ok ive just put a new head gasket on my ef i also put a new timing chain and new timing chain tensioner
now ive put it all back together and releast the tensioner and the chain pulls tight ok

now i give it a test run and start the engine wat i hear on start up is a rattling noise and also wen i rev it to a bout 1500rpm the chain ratles it head off

can any one help me with this?

Did you have alot machined off the head ? If you take too much off it puts slack in the timing chain and causes a bit of rattle (my new engine does it a little but its had alot taken off the head and block)

My old engine did the rattling at 1500 revs thing too after doing the head, cam etc but I didn't replace the chain and I broke the top off the timing chain guide

If it's still rattling it sounds like there's not enough tension so I'd try resetting the tensioner again.

ive set the tensioner about six times and it just doesnt want to work

i first did it with the old chain last night then i put the new chain in thismorning and it still doing the noise i might try and take a link out of the chain and see wat that does


oh and i took about 20 thou of the head

NOT TO WORRY I FIXT IT

What was wrong ?
You're pretty keen taking timing chains right on and off - I CBF even fixing my broken guide because of the amount of work involved pulling everything off

BTW I suspect taking a link out of the chain would make it way too tight...

i cut the old chain off and wound the engine over with the new chain conected to the old one

and i reset the tensioner twice and its all fixted now
