Benn's on going build

Decking the block isnt worth it unless your doing it to increase the CR. If the head looks alright, Don't worry with skimming it.

A hone may get those marks out, I was just being a picky ******* on msn, I'd want it perfect lol

I've been told to fit a gen Vauxhall one.. As i'm not going crazy on power or anything..(first time i've had it apart this much so)

Yep that is the reason for this, couldn't really see any other way it would be leaking and burning it off, I'm getting a bit of oil from the turbo side so i wanna get that check over while it's all off.
I wanna get the engine done right this time, i'm thinking a hone. But as it's only that one bore i'm not sure if it's worth it..

I'm being picky over everything this time tbf.

All my bores were fine Benn apart from one looking similar to yours in the pics.... My builders are very picky and I was advised to have it bored and honed because of this. Deck the block slightly and have the head skimmed. Stick a cometic gasket between the two and things should be spot on. As I needed pistons anyhow though the machine work wont cost me that much more. A set of forged pistons to match bore work however would obviously cost you a fair bit more. Depends how far you want to go I suppose! As sbs would say..... "How deep are your pockets!"! lol

Nick.

See i'm not sure what to do. So... Some people say its ok some dont.. But take it some where to be checked.. But then it was fine before..

if you take it anywhere to be checked they will blatantly say it needs doing just to get some business out of you

Id take it to someone whom you trust for a good opinion. It would be a real pain if in eighteen months you have to go through it all again. (Mind you I bet you'd enjoy it! lol) Do the best you can within your budget Id say.

Nick.

My engine is a similar spec to what you will be running Benn but I fitted a cometic gasket and arp's throughout just for piece of mind that it would be stronger. Just wish I'd done the clutch and oil pump right first time......

That's the prob Luke,

Nick as above i don't have any where i trust.

I've been thinking about fitting ARP for piece of mind.

Is a Cometic really needed?

I bought my cometic due to piece of mind and not being a great deal of money off Steve
