed to only move in one direction - out. That means that they cannot cope with a chain that is stretched in places, which sounds like what you might well have.

 

Oh, I forgot to add: The tensioners have a little pin that keeps them retracted until installed. Then you pull the pin and the tensioner moves out against the chain. Did you pull this pin out?
