Recommended Posts

I was going to upgrade my cams when i saw this..

 

the car had a new oil pump installed when i got it dont know the reason for this ?,, oil pressure is about 6-8 bar at idle when cold and about 3 when warm,

 

i always let i warm up before i rew it and so on,, i have driven it about 4000 km since i got it 3 years ago,

 

the caps look worn to me but dont know how they are supposed to look ? and there are some metal pushed out to the edge,,

 

can this bee repaired or do i need a new head:( ? any input appreciated.

 

cheers kris

They look fine, most engines of this sort of age will have a bit of scoring from dirty oil and general old age and poverty, I wouldn't worry about them at all. If you have access to accurate measurement tools you could attempt some checking, but camshaft bearings are very hard to measure properly without sophisticated gear. I'd just leave well alone :)

thanks for the help:) i will remove the head and scrape all metal off from outside the bearings and just give it a god clean,, i have new steam seals/ springs/ retainers and cams going in anyways

 

will make installation much easier with the head off..

 

thanks again
