Hi all just wondering your throughs on the tb45 are I know they are thirst but what are they like are the reliable? How many kms have you got out of them? Any common problems?

The 4.5L is a pretty good donk in regards to reliability, thirsty bugger that's for sure. I'm pretty happy with my 4.5L auto wagon which also has LPG fitted. A little under powered when going up steep hills but other than that mine fly's on the open highway. Mine has 253000 odd K's on it has been regularly serviced doesn't use any oil or water doesn't blow any smoke and no signs of oil leaks, I have been told these engines are basically bulletproof much like the bigger 4.8L brother. If it ever comes to an engine rebuild I might look at fitting a supercharger or such just for that extra bit of grunt for the hills. I'm not aware of any common problems with the 4.5L at all.

I would buy a 250k kms 4.5 without a worry. I wouldn't touch a 3.0 litre with the same kilometres.
They are thirsty but they are also the most powerful engine of that era.

I have a 4.5 that has done just over 300,000Ks - they are tough and reliable but very thirsty. It will cruise all day at 110 but is a slug up hills and the auto, whilst strong, continually shifts up hills. If your budget can stretch to it I would get a 4.8 - much more usable power and no thirstier than a 4.5.

280 on the clock for mine. Just petrol not gas. Best thing I did was for a torque converter lock up kit. Saved a heap of fuel by doing it aswell

lufkin where did you get your torque converter lock up kit from and how much?

 

[Reikon]

make it yourself
2 5pin relays, a few meters of wire and a few switches
this is chaz' blog about his Lockup Trans Switch

 

[Bigfella65]

Thanks for that link, interesting reading.

 

[lufkin]

as Reikon said make it yourself, cost me probably $15 in parts and about 30min of time

Bigfella, I have 185000 on mine, auto and gas, had to replace a couple of gas converters. I want to keep it to 250000. have you had any head or auto issues?, Rod

 

[Bigfella65]

Hey Rod, Ive only had the vehicle for 9 months and in that time I have had no problems whatsoever. Auto is silky smooth, I did change the coolant when I bought it and no problems theree.

 

[rocketrod54]

Good news bigfella, i got mine at 70,000 and had a few overheating probs but new rad and viscous hub sorted that out, have changed auto oil twice and had to get tappets adjusted once. Auto oil is clean as and engine oil is pretty clean every 10,000 service. I have no oil leaks anywhere it is like new. I love it! But it is a bit of a slug with 2 ton caravan on the back.

Been wondering about doing my tappets, their a bit tick tick tick, from what other 4.5L Ive heard they all seem to do the same, so yer dunno really. I'm running 10/40 Castrol Magnetec oil.

 

[rocketrod54]

Tick tick is ok, they tighten up and idles rough when hot

Mine idles very nice on petrol when hot, a little rough when on LPG.

 

[rocketrod54]

Mine idles rough on petrol and good on lpg, depends on the tune i guess. Can any one offer more info on adjusting tappets on tb45 ?
