[16v] euro intake cam install



Hey list,

I've received my euro intake cam from Andy Holmes (thanks Andy!) in the UK
and have some questions for people who've done this before..

First - can this cam be used with a catalytic converter or is it
-necessary- to remove the cat in order to prevent it from melting as
suggested by Andy and several other sources? I'd like to keep my cat if
possible for the reduction in emissions and exhaust-quieting value alone..

Also, is there anything I need to know for the install? Basically just pop
off the intake and valve cover then loosen and remove the cam bearing caps
gradually (is it 1/8 turn at a time?) and remove the old cam. Then just
bed the new one in and throw it back together? Do I need to use assembly
lube? What about new hardware - are any new parts needed besides the valve
cover gaskets ?

Bradley Peet mentioned that it is necessary to either remove a bolt by the
end of the head or remove the exhaust cam in order to remove and install
the intake cam.. any comments on this?

Should I change my camshaft sprocket oil seal while I'm there? (or is it
not necessary to remove the sprocket for the install..)

I'm also doing another repair either before or after the cam install - for
some reason my crankshaft sprocket is installed lopsided and is actually
rubbing on the block causing a really ***IRRITATING*** squeaking noise and
I can't take it any longer. So I'm taking the sprocket off (even though
it's like a 190 ft/lbs bolt) and re-installing it evenly with a new bolt
and spacer that I ordered from the dealer. Any tips for getting this bolt
on/off ? I don't want to snap off the head or something like that. That
would be a major PITA. I already had the sprocket "slip" while I was
tightening it 2 years ago and ended up schmuq'ing the molded key inside.
At the time I was able to just get a new sprocket and carefully file the
notch in the crank to "repair" it. I determined that it would not likely
slip because the damage was not to the side of the notch that the key was
"pushing" on .. had the engine turned the opposite direction instead I
probably would have needed to replace or machine the crank/block.

I appreciate any comments or info..

Thanks,

-Toby
