I have stick, spring compressor and paste if you need it.  

 

That kit at £99 is good - so buy it

Yep, FAI if the pic is to be believed so ought to be reasonable.

What do you mean by lap the valves Kevin - grind them in?

Yes, exactly. A little grinding paste and a stick with a sucker on the end.

Excuse my ignorance in this area, I've never removed a valve!!

Go for it! Follow Mark's procedure and you won't find anything difficult in rebuilding a head after the jobs you've tackled in the past. It's one of the more satisfying car jobs, in my opinion, too.

I'm not sure that valve spring compressor would have enough reach to go down into the bores where the hydraulic tappets live. I have one that would that you're welcome to borrow though. I (hope I) won't need it for some time!

Side to side movement is not good. It's probably best to assess this after you've removed the valve springs and colletts. Drop the valve back into the guide without the spring and see if it has significant movement side to side.

I wouldn't normally worry about changing the valve springs however the engine has done a good few miles so maybe they should be checked. Depends also on the cost of replacement versus your plans for the car vis a vis selling it on or running it yourself for another 100K! Stem seals will come in a head set anyway. I'd probably change all the exhaust valves if I were you. Inlets will probably be OK as they run much cooler but change them if the stems have worn.

Jobs like changing the valve guides can be done by a local engine workshop. Little jobs like that are very reasonable if you bring the bits in to them ready to go and they don't have to do all the time consuming disassembly, cleaning, reassembly, etc. They should also be able to advise on the condition of all the components and measure them accurately where required. I came across a very helpful local workshop when I last trod this path. He also supplied replacement bits at very good prices.

I'd lap all the valves back in on reassembly, obviously. After that mileage they'll need it.

What does the bottom end look like? Bores OK? Compression looked good on the Ok cylinders so I guess it's probably in fine fettle still.

Have fun!

It is AMAZING what a dishwasher does to a set of faded pre-facelift headlight lenses

Have you tried a dishwasher on a cylinder head? They bring them up a treat! Go on, put her to the real test  .

You'll need to let it fill up and then open the door and chuck a bit of Jizer in on top  

I remember when I built the Westfield there were bits of car in EVERY room in the house. Couldn't store much in the garage because I needed the room to work on the car.

Oh, yeah. But then I was single then. Happy days.

Ahh. It's the Forum's birthday so it's TB's birthday... Happy birthday TB.  

Still, that doesn't explain his absence. Wurzels it is then.

Maybe I should go and get some green neons, some awful wheel trims, a silver gearnob and a pretend exhaust pipe for the Veccy...

Or a pipe and some slippers?  

I came out of watching "the fast and the furious" to see two Smart Passions Neon'ed up outside the McDonalds opposite the cinema. Sad, really. If there's ever a case of money that could be better spent elsewhere.... They could have had the engine from my strimmer for a start.

As I used to live in South africa I must say I am surprised to hear that.

Well, it was pointed out by a local tour guide so maybe a bit of poetic licence there?

There were certainly quite a few sliproads from the outside lane that just stopped after 100 yds or so.

The M8 in glasgow does indeed have a right turn from the fast lane, no it isn't onto another motorway.

Interesting. Cape Town has these all over the motorways that run through the city. Many of them are simply blanked off and don't go anywhere. Rumour has it the construction company who designed the network of flyovers, raised motorway sections, etc. was drafted in from the US and they failed to notice that South Africans drive on the Left (correct!) side of the road until after they'd poured the concrete so most of the exits are from the wrong side of the motorway!

Think yourself lucky it's not a Mazda   £208 from main stealer  

Did think about going to a scrappy for that but it's one part that, previous mileage aside, isn't going to appreciate sitting in a field getting damp.

I doubt plugs will gain you anything. My theory is that they're either giving a good enough spark to light the mixture, and the engine runs, or they're not, and it misfires

Platinum plugs and the like are really just to extend service intervals as they last longer.

The standard Vauxhall plugs are good quality 2 electrode (or 4 in later ones) and not too dear.

Induction kits aren't reckoned to do much other than increase noise and there's a real risk of increasing the intake air temperature if you ditch the airbox. A a K&N panel in the airbox might be worth a try but go easy on the filter oil because if oil mist gets into the MAF sensor it'll get the hump. Induction isn't the main restriction in these engines. The exhaust manifold design is pretty pants and this is probably the first thing to address. Not too many options to change that unfortunately.

Cheers,

Kevin
