Cam Chains and Gears

Looking for advice on replacment interval on Cam Chain/Drive/Gears being worried my 1993LSC with 127,000 may need that kind of work - also seems the engineering design is near bullit-proof enough that it may not be in my lifetime but wanted feed back on this kind of work

Also, someone in the past offered up a tubular engine sub-frame - did that thing come to life - I remember photographs - is it real?

RE: Cam Chains and Gears

The timing chains and such are not maintenance items. They are not easily replaced and not many people have to tools or experience in working on an over head 4 cam engine. If something breaks you probably better off replacing it with a crate engine. I think one guy on here has over 250k miles on his engine.

Yes. I have one in my car. What function do you believe this holds for you?
 
RE: Cam Chains and Gears

It appeared to allow greater servicability and access. Mine is fairly messy and I need to replace some gaskets that have shrunk which have decided to weep oil - car spends too much time in the garage I guess. I was thinking that dropping the engine out and doing a total cleanup - the tubular sub-frame would then have a play in that action... so functionally - better access and serviceability. Reality as you may point out would be that a stock version that has been allowed to get messy may deserve funding in other areas more that the sub-frame.

Was the sub-frame a 1-off, patented? Is the cost... high?

Thanks for your consideration and quick responses.

I believe AJE makes the tubular k-members for our cars now. Not sure how much a new one cost?
 
RE: Cam Chains and Gears

For a new Tubular setup you are looking at around $1000 in mild steel. $1200 in chrome moly. What I sold my complete frame for was a steal.
