That's good news,
it should give you trouble freemiles for the rest of its life now. Did you do anything special to the lifters by the way?

Yes...I inserted them into a vice (with the jaws protected) and very gently pushed the plunger in to expel the old oil (with the fill hole facing down). Repeated this several times to remove all of the old black oil.

Then did the Matchless trick of putting them into a pot of oil and pumping them until the air stops coming out of the hole.

You could then repeat this a few times but, I didn't need to.

They quitenened down pretty quickly and are now mega quiet.

All fitted.....6 hours work (had a few additinal bits to sort as I went).

One major hitch.....one of the heads bolts didn't have a washer....so Laidback kindly went to Vardys .....but they had none in stock (which I cant beleave!) so it was a trip to Derby.

Staretd first time and was a bit ticky to start (lifters fillign with oil)......quitened down after about 5 mins and its runs VERY well.......it realy is super smooth.

Last remaining job is to sort one of the manifold studs out (will do it during the week)

Right....two heads stripped, cleaned, new stem seals, valves cleaned and lapped in, faces checked for flatness, exhaust manifolds checked and flattened (one was warped) then fully re-assembled ready to fit.....



So tomorrow is assembly morning.......then 15 minutes of followers tapping like buggery!

One head almost finished (bit of final checking and ancillaries to attach). Shown here following re-fit of the valves, springs, new stem seals and Colet's and under going the good old paraffin leak test.

Thanks for the kind offer MrMcB but I am now getting a lift of Matchless.

Head gasket and bolt set has just arrived, very good delivery service and looks to be a good set.

Will post some pics of the assembled head tonight.

Ok, one head stripped and cleaned, valves cleaned and checked, valves lapped in.

Now need my headgasket set to turn up (82 quid with bolts delivered) so I can fit the new stem seals and re-assemble ready for fitting.

If it doesn't arrive today then head number two will be stripped and cleaned as per above.....

On closer inspection it looks like one of the other inlet valves has also been leaking slightly.

The spare heads are being stripped and new stems seals will be fitted following a good clean and valve re-grind.

Then its assemble and fit, should be running late Saturday afternoon.

In the mean time its bus and train for me to work which, is actulay nice because its different but, it does cost more!

Not had much time to work on the lump today as we have been out to the local kite festival.....

Did manage to get the heads off though..............and this is a shot of the little bugger....



You should just be able to see a section of valve guide on the valve stem, the other piece has been through the engine and knocked a few dents into the head face and the piston crown.

The ones on the piston crown are not to bad and there appears to be no bore damage so I will polish them out.

Lol....head gaskets are not to bad a job on the V6

The plus point is the exhaust manifold gaskets needed changing anyway!

The V6 estate started running rough last week.......DIS pack faulty (on 4 cylinders).

Fitted new dis pack and its now running on 5 cylinders

Anyway, did a compression test to find it low on number 3 cylinder so off with the inlet and cam covers.

Now the heads are VERY clean, as if they have been re-built at some point possibly following cam belt failure?

Well, which ever idiot cleaned and re-built them has done a shit job........they clearly didn't replace the valve stems as one has cracked and the inlet valve is stuck open. Its must have been 'professionally' done as the heads have been chemically cleaned.

What a Muppet, so its heads off time an fit a spare pair.

Moral.....never, despite what any body else tells you, replace only the valves following cam belt failure.....it wont work and is dam right stupid.....

« on: 24 September 2006, 10:38:27 »

Today realy was the big one....with the main Alpine passes including Stelvio.

The passes are realy stuning but......a mechanical problem!

The handbrake shoe retaining pin fell out of the backplate and was rattling around in the drum assembly.

So, after an hour in the car park of a posh hotle and with the aid of a hacksaw, hamemr and a big dollop of fibre glass a bodge was implimented and is still working!

I looks like the car might be returning to blightly, the guys bringing it back are planning to give it a hiding around the Nurburgring!

Only the very late blocks (1996 on 4.0 and 4.6 thor based blocks with crank driven oil pumps) had crossbolted mains, which helped, but was not as good as studs.
