Smile Good News, Broken Chain Ramp

One might ask; How is that good news? Because its not something else .

Am I safe with the little bits of plastic that might be lingering or should I try to flush the case with somthing?

Shortly after installing my SSI's and M&K 2/2 I started hearing a strange noise ticking and assumed it was the a exhaust either leaking, valve ticking or just a new exhaust sound. Then last week I was out driving around in a "spirited fashion" and it got a bit more noticeable under load. I got under and retourqed all the exhaust nuts etc, definitely no leaks.

So checked all the valves, (they were all dead on) and double checked everything, checked the head-studs, no issues, buttoned it back up and still got the same noise. So I drained the oil again and this time a few small chunks of black plastic came out, took off the chain covers and found out I was short a chain ramp, luckily most of it was still in the chain housing and the rest came out of the sump plate.



This is the first time I have had the tensioner covers off, probably the first time anyone has seen the inside of these in 30 years, original tensioners and no safety collars. I am considering upgrading to new tensioners, but might just go with collars, these things have been in there 30 years whats another thirty?

I am assumming the ramp was just old and brittle, I will replace them all. It was the lower right inboard ramp.

Am I safe with the little bits of plastic that might be lingering or should I try to flush the case with somthing?
