And other junk I don't like to talk about!
you will need to drill a small hole in the block on the crossflow engine to feed a little more oil to the cam dizzy / oil pump drive to prevent wearing of drive on cam which causes lots of lash in your dizzy eratic timing
Sorry I missed much of the last replies,
RWD I can see the lip.
Trust me I've done 4 pumps like this (Ford pumps) and just about everone that I know that races pinto's here does it.
Turn the cap down or mill up a thinner one to sit in , thus stiing further down the body.
Could well be,
I just did a pump for my motor last week, I have a spare that has some bad wear on it, I might just cut it open and have a look inside.
Hi mates, it's me again, now with a query about oil pressure on my 2 ltr Pinto engine. Despite I'm going to do to my std oil pump all what RWD ford rules described, thank you, I have experienced today this situation:
I started up the engine with the std pump and I obtained 45 psi at 2000 rpm and 80º C., which is correct. Now I changed the oil pump for a hi pressure one - Kent manufactured - and my new pump gave me 45 psi at idle and 80 psi + at 2000 rpm, temp always 80º C. Isn't that too much ?
I'm worried about what will happen when my engine will be at 6000 - 7000 rpm.
Can anybody give me a little of his expertness about this matter ?
Wait your kind advices.
Cheers,
Eduardo

i'd see if the pressure goes higher still with more revs it may not, if it doesnt dont worry
Sounds like you fitted a high volume high pressure pump? some of the pumps have very strong pressure relief valve springs, if the oil pressure goes over 100psi cold it will have to be looked at, don't worry about 95 to 100psi max cold with thick 20w50 oil it won't hurt the engine, you only need about 60psi hot oil pressure for any pinto engine, race, rally, drag, turbo whatever

Ok Graham, thanks for your kind reply. I assume then that 80 psi is Okay, isn't it ?
yes i'd say 80's ok, i'd be starting to worry at over 100
Thanks you too RWD ford rules for your kind advice. The pump I purchased is marked as high pressured only, not high volume also; I purchased it to Rally Design and they offer both types, and for the price I paid it should be high pressure only. About oil, I'm using full synthetic 5W40, so that's why I'm surprised about the high figures I'm obtaining in the manometer. By the way, the std oil pump I took away from the engine, is going to be fully transformed according to your tutorial at the beginning of this thread, thank you.

It looks like the end cap to hold in the spring, the other one looks like an oil pump to block locating dowel on the right

Yep.
The Mellings M68CHV seems the right one for our pinto,s ! Am i right ?
Ported as instructed rotor height to the pump body clearanced to .001 end plate surfaced and 3.2 mm shim under the spring. Should sealer be used under the pump end plate on reassembly?
NO defiantly no sealer
Do you mean the Melling M86B? Still available at Rockauto, bought two some month ago .

The big pump with double bearing, larger rotors is not Melling M86b. The left on, small rotor is. I also use Malling M86b and is the same size as the standard Ford pump but cast iron. It better as standard but the on on the right should be perfect, large rotors end double bearings
Oh right, you're absolutely right, you can actually see an HV pump in Roger Miller's picture. Did an M86BHV ever actually exist?
I always use M87HV on my Cologne V6 engines, the pumps are very similar to the HV pump in the picture, larger rotor then stock and double bearing. Highly recommended for the early Cologne V6 in my opinion.
