I managed to get the car started..... once the car started it made a really loud tapping noise, but after about 30miles it died down. when the car is on idel there is a faint tapping noise, but as soon as i accellerate off the mark and through the gears it gets louder and quicker. when the car is at 65mph the sound seems to get quieter again???? the car is running really smooth and isn't miss fireing or smoking. If thats not enough driving home from work today it just cuts out......now no spark ahhhhh!!! help me please i've been doing this rebuild for a year now and want her finished..lol.

 

would ask the obvious about timing ... only needs to be a bit out on the belt ...

 

Did you aling the bottom pulley with the right marking.

Steve

 

dont know about your misfire mate,but dont worry about the lifters they will quieten down with miles mine came and went and took ages

 

i have no miss fire on the car, just a tapping noise. yeah timed the car up exact on the lobe. before timing i downloaded the cosworth workshop manual. i timed it up on the lobe thing not the groves.

 

just get the miles on it,it will be fine

 

So presumably with No 1 at TDC, both the arrows on the cam pulleys point right at each other?

Did you replace the tappets? They will make a proper racket when they're new - get an oil and filter change done. If it's coming and going it's most likely the tappets. Mine does it - silent on startup, then gets a little tappety, then goes quiet again. Do you have an oil pressure gauge?

 

Is it louder when you put more load on the engine??

 

going to put a oil presseur gauge in the car. yeah the sound gets louder under load?

 

the tappy noise; is it top end or bottom

 

its not the lugs on your bottom pulley hitting the crank sensor is it..?

edit.. just realised you've probably got an rst, i'm thinking cossie, so dont know if its a possible or not.

 

Its a cossie m8.

Steve

 

so it is, just reread it..

i refer the gentleman to my first answer then..(done that one myself)

 

if the tapping noise sounds loud and deep/knocking, sounds like a big end.
was the crank checked/ground when engine was rebuilt??
correct undersized bearings used??

 

it was the tappets the noise has now gone. as for the car cutting out it was a fuse for the fuel pump. all is sorted and she is running like a dream, all ready for the shows.

 

glad to hear it

 

Good news m8, look forward to seeing it again

Steve

 

tappets CAN take a good few miles to fill completely after a rebuild! ALLS good then!now just get some miles on the clock!
