I've changed rings and not had the block re-honed with no problems. Although this is my experience and may be not the done thing

The problem I got (of many!) is its only the one ring and the middle one at that, I'm not wanting an easy way out but does the whole block need to be re-honed for one middle ring thats being replaced on the one piston and thats it?

I know its silly not doing the full monty while I'm here now but doing any of this wasn't part of the plan!

I starting to love that phrase "If aint broke don't fix it?"

I've changed just 1 ring with no problems, but as I said, just because I didn't have any problems doesnt mean others havn't.

its pretty easy to rehone a block, personally if it were me i would run a hone down the bores seeing as its that far apart. but youll get away with just replacing the one ring and not rehoning.

[alexcrosse]

With Vauxhalls you find its almost impossible to get one piston worth rings, let alone one ring; you can easily get an entire set though. If you have got everything apart like that I would replace all of the rings.

And if you have everything apart I would also get it honed, though the surfaces look very good it will only take an a moment in a machinists and cost you around £25.

It will give you a clear happy mind knowing that the most important seal in the entire engine is fresh and brand new And neither take much, so you may as well use this opportunity

Or you can even pick up a hone tool that fits in the cuck of a cordless drill from machine mart for around £20 (ish)

Well whether I like it or not I know the crank has gotta come out and get the block honed with new springs fitted all round, great



Started off with taking the main caps off - 13mm





Haynes manual is a bit backwards on how to actually remove a crankshaft, I think its all in there but I cba to go through it properly as I wasn't in the mood

On the flywheel side you need to take off the 10mm nuts and prise off the seal to get the casing off, would be alot easier to do without the engine stand brackets in the way so took my frustration out on the seal





I feel better now



On the other side you gotta take off the casing held with 10mm and a couple of 12's which I think might be the oil pump? (I honestly don't know!) but my bracket which holds the cranks sensor was in the way so thats gotta come off aswell



The crank cog (I honestly don't know whats it called!) just pulls off



Couple of gentle taps and its off





Now you see it



Now you don't





Oh joy



Only two washers came out? Is that normal?



As I will be getting the block honed I wasn't sure if these oil ports needed to come out?





But took them out anyway, bit fiddly to pull out



Put the main caps back on keeping everything as it came off, all the bearings are in there original places

I would also get it honed, though the surfaces look very good it will only take an a moment in a machinists and cost you around £25

Called up an engine builder round here and he said to hone one cylinder completely he would do it for £25 if I'm only gonna change the spring set on that one piston that is, but if all the walls are good in the block with criss cross upward strokes



which they are, he'll skim them all for £50

I don't think I need to remove anything else off now for them to do it so will pop it round to them - when I can be bothered

I effin hate cars, wish I stayed on a bus!

So whens the 2 litre turbo going in?


Still dont see how any of this is relevant to a clutch change, but if youve got money to burn, you may aswell

I aint mate, this was all unplanned, the engine has to come out to change the clutch and while it was sitting on the floor I thought I might aswell 'just' change the head gasket, things went a bit weird after that

[Burnard]

You mean far.

You will never be welcome in the exclusive club that is "that'll do engineering"
You need your own "while were here engineering"

[samsfern]

is that the b16 engine cam?

[Kam]

is that the b16 engine cam?

cam or kam? are you asking me if thats a b16 engine or if thats a b16 engine and cam?

Yes its a standard B16a2 engine I've got but I've now bought a set of type r cams for it which are used in the B16b engine

[GreaseMonkey]

Dude, what happened?!

Good stuff though, credit for having the kahunas. I remember my first engine strip down "just to make sure everything was okay" turned into a massive rebuild

[GreaseMonkey]

Also the two washer things are normal, they're the thrust washers. The poor buggers that stop the crank going tits up when you put your foot on the clutch

[alexcrosse]

he should do all of them for £25 imo, 50 is a normalish price for a skim too.

Good work though try to enjoy it =p lol

Cheers for that mate, that really helps

Yeah I'm happy and enjoying it Also he probably thinks I drive a honda so I'll go armed with some pics and mention its for a mini, might get a few quid off

[alexcrosse]

Lol, go to a mini place, if they no what their doing they are usually happy to do it for realistic prices, spured on with the excitement of working on something other than bloody A series =p
