Pinto camshaft advise please
Ive just bought an injected Pinto engine. Valve stem oil seals need replacing but it came with new std cam kit, bolts and gasket set so im about to
rebuild the head. Im ideally after something with a bit more power. Ive just been offered a Piper 270 cam.
My questions are;
1. Is the cam for an injected head different to a non-injected head?
2. Can i fit the standard cam kit and just substitute the std cam for the performance cam?
3. Is the Piper 270 cam any good for a Pinto? (very similar spec to Kent FR31 - fast road?)
4. Can the new spray bar be modified to stop the usual problems?
Thanks,
Darren.

pinto cam advice
I'm just rebuilding my Pinto injection engine, unfortunately I had not heard the engine running as I bought a part built kit.
The cam was quite worn but not real bad, I have purchased an FAI cam kit to replace said worn item, the information centre on the FAI web site
(www.faiauto.com) lists the 2.0 & 2.0i as having the same replacement part no.
On my engine the bores & oil pump are well within the acceptable wear limits given by the Haynes Manual, although I have not dropped a shell off
to look at the crank.
The Pinto is prone to cam wear especialy if service intervals are stretched, cheap oil etc. so I'm hoping that it will only need the cam kit, in
the true locost spirit !!
If your piper cam is new I can't see a problem swapping, if its used you really need the follows as mixing old & new will accelerate
wear.
I am not aware of any spray bar mod, I think quality of oil & regular servicing are the key.
Hope this is of some help.

When engine is a runner or as you are trying to start it, you should whip the cam cover off and visually confirm that you have a good oil feed to ALL
8 fingers while engine is turning over/running. If poor or no feed to any one finger replace spraybar until you have a good one. Brand new faulty one
should be replaced under warranty.
Enjoy. 16 Days to go.

you can turn the oil pump over without having the engine running by removing the dizzy and using a hex drive srewdriver attachment without the
srewdriver end in it will turn the oil pump drive ( turn it clockwise ) oil should pour out! hope that is of help, you can buy just spray bars if your
worried about the age or type of it i have a fr32 which is very driveable. are you running injection or carbs?

if you can get old of a "x drilled" cam they are the ones to have, this does away with the need for a spray bar and puts the oil just
where you want it.
the above tip is well worth doing after any pinto re-build, it primes the engine with oil befor you start it, i used to use a cordless drill to punp
the oil around.
horse for course's but i like the piper 285 cam in a pinto.

Pinto Cam Advice
Good advice about priming the oil ways & spray bar, will put into practice soon I hope.
Following my post I whipped off 2 big end caps No2 & No 4 & No 1 main bearing cap, as according to Haynes its the last one in the oil supply,
and was relieved to find nice grey bearing metal on all.
Reduilding the head over the weekend & shortening sump - with luck.

Many thanks everyone for the advice. Engine is coming next week so can start head re-build soon. I think ill start with Piper270 for starters as it is
cheap. Later, as funds allow, id like to go for 2.1, better head and twin45's. unless i lay my hands on a good deal for 2.0 Zetec on throttle
bodies etc. (Minimum 2yrs before i look at this, post SVA project).
Next major decision is injection or carbs. Iam from the era where carbs were almost totally replaced by injection. Ive only had 2 carb'd cars
before so dont really know the pitfalls. Ive heard they have to be set-up v.well and have a tendancy to cause problems.
Iam favouring injection but cannot afford mappable set up and dont know enough about modding the Sierra set-up to fit - yet. Shouldnt be too hard
though - just a case of getting the correct bits right????
Cairb - you have u2u.
Thanks again and a prosperous 2005 to all,
Darren.

If you want to use the Sierra injection setup then Mark Allanson has written a really great guide to doing it.
If you want to do your own then it seems that a set of Gixxer 750 throttle bodies and Megasquirt is the way to go.
HTH,
James
