Sunny day today…..

I had a peek under the cover today and the car is still there……

So went into the garage and continued the work overhauling the engine. The old cam was well worn so will be replaced with a better example of what a bump on a cam should look like….

This will then make these

push the valve caps onto the valve seals, so machine the valve guides to move the valve seal down by 2.1mm.

48 hours to the Irish Classic Retro

Yesterday I spent the whole day working at the car. A few minor mechanical tweaks, a lot of Dinitrol anti-rust spraying and fitting body work including a the little trim bits.

After putting all the badges on the car I found another badge in the bottom of a box. During the respray some of the badge holes in the boot lid have disappeared. I can’t remember where they all go!

Hitting the pins into the trim clips on the wings and doors was causing heart in the mouth moments, thinking I’d dent the panels, until we broke the pins out in a visce before inserting them with plenty of Dinitrol anti-rust pasted around the hole.

Once completed the car is starting to look good. Just the valences left to fit.

O, the wheels are in the delivery van on the way here now!!

Back to the body

A quick post with a few picture showing where we are now.

After collecting the doors and wings from the painter I built the doors.

And at Tims the bare car was still being welded. We had intended to spend the day painting and hanging panels but we just kept finding more and more rust as we were preparing to paint. Both front sils were replaced, the two jacking points strengthened and finally both the driver and passenger side floors had repair patches welded in.

As Tim welded I painted the D posts,

and after short break.

We hung the doors and rear wings.

So now we wait again for the painter to catch up, by finishing the remaining panels.

Still no new wheels.

Tightening the LSD

With the Jag IRS out of the car, I could strip the 4HU LSD and shim the springs to tighten the diff. The diff has never been measured for the breakout torque, but now it was 25ft.lb, I want to aim for around 75ft.lbs.

The breakout torque is measured across the two output shafts, here one output shaft is held by a bar pressing on the workbench and a torque wrench is used to measure the torque on the other driveshaft. The torque wrench is slowly turned up until the diff starts slipping rather than the wrench clicking at the requested torque.

Removing the diff cover, shows the LSD.

The LSD is removed and dismantled, revealing the clutch plates and the spring plate.

Two of the clutch plate splined to the output shaft are back t back so as they have no movement relative to each other, this is where I added the shim on both sides, cut from an old oil can.

Adding the first shim the breakout torque was raised to 45ft.lb, so I doubled the shim thickness but the LSD was locked solid. I got out my engineers shim plate and trying a shim at 1.5 times the thickness of my first resulted in 65ft.lb

While the panels are away, we play…..

We reached our deadline for sending the panels to the painter. We didn’t get them completely finished, the door skins were only just held on and the lower skin repairs were given to the painter in a state that he needs to do some panel beating before he’ll start the painting preparation. Are need to keep to a schedule is greater than the want to do everything ourselves.

So the panels were put into a van and taken to the painter

And the car put into the garage naked; there I’ve finally posted the bare P6 picture

A few days later we started into the mechanics and removed the rear suspension to tighten the preload on the 4HA Jag diff. The preload had never been set and for motorsport usage the preload should be much greater than a road going Jag. I’ll aim for 75 ft.lbs. Here you can see the amount of muck around the diff and in the brakes, big clumps of cow stuff.

Good to see all the fabricated parts are holding up well, the only thing we can see not up to the job is some welding around the damper mounts. The lower arms will be cleaned and the weld repaired. Boy is this thing heavy.

And here’s more detail of all that mud.

We also found a lot more rust in the sills so it was a rather frantic day.

I can’t help look at this gap between the diff and the boot well and think of an anti-roll bar; ‘Watch this space’.

Getting ready for paint.

This weekend was the last for repair and modifications to the Rover P6 panels, before they are removed and left with a painter. We have done a fair amount of work to the chassis itself, removing the lower D pillars which wrap around the front edge of the rear wheels, to provide space for wider 15″ wheels and corresponding wider tyres.

The rear door frames have also been modified to continue this extra space for the larger wheels. Here you can see the extra triangle formed on the inside of the door.

The two good (un-hit) spare wings we had, have modifications limited to the moving the forward mounting tabs. Removing the lower D pillars also removes the lower wings mount. These were relocated higher up both on the D pillars and the wing.

The rear valance has been made more suitable for the car, by removing forward pointing corners which enjoy grabbing the grass and rocks as they pass under the car this continually bent the valence corners back.

Most of the work was in repairing the door frames, one was in terrible state with the aid of a welding chair and a lot of Mig gas the frame was made good and the door skin replaced.

The other panels still required work, but not as much. The other big area of repair was the rear jacking point and the sill, D pillar interface. Here on both sides the rot was getting bad, we think due to the bodging of a repair years ago, this was more moisture trapping fiberglass than sound metal.

So tomorrow will finish off the jobs which I listed:

Front door lower frames tweaked; corners cut and bent to be inline with the rear doors.
Front door lower skins attach.
Rear door skins need trim holes drilled.
Prep Rear deck.
Driver Sill cover; Shorten and move jacking point hole.
Bonnet, remove Rover badge.

Then pack it up and send it off to the painters. We are leaving the panels there while we apply protection to the rest of the car and spray can paint the Brown parts on the shell.

With only four weekend left to work on the car until the Irish Classic Retro, we still have a lot to do, but it will work out OK one way or another.
