Many people fail to notice a hard and compressed rubber seal and even put in a second one. If there is no sign of leaking - it should be OK but the 3 Litre runs at quite high pressure (or should do) so I would sort it
Its easy to remove again and you will not loose much oil.
I always unbolt the whole housing anyway by removing the 2 5/8ths AF bolts - its the easy to refill the cannister with fresh oil to avoid running the bearings and you can ensure the rubber seal is correctly fitted.
By the way this should be posted on 3 litre Mechanical - this is Board Operation Queries
Having just solved the fuel filler problem on my 'new' P5 saloon, I've been driving it every weekend and noticed the tappets are quite noisy A) what oil should I be using (in case it doesn't have enough to go round), and B) does the oil filter have a paper interior, and could this have deteriorated and blocked one of the oil-ways? The reason for the last question is a friend had a similar problem with noisy tappets on his Alvis TE21, and it turned out some of the oil lines were blocked with gunk from the filter itself. Fortunately his garage spotted the problem before he caused any serious damage! And can anyone recommend a specialist in/near SE London/NE Kent? Ian Conway
Thanks Phil, you are a gent as ever The car has had v little use in the last 5 years, just enough to keep everything ticking over basically, but obviously parts like filters can still deteriorate. I shall contact Graham the parts man and order two straight away! Thank God for the forum, eh? All the best Ian

;)You are welcome - the roller tappets on the P4/P5 engine are very reliable but eventually so cause camshaft wear which can cause a knock akin to a worn tappet after high mileages/oil change neglect. It will go on virtually for ever in this state though but does spoil the silent tickover.
This engine relies on loads of clean oil sloshing around and is also designed to burn some.
Even low mileages leave acids and combustion debris in the oil which deteriorates (or the addtives) just standing there. This is why its best to change it for new after 18 months as both filter and are cheaper and very easily DIY changed.
As to the tappets these are easy to adjust except you will need new gaskets and the inlets have to be done hot. It makes no difference to the exhausts except I do them cold to avoid burning my hans/arms on the exhaust manifold. Make sure you use a first class 1/2 AF ring spanner or siocket on the locknuts as these can be very tight and are easily rounded by careless handling/poor fitting spanners. ;D
