2.9 V6 Engine Rebuild
Discussion
Hi all,
As Richard continues with the chassis, my attention is on the engine. Today I've removed the heads - pictures below. Looks a bit manky...but this is the first time I've ever removed a cylinder head so don't have a lot to compare it to!!
Looking for recommendations of what to do now and how far to go now. I wanted to renew all the seals and gaskets, including the head gasket and inlet manifold gasket which had a small leak. I was intending on just cleaning and painting, but now I have it so much apart, is it worth deconstructing any further or parts to specialists to be refurbished? I'm thinking the heads themselves, pistons, bores etc? There were no major issues when I started the rebuild apart from the oil leak.
I'm in the north west - if anyone has experience of using companies for this kind of rebuild it or advice as to what you did and didn't do that would be great!
Cheers,
Andrew

Should probably have just emailed you again Mike 
De-coking...best method? Read on internet and oven cleaner seems to be a common choice but seems to be a lot of cautions about the alloy on the heads? Is it more advisable to just soak in a degreaser overnight and some elbow grease with a pad? I also have some carb cleaner in the cupboard as an option?

Heads aren't alloy but pistons are! I wouldn't want any dodgey chemicals going down the side of the pistons.
Scraper (old wood work chisel) and rotary wire brushes are your friends.
Valves should be kept in order and put back in same hole they came out of, do you know how to grind valves in?

Just a good old fashioned "de-coke" pop the valves out and lap then back in imho.
Wise words indeed. Just a good old fashioned "de-coke" pop the valves out and lap then back in imho.
The only thing I'd add, and it's not been mentioned so far because it's stating the bloody obvious/teaching Grandmas' to suck eggs, but anyway, remember to re-new the valve stem oil seals.And maybe check the valve spring lengths are all the same. Keep these in the same order as well.
Heads have been refurbished by Redmond Engine Centre in Fleetwood - great guys to deal with and have done a cracking job. Decided all this lapping the valves back in etc. was best left to the professionals, so they've done all that and given them a good overhaul.
Got them back on saturday, so been in the garage all day today...wait for it... REASSEMBLING,
Man it feels good to finally put something back together... Very pleased, and I think my new rocker covers set the whole thing off very nicely....!
All in all...progress. Rich making good progress with chassis, trailing arms etc. etc. so should hopefully be reassembling even more very soon!

Hi Andrew
Great job - When do you hope to have the finished car back on the road?
I also bought some rocker covers from JR Casting (I assume that's where yours came from too) a couple of months back and an likewise chuffed to nuts with them.
Where did you get the 'shiny' air ducting from please and did you look for the original black option and if so did you find a source for that?
Cheers Martin

Hi Martin,
Thanks! Hoping to be back on the road in 12-18 months if all goes to plan!
WRT the air ducting - I've got from car builder solutions, however, don't get it! It's much flimsier than I was expecting (it was only cheap) and Richard from Southways (doing my chassis!) has advised it will last 5 minutes once on the road.
As much more robust alternative, Richard has suggested these guys - and using a combination of silicone hose and alloy pipe. I decided not to try and get what i need until I have it back on the car so I can see the angle etc. that I will need to make it up.
Richard has used for his 2.8 - picture here: clicky

This is the twin-walled wire reinforced silicon ducting hose I fitted to my S1 to replace the rather shabby original. Excellent robust hose, it's been on for well over 3 years now.
It was supplied by ASH, same as Richard ( Kitchski )'s recommendation
I chose the blue with orange inner wall, they also supply it in black.
