hi new member with pinto efi

[stefancapri]

in a capri. resentlly i did a bit of head work with a skim, you know the everyday drivable benifits, 35tho skim, fr 34 cam and a bit of diy polishing/porting.

 

however i cant seam to sort my valve seals out, so far in the last 1000 miles since the cam ive had the engine out twice to clean the sum out and replace my oil pump jue to valve seals destrying there selves, i started off with the cvh ones, thinking after a few miles it started smoking again thought it was a dodgy batch, i then replaced them again, but it was no use, i then replaced em with the kent cam slim ones, but i was told they slipped off! and 500 miles later after a good thrashing to santa pod 1 or 2 have slipped off, now i did try superglueing them, but i guess with the heat there wasnet a chance shorly somone else is using the fr34 cam what have you done? new i should of just got the fr32 cam.

welcome to the site bud

i'm sure someone on here will help you solve this problem

[bortaf]

Do you need double springs with the FR34 then?

if not i cant see how the cam affects the valve seals

i run an FR30 (nearest grind to the FR34) in my EFi with standards seals and not had a problem in 10 thou odd

Hello and welcome to OSF

Hi, welcome to OSF - hope you get it sorted

[stefancapri]

ive looked through the kent book and the fr34 cam has the most life of the fr range, the only ones that have suvived are the slim style, but as i said they slip off, normal single spring came in the kent cam kit, what do u people do with the mega high lift cams, i guess its head work?

 

thanks, there must be a way of getting round this ?

(copyed from kent website)

7.62(mm) cam lift on a fr34

I 12.67 E 12.31(mm) valve lift on a fr34

 

7.36(mm) cam lift on a fr30

I 11.93 E 11.73(mm) valve lift on a fr30

Like i said why did you use the CVH or thin seals?

just use the standard ones, cam lift has nothing to do with the seals unless you have double springs which need the thinner seals to clear the inner spring.

I run an EFi pinto as well but the FR30 came up cheap and it's more like the FR34 than any other cam they do

 

The FR34 doesn't need any head work (like the spring seat deepening) well at least according to Burtons and the cam manufacturers it doesn't, the EFi doesn't like wide duration cams the idle gets very iratic hense the high lift low(ish) duration FR34 (sports injection cam)

hi welcome to the site

[stefancapri]

i dunno why i went for cvh seals, i guess i found good reports on them, and when i did em the 3rd time it dident look like there was any difference in size between the cvh and std seals, so i used the slim ones, big mistake. might be worth a go tho, i need to do the tappets again anyway.

Welcome to OSF mate, and good luck with the seals

[kevmk2]

Welcome aboard

[bortaf]

Make sure you get a good kit some just push on you want the ones you need to punch on with a drift (or ratchet extension bar in my case)

Mine was a paynes set (sp?) done 10 thou without a problem (crosses fingers and hopes "fate" wern't listeming )

 

While you doing it check if there's play in the valve guides that will wear the seals but not had em lift off before except on high revving race jobbies, admitedly i rarely touch 6K on mine but then i'm a lazy driver hense i was happy when the FR30 "high torque" cam came up

yeh they are rev limeted by the ECU, you can get a superchip that raises the level

[stefancapri]

yeh, been looking around at the chips you can get, looks to be a few avalible for the eec iv but dont really want the limmiter to be much higher with a bog std bottem end, as could end in disastor, out of intrest any you would reccomemnd, known to work well with the efi system?

[bortaf]

Only really ever seen a superchips one (not even sure if they still make em TBH?) it's the EECIV that limets the power over about 130 ish, i'm looking into after market (Emerald, meagsquirt ect) you can set your own and from the prices of a new superchip you could build a compleat MS set up for less.

Esmie used cossie managment so that's allways one to keep in mind.

I have a plan to run an EFI pinto closed loop but no-one seems to know if i can swap an EFi chip into a twink ECU, if you could you could bin the restrictive AFM and go map/TPS, other than that it MS or emerald ect

[stefancapri]

cool, well ill keep an eye on this to see how this goes, trouble is with mega squirt, i knew somone that went for this but dont think ever got any sucess from it, not sure what i wanna do, coz ive spent way to much on the pinto for what ive gained, so if i carry on with the pinto, i need to look ferver into ecu's and stuff. ill have to deside aftermy holiday. its nice to find somone that knows there stuff about pinto efi's, coz there rare lol
