Engine tapping! Help!

[Shwdii Beii]

Recently noticed the engine is very loud, it's got a continuous tap which goes with the revs, it sounds like it's from the top end, no loss if power or anything like that just very noisy and tappy. I started up mt other Glanza and this one was quiet as anything!!

Any ideas would be appreciated!

Thanks Sion

is it just when you rev it ? and when the revs drop is there anoise ?

Mine does the same and so did my sr when i had it. Like a faint knocking top end. Never got any worse on my sr or glanza

Unplug your icv pretty sure it's that making the noise

Could be worn shims in the head. Re-shimming would solve it. I gathered tonnes of shimes from scrapyard and did mine on my engine rebuild. Not a hard or expensive job to do just time cosuming. worth it though when you fire it up and it's nice and quiet can just hear the injectors ticking on mine now no tapping

It's tappy throughout the rev range just doesn't sound nice atall ): I started my other forged V up and it's silent in comparison! Been working flat out so ain't had the chance to have a proper look! Might be down to shims like you said!

Thanks for all the response! Appreciate it. Will let you know once solved (:

Oops posted twice! I read up about that inlet cam tensioner and thought it could be! Just need to have a proper look!

Thanks again for all the help.

there is a big circlips holding the front (scinny cog ) on when thats removed you can see the monster big clip inside check the cups on it and the pin holding it in !!!

[Shwdii Beii]

Re-tensioned the inlet cam, unplugged icv and still the same ): might have to be a session of re-shimming!

Any other ideas I could try before doing this?

Cheers!

Exhaust gasket , sounds like a bag of scanners x

I would be inclined to believe that the cams need re-shimming. Funnily enough had the same diagnosis on mine just last night!

if it needs rechimming then you could use some shims in difernt places just nead to measure right

when i did my head then i managed to swap them around and only needed 6 out of 16 new shims ( they are 10 a pop )

In for reshimming tomorrow (: I had a spare 4e engine sitting at home so just gonna use the shims outs of that saves me a little money (: hopefully be quiet as anything then ha

Been looking to see what they should be at, found this from tgtt that a member posted -

4E-FTE Valve clearance with the engine cold are:

Intake 0.17mm - 0.23mm

Exhaust 0.27mm - 0.33mm

Any one have an idea? Seen you've posted on my other thread Colin, I could only find a manual for a 5e paseo :s

Thanks (:
