Level of 3.9 litre V8 in Chassis

**Lionelgee** · 31st July 2023, 08:46 PM

Hello All,

Can anyone with a Range Rover 3.9 litre V8 let me know if the engine is level when mounted in the chassis? Or is the engine high one end? For example, if you put a spirit level down the length of a rocker cover is it level? Or is the spirit level high towards the front of the motor and low towards the gearbox? Or high at the gearbox end of the motor and low towards the front of the motor?

I just made an engine dolly for a 3.9 litre Range Rover V8 and since I bought the bare motor after it was removed from the donor I do not know how level the engine was mounted in the chassis.

I will post some photographs of the dolly I made and some dimensions.

In the near future I will convert the dolly to an engine test stand. At the moment I can easily push the engine around on four castor wheels. The dolly also provides a stable environment where force can be applied while dismantling the motor without worries of things tipping over when using an engine stand. I used 200 mm x 50mm 3m Treated H4 Pine Sleeper for the dolly's main frame. Plus the height of the castors so everything is close to the ground and sturdy.

Kind regards
Lionel

The problem is you can't really use a spirit level to define the level of the engine relative to the chassis in this manner because most vehicles will have slight level variations of the actual chassis.

If I were to measure the (spirit) level of the engine in my 2 V8s they would both show different readings because one of them the chassis is front down, but the other is rear down.

If you use Bobs' measurements(as another random owners measurement) and his vehicles are modded in some way, with suspension or winches or bullbars .. then he'd have different values as well.

You'd need to measure the level of the engine relative only to the chassis itself. That is, get measurement of the front of the rocker cover compared to the chassis, then do the same for the rear end of the cover relative to the chassis too.

But a quick eyeball of my 2 D2 v8s, it does look like the V8 has a front up appearance(relative to the chassis, that is).

Can’t remember ever seeing a north/south laid out engine in any car that didn’t have a bias towards a rearward slant to accommodate the natural layout of the drivetrain.

I have a 3.5 fitted to an 88 RRC in my shed if you would like to measure it ?

G'day Paul,

Now that sounds like a very good plan, Paul! What afternoon would be good for a visit? Oh and which of your sheds by the way?

Kind regards
