hi all,
i havn't investigated yet but just bought an xr2i for the stage 3 cvh thats in it for my rally car. well, from cold she starts spot on. straight away truns over fast and doesn't tap from cold. if i have done a long run and stop for more than half hour so it cools down it starts great the same. but if i stop it and try to start it again straight away when its hot it wont run!! it will not start, turns over like theirs no battery and doesnt want to know. now the weird bit, if i bump start it say just after it stopped to get it going it will tap like hell! for a few minutes! then it quietens, no idea where the tapping is coming from and whats causing it. can anyone shed any light?

dont know if its the same for n/a cvh but my series2 turbo did this because the hot turbo was cooking the starter motor,thats all the idea i can suggest.

thats good news, because it has a 4 branch manifold that is bloody close to the starter motor which was my initial thought. that would explain not starting but would it explain the tapping? did yours tap and how did you solve it?

Same with me the manifold etc was heating up the starter, mint from cold but as soon as you'd been on a run it wouldnt start and had to wait 10-15 mins for it to turn over, right nightmare when stopping for petrol.

I'm sure I put bigger starter on - heat wrap is good a good idea as well though

xr3irally

that was my first thought but it doesnt explain the tapping?? ny suggestioins, were your cars tapping when you bump started them when hot also?

steveyb

my starter has started doin this now, can you still get o.e. heat shields for the s2?

as for the tapping maybe the oil has drained just enough to tap the top end as when you start off the starter the pump has had a second or 2 to get oil up? just a thought?

kosman

mine never tapped but i did always leave it till it went cold again,mainly because i never used it so cant answer that me man,and yeah geta good heatshield for your car and it should be ok.

xr3irally

i am pretty sure its the heat thats making it not start its just the tapping thats worrying me. fair enough if it tapped for a few seconds i would put it down to the lifters losing pressure but it taps for literally 2mins!! that cant be right? when i start it cold in the morning it starts first turn of the motor and doesn't tap at all which is what most cvh's do when they lose pressure in the lifters. thats what makes me thing it isnt that.... how annoying!!!!! especially as its a donor engine for the rally car i dont want it failing on stage

Has the starter motor got a push on connecter or a "O" ring and nut? The push version expands with heat and even though it looks like it is ok the connection is not good. Ford did a conversion kit.

xr3irally

i didnt know that, and yes it does have a push on. i can see the logic there. i will get it converted this weekend. still doesn't explain the tap tap tap tapping i get though!!

xr3irally

anyone got a theory for the tapping?lol

xr3irally

last bump....

kosman

how bad is your tapping? think you'd be best ringing a expert off here tbh,do cams tap? you could have a sticking tappet,common on cvh's

Try locate where the tapping is coming from since you say it taps for 2 minutes or so more than enough time to poke your head around and try narrow down a location.

xr3irally

it sounds exactly like tappets, thing is it doens't do it from cold whihc tappets usually do. and they would lose more pressure overnight than they would in the short time the car is stopped between runs. weird. i cant see the starter tapping as it wouldn't have move with a bump start unless it isn't disengaging properly? or my attempts at turning it slowly on the key are doing something. i dont know. will swap it into the rally car at the weekend and see if it likes it better in there!

i had same problem and it was due to the oil bein hot and draining out the tappetts a flush and som new oil it was loads better HTH mate

My seriers 2 used to do exactly the same thing.

It also did the tapping, it would only do it after trying to start it loads of times when its hot, when i came to bumping it, it wouold then tap. But say if it was still hot, but i hadnt tryed to start it normally and bumped it straight away, it wouldnt tap. So id say its some thing to do with that your trying to start it so many times?

I bought a new starter motor, a new heat shield for it from ford, and heat wrapped part of the exhaust and never had probloems again.

xr3irally

good good, at least im not the only one.lol, i think im gonna try and make up a heatshield this weekend when its out. and yes i tuend it over loads slowly before i bumped it and it tapped. hopefully it wont be an issue when its sorted and starts on the key. thanks for all the help!!
