Re: Taps and dies

For the engine I find that M6x1, 8x1 and 10x1.5 cover just about everything, and for the rest of the car I use 1/4, 5/16 and 3/8BSF. Not all taps and dies are equal; I buy a good brand from a commercial supply house or MG specialist, and am usually happy. There are different types of taps, though: t...

Re: M6 Fine Bolts?

When cleaning the threads do NOT use a shiny, new, crisp tap, as it will remove enough metal to weaken the threads. Use either a dedicated clean-out tap, or an old tap that has been vigorously sand-blasted. I offer this suggestion because one Australian owner bought and used a new tap on his head st...

Re: M6 Fine Bolts?

I think M8x1.0 bolts are used to support the engine, not 6x1. The length of the bolts will be determined by the length of the bolt tubes on the stand head, but if you can only find longer bolts, you can always use washers to reduce their effective length. It's awkward, but do use all 4 arms for supp...

Re: Second gear from standstill

A TC box is a strong box - that's why TD racers used to retro-fit TC gearboxes - they are such better units than TD gearboxes. TC boxes hardly ever break, or wear out (other than the flimsy rear transmission mounts, which break all the time, and need to be reinforced). To my mind, first gear is desi...

Re: TC front brake cylinders

Aluminum corrodes nicely - I send my old iron ones to Mark Frappier of Agawam, Massachusetts, and have them sleeved in stainless. They last forever. He cannot do TC master cylinders, due to their construction.

Re: TD oil pump to TC conversation

So the question is whether anyone has ever modified a late TD/TF horizontal-filter oil pump to use a vertical TC/early TD oil filter? If anyone will know, it will be Butch Taras.

Re: Late TD/TF Oil Pump on TC

Steve - as I remember (it's been some time since I did this, with the later spin-filter adapters so readily available): 1) remove the bypass valve from the block 2) plug the block's oil inlet where the external filter pipe attaches 3) remove the oil filter bracket, and 4) put in shorter bolts to fil...

Re: Whose TC

If it is any help, XPAG9404 was originally supplied in TC8771.

Can you give us any further information, or photos? There are indeed VERY convincing T-series scams out there, so do beware. Any further information can help us determine the nature and status of the car.

Re: TD piston replacement

I hate to tell you, but you are really just putting a band-aid on your engine by JUST doing rings. If you have bad rings (and your readings do indicate that - I am suspicious of anything below 145# dry), there are so many potential engine weaknesses associated with your cylinder wear. The rings are ...

Re: Wire wheel testing

Perhaps a better title might have been "Wire Wheel Replacing." I have tried straightening and re-lacing wire wheels, but have found that they are far more trouble than they are worth. Stainless spokes alone cost nearly as much as a new wheel, and straightening requires a 100-ton press. I now buy new...

Re: TC or TD engine?

Not quite, Thierry - the early TD used a cable clutch linkage that was replaced by rods; the remains of both the cable base and the pivot or fulcrum pins for the rods will be on either side of the sump. The TC used a chain hooked directly between the pedal and clutch operating lever, so there will b...

Re: TC or TD engine?

Steve is right about engine tag location. It does appear that someone has grafted the TC tag onto a later block. Many - not all - later blocks had the engine number stamped on the block itself, across the top of the plinth. The digits are often painted over, but scraping may reveal them. There is no...

Re: Brake Master Cylinder on TC

Remember that oil leakage at the rear hubs is the mail reason why the rear brakes stop working. Get the hub nuts with integral seals.

Re: Brake Master Cylinder on TC

Using DOT5 silicone brake fluid in a new TC master with a bronze bore (or a more expensive cast bronze master cylinder and bronze wheel cylinders) is a sure way never to have brake failure. A dual master cylinder is not of much help unless you truly isolate the front and rear brake systems as two se...

Re: 'water on the head', no not that one, the cylinder head!

The factory torque recommended for head studs is 50#, which is the limit of the materials they used - fairly soft. Even at that there can be considerable stretch, causing uneven torque. The ARP head studs I have made and sell, of superior materials and with rolled threads, are torqued to 60#, and ar...

Re: Brake fluid

Silicone brake fluid is another of those subjects on which you will get polar opinions. I have used it for years, and strongly recommend it IF the system is entirely rebuilt/replaced, and IF you flush the system with alcohol first. Dot5 does not like air bubbles, so agitate as little as possible and...

Re: 'water on the head', no not that one, the cylinder head!

Chris - washers are not helpful on T-series engines, unless you have an aluminium head or unusually high compression with an iron head. Are what you used hardened steel, parallel ground washers? If not, they could well yield incorrect torque figures. I would re-torque the head every hundred miles fo...

Re: 'water on the head', no not that one, the cylinder head!

The head stud holes are blind holes, and do not lead into any water passages. That means you have water coming from a water passage in the head and/or block, which means you have a sealing issue, probably based on torque. Did you replace the head studs? They are an object of considerable stretch - t...
