Engine & Gearbox H22A7, possibly pinking?

    After giving the Accord a good run and plenty of VTEC on Saturday, I noticed a bit of a rattle from 2.5k ish and above. Can't really hear it above 5k ish as the engine just gets pretty loud naturally by then. Revving when in neutral or with the clutch in I can't notice anything.

    I immediately shat myself and assumed the worst, but Loplop reckons it sounds like pinking. I've never really heard pinking in another car so have nothing to compare it to. Sounds kinda top end ish, could it be anything in the head like a fucked cam or tappet? I assume it's not as it can't be heard unless under load.

    It's on V Power so it's not being caused by shit fuel, but would it be worth trying octane booster? As higher octane is more resistant to pre ignition, so would show if it is pinking surely?

    Not sure what oils in it as I've only just bought it but I've been topping it up with 5W40 Castrol Edge.


    Also sorry about the big block of text, I put it in paragraphs but my phones fucked it up.

    Have you tried whipping a spark plug out yet mate to see what they look like?

    What has lead me to believe it is pinking is: A. The noise. and B. The fact it only happens under load.

    It wasn't loud enough to sound 'tappety'.

    Spark plug change is definitely worth it though for piece of mind.

    Isn't really pale coloured soot on spark plugs usually a sign of pinking or lean mixture?

    I'll check all the plugs tonight, and get some new ones tomorrow for peace of mind. Was speaking to Rammy on Friday night actually, he was telling me he had a supercharged Integra which was on iridium plugs, they overheated and made it pink, and then it blew up. Then the next day I notice the noise, haha....

    Liam I reckon it's got a bit louder but I'm not sure, can still only hear it with the windows up.

    Might just bosh a set of new NGK's in tonight and see what happens.

    I reckon that's you being paranoid Jakk :Wink: You've heard lots of horror stories about H22's and you've got one with high miles so you're kind of expecting it to blow. But the engine is strong mate and the car has been looked after! Just enjoy it :Smile:

    Yeah pretty much exactly that. Haha

    Hope it's not running lean as that means it'll be even worse on fuel when fixed!

    My A7 was fucking shit lol, nothing but problems!

    Hope it's not and your engine is a strong one!

    Some plug reading for you.

    I believe silly little things like this could be problems you run into with the fact it has Full Honda SH.

    They still get apprentices there... Maybe one of them got left to change the spark plugs? Put ones for a normal Accord in?

    Full Honda service history doesn't mean much these days. Quite possible that some dealers would not know what an ATR is :Tongue:

    The garage that fitted my cambelt did not align the balance shafts correctly due to lack of knowledge, things like that happen with older/less common models unfortunately.

    If it's on the stock map and bolt ons, there is very little chance of it pinking.

    Not if it's had the wrong spark plugs put in...

    Honda issued a bulletin about the pinking when the Accord was first released,i might still have it somewhere. I'll have a look at work tomorrow.
