Re: 4.0 V8 won't rev

Afyer a lot of thinking, checking we found the problem.
Autobox caused all the trouble...

Shifter 'pin' was not in the valve body causing the box was in drive and also the park pal was engaged.

Why do you need to select between the tanks? Couldn't you just T them together and solve your problem in a simple way? If you don't do serious off-road work, why don't you consider relocating your pump to the same level as the bottom of the tank and run a longer line. It doesn't have to be right at...

Thanks for the information, didn't know this was gravity fed :oops: Pump is mounted above the tank, probably 30 - 40cm above the top of the tank. What type of pump would you recommend to use for this application, low pressure? I have to fit it after my 3way valve to get the fuel out of both tanks. A...

We had to change the fuel system to a hig...

Do the injectors need overhauling? Again, I'm not convinced fitting an non standard cam will be of any benefit. Although replacing a worn out one will. engine didn't run for a few years. So I want to make sure everything is good and Ok. will let the injectors test, if needed overhaul them. Not that...

My feeling is BMW with the Thor spent a great deal getting the best they could at low to medium revs. At the expense of top end. If you want to get a better top end the simple way is to go back to the earlier plenum - which was originally designed for car rather than 4x4 use. Trying to modify a Tho...

Hi I know a 4.6 would be better but I have a 4.0l at the moment, and I want to keep this a "low budget" build. If the 4.0l dies then I can search a proper 4.6 So could anyone help me with my questions above? And for the buggy is an auto gearbox all the way to go. No clutches to burn, auto is the bes...

throttle body thor

Hi,

I've installed a 4.0V8 with a thor mannifold in my offroader, now I saw that the cooling water runs true the throttle body.

Is this usefull or why is this?

And can I remove this, as in my opinion the risk for leaks is larger.

Thanks for the information!

Regards
Alain

So I think you must use the 4.6 pickup pipe. The hole in the block should be open, and I believe that the oil gallery at the timing cover end is blocked off by the casting. Chris. thanks! I only blocked the 'old' pick up hole. But when it is also blocked at the timing cover it shouldn't be a proble...
