Resetting GPX tappets

Craig · Post by **Craig** » Sun Dec 21, 2003 2:53 am

Just finished resetting the Tappets in my GPX
It had done 97,000km and the tappets had never been reset, and the ticking was so loud!
After taking the rocker covers and intake trunk off, and putting a thickness gauge under the small lobe the distance between the lobe and the tappet was heaps!.. Anyways after adjusting the screws on both intake and exhaust and putting everything back togethor, changing the cam belt, and taking it easy on the engine for a few days. when i went to 5,500rpm when mivec kicks in, there was such a difference. Mivec became more noticeable, and seemed to be quicker.
AS for the tool for the lock nut, all i did was get a small 10mm socket, a small thin extension for the socket. Then with a grinder, made the 10mm socket thinner so i could get to the lock nut under the big lobe. No welding or anything like that!...
It was well worth resetting the tappets, Mivec is more noticeable and sounds better, All ticking now Gone!!!... and more horsepower...
Well it's 2.41am.. sunday morning at work... bored... so i thought i'd post this random topic...
Anyways Take care all
Craig

dude, you should videotape the whole process and burn it onto CD when you're in town next year... That way we can all learn to do it ourselves and not get ripped off by damn mechanics!

Hello Craig,

I have a problem with my tappets as well and I was looking to replace them.
And when I got the parts asking what I need to replace the lifters, they gave me 12 of these little screws with plastic bits to them. And was told that the lifters don't stay at correct settings for a long time because these plastic bits on these screws which are attached to the lifters worn out and need to be replaced.
So I got few of them and now I cannot seem to find any one who can replace them.

While you were doing your work, did you happened to see these screws on the lifters? and do you think you might be able to replace them as well? If you can please let me know as I am very much willing to pay you to do this for me or I can even help you while you are doing this and I guess it doesn't have to be during a normal working hours, I'm more than happy to work on it with you after hours.

Please let me know as my tappets are very loud and no matter how many times I get my tappets adjusted, they never stay quite for more than a few weeks, if even that.

So please let me know and maybe you could PM me about this.

Thank you very much for your time Craig.

hey
Appologies for the late reply.. just started work again after christmas break.
Screws on the lifers?
u mean the 2 screws to each of the rockers?

If it is those screws you need replacing then i'm not sure.. it could be as simple as screwing out the old ones and replacing them... but i'm not sure if that'll upset the rocker... i should have taken some pics of when me and my old man did the work... I have the full workshop manual on CD.. if u want i'll send you the Tappets part via email...

Give Malcolm Crockenberg a call in Perth
(08) 9358 0302
My old man used to work with him at ralliart so we gave him a call, and he gave us some advice, his done the tappets on FTO's quite a few times, maybe he can answer your questions.
Other then that matey i'm still learning these sorta things, so i really would be able to them knowing i'm done it correctly... and plus i'm off to melbourne then darwin for work, so i just would'nt have the time..
But if you want those pages about the tappets from the manual just let me know
Take it east
Craig

Hi would like to ask when adjusting the tappets, do u need to replace the gaskets, if so which gasket and who suppies it. Thanks

Craig · Post by **Craig** » Tue Dec 30, 2003 5:04 am

Hey
Nope theres no gaskets to replace...
When taking the air intake truck off to get to the rear head just take it slow and you'll find that the gasket from the intake trunk to the head should be fine, if it does happen to be sh*t then i suppose get one from any mitsubishi dealer?..
my gasket was fine so i did'nt replace it...

do you adjust the high speed an low speed lobes? or only the low speed like the illustration in the manual?

Dude, turn the page....

Got caught with that myself. However, my tappets did not stay quiet for very long. Still, major service coming up soon, so hopefully get fixed properly then.

So if i was to get my mechanic to do it, what should he be looking for? Im in desperate need to get mine done!

ruchi · Post by **ruchi** » Sun Sep 26, 2004 6:40 pm

I suggest quite strongly you take it to a mechanic who already knows how to do this.

I don't think it's that hard... all your doing is making adjustments, using feeler gauges to re-adjust the distances... any sensible mechanic should be able to do it... or am i incorrect in the procedure?

It is a little more complicated as you really need to have seen it before otherwise it will be a waste of time. If you dont have the correct tool (either official tool or a manufactured one) it can be a really big pain and very time consuming.

OMG that is an awesome idea, make a whole lot of videos of diy jobs on the fto, from simples ones like changing the oil, to tappets, and even odifications. downloadable on the internet !! I have access to a digital video camera and a few video editing macs, I might think about making a few with my mechanic

I had a chat to my mechanic the other day, and he wanted to know if the tappets are a "bucket and Shim' type or a "Screw" type. Can anyone shed light on this? What does the gap need to be?

Boris · Post by **Boris** » Mon Oct 04, 2004 12:04 am

Umm question... one mechanic that I asked said that the Mivec ones are hydrolic... so he can't adjust them.... someone please explain, or is this dude incorrect?

The MIVEC engine tappets are definately adjustable, the GR engine tappets are hydraulic.

LOL!

Let me re-iterate my first statement again.... (the mechanic is incorrect)

If you're going to get this done, get it done properly. Over and over and over again we hear of mechanics who reckon they can do this and then don't have a clue what to do and who get confused between the automatically adjusting hydraulic lifters and the manually adjustable tappets.

Don't pay for someone who doesn't know what they are doing or who has to learn on the job, take it to someone who actually knows what a FTO is and who has the proper tools and who can do it properly.

yeah i agree with Ruchi *OMG i cant believe i just said that*

i wouldnt just give it to any mechanic, it has to be someone that has done it be4 and knows what they are doing.
