guys, I started this morning on the left bank, at the point when I need to lift the lower cam shaft, everything is removed. god damn thing would not budge, i see it separating from the bearing on the right side but other than that even when i try to pull with all my strength, nothing. should i keep applying force up on the right hand side where it is already started to separate.

Little taps with a rubber mallet while having a second person there to lift it out will help. My right bank was much easier than my left bank. Hope all has worked out.

+1 on tensioners replacement

thank you everyone for your help and guidance. everything is covered well on this forum. I would only add that probably a good idea to start with the right side since it is easier. And also make sure you are working on all five bearing caps on cam shaft. I originally did not notice the one closest to the sprocket and broke a cold sweat fearing I could break the shaft since the other four were already removed at that time. Fortunately I got lucky. My right side tensioner was in really bad shape, ready to fall apart. Left side had a crack but not so bad. Interestingly enough, it appears that somehow there is more oil in the right hand side of the engine as compared to the left one. I mean both sides were covered in oil, but on the right side it was dripping of all the parts.

regards

If anyone is interested I do have CAD drawing file I done of a full tensioner tool set, I was going to make my own but ended up buying them instead

I would love to get a copy of those drawings if you don't mind. I have been searching the internet for hours looking for them. I am a student on a tight budget, but I have access to the schools machine shop.

Attached are a dimensioned set of the drawings from XKRacer. Let me know if you find any issues. I am currently making a set and will update them if I run into any issues.

Thats a proper job and certainly worth keeping, I will add though on pages 7 and 9 that is suppose to be a 5/8 or 16mm thread of whatever description you would like, that is the bolt and puller for the crack pulley.

Hello Everybody.
Getting ready to do the secondary tensioners. Are there any gaskets between the tensioner and the cylinder head?
Thanks,
Bill

XRacer, HellHound,
Since I'm oldschool on dimensions...inches/.001" I presume that all of these dimensions are metric. Correct?
Thanks,
Bill

No, there are no gaskets, but you do need to get the correct (shorter)replacement bolts.

Add me to the list. Started out trying to find lost oil and found 2nd gen tensioners. Plastic missing on right bank, and both banks were splitting.

Couple of quick notes on the job were that I was able to do the drivers side without messing with roatating the dip stick tube, just removed the dipstick itself. Also I was able to re-use the 40mm bolts by grinding them down to 35mm. The bolts have just enough thread so that they can be re-used.

Thanks to all who helped.

If you car was running bad due to a jumped tooth on one cam sprocket, you have to retime that cam. I'm guesing that you can eyeball the flat on the cam close enough to get the right tooth-link syncronization. you will have to get the crank shaft to 45 degrees first. (you can stick something in the hole where the tool goes.)

If you had a tooth jump the chain should be replaced also. To replace the chain you need to remove the timing cover. While your in there (and it is a big job to get in there), you might as well do the primaries and guides too. I would not consider doing that job without the proper tools.

Doing anything less in your situation is false economy IMHO.

Default Basic valve timing

The whole valve timing is really simple. When you put the crank locking tool in according to instuctions, you lock #1 piston at top dead center (TDC). In order for the engine to run right each cam has to be right to make the exhaust valve just closing and the intake just opening. (There are small minor adjustments which the designers have made to increse performance, etc) Each cam has a flat spot that must be flat or parallel to the head surface when the #1 is at tdc. The other bank cams have to be on their flats also. There are other factors to consider to get this perfect so follow the book get the tension perfect, etc.
My secondary chain jumped a cog so I'm forced to do the above timing. I also want to replace both 2nd chains and do not want to take off the front cover so I am considering the chains with a master link. Have any of you guys used these with success?

Default Master Link

Check with this company as they are the experts.

Emerson Power Transmission
(www.emerson-ept.com/eptroot/public/prod/dynamic_frame.asp?strMain=http%3A//www.emerson-ept.com/eptroot/public/prod/msechain/msechain.htm )
)

A master link could help a lot!!! I think it might save a lot of hassle instead of tearing everything apart.

Also look at these:
http://www.transeals.com.au/catalogu...e-Imperial.pdf
and
Results for Roller chain & sprockets:Metric roller chain
( www.fremontindustrialsupply.com/servlet/the-Roller-chain-%26-sprockets-cln-Metric-roller-chain/Categories )


Hope this helps.
