What does that actually mean though? I had a Citroen BX 1.9XUD with the following running in instruction "do not exceed 4_000 (four thousand) RPM for the first 600 miles".

That engine had a governor that cut in at 4_600 RPM.

Don’t blow the bl00dy door ms off, as one Michael Cain once said 😛

I’m layman’s terms …..no redlining it. But I didn’t need to say that really, did I!

Quite the reverse; the line was "You're only supposed to blow the b100dy doors off!"

Hi kenOneil, funny you mention a Citroen Bx, my lade Dad had two new ones, first a burgundy red 1.9rd with the rocker switch for indicators and rolling drum speedo, then a grey  1.9 rd with normal switch gear, lovely cars.

Yeah, I’m getting there thanks. One more hurdle to overcome then the rest is down to me  

 

No need to change the rockers if they’re not damaged, but will definitely need to lap in whichever valves you want to put in the new head, and I would 100% use engine assembly lube as new parts are going in. 
 

If money is no object, why not replace it all, including all the various bolts, gaskets, nuts etc. 

 

I would run the Engine for a week then change the oil, making sure it’s given a few heat cycles and not extract the urine with revs during the first few days. 
 

Not an overly difficult job if you have the tools for removing the valves etc, but good luck 👍

Spent enough on the new head allready!
