Valves............how do your exhaust ones look?

They are usually pitted.

You can still by new aftermarket ones that are inexpensive, did this on the AC just to be sure.

none of the valves are pitted.
I'll try getting better pictures.
This is of the AC model ,it has oil cooler and im only guessing it has less kms done
as its been in storage for over 10 years.
im going to be Porting & Polishing head ,all i have is time.
stay tuned

here is better pic of valves
the exhaust valves are still dirty im going to sand them back
with fine sand paper should look like new
head been cleaned

i have cleaned valves there is still some black stain but can't feel metal edge been pitted
the picture goes all blurry pointles

They look pretty clean, if you run them over a wire wheel they will look new.

i have but my wire brush is very soft so i used 800p wet and dry rub back were the valve sits
looks ok now i'll be porting and polish the head just the exhaust and inlet chambers
been waiting long time for new valve stem seals hope comes this week
them i'll be checking compression ,if compression is bad i'll be doing piston rings and bearings.
lets hope not

Just hope your Pistons don't look like mine. Safe to say it shocked me.




Do you have a build thread that I havnt discovered? I wanna see what this beast looks like

top pistons was bad carbon was like 5mm thick.
valves were covered staying open.
so i don't wont to remove piston don't see the point.
cylinder walls are clean no sign of bad pistons.
my older engine i might built it up later on in case
i blow this one up for over boosting

Hi Fernando,

Sorry you are having so much trouble getting the car going. I would never of thought the engine would of had so much carbon build up. For those that wouldn't know this was my old engine. Oil was changed with mobil 1 every 5000km's then when that got to expensive i changed to gtx3 every 5000km's. I would be very surprised and sad to hear if there is any damage to the pistons or bores. It did run smooth as a whistle until it decided to not boost anymore. would start off in 20 vacuum , accelerated to 0 , then would not go into boost pressure.

For all i could of known it may of just been a vacuum line split or missing. maybe it was all that carbon doing something. I never opened it up to find out. I just bought a vr4 front cut instead and went vr4. This was all in 1999 mind you so that engine has sat under cover for probably 17 years. If after this fixing up by Fernando it works then I will be very excited and happy for him and would love to know what the problem is / was.

Good luck with it,

Brad

Hi Brad welcome back.
To me is all a learning experience.
I really don't know anything about engines.
I can replace & remove engine parts
But the function is another story .
About the boosting on this engine
Only Andrew can answer your question .
I have read one of the post here, guy says if your engine has very low
Compression the turbo will not boost !
Also just cause engine has fuel pump doesn't mean fuel is going in to throttle body.
It needs compression so I have learn quite a lot .
After I did compression test found out no compression at all dry or wet.
My son said the way engine turns so easy means also rings are stuffed pretty
much as f... Up as my AB one.
My son shook his head told me stop wasting my time lol.
I don't give my baby up that easy lol
its giving me something to keep busy and a purpose in life
my biggest problem is finding cheap parts .
the more i dig into the engine the more it costs.
i have spent over 2k on this car.
its not even registed yet
engine still stuffed some times i feel like getting a strong rope

Stay strong mate. I have spent about 3k so far and I'm far from
Complete

yeah just common sense says we are never going to get our money back.
regardless how wonderful we get the car.
i suppose 5k is not so bad to keep someone sain in head.
i think that's what will cost me in the end.
i need to get me job before i go nuts

update on fuel cut thingy.
http://www.jaycar.com.au/Kits,-Science- ... e/p/KC5439

they don't make them any more

That's a shame
Also yeah 5k isn't too bad for something that keeps you happy
Mine will cost a little more and that's just to get it in a nice, stock look with a standard 4g63t

update:

my new seals have arrived
time to put head together and test compression.

i tried buying these in Autoone .
that's where i normally buy my parts from specially paint.
i must admit haven't bought car parts probably 10 years.
i know the fellas that work there they always give trade discount
on paint .i asked for seals they said most suppliers have closed
is not worth it for them ring Adelaide or Queensland etc
to find they will charge double the amount of money.
best for me to buy online.

It's getting exciting! Are you getting you head checked at a shop? Or bolting back on and compression test?

no need to have head checked ,was never blown gasket
its not warp .
i had a look on YouTube about checking head .
use ruler and Feeler Gauge is all good.
i'll be using my old gasket as nothing wrong with it.
just to check compression hopefully has good compression
if not i'll need new rings done, possibly new oversize pistons
this way i don't waste my new gasket.
im just gona cross my fingers some times a bit of luck goes long
way

Andrew hope your faraway from storm look after your self.

i spoke to person on ebay selling fuel cut defender
the 3 wire box,he said there's no need to cut yellow wire.
he gave me picture of installation.
let me know what you think before i make big mistake buying it.

Good work.
