Hydraulic Lifters for 4G93T

[tonytony]

lol, like i said, sumtimes i just go whacky..

here is the long elaborated story of how my lifters came back to lives and haunt me, lol

after adding the extra washer, it was all okie.. den, i found out dat joshua eliminated the ticking diesel noise in a modified hilux turbo diesel by using a mono50 weight oil. dat diesel was running smoothly witout the well known clatter of any diesel engine.

after sum time, i cam to a shop and accidentally saw a mono40 weight oil, and the crazy light bulb in my head lit up, lol. just to try maa, u know? if a mono50 is able to quiet down a diesel, den a mono40 weight oil shud be able to help a petrol, at least in my case to keep the noise suppressed down. during dis time, i found out dat my fc got better, but 2 days after i poured 200ml into the crank, i notices a slight noise dat is very well known, a slight only.. den, worrying dat the noise wud get worse, i decided to try a well known oil additive (again, wit the crazy bulb..), the bardahl-1 and the slight, slight noise again disappear for a couple of days.

today, the noise isnt apparent, but as i said the fc got better and iam still on my last fuel fill, 20hengget since last tuesday, it has been around 200km since den

ic ic ic, bro....this is from my experience. just use regular semi-syn (if ur engine din makan minyak). i say this because after i've done my washer thing, lifter noise was on a gradual improving trend. what i mean is lifter noise reduced from week to week and oil change to oil change. by reduced i mean after week 1, lifter was already working like new with no tik tik tik.....and the situation has been improved by so much that now i complain about my K&N breathing sound while idling !! with old engine, i din expect my lifter/HLA to operate like new, so i only get the tik tik noise when cold start in the morning, but that also for the first few revolutions on the engine (that is only at max 1 second). once oil is pumped up to engine head, no lifter/HLA noise at all. therefore, no need to experiment with different different oils any more bro....

hope this info helps.

up the thread..
dear all,
despite adding washer to the relief valve spring, can we just change the spring with higher pressure?

I don't recommend that. Cause:-

1) u don't know what spring ratevu're running now.
2) u don't know how much difference u're adding into it.

Explaination:-

when u're adding 1-3 washers, u'll roughly know that the difference is not so much. But good enough to make the difference. What if u've over tensioned the relief valve with over rate spring? U'll have too much oil on the cylinders head and too less oil in the pan/block. So, ur crank and other moving parts may suffer from oil starvation and too little lubrication. This could damage the following items:-

1) conrod bearing
2) main bearing
3) thrust bearing
4) cylinder wall + pistons(no oil)
5) crank(worse case scenario)

Hi Tony, thanks for the concern. I gave up trying on oils. And I've ordered the aussie's lifters. Still haven't get it installed cause working 6 days a week and 12 hours a day. Will update the thread once I have them installed.

Well I was even more convinced when a friend of mine tht's using it told me that his putra's engine oil sump was left open for 1 month + and had all the oils in the engine drained out completely. When
got everything installed back and had the engine started, not even a single ticking sound was heard.

Now waiting to get the lifters installed into my engine. Feeling is like waiting for wife to enter the room on the first day of marriage... Hahaha...

 

[xtremeleo]

speed, can u get a pix on those lifters up? i wanna see ler, is the hole made bigger? much bigger ker?

 

[speed2horizon]

When I dismentle the old lifters, the I'll take the picture compaRing those lifters.

 

[xtremeleo]

thanx in advance sir

 

[tonytony]

wow, good project on the way. yes, pls update us on ur progress. how much did the new lifters costs you ?

is this normal for mitsu engine owners to order new lifters from aussie-land? for mazdas, heard of some doing it, the HLAs were much cheaper in AUD or NZ as well

Thanks man..

Just a guide for Kenny,

Oil Pressure readings for the 4G93 without oil cooler
Idle (Hot) - 1 -1.5bar
Normal driving - 3.5 - 4.5bar
Boosting - 5 - 6bar

I'm using all sorts of engine oils but my peak oil pressure during boost is at 4bar only. Any concerns for this ah? with oil cooler that is... normal driving 3bar only. but so far my engine bearings still in good condition after 2 track days... already added washer to the oil pump spring. anyone can donate their 4g9x oil pump for me to test it out?

Gave up on tappet noise... if you can't beat them join them...

Look for mivec pump. They have higher pressure.

s2h, your australian lifters fix already ka? let us know if the bitch still tick or not.
MYR800 for all 16pcs man....

 

[AlucarD]

Ftzone, I had the lifters installed on my evo and running super silent now. Can even hear my timing belt sound... damn noizy.... huhuhuhuh... :P
