Re: 3.9/4.0

No - the 4.0 is a thicker crank with larger journals.

Re: Rover V8 3.9l power steering pump

A shame you could not keep your original Stag engine as most of the issues have been sorted these days.

Re: electric water pump

I am with Chris - I would be looking for the cause first - electric water pumps generally flow a little less than the equivalent belt driven unit. On your temps, while 105c is getting a bit up there, 100 is about right. My 4.6 runs at about 98. Chris - on a side - what ECU are you running on that en...

Re: Rover V8 starter motors

The starter from my mid 70s low comp 3.5 now runs my hi comp 4.6 no issues - just bolted straight up and no issues turning the engine over.

Re: Are 4.6 Internals Forged?

Nothing special about the construction method of the 4.6. Basically the same as any other mass produced aluminum V8.

While specs might be different, construction and metallurgy is basically the same on all standard Rover V8s.

Re: Engine number

A P38 will have either a 4.0 or 4.6 engine - neither of these start with 47.

I think your original story about the Chimmera is most likely but TVRs are exceptionally rare in Australia.

Re: Engine number

47 series numbers seem to be either Morgan or TVR engines - the later may explain it being 5 litre. https://rimmerbros.com/content--name-Rover-V8-Engine-Numbers https://www.gomog.com/allmorgan/V8enginenumbers2.html https://www.v8register.net/FilesV8/V8%20engine%20number%20reference%20R7%2030.11.07.p...

Re: Rocker Gear lubrication

Are the pedestals on the correct way - if not the can block the oil feed holes.

From the official Land Rover V8 engine rebuild manual. Engine Numbers without suffix B Uses an external gear oil pump driven by the distributor drive shaft.

Re: 'Thor' stalls sometimes

As mentioned - in the Thor system the regulator is built into the fuel pump in the tank so the pressure remains constant and is not controlled electronically.

Re: 'Thor' stalls sometimes

From what you have said I would be looking further into the idle speed control valve. This is based on the engine is working Ok in other situations and only starts to play up in situations where the idle speed control valve comes into play.

Re: HELP - FIRST CRANK - NO OIL PRESSURE

Keep it simple. And I repeat...you're making this far more complicated than it needs to be. I agree - this thread has been going on and on - keep it simple. Start the engine - if oil pressure comes up immediately then great - if not switch off. However before hand - fill the oil filter, fill the oi...

Re: HELP - FIRST CRANK - NO OIL PRESSURE

Take the oil pressure switch on the side of the timing cover out - it is the first "outlet" downstream from the oil pump - if the oil pump is picking up and pumping it will squirt out there - crank for 30 secs and see - noting that with the switch out nothing else in the engine will be getting lubri...

Re: HELP - FIRST CRANK - NO OIL PRESSURE

Anyone know the function of these (do they tap into the oil way?): Do not touch those - they are the cross bolts for the bearing caps and no they do not go into an oil way. My 3.5 with a cam shaft driven oil pump sat for 10 years and it did not drain back and got oil pressure as soon as it started....
