Camshaft Issues

[Knight Rider S4]

Right getting through everything but having a problem with the camshafts when i put the bearings on it is locking the camshaft ...have oiled them when putting in and tightened them up in order of inside out .....when i slacken them slightly it turns but i am not tightening them to tight to start with so puzzled??......

Any help or advice would be appreciated

Did you put the caps back on in the right places?

[Knight Rider S4]

Sure i did 1 starts at the cam wheel going along then following its way round

[Knight Rider S4]

what way should they be facing .....as in the number 1 is front of you looking from EM

Are you sure the caps are facing the right way round?

Need picture to be sure any on here?....cant remember

[4WheelDrifter]

I've got a couple of heads here somewhere, I'll see if I can get a picture.

Here is what we are talking about, you need to check this on the car AFAIK ( the middle paragraph )

Hmm...
Just looked at the RR head i have as a door stop in the conservatory and if looking from the exhaust side of the head, the numbers on the caps are upside down. So from the inlet side they should be right way up if that makes sense!

[Knight Rider S4]

Dohhhhhhhh!! looks like i have put them upside down

Cheers

twoqu's right. Of course. The numbers should read right from the inlet side. It's the end cap on the inlet cam at the pulley end that can be confusing.

also not a good idea to mix them up either as they are unique to each part of the camshaft

[4WheelDrifter]

The caps should stay with the head they were align bored/honed with. Swapping camshafts is no problem. It's the same with the block and main bearing caps.

As they are assymetrical you stand a very good chance of cracking them if you have fitted them the wrong way round.
