Hi. I have just got my first Land Rover, It used to belong to my dad. When I drove it home I noticed the temperature gaged was high. My dad did change the gadge before but he said it made no differance. It goes close to the red, but not into it. Also oil has started leaking out of the oil cap.
Any advice. It's a 90 4C SW Diesel aspirated engine 1989. Thanks

Check all breather pipes make sure they're not blocked

Thanks for the advice. I will give it a go. I thought it might have been the head gasket.

For head gasket, check oil and water aren't mixing, Given that the oil looks 'typically black' it may not be that, but a implement compression test will show this, even if it's blown between a piston and an oil way

Years ago my old man had a RRC 3.5 v8, it was forever blowing the V gasket and pushing oil out, change v gasket twice before a friendly landrover guy showed us the blocked 'flame trap breather' on back of rocker cover. No problems since then.

To be clear the cap in your photo is the engine breather it's not the filler cap.

Sorry. Very new to land rovers, and I'm no mchanic, but up for giving it a go. Any advice very much welcome.

Hi Pigsy, I've recently bought the turbo version of the 19J engine (1988 diesel turbo 110 High Capacity Pickup) they are supposedly prone to 'breathing' through the rocker cover vent/oil filler cap, mine was swimming in oil. I have changed the rubber sealing ring on the filler cap as it was worn and leaking as in your picture. Got the seal from John Craddock, think it was 67 pence + vat.
Rocker cover gasket was also split and the dipstick loose where it screws into the block. There is no rust on my front chassis
