Thread: Series 3 6 cyl Fuel

1. Any petrol that is on the market Just adjust the ignition timing to suit

2. No. All Rover IOE engines have hardened steel exhaust valve seats

Just remember to adjust your exhaust valves often on these engines, they need a bit more TLC than some.

Maybe not 'adjust' but certainly 'check' regularly and adjust if required.

A colleague who has a Rover 3Litre car has a theory.... people run them a bit lean to increase fuel economy and then find the valves burning out regularly. If anything it wants to be a bit rich. That reminds me I must chase him for the Weslake head he promised me....

Exhaust valve clearances are a PITA. You can do it without removing the manifold (which would cost you gaskets every time). I managed it by removing the dipstick tube, wrangling the tappet cover out and hanging upside down.

What does IOE mean?

Inlet over Exhaust.
Overhead inlet valves, side valve exhaust valves.
Sometimes called an 'F-head'

Exhaust valves are in the block.

Inlet valves in the head.

Could be something in that. Cookey also thinks laziness around checking and adjusting them doesn't help - he never saw a burned exhaust valve on one in the Military when he worked on them, only in civilian life he saw this. He thinks that people look at the service schedule and say 'it'll be right till next time' and so on until it's too late. In the Military, if it said check and adjust exhaust valves, that's exactly what got done.

Wish he'd get on here more, but I know he's very busy at the moment, he's a wealth of knowledge on these engines.

Thanks guys, best I be getting myself a manual then!!

Colin,
the Chiropractor's bill would be more "exy" than the price of the gaskets!

Cheers, Mick.
