please check this damage

[cantfindausername]

I've never had to deal with a damaged engine, as mine was good and healthy when I took it apart.

However, Ninas V6 is a different story. I thought that the top end sounded a bit tappy when we had it on the road, and when we finally got the cams out it looks like its been a bit starved at some point in its life and has led to some wear on the cam journals.

Here are some close up pics of the damaged areas.

Is this sort of damage terminal? What should be our next move with this?

Thanks for any advice,
Ant

Adamski/Tony are the boys on this but dont look good thats for sure!

Hopefully they'll be along to comment/advise sooner rather than later.

Agreed that it doesn't look good.

thats some pretty deep scoring and looks like its picked something up in the oil for sure!

Are they all like that ?

[cantfindausername]

No, not all the journals are like that. Not that I noticed anyway. I will double check later in the week. We've not checked all the bored yet either, hopefully they're all ok.

[cantfindausername]

Yeah I thought that would be the case. I'll get my dirties on again this week and have a proper look at the head and shells to see how they are.

I'm hoping Johnny or someone else has some cams laying around from swapping out.

Hopefully the head and shells will be salvageable.

id agree with the head journals bieng allright for some careful precision polishing provided the bores arent undersize from damage, i can check them for you ant , coming JAE?.. i'll bring some measuring equip. use a diamond lap compound in general, can do for you if you like or supply a small amount , its expensive lol. as tone says the cams arent really re-grindable without putting some meat on them first.. the total limit is infact 0.016mm from top to bottom of it.. you would take that on setting up / touching off with 'one cut' on cylindrical grinder, if not even it would be pretty damn close to half a thou, that would take you on the bottom limit straight off. better off finding better cams, i'll measure it all up if you like.

Adam, unfortunately we're not gonna be able to make it to JAE, however, if we could run them down to you at some point that would be just as good for us!

I've not found any cams from the links that were posted up in my wanted ad :(

Not 100% sure what way we can go about this at the mo.
