Rover V8 lifters
Discussion
I have read somewhere that these are not 'user-serviceable'. While I realise that this means there are no replacement parts available, and I would not want to replace any anyway, I am currently preparing an SDI lump for a rebuild. The crud inside this poor motor was, even for one of these, almost unbelievable. So I decided to strip the lifters and clean them up. I have done eight of the sixteen; apart from spending 10 minutes searching for (and finding, happily) one of the circlips that went airborne, I found the job quite easy and a few of them initially would not budge but a good soaking in petrol and patience was rewarded. Crud had not found its way to the innards, but they were quite gummed-up and I am happy that I have gone down this road. Hopefully the remaining eight will be similarly easy to do. By now dear reader you will realise that (I am a tight git) this is a budget build, but I will resist the temptation to buy cheapo gaskets, having been warned of the likely pitfalls.

I've not measured the lobes Steve, but they look to be in excellent nick. Also the lifter bases are good, and the lifters seem to have been rotating nicely. I was able to draw them all up out of the block; I have seen some in the past that would not come out upwards, naturally they were mushroomed and scrap. All the pushrod, rocker and lifter bearing surfaces are perfect. Although there was a lot of crud in the engine, all the lubrication passages were clear, even those in the rocker shafts.
I will check the cam lobes later (at work just now) - thanks for the warning.

You must be very tight! bits for these engines are pennies really. I would only use new items you dont want to be pulling it apart time after time.
Dead right Neal - they don't get much tighter... On the horizon I may well do a proper costlier rebuild on the original engine next winter. Bear in mind that the lump is in our old kit, replica 1929 Model 'A' which is only on the road for half the year. All good fun for me.Pete
Only four lifters left to do. Checked the cam tonight; all the lobes are OK. I popped it back into the block and the lift is as far as I can tell with the vernier just under .4" (the dial on the vernier is broken and I can't get access to my lad's newer one)so it will do for now.
Thanks for all the advice.

the lifter should be fitted back in the same bores as they now are matched to each lobe, you will also need to use a good lube on the cam/lifter face to stop any scuffing on the restart, proper cam lube is best or somthing like Rocol Anti scuffung paste is a reasonal sub,
No probs ian - I have them nicely laid out and ID'd for each position. They are all nice and free now, and all the bearing surfaces OK. All the engine oilways are clear. The pump is spotless with only shine and no scoring of the teeth. The relief plunger is similarly spotless and free-moving. I take on board the recommendation of a good quality cam lube for the restart - this I had planned in addition to the priming of the lifters, judicious lube of all the moving parts, and the proper priming of the oil pump before the turning of the key...... PS - The vernier I used, while it has a broken dial, gave sufficient indication, using it as a depth gauge with my engineer's rule, while checking the valve lift, that the cam is up to the job. I can see that there is no sign of advanced wear of the lobes. As near as the naked eye can see, lift of fractionally under .4" is as near to .39" as I need to know!
