Re: Overheating!

Basically cooling function involves 1. Successful delivery of heated coolant to the radiator 2. Efficient dispersal of that coolant through the radiator 3. Adequate airflow across the radiator to remove enough heat to maintain coolant temperature at an optimum level. Factors affecting: 1. Water pump...

Re: ride height

Jack the car up at the front in the centre of the picture frame so that the front is level. Use a wooden block to protect it. Now look at the rear and see if one side is lower than the other. If so, swap the springs and shocks from one side to the other and see what happens. Similarly, jack the car ...

Re: Need advice on new engine sump.

Expertise, LOL. As long as you have the correct rear seal housing they fit. I put a 4.2 sump on my recent 3.8 rebuild because it looked better that the finned 3.8 sump I had. I did change one of the oil pickup pipes but that was only to fit the bore in the oil pump. The engine originally came with a...

What always amazes me is that a lot of effort must go into making these sumps; just how hard is it to get right??
I agree. The new ones would be individual sand castings. I suppose that they may have made the error in the machining of the top surface. How much did your new sump cost?

Re: Need advice on new engine sump.

My machinist uses a dye solution to find leaks. Fills the sump with it, looks to see where it comes out and then grinds that area out and fills it with TIG.

Re: Need advice on new engine sump.

Despite your experience, it is possible to leak test and repair a sump. My machinist in Australia does this well. I'm sure there will be a specialist welding company near you who has the knowledge and equipment to do this for you. I would recommend you get them to have another go. What I am told is ...

Re: Need advice on new engine sump.

but it was a lot better than one I had bought from one of the usuals previously and had returned because it wouldn’t fit properly. Are they still doing this? I bought a "new" sump for a 3.8 a few years ago from a "usual" and got sent a used sump from a military crate engine from an armoured car. I ...

Mostly the benefit comes at a given rev point, chosen by designing the length and diameter of the primary header according to a proven formula.
Which presumably means flat out for a race car.

LOL. Where I live, if you speed at all you get fined in short order. It is accepted revenue raising. Recently I changed the tyres on my FHC from 60 to 85 profile. Not having had a speeding fine since 1995, I subsequently got 2 in 3 months in the FHC. Because the increase in tyre size made my speedo ...

Re: Window height adjustment

The spacers are there to adjust the frame height and angle relative to the A and B pillars. When refitting a window frame you use them to get the frame to line up properly to the door opening. If your frame is otherwise lined up you should not need to alter yours. You're doing very well; most soft t...

Re: Refurbishing door handles/locks

Good luck. I've tried this on several occasions and have finally given up in frustration and bought new handles and locks each time. The locks are incredibly cheaply made and are very hard to get to work properly again if they are broken. Rechroming the handles looks nice but then you have to get th...

Re: Front Alloy 4 Pots

Willwood, Coopercraft and Zeus I think all produce alloy front calipers. There are probably others.

My 2C worth is to rebuild your existing calipers. They work well.
