bit of a strange 1,

i recently snapped my cam in half long story available in my resto thread

ive fitted a new head that was from my mate tom scarletts 300bhp s1, now the head was all built up when i put it on, head,valves,lifters,rockers etc along with a vernier pulley,

the pully was not bolted to the cam tho,

now ive fitted it all up and the car runs fine but im getting an oil leak from the end of the cam itself where the vernier bolts on it is not coming form the rubber seal around the cam as there is no oil whatsoever there, its driving me mad as its making a right mess flicking oil all over the show,

here is pics of the vernier,sensor set up all bolted on then a pic with the sensor pick up and bolt removed to show the oil seeping out







is there meant to be an o ring or something there or is the reason its leaking oil because i have not thread locked/sealed it as i wasn't sure if the sensor was in the right place? if was to seal it with thread sealer would this stop it ok

thanks

 

been told there is usally a bearing in standard cams that stops this but a bit of thread sealer/lock will stop it fine so happys days & all is good

 

let me guess? Piper cam by any chance

 

not sure what blank was used mate but no its not a piper, although it was profiled with some of the piper 285t2's characteristics

 

Piper are classic for this......i suppose its all about saving as many pennies as possible though

 

unfortunately thats true mate,

quantity not quality for some firms

 

sadly so

 

I had the same problem when i fitted a new cam to me RSi a while back, couldnt understand why it was doing it but then i was told to coat the pulley bolt thread with loctite before refitting it, no problems since

Something to do with the cam sweating the oil out i was told?

 

what absolute BOLLUCKS lol

The cam has holes drilled through it to help oil flow where the cam runs against the head surfaces, so oil enters inside the same, the better cams inclusive of Ford ones, have ball bearings pressed in to stop the oil running out the end.

Cheap/poor quality ones don't

 

A non-believer eh?

Mine was a kent cam and it wasnt hollow at the pulley end? couldnt see any ballbearings either?

 

Yep i think its a piper cam my mate hase one with the same prob.

 

Where did you get the cam position sensor (trigger assembly and pickup assembly)?
I am putting together a Haltech E6S management system, and would like to use a cam position sensor for full sequantial operation.

Cheers

Perry

 

sensor set up is a FIELD MOTORSPORT design

give them a call on 01245 320 730 and ask for tommy, tell them your after the same set up from the blue mk2 xr2 turbo that they built the engine for
