Any reason the vac pump can't be removed completely? does anyone make a blanking plate for it?

--- Quote from: "Timbob" ---Lochgellys a fair treck. Hope you dont mind if i see how my misguided fumblings go this weekend before taking you up on your kind offer. Please dont think that im doubting your opinion/ knowledge, but im keen to know how you fit these valve stem caps on the off chance the repair costs nearer a tenner than a hundred.
Thanks, Tim

as i said earlier the valve clearances woulda been huuuuuuuuuuge if it were the valve stem caps,easy enough to check, unbolt the rocker cover, unbolt the rocker shaft & have a look.......
if they are missing it will look like a polo on top o the valves,

Mr. Team, today I chanced upon an old retired engineer who reckoned 99% that it was indeed the vacuum pump. Cunning old [!Expletive Deleted!] had a good idea too. As a test/temporary repair he suggested removing it and after inspection, refitting it with extra gaskets to move it slightly away from what ever actuates the noisy thing. What do you lot reckon, sounds sensible to me. Got 3 new gaskets and will give it a go tomorrow. As you said Mr. Team, valve clearances would be way out with duff caps. One guy mentioned cracked caps? Would they make a noise? Also, finding TDC to remove the pump sounds like a right faff, is it possible to remove a glow plug and check the petrol way? Surely it cant need to be super critical, can it? Just out of interest, while I got gaskets at land rover dealer in town, asked price of new pump. £100 from Paddock, £270 odd PLUS VAT! Ridiculous difference. Once again thank you all for your patient replies. I know stuff all bout diesels.

never set one to TDc as all the vacum pump does is sit on a bit o the cam which has a lobe no timing is required of the vacum pump,
TBH you could space the vacum pump out but for the time you spend doing that to identify it you would have it replaced & go back to piece & quiet,
cracked caps would have the same effect as misisng caps as the clearances would be waaay out
mike aitken 4x4 in ladybank keep them in stock & are cheaper than paddocks i think
P.s won best apprentice mechanic 2 years running whilst working for a landy specialist:wink: so i know my shizzle
davidlandy:
if you put more gaskets on would that take the pump further away from the cam and make it even noisier?
