Hi Brake Buster,
You have posted a great deal of information about replacing the tensioners. I'm unable to view the pictures that you posted and was hoping that you wouldn't mind emailing them to me. My address is Stephens_Ant@yahoo.com. Any and all help is greatly appreciated from all.
Thanks

Nice to see the dealer sharks trying to cash in as usual, I made my own camlocking tools , cost around £10 for the 2 , thats materials, labour ... obviously not the dreaded VAT.
Dealer price $120 plus! come on! ....... how do you leeches sleep at night? Any small machine shop with even basic equipment would make 2 in 15 mins

Let me pass along something that my mom used to say to me. "If you don't have anything nice to say, don't say it at all."

There is a very good write-up of primary tensioners and loads of photos here

Why could'nt you remove the cam bearing tops so as to lift the cams up from the back and tilt them forward....remove the old tensioners and install the new ones.
If you did that and did not remove the chain from the sprokets, then no need to lock them down.......just replace the bearing caps and re-torque ....?

Batroute and Green01XKR, I went both ways. I replaced the secondary tensioners with the zip tye method first. Once the chain is tyed to the sprocket, you have secured the timing as it was. Whether it is the proper timing is another matter. If you had tensioner failure, as I did, you could be off due to the chain jumping a tooth. The chain may also be damaged since it contacted the metal shoe of the tensioner. I decided to go the full route including chains. Once you have the timing cover off, you never want to go back there again, so replace the chains; it's really not that much more. The primary tensioners didn't look too bad, but the alignment blades were worn and cracked. I only had 66K miles, so maybe another 30K before another failure. In the end, having everything apart gives you the opportunity to get to factory alignment with new parts. The peace of mind is a bargain at twice the price.

Guess thats what i have to do then, since driver side chain is deff in contact with tensioner metal shoe... How does one remedy chain jumping a tooth(assuming no damage to valves) ??

If the secondary chain has jumped a tooth, the engine will run rough. With the timing cover off, you can turn the engine slowly by the crankshaft bolt and watch the rotation of the camshafts. There are two flat places at the ends of the camshafts nearest the chain sprockets. If there has been no jumping of a tooth, then somewhere in the rotation of the engine the two camshaft flats should lie in the same plane. That is, a flat bar would sit across both of them. If you can't see that condition, then the timing has slipped.

Guys , I am in dire need of the tools to do a complete timing chain and tensioner replacement, I really do not want to pay $250.00 to $499.00 for them, If some one can rent them, Loan them, to me or sell them to me at a reasonable rate, please let me know. I have parts coming via ups, and want to start this job this week. Thank you in advance.

I'm about to change my secondary tensioners(no noises yet - I just want to sleep at night) and thought I had seen something somewhere about removing a spacing plate underneath the gen.1 units when replacing with the later spec. - I've searched the forum but can't find anything - can anyone advise whether this is correct or not - apologies if this has been covered before?
