upgrade kits

[fricker]

Hey there, I have a 70 911E and been worried about the stock tensioners. Does everyone here agree that doing the pressure tensioner kit is a must?
And I also have a bad leaking exhaust system, I will be keeping this car for a long time and would like to put on the ss exhaust system. Does anyone have any comments about this exhaust.
Thanks
Chris

The opinion is split on the carrera tensioner upgrade. On my 72E I just installed the collars and never had a problem. As to the SSI's they don't get any better.

If your chain ramps have never been changed, I would recommend changing them when you add a collar or go to the Carrera tensioners. The original chain ramps were made of rubber that hardens and becomes brittle with age and oil exposure. What blew my engine was a piece of chail ramp breaking off and falling between the chains and intermediate gears. Cam timing jumped and the engine went clunk!. A sound you do not want to hear. The new ones are plastic and impervious to oil. Check them.

Not Normal. Looks like you opened just in time..

i have had a few early cars, and I would not feel comfortable driving an early engined 911 without the carrera tensioners and the late ramps installed.

When you listen to the debate, you have to take notice of the absence of carrera engined cars with tensioner failures. Chain tensioner technology is a common thread across almost all european OHC makes, and the Porsche solution seems to be the most durable and reliable around...

there was a post about measuring the chain and cam gear slack.

otherwise changing both seems to be the way to go.
