Yeah, I know...I'm a Ford man too, and Toyota.
The whole LR is well put together, like someone thought enough to design it to be worked on easily.
That's hard to come by

 

Yes
There is a how to with pictures
on the oil pump replacement

 

I wrote a super in depth one. I'd post a link but I'm on my phone. Just search timing chain oil pump write up and you should be able to find it.

 

Its literally American, though; not just alike. The engine is buick designed originally. That's what he was referencing I believe.

 

Hey buddy, I had a tick a couple years back and it ended up being my purge valve. put your hand on it and you'd notice. Maybe not your deal. Just throwing it out there.
Its a cheap easy fix.

 

Small block pushrod v8, close enough.

 

That, and also Buick/Chevy are sister companies.

 

I had the dreaded loud tick after the engine warmed up. Very quiet when cold or when RPM's increased up around 1,800-2,000. After reading everything I could find and fearing a slipped liner I double dosed the fuel with a high PEA content complete fuel system cleaner (Gumout)...there are a couple with high PEA percent (google it). Also, I drained the oil and flushed with 5 quarts of high quality transmission fluid..15 minute idle. Drained the ATF, did a complete OC with new Mobil-1 10w-40 and Mobil-1 filter.

I drove Disco 300 mile trip and haven't heard the tick/knock sound since.

Hope yours is that simple to fix

 

^^^ That is why many of us use an oil made for diesel engines with detergents and high ZDDP levels, it does that for you while you drive.

 

Thanks for the tip...your preferred Brand & viscosity?
