I stopped by Tom Charlesworth's shop today to discuss a chain and pad inspection. He quoted very good rates. Similiar to what I posted at .net last year.



We talked about the job and what was involved if the cams were missing teeth. He has had good luck with repairing the cam sprockets and has them done locally.



If anyone is interested in the service give him a call.

FWIW, I just got off the phone with Tom - more out of curiosity than necessity. But boy, could I have used that 8 month ago when I bought new cams.



The fact is that there is major concern with warping and gear strength of a repaired/welded cam and gear vs. a new unit. I didn't ask the cost, but Tom reports that he has rebuilt about 20 sets of cams with no failures or issues reported on the rebuilds.



No need to have the car sent to Oklahoma...just send the cams.



Not passing any judgement since I haven't used his services. But it looks like a viable option.



Best driving wishes,

Exact, like bolt for bolt? I think you are a good enough wrench to pull the valve cover.



Once off, the thing you are looking for are missing teeth on the cams. Bump the motor over on the starter, or turn the crank and and look at all the teeth.



Also look at the tops of the teeth and look for knife edging. A normal cam gear will have a land at the OD of the tooth. One that is wearing thin will come to a sharp point at the tip.



Also, look at the tensioner pad between the links of the chain. If there are deep grooves, say more than .020" (the thickness of a credit card), then it might be a good idea to start planning a tensioner and chain job. Small grooves or scuffs are OK.

Its possible to take the valve cover off, and just replace the pads without taking the chain off??

this in case of the chain and cams look fine?!

Money is a bit short lately...?!!

Changing the two pads requires removing the cams. Once you've done that, I'll bet the chain looks simple.

Vedder, I am in the process of doing this very job. Are you planning to do this job yourself? If so, I would be glad to share the pictures I have taken as the job has unfolded with you. Just let me know. <img src="/forum/images/smilies/968/smile.gif" class="smilie" alt="" />

Excellent! I have been waiting for an opportunity to contribute to the DIY section. From this point on, I will proceed with the job with the idea of creating a comprehensive write-up of this job. I am still unsure as to just how deeply into the engine I must go. So far, I have removed the valve cover, performed both cylinder compression and leak down tests. At a bare minimum, I will be replacing both camshafts, the upper and lower tensioner pads, and the camshaft timing chain. There is also a possibility that I will pull the head and have it freshened. I am weighing my options right now. I could go ahead and post pictures of the work I have done so far, if anyone is interested. <img src="/forum/images/smilies/968/smile.gif" class="smilie" alt="" />

Does anyone know the part number for the pads? what that about a beefed up timing chain??, and /or have a explode diagram of the timing chain area?

Here you go:



Upper Tensioner Pad--944.105.509.00



Lower Tensioner Pad--928.105.509.01



Camshaft Timing Chain--944.105.501.05

NPS thanks for chasing down those elusive numbers.



I ordered two chain pads from Sunset a while ago - now I wonder if I got two of the same. <img src="/forum/images/smilies/968/huh.gif" class="smilie" alt="" /> What exactly is the difference between the upper and lower?

Apex, if you installed two upper pads, that should be just fine. <img src="/forum/images/smilies/968/smile.gif" class="smilie" alt="" /> Actually, I am back to a state of confusion concerning the pad issue. See post #7 in this thread:
