Engine tick

[wrxboy]

I noticed today when i popped my bonnet that my engine makes a ticking noise and with more revs it gets faster but with more revs it goes away?? it not piston slap as its not that sort of noise??

Any ideas thanks

what year is your car? does it still have the engine and heads it came with from factory.

my bet is you have early < v2 heads and the heads are ticking. When was the last time you gave it a service?

[wrxboy]

A 1997 jdm wrx yup all engine standerd apart from extractors and exhaust and bov!!! service was 1000km ago??? do you think somethings wrong??

[Guest]

just be the heads ticking man.

[wrxboy]

so nothing to wori about??

[G-unit]

ive never herd a gc8/gf8 engine that doesnt tick/make a weird noise, they do seem like noisy engines the ej20

[DRFVDR]

its not a fault its a Feature

or how Mister Jobs would say " you are holding it wrong " :)

seriously it fine

u can try overfilling the oil by 1/2 a litre see if that quiets it

[Guest S T E Y E]

hmm sure its not just ur injectors ticking?

when the coil inside the injector is energised then colapses to open the pintle inside the injector it makes a tick so basicly everytime it injects fuel it ticks...

also WRX doesnt have tappets (hydraulic lifters) ...(RS legacys do)...my old v2 wrx had a ticking sound and it turned out to be tarnish on the cam buckets (wrxs have bucket over shim) and the tarnish (sorta like burnt oil on it) makes a ticking sound...sometimes engine flush and new oil can make this go away if its bothering u but if its built up quite bad it wont go away haha...

its nothing to worry about tho its not gona blow ya engine....

either its tarnish or the bucket over shim is out of adjustment...(worn down and loose) sorta like in the old days when u have adjustable tappits and theyre out of adjustment and loose....

V1 and V2 wrx have hydraulic lifters and these will stick and cause a tapping noise.

V3 and v4 sti have buckets over shims.

As stated most ej20 engines make some sort of odd noises and every car seems to have its own noise,i call it character and you will learn to live with it.Although it can be a bit disconcerting and can lead to mild mechanical paranoia at times.

[Guest S T E Y E]

really??? the v1 and 2 have hydraulic lifters?? i thort they only came out in rs and gt legacys??

that sux haha im glad i dont have my old V2 engine anymore haha

the noise is probly the fact that the tiny ports in the hydraulic lifter are blocked with gunge and oil sludge etc...run a engine flush through it and add new oil with lifterkleen and the noise should minimize but will probly still be there but not as loud...

but like i said most people think noisy lifters are the injector pulses...injectors are pretty loud ticking

[Guest S T E Y E]

heres some info i got off another forum

Im sure the STi Version 1 ~ 2 and WRX were Hydraulic - the STi having lightweight Hydraulic lifters.

STi Version 2 RA had solid lifters ( top hat inner shims ).

STi Version 3 ~ 4 were as you said, solid lifters.

Some Version 3 ~ 4 V-Limited and Type R had either small outer shims or the regular STi Inner shims

my v3 sti tickss too, I was toldto run some cleaner through it, and use thicker oil due to the age of my car

[Swindog]

exhaust leak somewhere can give a funny sound sometimes.

[Guest S T E Y E]

thicker oil??? who told u that?? thicker oil makes the tick worse bro as the thick oil cant get into the hydraulic lifter or wherever it needs to go...

u use a thick oil for a worn engine with worn bigend bearings etc with huge tolerances...thin oil for tight tolerances

As its a V3 STI it will have solid lifters. So the theory is to stop solid lifters ticking, use a thicker oil to "soften the impact" from the cams on the buckets that have larger clearances cause they're old. Thinner oil will make it worse in the case of solid lifters.

Yer, thats what I've been told on here and what the old guy at Repco said as my car is on 186k

However, he sold me some Penrite SPR 10w50 stuff as I've always used Shell Helix Ultra 5w40, and now i've got buyers remorse. Anyone know if its any good?

[Swindog]

Id be running castrol gtx 15w40 to be honest but im biased castrol.

[Guest S T E Y E]

that gtx oil is crap as tho...

would a 10w40 be good in my sti motor?

[Swindog]

I run it in my old motor which was a speed monster fully forged etc and was ideal. Never ever had a problem.
