Re: Camshaft Help please !
Then that might work. I wouldn't go for the H200; it's too tame in my opinion. I think the Viper Stump Puller would also be suitable. It's not quite as powerful at the bottom end, but it can rev a bit better. But that only makes sense if you drive fast. The H180 can handle the short sprint, too. Do ...

Re: Camshaft Help please !
Hi Nige, I have a 4.6-liter with 10.5:1 compression. I use the Kent H180, but with two SU carburetors. The engine has enormous torque from idle and drives very well. The car is a heavy 4x4, so it's not really a sporty car. But the torque surges suit the car well. What car is your 5.2 engine in? What...

Re: 3.5 RR classic cooling issue
The main bottom hose (outlet) from the the radiator (the one that goes to the water pump). Has a 'T' in it, this 'T' goes to the bottom of the tank. As it is, everything is working perfectly, apart from the fact that the tank gets hotter than I'd like, I think it's not helped by the fact that the t...

Re: 3.5 RR classic cooling issue
The correct answer is: # 1x Small hose from the carburetor dome to the radiator. # 1x Small hose from the radiator to the lower expansion tank connection. # 1x Overflow from the upper expansion tank connection to the outside. https://up.picr.de/49979996mw.jpg What do you mean by: ...bottom radiator ...

Re: 3.5 RR classic cooling issue
Hello, I think your design won't work correctly. As we all know, water expands when it gets hot. But when it gets cold, it contracts again. We also know that water begins to boil at 100°C. It's important to note that this only happens at typical atmospheric pressure. In the context of cooling system...

Re: 1990s Range Rover 4.6ltr V8 Timing failure
There's no reason why a wandering camshaft should wear out the worm gear like that.
I'm sure it was the distributor gear.
The worm gear will wear out again after a similar mileage.
Best regards,
Frank

Re: Does anyone know how to simplify a Gems 4.6 p38a cooling system for a classic car?
Oh yes, about the expansion tank. My description referred to the typical Land Rover tank. The Volvo one certainly works the same way. The inlet here is only from the bottom.

Re: Does anyone know how to simplify a Gems 4.6 p38a cooling system for a classic car?
That looks good, though. Are those larger funnels?
The thermostat should open at 82°C. The P38's only opens at 88°C, which is too high and bad for the engine.
Does the engine have T-liners?

Re: Does anyone know how to simplify a Gems 4.6 p38a cooling system for a classic car?
Exactly! The expansion tank has no return line. A hose leads from the highest point on the radiator to the expansion tank. It does enter at the top, but there's a pipe inside, so the line ends at the very bottom of the tank. If there's air in the radiator, it moves into the expansion tank and bubble...

Re: Does anyone know how to simplify a Gems 4.6 p38a cooling system for a classic car?
I'm not entirely sure, but I think the P38 has a smaller hose vulcanized onto the inlet hose that leads from the radiator to the water pump. This is the return line for the heater/heater valve. The line to the heater core comes out of the rear intake manifold. The heater control valve should be a 3/...

Re: Rover V8 quad Turbo
Hello, I got my hands on a Rover V8 ALBERT Turbo years ago. In similar condition. https://up.picr.de/35696600dq.jpg https://up.picr.de/35696863xi.jpg https://up.picr.de/35696919ph.jpg But four turbos seem a bit much to me.

Re: More Questions on Camshafts (sorry !)
Hello Nige, The big question is, what do you want to do with the car? Do you want it to have everyday handling, or do you want to blast the car around the track at the rev limit? Personally, I love it when engines have plenty of power from the bottom of the rev range. I'd install a Kent H180 or a Vi...

Re: 1990s Range Rover 4.6ltr V8 Timing failure
Sure, if more load is added, it goes even faster. The engine in the pictures above only had the standard spring in the oil pump.
The basic problem is the poor quality and excessive hardness of the aftermarket distributor gears.

Re: 1990s Range Rover 4.6ltr V8 Timing failure
Hello everyone, I'm pretty sure it's not the oil pump. The problem and the cause is the gear on the distributor shaft. The gearing is poorly made and relatively rough. That wouldn't be a big deal. It would wear in after a short time. But! The gear is also much too hard and practically doesn't wear o...

Re: >> ...does anyone know this camshaft? Rover V8 <<
Thanks,
I took a look at it. Unfortunately, the valve lift isn't included.
I'll try to measure the timing. It seems to me that there is no standard specification as to which cam or valve lift they are specified for.
Does anyone have any information on this?
Regards
Frank
