V8 costings
Hi all
I'm slowly rebuilding a Rover V8 and i have come to the bit where i need to worry about replacing the cam. The old cam isn't too bad but
the timing chain is as slack as a you know what. I have seen several Cam kits advertised by RPI and the like, but these cost nearly £300 so my
question is can you just buy the cam, a new chain and use the old hydraulic tappets or is this a recipe for disaster
Thanks
Julian Brewer

never reuse old tappets with a new cam unless they are roller followers (you cant get these for a rover v8) as the old followers will wipe the new cam
out in a few hundred miles.

Yeah as tim says, always replace cam and followers together. I've seen some pictures of almost perfectly dished (edge to edge) followers and
rounded cam lobes. The engine barely ran, but once the cam gear was replaced it was fine.
Timf, any idea why roller followers aren't available?

Julian,
If the cam/followers are ok, just get a timing chain and gears. Three items from Rimmers is about £35.

Ouch!
I see your point!
Hopefully ours won't need any work at all but it's nice to know that the chain and sprocket aren't much. How much for the duplex
kit?

Julian,
While you're in there are you going to replace the oil pump? I think it is quite cheap. Just make sure you prime it with the magic tool or pack
it with petroleum jelly so that it can prime itself. Sorry if you alrady know this but better safe than sorry...
Cheers,
Craig.

Hi Craig
Yes i have had the oil pump apart for a visual inspection and it all looks fine (no major scoring or wear etc) I have read about packing the thing
with Petroleum jelly but i have no idea what that is. It sounds like something you get from Boots or is my mind going of track here. The last thing i
want to do is go to my local motor factors and ask for a bug tub of KY. That would give them a real excuse to call me a MERCHANT BANKER!
On a more serious note dose packing the oil pump with said gunk not clog the oil filter on start up?
Thanks again

I think KY and Petroleum Jelly do have some things in common but I wouldn't use the former in my oil pump... 
As far as I know the petroleum jelly will break down very quickly once it heats up and will be diluted completely by the oil. I don't know if
there are any issues with synthetic oils but mineral oils should be fine and IIRC most folk recommend using a good quality mineral oil after an engine
rebuild anyway. You should change the oil soon after a rebuild as there are usually contaminants which clog up your filter and degrade the oil quicker
than normal to begin with. If you are worried then prime the oil pump with the electric drill method. This involves driving the oil pump which is
accessible through the aperture that the distributor comes out of. Mark the position of the dizzy and remove it then make up a tool to attach a drill
to the little slotted drive thingy at the bottom of the aperture. You could use some 13mm round bar with a slot cut in it to suit the drive slot. Then
just spin it up in an electric drill until you see oil weeping from the rocker shaft oilways (rocker cover open of course). Refit the dizzy and align
the mark you made to get rought timing. You can buy a tool from Rimmer Bros for this if you don't want to make one and this is a recommended
procedure by the way...
Also, with your new cam, did you get a bottle of cam lube? I got this with a piper cam kit for a mini a few years ago and it is a very sticky thick
lubricant which is reputed to protect the cam in the early stages of its life when the followers and cam are bedding in. Mine was red and reminded me
of the raspberry sauce you get on ice cream. Just pour it liberally over the camshaft and followers as they are installed.
HTH,
Craig.

You mean they're both used as sexual lubes by people who don't know better?
(my ex worked in a proper sex shop, i.e. not ann summers, and one of the things I aquired was a bee in my bonnet about people using bad stuff for
sex)
sorry about that.. back to engines

I don't know quite how to respond to that so I won't...
Don't worry, I only use it on my feet when I play squash to avoid blisters. (Vaseline that is)
As you said, back to engines...
Cheers,
Craig.
