Hi Mike,
I didn't allow for people who fit the wrong oil pump drive for their cam.=20=

Or the wrong chain on their timing gear. Or fit no rings to their Pistons...=
.
But in this modern world of people who get burnt by coffee, and subsequently=
 sue Mc Donald's, let me add...
You need to fit the correct oil pump drive, appropriate to your 12 or 13 too=
th camshaft.=20
And while, theoretically, not having an oil pump drive engaged with your cam=
 will theoretically mean you can never wear this gear out, be aware that the=
 rest of your engine is now stuffed.  ;-)
Best
Chris
P.S.
I reckon the issue with that worn out low mileage old blokes 100/6 oil pump w=
as actually due to some young buck mechanic who revved the date out of it at=
 every service. Ferris Bueller Salter - I'm looking at you!!!! :-)

5=E2=80=99s, and also 100/6's. I=E2=80=99m not sure whether or not it was us=
ed in any 3000=E2=80=99s, or when it changed. This camshaft is relatively ea=
sy to identify, as the gear closest to the back of the camshaft, which drive=
s the oil pump, has 13 teeth on it. So it is the same diameter as the distri=
butor drive gear on the camshaft =E2=80=93 both 13 teeth. Usually, these cam=
s have beautiful lobes and have never been reground. Because they came from a=
 low mileage sedan.... That's why racers regrind them & use them...
>> The other camshaft, typically found in later C Series engines and later 6=
 cyl Healey's, later Wolseleys  etc. (I'll call Healey cam) has 12 teeth to d=
rive the oil pump (and still 13 to drive the distributor). Easily identifiab=
le because the two gears on the camshaft are different diameters. It effecti=
vely drives the oil pump 8% slower than the earlier "sedan" cam at the same r=
evs.=20
>> So I'm guessing your "souvenirs" all have 12 teeth cam drives. Just like a=
ll those that blew up with the same symptoms at Bathurst in 1998 and 1999.=20=

>> Denis Welch explained to us, face to face, the lack of lubrication to the=
 cam/ oil pump gear drive issue, at Bathurst in 1998. He even drew a picture=
 of how you can tap into an oil drilling in the block, that you thread a pie=
ce of brake line into, to squirt oil directly on the camshaft/ oil pump gear=
s, to keep them lubricated. But he also said - NEVER run a 12 tooth cam/ oil=
 pump drive cam over 5,500 rpm - irrespective which oil pump you use - becau=
se 5,500 rpm on that cam is driving the oil pump closer to 6,000=20
>> If you use a standard Healey crankshaft, (so you aren=E2=80=99t going to "=
regularly" rev it over 6,000 rpm) and fit an upgraded oil pump (e.g. the Den=
is Welch hi volume pump) with a sedan 13 tooth cam - you will have huge oil p=
ressure. Because the =E2=80=9Csedan=E2=80=9D cam is driving the oil pump 8.3=
3% faster than the =E2=80=9CHealey=E2=80=9D cam at the same engine revs. =20=

>> And if you rev the engine with a =E2=80=98sedan=E2=80=99 cam at 6,000 or m=
ore for any prolonged length of time, the oil pump gear on the cam will stri=
p and you'll have no oil pressure at all. Because although the engine is pul=
ling 6,000rpm, the oil pump is being worked as if the engine was running at 6=
,500rpm =E2=80=93i.e.  8.3% faster=E2=80=A6 and if you were pulling say 6,40=
0rpm =E2=80=93 the oil pump is being driven as if you were pulling over 6,90=
0 rpm.....
>> The cam gear that drives the oil pump on the C Series engine has very poo=
r lubrication (it=E2=80=99s based on the BMC =E2=80=98splash and drip=E2=80=99=
 lubrication theory). There is no pressure fed oil to the two meshed gears =E2=
=80=93 the oil pump drive gear on the cam, and the oil pump drive spindle ge=
ar. So as you rev the engine  harder, the =E2=80=9Cdripped and splashed oil=E2=
=80=9D gets thrown off the gears, and they run dry, wearing through the hard=
ening relatively quickly, at sustained high RPM. This process is all dramati=
cally increased if you are running a =E2=80=9Csedan=E2=80=9D cam, as the oil=
 pump gear on the cam is driving the oil pump spindle gear 8% faster....
>> You also mentioned the steel camshaft retaining plate failures. Denis Wel=
ch also offers a Hardened steel version of this plate, and a Torrington bear=
ing - which together solve the second issue of wear in this area.=20
>> The ultimate solution is the DW gun drilled cam, which makes the camshaft=
 part of the oil gallery, and lubricates under pressure the cam lobes and oi=
l pump drive gear and the distributor drive gear. These didn't become availa=
ble until around 2003.=20
>> We pulled the sump off my engine, and pulled the oil pump, after the nume=
rous Bathurst blow ups in other guys engines from this issue. See http://www=

>> So your concern is valid, Richard, but the missing piece of the issue is t=
he cam gear teeth. Mine is 12. My concern was alleviated after we pulled the=
 pump after 3 years driving and some 20 track days.=20

a>&nbsp;</div><div>So your concern is valid, Richard, but the missing piece o=
f the issue is the cam gear teeth. Mine is 12. My concern was alleviated aft=

 DW pump &amp; Penrite HPR they'll have better oil pressure figures than me a=
