What Cams are these?

Post by bjmullan »

Just stripped my engine and was interested to know what cams these are?

PET shows the following:

Right cam numbers

M >> 0903069 901 105 110 01
>> 0903070 - 0909927 901 105 110 04
>> 0911001 901 105 110 05
No engine numbers 901 105 134 00

Left cam numbers

M >> 0903069 901 105 109 01
>> 0903070 - 0909927 901 105 109 04
>> 0911001 901 105 109 05

then some more part numbers for MFI cams etc

Does this tally with your engine number?

You cannot identify early cams from their casting number, the only sure way is to send them to a cam specialist such as Kent Cams so they can be measured for lift, duration etc.

Just from memory (unless they have been re-ground) the number 901.105.134.0R is a RH cam for a 911T, they have the same number up to 72 T.

Not sure on the other one, but again from memory the number is not from a LH cam from 69 911T.

Hi,

901.105.133.0R & 901.105.134.0R

In case it helps those casting numbers are correct for T cams from 69-73.

I only have cam numbers from 69-73 and could not find a 901.105.109.01, prob pre 69.

Thanks

HI Brendan
the cams you have, 901.105.134.0R is for a 911T R/H and should have a "03" stamped on the end (where the cam nut is), the 901.105.109.01 is a early cam for the L/H side and if it has not been re-ground it is a miss match, as the cam timing for the L/H side is 4.2-4.6 and the R/H is 2.3-2.7,
the L/h cam should be fitted to a 901/01 engine and the R/H should be in a 901/03/13/16/19

Hi Mike. Does this mean that these cam's are incompatible? The damage to my pistons is extensive and looks like pre-ignition. Would this point to the cam's being the problem?

If you want the pair of 2.0T cams I've got Brendan, you can have them for the price of shipping.

Wowowowow. HANG on a minute. So Brendan is not bringing his Mint T- the only genUINly Mint T north of centre Glasgew, to CLM :?:

Would a running carrera 3.o engine help to get that thing and its owner down to France?
