No specific tappet noise at the moment. I have no service record so can't say when they were last done, if ever.

Any hints or tips for doing this?
 
My advice to anyone who asks a question like this is leave well alone until a competent person "holds your hand", on job practical experience is worth a thousand explanations.
 
Its fairly straightforward on the 43, you need to remove the 3 rocker covers, then you need a cranked 14mm or 9/16 ring spanner, screwdriver,feeler blades with an angled tip if poss, and a 24mm socket on a short extension and long bar to rotate the engine on the crankshaft pulley nut, I used a 24mm sparkplug socket.
The firing order is 1,5,3,6,2,4, so when No1 valves rock adjust its paired cylinder No6, so the sequence is,
rock adj
1 - 6
5 - 2
3 - 4
6 - 1
2 - 5
4 - 3
The clearance is 0.40mm or 16 thou and can be done hot or cold, shouldn't take more than an hour if you have good access.

That takes me back to the first days at college studying engineering, "always remember the plus 1 rule" I was told. Stuck with me for the last 30 years (where has the time gone?).

Perhaps I should have said that I have adjusted tappets before. I think the first time was on a Ford Consul in 1967.

Just looking for advice specific to this engine.

That's great. Thank you.
 
I seem to remember that you need extra long sockets to get onto the rocker cover nuts because they are recessed. Someone may know the size. Also my crankshaft nut was 21mm but I have heard others say 24mm. Odd but true.

Yes, I noticed that. Fortunately I've got a box spanner set that fits. Should the three rocker cover gaskets be replaced or can they be re-used?
 
They can be re-used, just take them off and dry all the oil off and clean the groove where they sit so they hang in there when you replace the cover. I use a 10mm 1/4 drive socket as the 1/4 drive extension will go down past the injector pipes.
In 20 yrs of servicing 100's of these engines I have only replaced two gaskets, they are very tough and don't break up, you'd have a job to snap one by hand!

Given they cost under £8, I can't really see the benefit in not replacing.

The boat is not going to sink because of it, but you do risk a minor oil leak, and having to take it to bits again.

Also when you take off the cover it might be OK or it might come away in bits. If the latter then you won't be able to put it back together again!

Replace it.
