Outer Limits 4x4 Board

wondering how easy it is to do the piston rings on the GQ TB42,
she been very bad on blowing smoke, and losing compression
iv been told to hold off picking up standard rings just incase its bored out

also would doing the p-rings,and vrs kit and a carbie kit help out on feul consumption????


cheers matt

carbie kit would help with chewin juice, ur better off gettin the vrs kit seeing that the head and manifolds have to come off to do the rings, even if u dnt use the valve stem seals, unless there is a big price diffrence, 4.5 litre cruiser motors the valve stem seals are worth gold. since u are goin to all that trouble to do the rings may aswell do the bigend bearings aswell

Just curious how many kays has the old TB42 done.

Rod

well when i bought it the counter was stuck on 199999 but i played with it and got it to keep going since then it now read 236000 od ks, but im guessing over 300000



now big end bearings what are they worth then???

what is a reco replacement engine worth with warranty, ready to go in a day, and your driving agian without problems?

There's a mob in Brissy who import low k Jap engines and give warantee.

They have TB42's in stock, I think somewhere around $2,000 for the motor complete.

I would be going down that path. Rebuild would be worth more than the car from a Mechanic.

yah i just got a second hand low k's motor of here. They come up every now and then.

Or pull the thing apart and whack new rings in. Its only nuts and bolts lol (term used loosely haha)

do welsh plugs to while you have it all apart, bearings should be bout $150 for mains n big ends, maybe $250 for gasket kit n $50 for welsh plugs. give or take a few $

yeah im kinda on a budget of under 500

and im leaving the motor in to do it

they are my two big probs $$$ and space

i could leave it together and throw in axado or what ever its call about 200 bucks for 3 tubs for a motor

Would this be fitted??
Also have they got more HP than the standered motor?

aaah. no

as it says. thats a used low klm engine. stock standard. plus fitting.

unless you can rebuild it yourself your better off get a 2nd hand motor and wack it in. they are near bullet proof anyway. its mainly poor maintenance that kills them.

yeah but who has 2000 laying around


cheaper to do rings for me,

trouble is youll spend more rebulding it if you do it properly. head check, vrs, rings, hone, big ends, mains, clutch etc etc..

2k is nothing really, people spend that on a head port and polish.if you rebuild it you may spend more, you might spend less. depends on who youknow or what you can do your self i spose. its a fun process but can get costly. all comes down to what you want, cheapest option is too get a 2nd hand motor. they have been on here for 600-800, low klm and complete

2k to me is huge since i only take home 450 a week as an apprntice, and ya pay all ya rent and bills and suport the kiddy how much ya reacons left?? hehehe

i can do all myself i have no problems with that , i just want to fix the problem not half the car if ya under stand what im saying- if its not broke dont fix it

anyways it my take on it

if your keen to do, id say go for it, $2000 is pretty steep for a used motor, they say low ks, but they will tell you anything to sell em. motors dont come with odemeters like whole cars, so you are at the sellers mercy. even if it costs $2000 to fully rebuild it properly. at least then you know for sure its a fresh motor that will last the distance.

piston rings $55
big ends $40

pistons $300
timing chain $12
mains $40
full gasket $200
cam bearings $18


it cost me, doing all the work myself
$700 for parts including welch plugs , and consumables oils etc
$800 for machining incuding grinding cam and lifters, machining flywheel and rebuilding head, grinding crank , boring block , fitting cam bearings and fitting pistons.
all up including a good clutch kit $400 and beer

it would have cost $2000
