There doesn't look like there is much metal missing BUT, it's still somewhere in the motor. Metal chips and shavings circulating in the motor is...

As painful as it sounds, it is hard to argue against Graham's logic above since I suspect a past bodge is at work here and you may struggle to...

Motul oil is as good as it gets, so that is not the issue. I think you just need to pull the head and get it checked out a set, head, springs and...

Graham and Randall, Thanks for the responses. Graham, I think you were typing the same time I was! There's some further info in my post. ...

Compressed air into the sparkplug hole will hold the valves closed while changing springs or seals--if you have good valve seats. What kind of oil...

Mike, You're right, the big question is what caused it. These cams are welded and reground and there were signs of wear on a few other lobes, both...

Only one cam lobe, the rest are perfect. I some ways the damage looks like flaking, but in some ways impact damage. Do you know if it was a billet...

You always have great write-ups Mike of your various track experiences. Nice photos and video, great driving on track!

As a person who knows all about camshafts melting down on dynos recently :ack: :banghead:, you have to ask why it happened before you repair/replace....

The sky in the video is incredible. . . . 3204 :jester:

I know I’m kinda taking a bit of a hiatus right now, (busy with...stuff) but that would 3203, Mr. Croc. BTW, love the Brands Hatch thread. :hurray:

Kitcat. Darned spell checker.

good luck and let us know how your rebuild goes. just found this. https://www.sevener.fr/fichiers_articles/Manual_Type9.pdf

For those who this may help, the Ohio builder of the S1 (Snakebite) put our a service bulletin that mentioned that some of the fuel wiring...

I have done 4, T9 overhauls now but they were all 5 speeds I don't know how similar they are to the Cat 6 speed though. Here you go:...

When i pulled the yoke from my 6 speed, i had to move the rear diff back a few inches in addition to moving the engine forward a few inches while...

Good info in the links. Thanks for posting. -Mark

I'm about to go through my Type 9 this next weekend. It will be my maiden outing. I'm going to install a BGH close ratio gearset along with new...

Sean, Thanks! I'm really curious about the restrictor in the de-gas line. I wonder what it's purpose is? If I use the drawings you sent as a...

The following diagrams may be of use to you: Duratec cooling system, with heater: PDF, for saving: JPG, for immediate viewing: Duratec...

Sorry about the upside-down sketch! The orig. was OK, but it flipped?!?!?

AHHH! Just described how the system is plumbed and was timed out! Attempt #2... Mike, Thanks for the drawing, it seems the builder of this car...

At least for the 2.0 curated there are two water outlet connectors: one plastic, one cast aluminum (same part number :) When I finally managed to...

If the diagram is correct? I would not think that having the temp sensor in the heater feed line would be ideal. I would verify the location of your...

This is from a very useful build blog that I have referenced in the past. Its for a Caterham 360 - so a 2L Duratec but the principles are the same...

I was out and about today. A Bit brisk but still an enjoyable drive !
