Cadbury's Chocolate Camshafts

[warpspeed]

Preliminary investigation of my suspected timing chain tensioner failure is now pointing to the cams. On close inspection with lug holes last night all the rattly racket seems to be coming from the cam covers. I therefore suspect that the lumpy bits on the cams are a littless lumpy than they should be and consequently the buckets/followers are forked too. Has anyone else suffered this fault and if so what was done and how much was the remedy ? Time to call Richard Thorpe methinks.

Discovered worn cams and buckets on mine during the big service.

Yup, mine did that at about 50k miles.

The 4.2 that went in the racer went like hell, but upon inspection x months later by Dulfords was found to have knackered cams.

Cams 400 x 2

Labour and VAT brought it up to around 2K.

Since moving the lamda sensors to get a better reading devoid of extra air through the Ex gaps on a racer 350 was had on the rollers...which will do for now (4.5 in shed with good cams ready to go)

Similar numbers here.

same story here, similar pricing, 55k odd miles 4.2

a lot of the clatter went away once done though

Seems to me that's a very respectable mileage for a cam. Even on the RV8 it's quite common for them to go at half that mileage.
