My 205 blocked saph has what i believe to be piston slap on start up but also once warm it sound like a cam knock but it only makes this noise under load. its definately not the bottom end ie big ends but my concern is that i thought a cam would make a noise all the time and not just under load. any other ideas as to what the noise could be as i cannot buy the bits to fix it unless im sure what the problem is.
thanks

Hydraulic followers, quite normal and classic noise, usually towards the rear of the head.

Had a good listen tonight and there is knocking on idle that sounds like its coming from the rear of the head. 16 new followers it is first then. wheres the best place to purchase them as ive seen some on ebay but would assume them to be of inferior quality.

 

I bought mine from Matt Lewis and they are the genuine INA ones worth a try.

 

check your oil pressure !!!!!!!!!

 

i have the same trouble.....changed the lifters,cleaned out oil galleries..oil pressure is fine,timing is spot on,car runs perfectly..i'm lost!!!

anyone??

cheers

hi guys... i had a knocking noise when i start & cold.. from my sapp cossie... can any tell what came from..? thankss i leave it 2mins & still knocking...

 

i have the same prob noisie when cold quietens down but theres still a slight noise you give it a rev noise gos then comes back on idel

 

2WD's did suffer from "Piston slap", this was cured on the 4x4 by centraling the gudgeon pin.

If it's not that the lifters can play up as well, to be honest they are far from refined engines, only concern is if there is suspicion it's something like little/big end bearings, although the lifters can be annoying as well.

HI GUYS.. i go to garage & check again.. about the noise when i start..
i turn off the engine.. & crank with my hand 90deg`.. the engine loosing the timing.. the arrows of cams it not facing together.. the crank pulley is ok but the dizzy pulley is not good like`the cams.. i dont know why loose the setting.... i have a belt & tensionar NEWW.. & everything tight.. & last sunday i came from a ride & put it in the garage OK.. after 6 days i start it today & big noise come for mee..

 

Then don't even think about starting it!

If the timing is wrong you will cause serious engine damage!

The two cam pulleys arrows should face each other and the auxillary pulley (Dizzy) has a scribe the pulley should line up to as well, alternativly the rotor arm should face the 2 o clock position iirc, crank pulley has a notch it should line up with.

You need to be absolutely sure all this is correct before you even attempt to crank it, the noise could may well of been a valve or 2 getting struck

All you can do is time it up and see how it goes...

HI martysmartie... Thanks for respond me..

I go & time the engine again.. with all arrows/etc correctly..
i start it again & work succesfull without knocking noise..
i have the valve pockets in my pistons..

But i dont know why it lose the timing.. last sunday i park it in the garage in good niose & no knockings. my first start is yesterday & start with lose timing..

I use a Graham Goode belt.. & i always found a little bits of rubber with my pulleys cam after a ride & few very rare with the pulley dizzy... & i dont know if has, with the crank pulley , cause i can`t see it..

Thanks soo muchh
