I'm fitting a new cam kit to my head which has just been skimmed. relapping the valves etc and fitting all new gaskets. I've been told to run the cam at 2k rpm for 20 mins to bed it in. After that what do i do?I've heard loads of different things, get it checked, run it for 500 miles off boost retorque head then have it setup. what do you guys think is best??

 

ok , if your putting in a new cam and recond your head.....there is no mention of new lifters, unless you get them in your kit, you MUST use new lifters for a new cam.

when you put the cam in i would sugest useing graphogen to assemble the cam and lfters. librally coat both cam and lifters, graphogen will then disapate into the oil as it warms.

ok so before you start the car take the plugs out of the head if you have allready fitted them and remove the hall sensor plug on the side ofthe distributor....this will stop the fuel.....crank the car over for a few mins or so to give the oil time to get to the top of the engine.

so now put it all back together and start the engine, hold at 2k for 20 mins and then you are ready to go....

you must use some boost NOT NO BOOST, for the first 100 miles or so but go easy with the revs 4k max for 200 miles or so...then your cam should be nicely beded in.....

asumeing you havent rebuilt the block and its just the head, 200 miles is fine for a sensible run-in....bed-in time for a new cam...

good luck...

 

cheers, much appreciated.no retorquing of head?and the sensor is that the only one at the side of the distributor. thanks

 

the sensor is the one on the side of the distrib... when you take this off it stops the fuel pumping in the engine, and stops sparking,

cvh uses strech bolts so there is no need to re-torque, make sure you do the correct levels of tighten.....

refer to the haynes manual, but i think its, all to 36nm, then 57 nm, then 90 degree turn and after 30 mins another 90 degree turn,,i think...

best look at the book tho
