Ive found out that my poorly xr2i has had Escort RS turbo lifters fitted (the old xr2i ones had failed and he had these spare?) are they the same for both cars? dont want to change them unless there incompatible???

They are the same mate but if they have been fitted to a head with a worn cam then the cam will have trashed them within 5 mins of the engine been started and they will be in need of replacement along with a new cam.

You say your car is poorly could you tell me the symptoms or whats wrong and i will try to help you the best i can.

so basically every sensor has been replaced for known good ones, the ecu has been repaced, all electrical connections have been cleaned, the head removed & checked, the compression is now equal in all cylinders and the diagnostic device shows no faults....which is nice

yet the problem is still there...exactly the same as always...i suppose the next thing is the Cam...i cant think of anything else???? very odd

btw - the bloke before me did fit worn lifters to a worn cam from different engines...needless to say its now very tappy

oh and also the cars struggling to pull 25 to the gallon with easy driving

DOO

there are diffrent tappets for EFI to MFI

mfi tappets finis 6129778 £11.66 each +vat
efi tappets finis 6784946 £13.53 each + vat

wildy

oh...also replaced the injectors and all the service items...

wildy

ah, so the tappets are different, i wonder if the amount they lift is different of just the fact the RS ones are Anti-pump?

DOO

Prob look the same but the EFI ones are diffrent some how??

RS ones are the same as any other cvh 1.1 1.3 1.4 1.6

I've always wondered what changed in the lifters in 1990. I should propably dismantle two side by side to find out.

wildy

would be interesting to know, probably isnt why i ve gto the problem, might pop down the scrappy at the weekend and compare the two

wildy

well...i went to that scrappy today and extracted a Htydraulic lifter from a G reg XR2I, so i could compare it to the RS ones that are in mine, and interestly they are quite different, the O/D of the body is the same , however the overall length is different, the RS lifters being approx 1mm longer. ocbviously this also throws out the oil gallery, hopefully this is the root of all the problems....a cam kit is on its way

thanks again for all ya help

Rick

if u using shand lifters, make sure u use the cam they came with

wildy

defo,,,im going to get the complete kit...so all should be cool

Rick

CVH cams wear a lot, so make sure it's ok. You can get a new set of followers with new cam for under 100 if u shop around.

wildy

just got a quoye fron my local motorfactors for 78quid for the set!! pretty good!!!

Ryan

thank god

JesseT

So is the base circle of the EFI cam then larger?

wildy

i think ryans almost had as much as he can take from my xr as i have

cheers for ya help though geeza

wildy

just a quick post to say thnks to everyone for there help!!! the problem has finally been resolved it was in-fact a seriously worn cam & followers, looking at the cam it was amazing the engine ran at all, in particualar two of the lobes had near on dis-appeared.

and cheers to ryan who fitted the cam for me!!! cheers mate
