Hey guys,

 

I have made this thread to try and find anyone in Gold Coast/Brissy/North NSW who would be able to help me with getting my 4G rebuilt, its blowing quite a bit of blue smoke, compression is down on cyl 3 (175/170/145/175) and it almost feels to be struggling for power more then usual.  I have contacted a few mechanics but no ones REALLY deals with these engines, and I would prefer to have someone familiar with these engines doing the work. Im happy to pre purchase all parts needed or do anything I can to help, I just don't have the know how or the area to have a crack at it myself.

 

My best contact is PM on here or txt/call me on 0415725337.

 

Cheers, Mike

Hi Mike, I'm building mine myself for the same reasons, nobody up here knows enough about the 4gs, enquiries are met with blank stares.
The most important work (expensive) is the machining, crack testing etc. the rest is just big boy lego. I've used Jack Bros. in slacks creek, Brisbane if that's any use to you, they have done a few machining jobs for 4gs and seemed to know about them as well as being straight forward and honest. They do a lot of high power engines for drags down there too, saw a few 502 mopar blocks when chatting to them.

Prepare for around $1500 or so for a torque hone, line hone, crack test, balance etc etc, and about 3-4 weeks or so, then parts. Will you be building standard or putting some goodies in?

Apologies if this is not much help.

Hey, I was looking to do a mostly standard rebuild with some performance parts eg springs and retainers/272 cams/3mm lifters and some other easy stuff. Don't want anything crazy out of it.

There a guy in Springwood that knows 63's.

I cant think of his name but I think he is in Timms Court.

Buy the vizard book on engine blueprinting (ebay)
And some tools. Then you will know what cylinder size bore you need. So what size pistons to buy.
Plastigauge the crank and chuck some gaskets in.
Tip some kero in the ports while head is off to check if you need valves relapped. Neaten them all up and bang it back together.
The vizard book is really good. Talks about chebbys and mopars a bit but they all have pistons.
If you can pull engine and supply the short to the machineshop, you will save plenty.

I wish I knew enough to be able to do this! Also I don't have the space/engine crane otherwise i would give it a go and save some money.

An engine import yard in Brissy has a 4G63T from a SSG with the top mount and bolt ons still attached, he only wants $1100 for it however doesn't know the condition/compression/how many kms its done. Dont want to buy it and have to have it rebuilt anyway.

Couple a battery up and put that new compression tester to work.
Dry test then wet test.

[Hyper_Mike]

So I just took it down to a mechanic i have used before and speak very highly of (Ultimate Performance Nerang) and he seems to think it may be as simple as the turbo leaking, while the low compression is a bit concerning he doesn't believe its what is causing the smoke? Any one on here have any idea if this could be causing it?

Go get a leak down test, if it turns out to be your valve stem seals then just leave it.... it's not going to hurt your engine, you will just go through oil every month.... like most cars

 

Also if you want to diagnose a faulty turbo seal, pull the exhaust manifold off and check for oil  to eliminate the oil leaking from the engine. Confirm by checking if there's oil in the dump pipe. GL mate

Like I said on other thread.
Compression test dry then wet. That will tell you how bad the rings are.
Then a leakdown test if you want. But compression test first.

Was just chatting to the cummins mechanic here (one of the cranes has a bit of blowby) he was talking about a stuffed turbo causing blowby. I asked how and he said if the turbo is sloppy the exhaust will flow past the seals and into the crankcase. So turbo is a possibility.

Personally I think it is a bad valve sealing and stuffed stem seals. Thats my one stubby bet.
But you need the tests....

If it's any help I'll be down in Brissy picking up some goodies in a couple of weeks and if you are going down the rebuild route and need to pull out the engine and box I'm more than happy to buzz down the coast and give you a hand with it while I'm floating about. I've had plenty of practice over the years.

 

Nikko for marking.........$3

 

Bags for putting nuts and bolt's in..........$2

 

Skinning your knuckles on every friggin thing in the engine bay.........priceless

 

↑↑That never gets old

 

Anyway, the offer is there for you, let me know if you need a hand Mike

[jack be nimble]

Gloves for knuckles...

[brisvr4]

Gloves. Pfft.. Gloves are for wusses! Losing a little skin never hurt anyone!

[jack be nimble]

Yea, back in your day they used to put children in coal mines too.:-)

I have soft hands and cry easy. Gloves please.

HAHA, yeah I'm over the skinned knuckles, the worst is the jagged hard baked ziptie ends that have your wrists looking like a cry for help. I might wuss out and grab a pair, I'd hate to drive around looking like I've been in a bar fight,

 

it's bad enough that I drive in lingerie and heels, skinned knuckles would just give everyone the wrong impression.

[moonchook]

hey mike i had similar problems with my RVR when it was still on the road, lacked power, blew smoke, my brother end up rebuilding the turbo with the rebuild kit on ebay from japan (was about $70) which got it boosting properly again, we had lots of oil up in the exhaust manifold before the turbo rebuild.

 

if you want to build an engine for it eventually i'd be more than happy to negotiate a price on the 7 bolt HSGR block and remaining engine bits thats sitting in my shed, pretty keen to get rid of it as I have no need for it now. its all stripped with only the crank and oil pump stuff in place so should save some labour for the machinist.

[Hyper_Mike]

Im looking to purchase a td05 if anyone has one, just to see if its the turbo thats leaking oil into the exhaust. I sent someone a pm on here who was selling a KLS one but they didnt reply. Anyone else got one?

Just wiggle the compressor. If it wiggles, rebuild it.

You crack me up.
