Well as i have been working with carbon fiber recently, i was wondering if anything has to be done to the carbon fiber to help it with the heat or the engine, so the resin doesnt melt? or would it be ok to just use?

I might make a mould of one of my rocker covers and have a go at making one and just see what happens if i run it on the engine.

Search please for more detail.
This came up a little while ago. Someone was planning to start producing cheap carbon rocker covers but when various more experienced carbon fibre fabricators started listing the problems that will crop up they all decided it would be impossible to produce one cheaply and it would cost about £100.00 retail. Curiously enough when Play Mini were making carbon rocker boxes they were selling for around £100.00, surely not just a coincidence? In short the resin will melt yes but there are many other problems too.

if you go for a high temperature resin system it will cope with the heat ok, as long as you post cure to the temperature it will see on the car.

but as mentioned before, carbon discolours at anything resembling underbonnet temperatures, and will tend to go a brown colour.

you need to make an aluminium fitting for the oil cap, as the carbon won't hold up to a direct fit one.

And its not worth the financial outlay!
