Just got off the phone with a local place who says he will have a look at them for me and advise whether they can be skimmed. If they can he'll charge £25 per head to do them.

Is it ok to just have the one skimmed as long as he takes no more than 10 thou off?

I don't like using places that i don't know and I'm wondering whether its worth just getting a new head from someone on here that I trust? :-/

I would take the head to a local engineering firm to get their opinion before condemning it, tbh. It's difficult to assess it without seeing it in the flesh and we might be worrying about nothing. If it can be skimmed it should be a relatively cheap fix.

Assuming the other head is OK I see no reason not to change just the one. I believe there were differences in the oil pump design which necessitated changes to the lifters and the oil supply valve in the head, so I would either try to get a head from a similar model year or swap these parts from the old head.

See if the old head can be resurrected first though.

I thought I had read that the V6 heads shouldn't be skimmed? :-?

Looks like I'll have to invest in a new head then.

Can I just get one or do I need the pair? I assume it needs to come with all the valves, followers etc to match?

like the neatness labling all the bags 

That is a big chunk of metal missing there  - Maybe a replacement head as well as HG?

That was my fear! Is it worth even bothering to clean it up or has it had it? :-/

Took some pictures of the heads now they are all stripped

1,2,3 Bank





[size=12]4,5,6 Bank - Little concerned about the deep gouge on the outside of number 6 cylinder which is where the HG appeared to have perished![/size]







And here are a couple of pics of how I kept all the followers, valves, springs collets etc in the right order!

Omega General Help / Re: Oil Cooler - where is the best and cheapest?

« on: 01 February 2010, 18:28:28 »

Vx is reasonable on TC I think. Failing that you can get them on Ebay for around £90 -£100 IIRC. Not sure about the quality off ebay though as not had experience of them

"Do it properly" and "Half heartedly" indeed! What sort of insult was that meant to be?
Some interesting comments made but it would be nicer if they had stuck to the 'how is it done part' instead of commenting on the advice of others which should left in the General Discussion area. At least I had pointed to the Maintenance Guide as an assitance.
My comment was supposed to help, not invite put down comments from those who took longer for whatever reason. As with every other job it depends on the skill of the person, the seriousness of the problem and the availability of the correct replacement parts should any be needed. Cleaning time cannot be estimated either.
Couple of hours yes - if you have not got everthing to hand ready as I had because I had pre-planned the job!
It took me just under an hour to do the job 'properly', including the throttle because I timed it from my start time after I had collected everything I needed and had it all to hand. It was also not in such a badly maintained state that it required any longer.
Now retired, I have been in the motor fitter game for over 30 years, nearer to 40 and so I have many years of skills and practice to count on. I dare say there are some even quicker than I was too.
Just follow the guide I pointed you to M8 and if it takes you hours or days at least you will know you have done it yourself and have the satisfaction of knowing that! Its a very good guide so you should have no worries if you follow it and don't try to shortcut it.
I was not to proud to take advice from Darth LooKnee either.
GudLuk

It wasn't meant to be an insult at all.

As LD said I was just saying how long it took me to do the job for the first time (obviously the more you do it the quicker you get).

I followed the guide too and would recommend that anyone else does the same. And I have taken advice from Darth Loo-Knee on more occassions than I care to remember.

Agree with Geoff.

To do it properly takes at least a couple of hours. No point in doing it half heartedly

Flush the system out severall times. Use a good detergent of some sort. Some on here recommend the product that Forte make especially for the job. When I did mine I found neat Traffic Film Remover from Machine Mart does the job (after advice from someone else on here) and is much cheaper!

Is there any way the Oil cooler is reusable by cleaning it (sorry not mechanically minded)?

If not where can I buy a cheap one as I am in the process of selling the vehicle but have only stumbled on this problem yesterday.

Chris

No, its metal and its degraded so much its now letting oil out of the cooler. Best option is to get the oil cooler kit from a Vx dealer on TC its around £90+ vat

If your handy ish with tools tis not a bad job, otherwise its a 3/4 hour ish job at a garage

45 minutes? :-/

3 to 4 hours spanner time sounds do-able....

Flushing out the old oil from the cooling system will take more time and it makes sense to flush out the heater matrix while the system is empty.

I think Tunnie actually meant 3 to 4 hours

If Tunnie can do it in 45 minutes then he could make a fortune just doing oil coolers!!

When it comes to re-filling the antifreeze can I use the Halfords Advance antifreeze or do I have to use genuine Vauxhall antifreeze?

And how many litres is required?

Note: it does say on the halfords site that there advanced antifreeze meets manufacturers requirements.

Is it any cheaper than Vx stuff if bought on TC? From memory Vx is £10.89 for 5 litres (which is all you need) on trade club.

There must be someone near you with a TC card. Alternatively PM andyc on here and he will sort it for you (although postage might be a bit steep for 5 litres of antifreeze)??

Omega General Help / Follower servicing

In his Head Gasket Change guide James mentions a guide on servicing the followers written by Mark.

I cannot find it in the maintenance section. Anyone help me out?

Just had a reply from andyc and apparently the copper stud has been replaced by the stud and copper nut
