Rm8k Wira & Jazz GK5 ownership experience-A long way to go

[KHNG940413]

Wira update is quite long since the last update.

Few month back then I had adjust the tappet but after using few month later the sound coming back.
While cold start the tak tak tak sound is very loud. After the engine is warm the sound is much more less.
On 1st & 2nd gear the tak tak tak sound is like machine gun. Although it didn't affect the driving except the sound was like engine swap.Alot ppl keep asking me is my car engine swap? I was like no lah juz a standart 4g15 only lahhhh.

And another thing I found out is after adjust tappet while driving on 1 & 2 gear and then slow down while traffic or corner need to stop the exhaust didn't have any pop & bang sound. AFter the tappet sound come back and the car is like pop & bang on 1 & 2 gear while slow down(i think is due to unburn fuel something like that lah.

Bring to another shop and explain to them,they suggested me adjust 1 more time. If the sound come back agn might be the rocker arm or the camshaft have makan. He say might be the rocker arm edge which pushing the valve & valve spring there makan.

Any sifu face makan rocker arm before?

the 2nd shop is correct. Considering the age of the car, type of oil used (I don't know what you used), how the car was maintained, etc - it's possible it's worn out. Which part worn out needs visual inspection.

Did you do the re-adjustment again?

Haven't re adjust yet. The oil I using is castrol 10-40
The rocker arm if really worn out juz chg the worm out one no need to chg 12 of them right?

If you need to change, better change all.
Alternately, if planning to dispose of this engine soon, then change minimal amount also can.

Okay...saw a shop selling new rocker arm Rm22 each. If 12 is like Rm260+ haven't include installation. Wow,that is some pain in the wallet. Hahahahahhaa

Before buying, it's best to confirm they are worn. So far, these are mere speculations

Will inspect more to confirm is rocker arm worn out only I buy. Now driving is ok lah,juz quite noise & fuel consumption is a little down compare to after adjust tappet one.

If its worn out, even after adjustment the taktak sound should still be there right? If after adjustment the sound gone, then after short time it came back again, possible its because the mechanic didnt tighten it to specifications

Worn rocker not just have gap. There may be alignment issues. Wear not just limited to both contact surfaces. There's also a bush where it sits onto the shaft

Don't Forget to Inspect the Rocker Arm

Inspecting the rocker arm prevents premature valve guide wear and valve leakage.

Okay....what I mean is the between rocker & the valve have a thing that push the valve one. Forgot the name.
When we open up the head cover you can push the rocker arm to valve. The middle thingy gone.

That silver round part is the actual valve itself. See the cross section diagram below

I have never seen valve tips worn like that. Imo, the rocker should also be battered. Were incorrect valve springs used?

wow. this one is due to over-tighten with low clearance on the tappet/lifters. layman terms, tappet ikat ketat sangat. hence your valve tip makan like that.

RM800 top overhaul with 4 valves only is a bit expensive. can get top overhaul with full set of valve and seal with top gasket replacement actually. but maybe that's the standard charge there? my 93 single cam last time (2016) kena RM1.5k for top overhaul, including head skim, oversize valves, porting at valve pocket, new top gasket set, new piston rings and conrod bearings. and the workshop also changed my trailing arm bushes coz it was in the car when i sent it.

Never overhaul a car before so didn't know the market price. The boss say he will skim the head also. Wait for monday they open up all the head component 1st.
